## Our take

What our shortlists say about the one we picked.

### [Black Duck Polaris Platform](https://cybersectools.com/tools/black-duck-polaris-platform)

Best for: Teams managing open-source and license risk

Black Duck Polaris belongs here for companies whose biggest risk sits in third-party and open-source code, where license rules matter as much as vulnerabilities. That suits firms that ship software to others or must answer for the licenses in their code. Plan setup time and skilled people for the first rollout, because event-based scans across many repositories need care to set up.
