## Our take

What our shortlists say about the one we picked.

### [Check Point AI Agent Security](https://cybersectools.com/tools/check-point-lakera)

Best for: Runtime protection for AI apps and agents you build

It earns its place on the build side of this list, because it sits in front of the AI apps and agents your teams ship and blocks attacks as they happen. It fits mid-sized and large teams that build on several models, since one API call covers any app and LLM. Lakera is now part of Check Point, so ask how the roadmap and licensing will change inside the larger company.
