## Our take

What our shortlists say about each one.

### [Rapid7 InsightAppSec](https://cybersectools.com/tools/rapid7-insightappsec)

Best for: Teams wanting quick setup and a clear dashboard

It is on this list because Attack Replay lets developers check a finding and its fix themselves, which keeps security out of the middle of every ticket. It fits teams of any size that need compliance reports, and the on-premises engine helps if some apps sit on closed networks. It is built on Rapid7's Insight platform, so ask what you gain if you do not use that platform today.

### [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.
