Failproof AI

End-to-end reliability for AI agents. Traces every run at the agent runtime, scores every finished session in the cloud with code checks, LLM judges and the eval set you already have (DeepEval, Ragas, promptfoo or your own), brought in as it is, finds where agents fail on its own, and lets you author and enforce a policy that stops the bad action in realtime - deployed on-prem or in the cloud.

Lakera

AI security firewall (Lakera Guard, part of Check Point). Real-time detection of prompt injection, jailbreaks, PII, and data leakage on LLM inputs and outputs, via an API.

Choose Failproof AI when

  • you run high-impact autonomous agents that take real actions
  • a wrong action is costly or irreversible
  • you need to stop failures at runtime, not just trace them
  • you want an end-to-end reliability solution, on-prem or cloud

Choose Lakera when

  • your main risk is prompt injection, jailbreaks, or data leakage
  • you want a dedicated LLM security firewall
  • you need best-in-class threat detection on model I/O

FAQ

Is Lakera an alternative to Failproof AI?

They cover different risks. Lakera secures the model against attacks (prompt injection, PII, jailbreaks) on LLM I/O. Failproof AI keeps the agent reliable - tracing runs, finding failure modes, and enforcing policy on agent actions. For security, Lakera is the specialist; for agent reliability, Failproof AI is.

Does Failproof AI do prompt-injection detection?

It has basic protection, but Lakera is the specialist there. Failproof AI focuses on agent-runtime reliability and enforcing what the agent does.

Can I use both?

Yes - Lakera for LLM security, Failproof AI for agent reliability.
