AI Red Team Maturity Model (Professional)
A structured maturity model for assessing and advancing the capabilities of AI red team programs across five progressive levels.
Overview
Maturity models exist for software development (CMMI), for organizational security (BSIMM, OpenSAMM), and for incident response (the SIM3 model). AI red teaming, despite its growing importance, has lacked a comparable framework — leaving teams to self-assess against vague criteria or, worse, to confuse activity with capability.
AI red teaming is a young discipline. Most organizations are still figuring out what their AI red team should do, let alone how well they should do it. Unlike traditional penetration testing, which has decades of methodology refinement and clear competency standards, AI red teaming lacks widely adopted frameworks for measuring program capability and progress.
This creates a practical problem: without a maturity model, AI red team leaders cannot objectively assess where their program stands, identify the highest-impact improvements, or communicate progress to leadership. Teams get stuck in patterns — running the same types of tests against the same types of systems — without a clear path to more sophisticated capabilities.
This article presents a five-level maturity model for AI red team programs, covering six capability dimensions. Each level has specific, observable criteria that distinguish it from the levels below. The model is designed to be prescriptive enough to drive concrete improvement plans while flexible enough to apply across different organizational contexts and AI deployment patterns.
Maturity Model Structure
The model evaluates AI red team programs across six capability dimensions, each with five maturity levels:
Dimensions:
1. Methodology & Planning
2. Technical Capabilities
3. Tooling & Automation
4. Reporting & Impact
5. Research & Innovation
6. Organizational Integration
Levels:
Level 1: Initial (ad hoc, reactive)
Level 2: Developing (basic processes established)
Level 3: Defined (standardized, repeatable)
Level 4: Managed (measured, optimized)
Level 5: Leading (innovative, industry-contributing)
Dimension 1: Methodology and Planning
This dimension assesses how systematically the red team plans and executes engagements.
Level 1 — Initial: Engagements are ad hoc. Testing is performed without a structured methodology. Scope is defined informally ("test the chatbot"). No consistent approach to threat modeling AI systems. Findings are reported as individual issues without connecting them to attack chains or business impact.
Level 2 — Developing: The team uses a basic engagement framework: scoping documents define what will be tested, a checklist of common AI attack types guides testing, and findings are categorized by type. However, the methodology is not adapted to different AI system architectures. The same checklist is used for an LLM-based chatbot and a fraud detection model.
Level 3 — Defined: Methodology is differentiated by AI system type. The team has distinct approaches for LLM systems, classification models, recommendation systems, and generative models. Threat models are produced for each engagement, and testing is prioritized based on the threat model. Engagement planning includes rules of engagement, success criteria, and communication protocols.

}
return tools.get(category, ["manual"])Level 4 — Managed: Methodology is data-driven. The team tracks metrics on which attack categories produce the most findings, which techniques are most effective against different system types, and how engagement outcomes correlate with engagement planning quality. This data feeds back into methodology refinement. Engagement plans are reviewed against historical data to optimize time allocation.
Level 5 — Leading: The team develops and publishes novel methodology. They contribute to industry standards (e.g., OWASP, NIST AI RMF), create frameworks that other organizations adopt, and continuously evolve their approach based on emerging research. The methodology incorporates attack categories that do not yet have public proof-of-concept exploits, based on the team's own research.
Dimension 2: Technical Capabilities
This dimension assesses the range and depth of attacks the team can execute.
Level 1 — Initial: Testing is limited to running automated tools (e.g., running garak against a chatbot) without understanding the underlying techniques. Results are accepted at face value without validation or deeper investigation.
Level 2 — Developing: The team can execute standard attacks from published research: basic prompt injection, simple adversarial examples using toolkits, and standard jailbreak techniques. They can adapt published techniques to their specific systems but cannot develop novel attacks.
Level 3 — Defined: The team can perform attacks that require understanding of the target system's architecture. This includes white-box adversarial attacks (requiring model access), training pipeline manipulation (requiring understanding of data flows), and model extraction attacks that are adapted to the target's specific API and rate limiting.
Level 4 — Managed: The team can execute sophisticated multi-stage attacks that chain multiple techniques. For example: using prompt injection to gain access to a RAG system's document store, poisoning documents in the store, and then using the poisoned documents to escalate access in a downstream system. The team can also evaluate novel model architectures for security properties without relying on published attack code.
Level 5 — Leading: The team discovers new vulnerability classes and develops new attack techniques. They can evaluate cutting-edge AI systems (new model architectures, new training techniques, new deployment patterns) before published attack research exists. They contribute novel techniques to the research community.
Dimension 3: Tooling and Automation
Level 1 — Initial: Testing uses only manual techniques and general-purpose tools (curl, Python scripts). No custom tooling exists.
Level 2 — Developing: The team uses established open-source tools (garak, ART, TextAttack, promptfoo) and has basic scripting to automate repetitive tasks.
Level 3 — Defined: The team has custom tooling for their organization's specific AI systems. This includes automated test suites that run in CI/CD, custom prompt injection payloads tuned to the organization's models, and reporting tools that integrate with the vulnerability management system.

main()Level 4 — Managed: Tooling generates metrics and trend data. The team has dashboards showing test coverage over time, regression detection across model versions, and comparative analysis of model security properties. Tools are integrated into the organization's security operations workflow.
Level 5 — Leading: The team develops and releases open-source tools that advance the state of the art. Internal tooling handles novel attack categories that commercial tools do not cover. Automation handles the majority of routine testing, freeing human effort for novel research and complex multi-stage attacks.
Dimension 4: Reporting and Impact
Level 1 — Initial: Findings are reported as individual bugs in a ticket system. No consistent format, no severity framework, and no tracking of remediation.
Level 2 — Developing: Findings follow a consistent report format with severity ratings. Reports include reproduction steps and remediation recommendations. However, findings are still reported as individual issues rather than connected attack narratives.
Level 3 — Defined: Reports tell attack stories — they connect individual findings into attack chains that demonstrate business impact. Reports include executive summaries for non-technical stakeholders, detailed technical appendices for engineering teams, and specific remediation guidance prioritized by risk.
Level 4 — Managed: The team tracks finding trends, remediation timelines, and the impact of their work on the organization's AI security posture. Reporting includes quantitative risk assessments and before/after comparisons that demonstrate program value. The team can show that their work has reduced the organization's AI attack surface by measurable amounts.
Level 5 — Leading: The team's reporting influences industry standards and regulatory frameworks. They publish case studies (appropriately anonymized), contribute to vulnerability taxonomies, and their findings drive changes in AI development practices beyond their own organization.
Dimension 5: Research and Innovation
Level 1 — Initial: No research activity. The team relies entirely on published techniques and tools.
Level 2 — Developing: Team members read and discuss current research papers. They can implement published attacks from paper descriptions.
Level 3 — Defined: The team conducts internal research — developing new attack variations, testing novel techniques, and evaluating the applicability of academic research to their organization's systems. Research time is allocated (e.g., 10-20% of team capacity).
Level 4 — Managed: The team publishes external research (blog posts, conference talks, papers) and contributes to open-source projects. They have established relationships with academic researchers and participate in industry working groups.
Level 5 — Leading: The team drives the research agenda in their focus areas. They discover new vulnerability classes, develop new testing methodologies adopted by other organizations, and are recognized as a leading voice in AI security research.
Dimension 6: Organizational Integration
Level 1 — Initial: The red team operates in isolation. ML teams may not know the red team exists or how to engage them.
Level 2 — Developing: Formal engagement processes exist. ML teams can request red team assessments and know how to file requests. However, security is still seen as a gate rather than a partner.
Level 3 — Defined: The red team is integrated into the AI development lifecycle. They participate in design reviews, have defined touchpoints in the deployment process, and maintain ongoing relationships with ML teams. A security champion program exists.
Level 4 — Managed: AI security is embedded in organizational culture. ML teams proactively seek security input, and security considerations are part of standard design processes. The red team has influence over AI development practices and architecture decisions.
Level 5 — Leading: The organization is recognized externally for its AI security practices. The security program influences industry best practices, and the red team's integration model is studied by other organizations.
Maturity Assessment Process
Self-Assessment Questionnaire
For each dimension, rate your program on each criterion. A dimension's level is the highest level where all criteria are met:
ASSESSMENT_CRITERIA = {
"methodology": {
1: [
"We perform some form of AI security testing",
"We have at least one person with AI security knowledge",
],
2: [
"We use a written checklist for AI security testing",
"Engagements have defined scope documents",
"Findings are categorized by attack type",
],
3: [
"Our methodology differs by AI system type",
"We produce threat models for each engagement",
"We have documented rules of engagement",
"Testing is prioritized based on threat model",
],
4: [
"We track engagement metrics and use them to improve methodology",
"Historical data informs test planning and time allocation",
"We regularly review and update our methodology based on results",
],
5: [
"We have published our methodology or contributed to industry standards",
"Our methodology covers attack categories not yet in public research",
"Other organizations have adopted elements of our approach",
],
},

}Key Takeaways
A maturity model provides the vocabulary and framework for honest assessment of an AI red team program's capabilities. The most common failure mode is overestimating maturity — running automated tools and reporting the output is Level 1, not Level 3, regardless of how many findings it produces. Real maturity shows in methodology differentiation, multi-stage attack capability, data-driven improvement, and demonstrable organizational impact.
Organizations should target Level 3 across all dimensions as a baseline for any program that claims to provide meaningful AI security assurance. Levels 4 and 5 are appropriate for organizations whose core business depends on AI systems and who face sophisticated adversaries. The path to maturity is incremental — each level builds on the previous one, and skipping levels creates fragile capabilities that collapse under pressure.
The maturity model is a diagnostic tool, not a goal in itself. The purpose of measuring maturity is to identify the highest-impact improvements and allocate resources accordingly. An organization that achieves Level 3 across all dimensions and stops improving is not mature — it is stagnant. The AI threat landscape will continue to evolve, and the maturity model should be recalibrated annually to ensure that its criteria reflect current threats, available tools, and industry expectations.
