Our verdict on ProofLayer
ProofLayer is an AI security platform for teams testing LLM applications, multi-agent systems, RAG pipelines, and MCP servers. It runs automated attack campaigns against LLM APIs, agent orchestrators, MCP servers, RAG pipelines, and custom targets. Coverage includes prompt injection, jailbreaks, data exfiltration, tool abuse, RAG poisoning, and memory injection. The product fits security, engineering, and compliance teams that need recurring adversarial testing across AI systems rather than a one-time review.
Its strongest differentiator is the combination of autonomous campaigns, scheduled or continuous red-teaming, and verified exploit replay traces. These traces support vulnerability reports and audit evidence, while the local coding-agent and MCP scanner extends testing beyond hosted applications. The Community plan includes a security scanner with CLI and MCP, 1,700+ detection rules, prompt injection probes, MCP tool testing, a community rule library, and MIT licensing. Integrations include LangChain, OpenAI Agents SDK, CrewAI, AutoGen, Semantic Kernel, and Pydantic AI, giving teams options across several agent frameworks.
ProofLayer offers web and self-hosted deployment, with hybrid deployment supported for the category. The free Community plan suits teams that want to evaluate scanning, customize tests, or contribute to the rule library. Enterprise adds continuous autonomous red-teaming, proof-of-exploit reports, compliance reporting, SSO/SAML integration, SLA guarantees, and a CISO executive portal; pricing is custom. Choose ProofLayer when continuous coverage and evidence for AI-specific attacks are priorities. Teams seeking broad, non-AI application security testing or a published numeric enterprise price should consider a different type of tool.
