Verdict by buyer type

Which of the two fits each kind of team.

BuyerVerdict
Microsoft Sentinel estateSigma and pySigma is the better fit: they convert Sigma to KQL through its Kusto backend, listed as Stable; SOC Prime claims Sigma translation to dozens of languages and names none.
Elastic estateSigma and pySigma is the better fit: they convert Sigma to Lucene, ES|QL and EQL through its Elasticsearch backend; SOC Prime claims Sigma translation to dozens of languages and names none.
Splunk estateSigma and pySigma is the better fit: they convert Sigma to SPL through its Splunk backend; SOC Prime claims Sigma translation to dozens of languages and names none.
Google SecOps estateBoth document a route: Sigma and pySigma have a Google SecOps backend that its backend list marks as Development, and SOC Prime claims Sigma translation to dozens of languages and names none, so the difference above decides.
a team starting from scratch with SigmaSigma and pySigma is the better fit: they are the format itself and converts it to Splunk, Kusto and Elasticsearch targets, with no runtime, tests or health checks; SOC Prime claims Sigma conversion to dozens of targets that its pages do not name.

When to pick each

Sigma and pySigma: Pick Sigma and pySigma when rule languages is the deciding need: they convert one rule to Splunk, Kusto and Elasticsearch (Lucene, ES|QL, EQL) backends through installable plugins. They also lead on versioning and lifecycle.

SOC Prime: Pick SOC Prime when testing is the deciding need: it says Uncoder AI validates translated rules and describes no replay or unit test method.
