TL;DR: Pen tests can confirm specific flaws, but ActiveFence says they do not show how an AI system holds up under adversarial pressure across data, workflows and response processes. AI security therefore depends on testing the whole environment, not only isolated defects.
Editorial analysis by NHI Mgmt Group, based on content published by ActiveFence: “If I Already Do AI Pen Testing, Why Do I Need Red AI Teaming?”.
Key questions
Q: Why do AI red teams focus on weaknesses instead of vulnerabilities?
A: Because a vulnerability is a discrete flaw, while a weakness is the broader pattern that lets an attacker succeed even when individual flaws are patched.
Q: How should security teams govern AI systems that can act without human approval?
A: Security teams should govern autonomous AI the same way they govern other high-risk identities, but with runtime enforcement instead of periodic review.
Q: What breaks when teams rely on AI pen testing instead of continuous DAST?
A: What breaks is coverage at development speed.
Practitioner guidance
- Define AI test scope around real attack paths Map data sources, preprocessing, model behaviour, integrations and human response paths before selecting the test boundary.
- Test alert triage and response, not just exploitation Include detection, escalation and communication in the exercise so the assessment checks whether SecOps recognises unusual behaviour and whether teams can stop the attack before it reaches its objective.
- Exercise poisoning and bypass scenarios Build scenarios for poisoned inputs, manipulated outputs and indirect prompt bypasses, because those paths reveal whether safety filters, monitoring and review processes work together under adversarial pressure.
Bottom line: AI penetration tests remain useful for proving specific defects, but they do not prove that the surrounding AI system can withstand adversarial pressure.

AI security now needs two different assurances, not one. A penetration test can prove that a specific technical flaw exists or is absent, but it cannot tell you whether the surrounding environment can absorb adversarial pressure. That makes red teaming a governance control, not a luxury add-on. Practitioners should treat the two methods as complementary evidence for different risk questions.
A few things that frame the scale:
- 92% of organisations expose NHIs to third parties, raising concerns about supply chain security, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How should security teams govern AI systems that can act without human approval?
A: Security teams should govern autonomous AI the same way they govern other high-risk identities, but with runtime enforcement instead of periodic review. That means tightly scoping tools, data, and actions; logging every material step; and making revocation and containment available while the session is still active. Static policy alone does not control machine-paced execution.
