Comparison
Prism vs Lakera
Side-by-side comparison of Prism and Lakera, written so it is useful even if we don't win the deal.
About Lakera
Lakera positions as an LLM security platform focused on prompt-injection defense and AI red-teaming. Their tooling (Lakera Guard, Lakera Red) is well-regarded for LLM-specific security testing and runtime protection. The trade-off is that observability and compliance-evidence layers are narrower than full-spectrum AI governance platforms.

When to pick which
Pick Prism
Pick Prism when you need the full operational surface — trace logging, quality evaluation, agent trajectories, audit exports — alongside guardrails and red teaming. Prism is the answer when compliance officers and CROs are buyers as well as security teams.
Pick Lakera
Pick Lakera when your immediate problem is LLM security specifically — prompt injection at the application boundary, or red-team testing for a specific high-risk model. Lakera is the right answer for security teams that want a focused LLM-security tool.
