Our take
What our shortlists say about the one we picked.
- 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.
