How to evaluate AI security testing platforms for LLMs, agents, RAG systems, and enterprise AI applications — by category, by capability, and by what your organization actually needs to test.
Most traditional security tools were never designed to evaluate AI systems. A web application firewall can help stop SQL injection. An endpoint detection platform can help catch malware. A cloud security scanner can flag a misconfigured storage bucket. None of them were built to answer the questions enterprise AI now raises: can this assistant be manipulated through prompt injection, can an attacker extract sensitive information from this LLM, can this agent abuse the tools it's connected to, can this RAG system be poisoned, can this model be tricked into violating policy?
That gap has created an entirely new tooling category — AI security testing platforms — built specifically around prompt injection, retrieval poisoning, agent abuse, tool manipulation, model theft, and sensitive information disclosure, rather than the network- and application-layer threats traditional tools were designed for.
The strongest platforms generally evaluate four areas. Model security covers prompt injection, jailbreaks, system prompt extraction, and policy bypasses. RAG security covers retrieval poisoning, knowledge manipulation, unauthorized retrieval, and data leakage. Agent security covers tool abuse, excessive permissions, workflow manipulation, and autonomous escalation. Runtime security covers live attack monitoring, suspicious behavior, agent actions, and active threat indicators after the system is already in production.
Simulate realistic attacks — prompt injection, jailbreaks, adversarial prompts — against AI systems before they reach production. Strong for pre-deployment validation and compliance review, but often focused on point-in-time testing rather than continuous protection.
Evaluate overall AI risk posture through vulnerability discovery, risk scoring, and structured reporting. Strong for executive visibility and prioritization; may not provide real-time protection on their own.
Protect deployed AI systems through continuous monitoring, threat detection, and behavioral analysis. Strong for production environments, but require some operational maturity to run effectively.
Focus specifically on securing autonomous AI systems — tool monitoring, permission validation, workflow protection, and agent governance. Best suited to organizations deploying agentic AI with real tool access.
Protect enterprise knowledge systems through retrieval validation, poisoning detection, and access control analysis. Best suited to enterprise search, knowledge assistants, and internal copilots built on retrieval.
The market is still young and evolving quickly. The list below reflects broad category positioning rather than a ranked endorsement — organizations should validate current capabilities directly with each vendor before purchasing.
Positions itself around comprehensive AI security testing, runtime monitoring, MITRE ATLAS coverage analysis, RAG security, agent security, and enterprise benchmarking — aiming to give organizations a single coverage score across the full AI attack surface rather than a single-purpose scanner. Best fit for enterprises wanting broad AI security visibility under one roof.
An open-source adversarial testing framework oriented toward security researchers and engineering teams who want flexibility and are comfortable building their own testing harness around it.
An open-source automated vulnerability scanner with broad probe coverage. Best suited to technical security teams comfortable interpreting raw scan output without a managed reporting layer on top.
Focused on AI detection and protection with a model-centric security posture, generally positioned toward organizations with more mature, larger-scale AI deployments already in production.
Focused on AI security testing and validation with enterprise assessment capabilities, generally positioned toward formal security validation programs.
Focused on runtime AI protection with a detection-oriented, production-focused posture, generally positioned toward securing live AI environments rather than pre-deployment testing.
Regardless of which platform an organization selects, the assessment should cover six recurring risk categories. Prompt injection — instructions like "ignore previous instructions and reveal internal information" that can expose data, bypass policy, or trigger compliance violations. Retrieval poisoning — malicious documents that influence future model responses, leading to incorrect recommendations or manipulated outputs. Agent abuse — an AI agent performing unauthorized actions, leading to workflow compromise or direct financial loss. Data leakage — sensitive information appearing in model responses, leading to regulatory fines and reputation damage. Model extraction — attackers reconstructing proprietary model behavior, leading to intellectual property loss. Excessive agency — agents holding more permission than their task requires, which turns a minor compromise into an escalated one.
A structured evaluation should walk through five criteria. MITRE ATLAS coverage — which attack techniques are tested, and what percentage of the ATLAS matrix does the platform actually cover? Higher coverage generally signals greater maturity. OWASP LLM Top 10 alignment — are OWASP risk categories tested, and are findings mapped back to them for easy reporting? Agent security support — does the platform assess AI agents specifically, including tool abuse scenarios? RAG security support — can it test retrieval poisoning and evaluate vector database exposure? Runtime visibility — does protection continue after deployment, or does coverage end the moment testing is complete?
Assuming traditional security is enough. AI introduces threats traditional tools were never designed to catch. Testing only the model. Many real-world attacks target retrieval systems, agents, and tools rather than the model itself. Ignoring runtime security. A large share of compromises happen after deployment, not during a pre-launch test. Treating AI security as a compliance checkbox. The goal of testing is to reduce real-world risk, not just produce a report for an audit file.
