Red Teaming April 2026

AI Red Teaming

What AI red teaming actually involves, how automated and manual approaches complement each other, and why point-in-time assessments are giving way to continuous runtime testing.


What AI Red Teaming Actually Involves

AI red teaming is the practice of systematically attacking your own AI system to find vulnerabilities before adversaries do. It encompasses jailbreak testing, prompt injection, adversarial input generation, multi-step attack chains, and safety-bypass attempts.

Unlike traditional penetration testing, which targets infrastructure and application code, AI red teaming targets the model’s behavior itself — the gap between what you intend the model to do and what it can be made to do under adversarial conditions.

The scope of a modern AI red team engagement includes:

Automated vs. Manual Red Teaming

Automated Red Teaming

Tools like PyRIT (Microsoft), Garak (NVIDIA), and autoredteam (GLACIS) run hundreds of attack patterns against a model in minutes. They cover known vulnerability classes systematically.

  • + Breadth: tests hundreds of attack categories
  • + Speed: full sweep in minutes, not weeks
  • + Reproducibility: same tests, every deployment
  • Limited at creative, context-specific attacks
  • Can miss multi-step social engineering chains

Manual Red Teaming

Human experts craft novel attacks tailored to your specific application context, data, and deployment. They bring creativity that automated tools lack.

  • + Depth: finds novel, application-specific flaws
  • + Context-aware: understands business logic
  • + Creative: invents attack chains tools don’t know
  • Expensive: $50K–$200K per engagement
  • Slow: weeks to complete, results stale fast

The most effective programs combine both: automated testing for continuous coverage and regression detection, manual testing for periodic deep-dives and scenario-specific validation.

Continuous vs. Point-in-Time Testing

Traditional security assessments are point-in-time: you run a pentest, get a report, fix the findings, and repeat next year. This cadence made sense when software changed quarterly. AI systems change constantly.

Between annual red team engagements, your AI system may have:

Each of these changes can introduce vulnerabilities that the last red team engagement didn’t test for, because those changes didn’t exist yet.

The Case for Runtime Red Teaming

Runtime red teaming embeds adversarial testing into the CI/CD pipeline and the production monitoring loop. Every model update triggers a battery of attack tests. Every new tool integration is probed for escalation paths. In production, a background adversarial process continuously challenges the system with evolving attack patterns — catching regressions and novel vulnerabilities as they emerge, not six months later.

Regulatory Requirements for AI Red Teaming

AI red teaming is no longer optional for regulated industries. Multiple frameworks now mandate some form of adversarial testing:

Framework Requirement Cadence
EU AI Act (Art. 55) Pre-release adversarial testing for high-risk and general-purpose AI Before deployment + ongoing
NIST AI RMF Red teaming as part of MAP and MEASURE functions Continuous recommended
Colorado AI Act Risk assessment including adversarial testing for high-risk systems Annual minimum
EO 14110 (US) Red teaming for dual-use foundation models Before public release

Continuous red teaming satisfies the “ongoing” requirements in these frameworks while also producing the documentation artifacts — test results, attack logs, remediation records — that auditors and regulators expect.

How GLACIS Approaches Red Teaming

GLACIS provides autoredteam, an open-source continuous red teaming tool that runs adversarial probes against any LLM endpoint. It covers the OWASP LLM Top 10 attack categories and maps findings to MITRE ATLAS techniques.

Mapped to OVERT controls ov-1.1 (adversarial testing), ov-1.3 (continuous validation), and ov-2.2 (framework compliance mapping).
