## Our take

What our shortlists say about each one.

### [Cloudflare API Shield](https://cybersectools.com/tools/cloudflare-api-shield)

Best for: Cloudflare customers protecting public APIs at the edge

It makes the list because it adds discovery, schema checks and leak scanning on a network you may already use, so there is little new to deploy. Its positive security model only lets through requests that match your schema, which works well if your OpenAPI specs are current. If they are not, or your APIs sit outside Cloudflare, weigh the schema upkeep and rerouting it would take.

### [Imperva API Security](https://cybersectools.com/tools/imperva-api-security)

Best for: Imperva WAF customers adding API discovery

Imperva earns a spot because it catches one user reading another user's data as it happens and can block it inline through the WAF you may already run. It suits you best if that WAF is Imperva Cloud WAF or WAF Gateway, and its self-managed option helps on hybrid estates. Imperva is now part of Thales, so check the roadmap and support model after that move.
