The Importance of Addressing Adversarial Attacks on AI Systems

Posted on by styrk

Adversarial attacks are not a theoretical problem; they are a real and growing threat to AI models used in security contexts. The risks posed by these attacks—ranging from compromised data and unauthorized access to damaged reputations and financial losses—are too significant to ignore. For security organizations, ensuring the integrity of AI systems is not just about maintaining operational effectiveness; it’s about upholding their mission to protect clients and maintain trust. If left unaddressed, these attacks can have dire consequences, undermining not only individual organizations but also  broader societal trust in AI systems.

Understanding adversarial attacks

Adversarial attacks involve subtly manipulating input data to deceive AI models into making incorrect predictions or classifications. These perturbations are often imperceptible to human observers but can lead to significant errors in AI outputs. For instance, altering a few pixels in an image can cause a computer vision system to misclassify objects, while slight modifications to input data can trick natural language processing models into generating misleading or harmful responses.

The ripple effect of ignoring adversarial threats

Addressing these vulnerabilities is not just a best practice—it’s a fundamental requirement in the modern security landscape.

If left unaddressed, the impact of adversarial attacks on AI models can be far-reaching and severe for organizations that rely on AI for security:

Erosion of model accuracy and reliability:

Adversarial attacks are designed to manipulate AI models into making incorrect predictions or classifications. In a security context, this could lead to the detection of false positives or, worse, the failure to detect actual threats. For example, an adversarial attack might trick a cybersecurity model into labeling a malicious action as safe, thereby allowing harmful activities to proceed unchecked. Over time, this degrades the model’s reliability, rendering it ineffective for security applications.

Compromised security systems:

In security-critical applications, such as biometric authentication or surveillance systems, adversarial attacks can lead to unauthorized access or failure to detect threats. For example, an attacker could manipulate facial recognition inputs to bypass security checks, posing significant risks to sensitive facilities.

Data breaches and unauthorized access:

When adversarial attacks compromise security models, attackers can exploit these vulnerabilities to bypass authentication systems or access restricted data. A common adversarial tactic is manipulating facial recognition models to gain unauthorized access or deceive surveillance systems. In sensitive environments such as financial institutions or government facilities, unauthorized access due to AI model tampering could lead to catastrophic breaches of confidential information.

Financial losses and fraud:

In the financial sector, AI models are used for fraud detection, algorithmic trading, and credit scoring. Adversarial attacks can manipulate these models to approve fraudulent transactions, disrupt markets, or incorrectly assess credit risks, leading to substantial financial losses and destabilizing economic systems.

Erosion of trust:

As AI systems become more embedded in daily life, public trust is paramount. High-profile failures due to adversarial attacks can erode confidence in AI technologies, hindering adoption and innovation. This mistrust can be particularly damaging in sectors like autonomous vehicles or healthcare, where safety and reliability are critical.

Increased operational costs and resource strain:

Failing to address adversarial threats results in increased costs for security organizations. Adversarial attacks often go undetected until significant damage has been done, which can require extensive investigations, model retraining, and repairs to existing systems. The organization may also need to implement more robust monitoring and defense mechanisms retroactively, leading to higher costs and strained resources that could have been avoided with proactive defenses.

Legal and regulatory repercussions:

Organizations that fail to secure their AI models may face legal consequences. Regulatory bodies are increasingly focusing on AI governance, and negligence in safeguarding against adversarial attacks could result in penalties, lawsuits, or stricter regulations that limit operational flexibility.

Intellectual property theft:

Adversarial attacks can also be used to extract sensitive information from AI models, including proprietary data or trade secrets. This intellectual property theft can undermine competitive advantages and result in significant financial and reputational damage.

Damaged reputation and loss of client trust:

For security organizations, the trust of clients is paramount. An adversarial attack that results in data breaches, unauthorized access, or compromised security outcomes can severely damage an organization’s reputation. Clients depend on security providers to offer dependable protection, and incidents of compromised AI security models can result in a loss of confidence, damaged brand reputation, and even legal repercussions in cases of gross negligence.

Regulatory non-compliance and legal risks:

As regulations around AI use and data security tighten globally, failing to address adversarial vulnerabilities in AI models could lead to significant compliance risks. For example, organizations in the financial sector must adhere to strict regulations governing data protection and fraud prevention. If an adversarial attack on an AI-driven system leads to a security lapse, organizations could face regulatory penalties, legal liability, and loss of licenses to operate within specific sectors.

Proactive defense: Key measures to safeguard AI models

Rather than leave adversarial threats unaddressed, organizations must adopt proactive methods to safeguard their AI models:

Adversarial training:

This involves exposing AI models to adversarial examples during training, helping them learn to identify and counter adversarial patterns. By making models more resilient to manipulated inputs, organizations can enhance their defenses against attacks.

Robust model validation:

Before deploying AI models, security organizations should conduct thorough validation, including testing against known adversarial attacks. Regular evaluations can help uncover vulnerabilities, enabling timely adjustments before models are used in critical operations.

Model monitoring and anomaly detection:

Implementing monitoring systems can help detect unusual patterns or behaviors that may indicate an adversarial attack. Automated anomaly detection tools are critical for identifying these attacks early and minimizing potential damage.

Access control and model authentication:

By restricting access to the AI model and using model authentication mechanisms, security organizations can protect their models from unauthorized modifications or attacks. This also reduces the chance of internal adversarial threats.

Collaboration with security and AI communities:

Adversarial attack methods evolve rapidly, so staying informed through industry collaborations, academic research, and intelligence sharing with other security organizations is essential. By learning from others’ experiences and innovations, security organizations can stay ahead of emerging adversarial tactics.

Regular audits and compliance:

Regular audits and testing are essential to identifying and addressing vulnerabilities in AI systems, keeping them secure against emerging threats. Compliance with legal requirements, such as GDPR, HIPAA, or CCPA, ensures that AI practices meet regulatory standards. By continuously evaluating systems and aligning with regulations, organizations maintain robust security and minimize risks associated with AI deployment.

By adopting a proactive approach to adversarial defense, security organizations can reinforce their AI models against emerging threats, maintaining the reliability and safety that their clients expect and deserve.

Posted on by styrk

From privacy to fairness, companies that are developing artificial intelligence (AI) models need to balance innovation with responsibility. Here’s how organizations can navigate these concerns and ethically build AI systems:

Build transparency into your AI pipeline:

AI models often function as “black boxes”, making their decision-making opaque. To foster trust between developers and users, transparency should be built into the AI pipeline. Techniques like explainable AI (XAI) can clarify how models arrive at conclusions, and regular ethical audits can ensure accountability, helping to build confidence among consumers and stakeholders alike.

Mitigate bias and ensure fairness:

AI systems can unintentionally perpetuate biases found in their training data, affecting marginalized groups. Incorporating fairness metrics and testing models on diverse datasets can help identify and minimize bias, ensuring that the AI serves all users equitably.

Prioritize data privacy:

Handling sensitive data is a critical ethical issue, especially with privacy regulations like General Data Protection Regulation (GDPR) in place. Techniques such as federated learning, differential privacy, and encryption can secure personal information during training and deployment, helping maintain compliance while protecting users.

Create an ethical AI governance framework:

Ethical AI development is a continuous process that requires clear governance frameworks. Establish an AI ethics board to guide model development and ensure alignment with evolving regulatory landscapes and ethical standards.

Foster human oversight:

AI should augment, not replace, human judgment—especially in high-stakes scenarios. Building human-in-the-loop systems ensures that experts can intervene when necessary, maintaining a balance between automation and accountability.

Promote ethical AI through education and awareness:

Organizations must foster a culture of ethical responsibility by educating teams about the implications of AI. Regular training and open dialogue around AI ethics can prevent issues from arising.

Protect Your Language Models from Prompt Injection Attacks

Posted on by styrk

Large language models (LLMs) are revolutionizing industries by enabling more natural and sophisticated interactions with AI. One of the most pressing concerns in this domain is the risk of prompt injection attacks, where malicious actors manipulate the inputs (or “prompts”) given to LLMs to exploit vulnerabilities, leading to unintended or harmful outputs. 

The flexibility of LLMs is both their strength and their weakness. While LLMs are adept at understanding and generating text across a wide range of contexts, they can be manipulated if not properly safeguarded. For businesses relying on LLMs, prompt security is not just a technical concern; it’s a vital aspect of trust, brand safety, and regulatory compliance.

What is prompt security and why is it crucial?

Prompt security refers to the safeguarding of inputs provided to LLMs, ensuring that these inputs do not lead to outputs that are unintended, harmful, or violate ethical guidelines. As language models become more integral to business operations, from customer service to content creation, maintaining the integrity of these models is critical. The consequences of a security breach can range from embarrassing outputs to severe reputational damage, regulatory violations, or even financial loss.

LLMs, particularly those based on generative AI like GPT, LLaMA, and others, are designed to process and generate text based on the prompts they receive. However, this capability also makes them vulnerable to prompt injection attacks, where attackers craft inputs that deceive the model into producing biased, toxic, or otherwise harmful content.  

How prompt injection attacks work

Prompt injection attacks exploit the way LLMs process and respond to input data. Here’s how these attacks typically work:

Manipulated inputs:

An attacker crafts a prompt designed to bypass the model’s usual content filters or exploit its inherent biases. For example, a seemingly benign question or statement might be engineered to provoke an offensive or incorrect response from the model.

Contextual confusion:

Some attacks leverage the model’s reliance on context, inserting misleading or harmful information that the model incorporates into its response.

Overloading with noise:

Attackers might inject gibberish text or excessive irrelevant data into the prompt to confuse the model. This can cause the model to produce incoherent or nonsensical outputs, disrupting the user experience and potentially leading to unintended consequences.

Cross-site prompt injection:

In more advanced scenarios, attackers might exploit vulnerabilities in web applications that use LLMs by injecting harmful prompts through user inputs, leading to unauthorized actions or disclosures.

Protecting your language models from Prompt Injection attacks

A multi-layered approach is essential to guard against prompt injection attacks. Key strategies include:

  • Input validation and sanitization: Filter and sanitize user inputs to block harmful prompts.
  • Contextual awareness: Train models to recognize and reject prompts that manipulate context.
  • Bias and toxicity filters: Check outputs for harmful content before delivering them to users.
  • Rate limiting: Implement mechanisms to detect and limit unusual input patterns.
  • Security audits and testing: Regularly audit for vulnerabilities and conduct penetration tests.
  • Continuous updates: Retrain models to recognize new attack patterns and improve resilience.

      Privacy-Preserving Methods in AI: Protecting Data While Training Models

      Posted on by styrk

      AI models are only as good as the data they are trained on. However, training models on real-world data often requires access to personally identifiable information (PII). Unchecked, AI systems can inadvertently expose or misuse sensitive data. With increased scrutiny and tightened compliance requirements due to regulations like the EU AI Act and GDPR, protecting this data is paramount.

      Styrk provides tools and frameworks to help enterprises protect sensitive data while training AI models, and can help your organization employ key privacy-preserving techniques:

      1 – Federated learning

      Federated learning is a decentralized approach where multiple devices or servers collaborate to train a model without exchanging raw data. Instead, models are trained locally on individual devices, and only the trained model parameters are shared. This technique is particularly useful in sectors like healthcare, where patient data must remain private and secure.

      2 – Differential privacy

      Differential privacy adds mathematical noise to data or results during AI training to obscure individual data points, while still allowing for the generation of meaningful insights. This approach is highly effective in preventing the identification of individuals within datasets.

      3 – Homomorphic encryption

      Homomorphic encryption allows AI models to perform computations on encrypted data without needing to decrypt it. This ensures that even during processing, sensitive data remains secure and unreadable.

      4 – Data anonymization

      Data anonymization is the process of removing or masking personally identifiable information from datasets before they are used in AI training. By anonymizing data, organizations can still train AI models without violating privacy regulations.

      5 – Synthetic data generation

      Synthetic data involves creating artificial datasets that closely mimic real data but contain no real personal information. This method allows organizations to train AI models on realistic datasets without risking privacy breaches.

      How Styrk can help you stay compliant and secure

      Our advanced data masking and anonymization tools help prevent re-identification of anonymized datasets, and assist in generating high-quality synthetic data that retains the essential properties of real datasets while ensuring privacy protection. With comprehensive privacy monitoring and adversarial attack protection, we help enterprises comply with regulations, while securing their AI systems against evolving threats.

      Explainability and Bias in AI: A Security Risk?

      Posted on by styrk

      In the rapidly evolving landscape of artificial intelligence, the concepts of explainability and bias are at the forefront of discussions about security and trust. As AI systems and large language models (LLMs) are increasingly integrated into various sectors, from healthcare to finance, ensuring these systems are both understandable and unbiased is crucial. But why are explainability and bias themselves considered security risks, and what can be done to mitigate these risks?

      The Importance of Explainability in AI

      Explainability refers to an AI model’s ability to understand and interpret the decisions made by its systems. For users and stakeholders to trust AI, they need to know how decisions are reached. In critical applications such as medical diagnosis or loan approvals, the inability to explain AI decisions can lead to mistrust and even harmful outcomes.

      Example: Healthcare

      Imagine an AI system used to diagnose diseases. If the system identifies a condition but cannot explain how it arrived at that conclusion, doctors may find it difficult to trust the diagnosis. Worse, if the AI is wrong, patients might receive inappropriate treatments, leading to severe consequences. Transparent AI models that provide insights into their decision-making process can help medical professionals make better-informed decisions, thus enhancing trust and safety.

      The Challenge of Bias in AI

      Bias in AI occurs when a model produces prejudiced outcomes due to flawed data or algorithms. Bias can manifest in various forms, such as racial, gender, or socioeconomic biases, and can significantly impact the fairness and equity of AI applications.

      Example: Hiring Practices

      Consider an AI system used for hiring employees. If the training data predominantly includes resumes from a specific demographic, the AI might learn to favor candidates from that group, perpetuating existing inequalities. Such bias not only undermines the fairness of the hiring process but also exposes companies to legal risks and reputational damage.

      Explainability and Bias as Security Risks

      Both explainability and bias directly impact the security and trustworthiness of AI systems. Unexplainable AI decisions can be manipulated or misinterpreted, leading to security vulnerabilities. For instance, if an AI system’s behavior cannot be understood, malicious actors might exploit this opacity to manipulate outcomes without detection.

      Bias, on the other hand, can erode the foundational trust in AI systems. Biased outcomes can lead to discriminatory practices, resulting in social and ethical issues that compromise the security and integrity of AI applications.

      Mitigating Risks with Explainability and Bias Management

      To address these challenges, it is essential to implement robust mechanisms that enhance the explainability of AI models and actively manage and mitigate bias.

      Approaches to Enhance Explainability:

      Model Transparency:

      Using interpretable models or providing explanations for complex models helps users understand AI decisions.

      Post-Hoc Explanations:

      Techniques such as LIME (Local Interpretable Model-agnostic Explanations) and SHAP (Shapley Additive Explanations) can be used to explain the outputs of black-box models.

      Human-AI Collaboration:

      Encouraging collaboration between AI systems and human experts ensures that AI decisions are validated and understood.

      Strategies to Mitigate Bias:

      Diverse Training Data:

      Ensuring that the training data is representative of all relevant demographics helps reduce bias.

      Bias Detection Tools:

      Using tools to regularly check for bias in AI models can help identify and correct prejudiced outcomes.

      Continuous Monitoring:

      Implementing continuous monitoring systems to track AI decisions and outcomes ensures ongoing fairness and equity.

      Historical data reuse: Unleashing the potential of unstructured data while preserving privacy

      Posted on by styrk

      Businesses and organizations generate vast amounts of unstructured data every day. This data often contains valuable insights that can inform future business decisions, improve efficiency, and drive innovation. However, much of this data remains untapped due to concerns surrounding privacy and data security. Organizations are reluctant to utilize or share historical data because it often contains sensitive or personal information, which, if mishandled, could lead to legal and reputational risks.

      This is where Styrk’s Cypher, a solution to identify and mask sensitive data from unstructured data sources (such as PDFs, Word documents, text files, and even images), steps in. Cypher ensures that organizations can safely reuse historical data without compromising privacy or security.

      The challenge: Valuable data trapped by privacy concerns

      For years, organizations have amassed huge volumes of unstructured data, including legal contracts, customer communications, medical records, financial reports, and more. Often, these documents contain personally identifiable information (PII), financial data, or other sensitive content that is subject to strict data privacy regulations.

      Because of these privacy concerns, historical data is often shelved or deleted to avoid compliance issues. Organizations face significant obstacles when it comes to extracting the valuable insights locked away in this data, especially without compromising privacy or inadvertently exposing sensitive information.

      Take the example of a healthcare provider organization wanting to conduct a study on past patient outcomes. The organization possesses decades of medical records, filled with valuable data, but it cannot reuse or share them without risking the exposure of patient identities and medical information. Manually anonymizing large datasets is time-consuming, prone to human error, and requires significant expertise in data security.

      The solution: Cypher for historical data reuse

      Cypher offers a powerful solution to this dilemma by enabling organizations to safely reuse historical unstructured data. By identifying and masking sensitive information automatically, Cypher helps organizations maintain compliance with privacy regulations while leveraging the information contained in their historical data.

      Cypher’s advanced algorithms can process and analyze a wide range of unstructured file types—be they text-heavy PDFs, word documents, or scanned image files. By recognizing patterns associated with sensitive data (like names, addresses, Social Security numbers, or credit card information), Cypher can accurately detect and mask such information across large datasets. This process allows organizations to reuse their historical data with full confidence that no sensitive data will be inadvertently disclosed.

      Key benefits of Cypher in historical data reuse

      Unlocking hidden value:

      With Cypher’s masking technology, organizations can safely access historical data that was previously off-limits due to privacy concerns. Whether it’s decades-old contracts, customer feedback, or archived financial data, these documents contain rich information that can be used for trend analysis, decision-making, and forecasting.

      Automated detection and masking:

      The solution eliminates the need for manual review by leveraging AI to automate the detection of sensitive data. Cypher scans unstructured data at scale, identifying PII and other confidential information that must be masked, drastically reducing the time and effort required to prepare data for reuse.

      Preservation of data integrity: 

      While Cypher effectively masks sensitive information, it maintains the structure and integrity of the underlying data. This ensures that historical data remains valuable for analysis, research, and reporting purposes, even after sensitive elements have been removed.

      Scalability:

      Cypher’s ability to process large volumes of data means that organizations can tackle historical data of any size. Whether a company is dealing with hundreds or millions of files, Cypher’s scalable solution can handle the task efficiently.

      Real-world example: A financial institution’s data dilemma

      Consider a financial institution that has been operational for over 50 years. The company possesses an enormous archive of customer transaction records, loan agreements, and financial reports stored as unstructured data. These documents contain vast amounts of business intelligence that could offer insights into market trends, customer behavior, and operational improvements.

      However, many of these files contain sensitive information such as account numbers, personal addresses, and financial details that must be protected. Historically, the institution has been unable to fully leverage this data for fear of violating privacy laws and exposing customers’ personal information. By implementing Cypher, the financial institution can securely process these files. Cypher scans the archive, identifies sensitive data, and applies masking techniques to anonymize it.

      Enhancing fairness in AI models: An HR-centered use case on bias identification and mitigation

      Posted on by styrk

      Rapid advancement of AI in recent years has made it easier for AI to enter numerous domains across organizations including finance, healthcare, law enforcement, and human resources (HR). However, as AI gets integrated into organizational operations, concerns arise about potential biases leading to unfair outcomes. 
      Real-world examples of AI bias, such as towards gender or race, emphasize the importance of responsible AI that adheres to AI regulation compliances like Equal Employment Opportunity Commission (EEOC) guidelines, National Institute of Standards and Technology (NIST) AI risk management, and others to ensure fairness and equity.

      The challenge: Ensuring AI fairness in HR operations

      The challenges faced by HR teams in integrating hiring practices with AI systems underscore the need for AI accountability. Although the potential advantages of quicker and more precise evaluations are clear, HR managers are rightly concerned about ensuring AI fairness and preventing negative impacts in the hiring process. 

      To combat biases, organizations must adhere to regulatory compliance standards set by the EEOC, which enforces laws prohibiting employment discrimination based on race, color, religion, sex, national origin, age, or disability. The EEOC AI regulation has also issued guidance on the use of AI and AI algorithmic bias to ensure fair and equitable treatment of all individuals in employment practices. 

      In a notable and recent example, Amazon experimented with an AI recruiting tool that was intended to streamline the hiring process by efficiently screening resumes. However, the tool developed a bias against women because it was trained on resumes submitted to Amazon over a decade—a period during which the tech industry was predominantly male. As a result, the AI system downgraded resumes that included the word “women’s” or came from all-women’s colleges*. Despite the neutral nature of the underlying algorithms, the training data’s inherent bias led to discriminatory outcomes. 

      This use case underscores the critical issue faced by many HR organizations: How can AI be leveraged to improve efficiency in hiring while maintaining AI fairness and avoiding AI bias? Will it be possible for the AI solution to deliver faster, more accurate evaluations of applicant qualifications than experienced HR specialists while adhering to AI fairness and AI bias standards?

These metrics offer a clear, visual representation of the improvements made in AI fairness and AI bias reduction.

      Real-world impact: Benefits of using Trust in HR processes

      Applying Trust to AI-supported applicant review system could yield significant benefits:

      Faster evaluations:

      By ensuring the AI model is free from AI bias, HR managers can confidently use it to speed up the initial screening process, allowing HR specialists to focus on more nuanced aspects of candidate evaluation.

      Improved accuracy:

      With bias mitigated, the AI model can provide more accurate evaluations of applicant qualifications, potentially surpassing the consistency of human evaluators.

      Fairness assurance:

      The comprehensive metrics provided by Trust can demonstrate that AI-supported systems meet or exceed fairness standards, ensuring no adverse impact on protected groups.

      Continuous improvement:

      Regular use of Trust can enable organizations to monitor and improve AI models over time, adapting to changing workforce dynamics and evolving definitions of fairness.

      In the quest for efficiency and accuracy, AI models play a crucial role in transforming HR processes.

      Safeguarding X-ray Scanning Systems in Border Security

      Posted on by styrk

      Rapid advancements in the realm of artificial intelligence (AI) and machine learning (ML) have ushered in unprecedented capabilities, revolutionizing industries from healthcare to transportation and  reshaping approaches to complex challenges like anomaly detection in non-intrusive inspections. Yet with great technological progress comes the real threat of adversarial attacks, which compromise the reliability and effectiveness of these AI models.

      Imagine a scenario where an AI-powered system creates synthetic data for computer vision at national borders. It creates an emulated X-ray sensor that can produce synthetic X-ray scan images similar to real X-ray scan images, and virtual 3D replicas of vehicles and narcotics containers. This set of images can be used to train the system to detect anomalies for application of global transport systems. For example, the system can be used in customs and border protection to identify narcotics and other contrabands in conveyances and cargo. However sophisticated this system, it is vulnerable if malicious actors exploit its weaknesses through adversarial attacks.

      Understanding adversarial attacks

      Adversarial attacks are deliberate manipulations of AI models through subtle modifications to input data. These modifications are often imperceptible to human eyes but can cause AI algorithms to misclassify or fail in their intended tasks. In the context of X-ray scan emulation and model classification, an adversarial attack could potentially introduce deceptive elements into images. For instance, altering a few pixels in an X-ray image might trick the AI into missing or misidentifying illicit substances, thereby compromising security protocols.

      The stakes: Why AI model security matters

      The implications of compromised AI models in security applications can be profound. Inaccurate or manipulated anomaly detection can lead to serious consequences; in the case of customs and border security, this could mean undetected smuggling of narcotics or other illegal items, posing risks to both public safety and national security. Here, safeguarding AI models from adversarial attacks is not just a matter of technological integrity but also a crucial component of maintaining public order and staying compliant with regulatory standards.

      Challenges in securing AI models – and how Styrk offers protection

      Vulnerability to perturbations:

      AI models are susceptible to small, carefully crafted perturbations in input data that can cause significant changes in output predictions. Styrk can identify vulnerabilities of the AI model and propose mitigation mechanisms to safeguard from such perturbations.

      Lack of robustness:

      If not carefully monitored, measured, and mitigated, AI models typically lack robustness against adversarial examples, as they are often trained on clean, well-behaved data that does not adequately represent the complexity and variability of real-world scenarios. Styrk can help you identify the kind of adversarial attacks your model might be susceptible to and suggest relevant mitigation mechanisms.

      Complexity of attacks:

      Adversarial attacks can take various forms such as: evasion attacks; where inputs are manipulated to evade detection, poisoning attacks; where training data is compromised, or any other such attack, necessitating comprehensive defense strategies. Most defenses in the market are designed to protect against specific types of adversarial attacks. When new attack techniques are developed, defenses can become ineffective, leaving models vulnerable to unseen attack methods. In contrast, Styrk’s Armor presents a comprehensive suite that scans the model to identify vulnerabilities in the model. It also offers a single proprietary, patent pending defense for adversarial attacks on traditional AI/ML models that covers a wide range of attacks.

      Resource constraints:

      Organizations may face limitations in terms of computational resources, time, and expertise required to implement robust defenses against a wide range of adversarial threats in their AI models. Especially in such scenarios, Styrk’s Armor offers an auto-scalable vulnerability scanning tool that can be used to identify potential vulnerabilities in the model and its proprietary defense mechanism proposes the best mitigation strategy that is practical across a wide range of attacks.
