## Our take

What our shortlists say about each one.

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

Best for: Imperva WAF customers adding API discovery

Imperva earns a spot because it catches one user reading another user's data as it happens and can block it inline through the WAF you may already run. It suits you best if that WAF is Imperva Cloud WAF or WAF Gateway, and its self-managed option helps on hybrid estates. Imperva is now part of Thales, so check the roadmap and support model after that move.

### [Tenable One Web App Scanning](https://cybersectools.com/tools/tenable-web-app-scanning)

Best for: Teams already using Tenable for vulnerability scanning

It belongs here because it adds web app testing to the Tenable products many teams already use for vulnerability scanning, so web findings sit next to the rest. It fits teams of any size already on Tenable One or Security Center. Its listed integrations are all Tenable products, so if you want a scan on every release, ask how it connects to your CI/CD pipeline and ticketing.
