Verdict by buyer type
Which of the two fits each kind of team.
| Buyer | Verdict |
|---|---|
| Google SecOps estate | Google Security Operations is the better fit: it runs the estate natively, with YARA-L rules, a Rules API and a Content Manager CLI; Panther documents no Google SecOps path. |
| a team starting from scratch with Sigma | Panther is the better fit: it converts Sigma with sigma-cli into Python or Simple detections and tests them in CI; Google Security Operations documents YARA-L and no Sigma path. |
| Microsoft Sentinel estate | Neither Google Security Operations nor Panther documents a path for this buyer, so it does not separate them. |
When to pick each
Google Security Operations: Pick Google Security Operations when rule health is the deciding need: it shows rule errors, latency metrics and rule quotas on a Rule Observability dashboard. It also leads on versioning and lifecycle.
Panther: Pick Panther when rule languages is the deciding need: it writes detections in Python and converts Sigma rules with sigma-cli.
