What our shortlists say about the one we picked.
Best for: API-heavy teams that want web, API and bot protection in one engine
It earns a place because one engine covers web attacks, API attacks and bot abuse, so you do not run a WAF, an API gateway and a bot product side by side. If you run the filtering nodes yourself, ask how much upkeep they need, and test blocking on your own API traffic before you switch it on.
