## Our take

What our shortlists say about the one we picked.

### [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.
