Crashmire or Lakera: which one to choose?
Lakera provides guardrails that filter attacks in production, and was acquired by Check Point in 2025. Crashmire comes first: it finds where your agent gives in and fixes the cause.
| Lakera | Crashmire | |
|---|---|---|
| What is tested | Incoming and outgoing messages, filtered in real time (injections, data leaks). | Your agent's behaviour as it is (prompt, tools, rules) when its target is out of reach or someone tries to trick it: does it cross a line? |
| How it works | A security layer placed in front of your AI application, in production. | A service: you describe the agent, we replay it on several models and several runs. No access to your systems, nothing to install. |
| Who it is for | Security teams protecting applications already live. | Executives, risk and compliance, CISOs, business teams deploying an agent; from SMBs to large organisations. |
| What you get | Continuous filtering and alerts. | A report for management: flaws with how they happened, tested fixes (before / after), mapping to the AI Act and OWASP, a re-test included. |
| Price | On quote, part of Check Point's security offering. | Public prices: online from €490 excl. VAT for an SMB, €4,900 to €25,000 for a large organisation, continuous monitoring from €36,000 a year. |

Choose Lakera if…
- your agent is already live and you want an immediate safety net
- your main risk is booby-trapped messages from outside
- you already run Check Point
Choose Crashmire if…
- the risk also comes from the agent itself, under the pressure of a target
- you want to fix the cause (prompt, permissions, approvals), not only filter
- you want test evidence for the AI Act before going live
And both together?
Yes, they complement each other: the crash test removes flaws before going live, the guardrail filters what is left in production.
