HiddenLayer FAQ
How does HiddenLayer's AI Runtime Security protect against adversarial threats in real-time?
HiddenLayer's AI Runtime Security acts as a firewall, continuously monitoring prompts, outputs, memory, and agent actions to detect and block adversarial threats such as prompt injection, data leakage, model theft, and unsafe tool use as they occur in agentic and generative AI applications.
What types of AI models and applications does HiddenLayer secure?
HiddenLayer secures agentic, generative, and predictive AI applications. This includes protecting against risks in both proprietary and third-party models, as well as safeguarding autonomous systems and multi-component pipelines (MCPs).
How does HiddenLayer address the challenge of 'shadow AI' within an organization?
HiddenLayer's AI Discovery module automatically identifies and maps all models, agents, datasets, and AI workflows across cloud environments, repositories, and applications. This provides comprehensive visibility into AI usage, eliminating shadow AI and enabling better governance and planning.
Can HiddenLayer integrate with existing enterprise security and development tools?
Yes, HiddenLayer offers native integrations with common enterprise systems, including CI/CD pipelines, MLOps platforms, Data Pipelines, and SIEM/SOAR solutions. This simplifies deployment and allows for seamless incorporation into existing security and development workflows.
What is the primary benefit of HiddenLayer's non-invasive AIDR solution for regulated industries?
The primary benefit of HiddenLayer's non-invasive AIDR (AI Detection and Response) solution for regulated industries is that it provides robust, real-time protection against adversarial attacks without ever needing to access a customer's sensitive data or proprietary models, which is crucial for maintaining data privacy and compliance.
How does HiddenLayer help organizations validate their AI defenses before deployment?
HiddenLayer's AI Attack Simulation module continuously red teams AI systems. It simulates various attacks like prompt injection, jailbreaks, data extraction, and adversarial abuse, allowing organizations to identify and fix weaknesses before their AI applications are deployed to production.
What specific risks does HiddenLayer mitigate in the AI supply chain?
HiddenLayer mitigates risks in the AI supply chain by scanning proprietary, vendor, and open-source models for malware, backdoors, CVEs, integrity issues, and inherited risks. This ensures that models are safe to use before they reach production, reducing exposure from unvetted third-party AI components.
How does HiddenLayer contribute to enterprise AI governance?
HiddenLayer contributes to enterprise AI governance by providing full visibility into where AI exists and how it is used, ensuring that only verified models enter production, and offering continuous validation as models evolve. This comprehensive framework helps manage risk and aligns AI adoption with visibility, compliance, and accountability.
