- 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.

- Fastly API Security
Best for: Fastly customers protecting APIs on the edge
It is on the list because discovery and blocking happen on the Fastly edge where your API traffic already flows, and it sends alerts to Slack, Jira, PagerDuty and Datadog. If your APIs are not behind Fastly, or most of your risk sits in internal and partner APIs, its edge view will see less of it, so weigh that first.
