SECURE AI
Secure AI Means Real Time Governance
Agents read documents, call tools and act on real systems. PurpleSec aligns your AI program to regulatory standards, then enforces governance at every prompt, response and agent action.
Defiance AI™ Is Aligned With NVIDIA's Open Agent Safety Platform
NVIDIA launched the platform on 28 September 2026 to secure autonomous agents from testing through deployment.
OpenShell
Open-source runtime security and policy enforcement, applied from outside the agent.
NVIDIA Sentry
Hardware monitoring that quarantines a misbehaving agent in milliseconds.
Full-Stack Governance
Controls across software, hardware and AI infrastructure.
What It Means For You
Policy enforced outside the agent is the new standard. Defiance AI™ works this way today.
One Research Finding Prevails:
Agent Actions Must Be Managed In Real Time
5%
attack success with runtime policy, against 35% for prompt-only defense.

added per tool call by runtime enforcement. Real time is practical.
Governance You Can Trust
Defiance AI™ is mapped to recognized frameworks, so it absorbs each new rule without starting over.

AI Risk Lives In The Interaction
That Is Where We Secure It
A policy on paper cannot stop an agent mid-task. Our approach rests on five commitments, from the first assessment to live enforcement.
Protection
Protect every interaction, wherever AI is used.
Visibility
See AI activity across people, agents and systems.
Control
Apply intelligent controls in real time, without disrupting work.
Partnership
A partner, not a vendor. The engineer who onboards you stays.
Transparency
We publish our reasoning, including where our own defenses fall short.
Not sure where your AI stands? Start with a risk assessment.
Four weeks. A risk register, a shadow AI inventory and a 90-day plan you can take to the board.
Secure AI Begins With A Charter
Most organizations know who owns an AI system. Few know who owns the important decisions.
AI Decision Authority Charter
- → Principles become decision rights
- → Monitoring becomes intervention
- → Committees become accountable owners
Frequently Asked Questions
What Does Secure AI Mean At PurpleSec?
It means AI is governed while it runs, not only on paper. We align your program to recognized frameworks, assign clear decision owners, and enforce policy on live AI traffic with Defiance AI™.
Which Frameworks Do You Align To?
NIST AI RMF, ISO/IEC 42001 and the EU AI Act for AI risk and governance. The OWASP Top 10 for LLM and Agentic Applications and MITRE ATLAS for AI security. We also track the draft NIST Cyber AI Profile and the CSA AI Controls Matrix.
How Does This Relate To NVIDIA's Open Agent Safety Platform?
NVIDIA’s launch confirms where agent security is heading: runtime policy, enforced from outside the agent. Defiance AI™ applies that principle to the AI tools and agents your teams already use. We are not claiming an integration with NVIDIA.
What Is An AI Security Charter?
A short document for each important AI use case. It names who approves, changes, pauses and restarts the system, and which triggers force action. It is tested in tabletop exercises so it works during a real incident.
Where Should We Start?
With the AI Risk Assessment. In four weeks you get a risk register, a shadow AI inventory and a 90-day plan. It shows which use cases need a charter first.
Do We Need Defiance AI™ To Work With PurpleSec?
No. Our advisory services stand on their own. Defiance AI™ is the product that enforces the policies they produce. You can add it at any point.
