## Our take

What our shortlists say about the one we picked.

### [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.
