Head-to-head comparisons between AEGIS and other AI agent safety projects.
Most AI agent safety projects solve one layer of the stack. Lakera Guard is a hosted commercial detector service. Guardrails AI validates structured output.

Seven open-source tools you can actually deploy for AI agent safety — what each one does well, what it misses, and how to compose them.
Load-bearing stat: Of the major open-source LLM safety projects (NeMo Guardrails, LangChain, Guardrails AI, Rebuff, ProtectAI, AEGIS, Wallaroo), only AEGIS combines parameter-level taint, cryptographic audit, and self-host gateway.

Load-bearing stat: Healthcare and fintech buyers reject 4 of 5 SaaS-only guardrail vendors in security review. Self-host (or open-core hybrid) wins by default in regulated verticals.
