Lakera vs CalypsoAI

Both compete in Runtime Enforcement & Guardrails. Lakera positions itself as “AI-native security platform guarding GenAI apps against prompt attacks and data loss”, while CalypsoAIleads with “Full-lifecycle inference-layer security and guardrails for enterprise AI”. The table below compares what each publishes.

Where Lakera pulls ahead

Security teams needing continuously updated, model-agnostic runtime protection for GenAI apps

Where CalypsoAI pulls ahead

Security and risk leaders in large or regulated enterprises needing model-agnostic runtime controls plus governance

Both map to EU AI Act, NIST AI RMF, so framework coverage alone will not separate them — the decision usually comes down to who operates the tool and how it fits your existing stack.

Best forSecurity teams needing continuously updated, model-agnostic runtime protection for GenAI appsSecurity and risk leaders in large or regulated enterprises needing model-agnostic runtime controls plus governance
LimitationsNow part of Check Point, so roadmap and packaging may shift toward that portfolio; focused on security rather than broad GRC/compliance workflow toolingNow being absorbed into F5, so independent roadmap and packaging may change; enterprise-oriented pricing and deployment; less suited to small teams

Which should you shortlist?

Choose Lakera if security teams needing continuously updated, model-agnostic runtime protection for GenAI apps

Choose CalypsoAI if security and risk leaders in large or regulated enterprises needing model-agnostic runtime controls plus governance

Neither is a substitute for a governance program. Whichever you pick, you still need people who can define the policies the tool enforces.
