## Our take

What our shortlists say about the one we picked.

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

Best for: Teams wanting inline API blocking without specifications

Wallarm earns its place because it can start blocking before your APIs are documented, which helps when your specs lag behind the code. It runs hybrid, so you can put the filtering where your traffic is. Before you choose it, test its blocking modes on your busiest APIs, because a wrong block there lands on real users.
