What our shortlists say about the one we picked.

### [Mandiant Threat Defense](https://cybersectools.com/tools/mandiant-threat-defense)

Best for: Google Security Operations customers wanting expert hunting

Mandiant Threat Defense earns a spot because its analysts lead the hunting and investigation, and a case can move straight to Mandiant Incident Response if it grows. It fits mid-market and enterprise teams that use, or plan to use, Google Security Operations, since the service runs there. Ask which containment steps the analysts take themselves and which come back to you as guided remediation.
