AI Security Levels

Organizations adopting AI often ask: “When should I add AI to my existing pentest? When does it need its own AI penetration testing assessment? And when do I need full AI red teaming or adversarial simulation?”

The answer depends on your AI risk maturity, deployment model, and business impact.

The AI Security Readiness Framework outlines a clear path, from essential AI penetration testing safeguards to continuous, automated assurance, for systems ranging from simple LLM features to autonomous, multi-agent architectures.

1. For Early Adoption: Add-On AI/LLM Pentest for Lightweight AI Penetration Testing

When you are adding your first AI capability, such as a simple chatbot or generative feature, an Add-On AI/LLM Pentest acts as focused AI penetration testing wrapped into your existing application, mobile, or API pentest.

  • Best For: Traditional apps where AI is a feature rather than the core product; powered by a commercial foundation model; no tools or long-term memory.
  • Goal: Bring AI inputs and outputs into scope to uncover prompt-level and contextual risks early.
  • Example Checks: Prompt injection and jailbreak attempts, refusal/overshare validation, output sanitization before downstream use.
  • Evidence Produced: An add-on report integrated into the main pentest, detailing the AI paths tested and validated findings.
Mapped to Level 1: Baseline in the Checklist

2. For Expanding Risk: Standalone AI/LLM Pentest Plus AI Red Teaming

As AI becomes core to your product or touches sensitive data, you need deeper, framework-aligned assurance. A standalone AI/LLM pentest provides structured AI penetration testing to verify controls and outputs against recognized standards, while AI red teaming stress tests for behavioral and policy failures that traditional pentests miss.

  • Best For: Enterprise LLMs (single or multiple) or AI features that access sensitive data or internal systems and require audit-ready AI penetration testing and AI red teaming to support compliance (for example, EU AI Act, NIST AI RMF).
  • Goal: Combine structured testing and adversarial simulation to validate both system security and behavioral safety.
  • Example Checks: Core LLM risks (OWASP Top 10), RAG context isolation, plugin/tool authorization controls, multi-turn misuse scenarios.
  • Evidence Produced: Compliance-aligned assessment and AI red team report with mapped controls and prioritized risks.
Mapped to Level 2: Managed in the Checklist

In short, AI penetration testing focuses on structured, checklist-driven validation of your AI and LLM surfaces, while AI red teaming explores creative, real-world misuse to expose safety and policy gaps you cannot capture with scripts alone.

3. For Agentic and Connected AI Systems: Combined AI Red Teaming + Bug Bounty

When your AI starts using tools, APIs, or other agents to execute real actions or access live data, traditional penetration testing and one-off AI penetration testing often fall short. Combining AI red teaming with AI Bug Bounty ensures continuous adversarial coverage for these agentic environments.

  • Best For: Multi-agent or tool-using AI systems (e.g., internal agents, MCP-based workflows, RAG with external data).
  • Goal: Detect and validate real-world risks such as tool misuse, goal hijacking, memory poisoning, or cross-agent exploitation, while sustaining coverage between releases.
  • Example Checks: Agent-to-agent impersonation, sandbox bypass attempts, context spoofing, unsafe tool invocations.
  • Evidence Produced: Validated, prioritized findings with severity trends and MCP audit-trail insights.
Mapped to Level 3: Hardened in the Checklist

4. For Frontier and Mission-Critical AI: Continuous Testing Programs

At the highest maturity level, AI systems are dynamic and often agentic, requiring 24/7 validation across behavioral and system boundaries. Continuous AI assurance blends scheduled AI red teaming, ongoing AI Bug Bounty, and automated Autonomous Testing and Drift Monitoring to extend your AI penetration testing beyond point-in-time checks.

AI Red Teaming provides scheduled, objective-based exercises to test high-impact misuse and emergent behavior. AI Bug Bounty extends that coverage continuously, sourcing live findings from the global security researcher community as models, prompts, and tools evolve. Autonomous Testing / Drift Monitoring introduces simulated adversarial traffic and telemetry to track long-term model behavior, agentic interactions, and safety metrics between human testing cycles.

  • Best For: Model builders and operators of multi-tenant or agentic AI systems.
  • Goal: Achieve measurable, repeatable AI assurance through continuous adversarial validation and policy evidence mapping.
  • Example Checks: Model exfiltration, poisoning and drift detection, agent-to-agent manipulation, memory poisoning, goal hijacking, and MCP hardening validation.
  • Evidence Produced: Monthly trend metrics, automated red team and bounty insights, and quarterly “defensibility packets” mapping results to various frameworks such as NIST AI RMF, ISO 23894, and EU AI Act compliance requirements.
Mapped to Level 4: Continuous in the Checklist

By the time your AI is in production, you should have a plan for:

Secure Your AI Innovation

Securing AI is a maturity journey. By aligning your testing program to your readiness level, you can build resilient AI systems that withstand both technical exploitation and behavioral drift. AI penetration testing, AI red teaming, and continuous AI assurance all have a clear place in that roadmap.
