## Our take

What our shortlists say about each one.

### [Imperva Web Application Firewall (WAF)](https://cybersectools.com/tools/imperva-web-application-firewall-waf)

Best for: Regulated teams wanting managed rules, such as banks

Its place here comes from choice: a cloud service, a gateway for older on-premises apps and an elastic option for modern ones, all in one product. The audit logging maps to PCI DSS and GDPR work, which helps if you answer to regulators. Decide which option each app needs, because running gateways in your own data center is a different job from using a cloud service.

### [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.
