Verdict by buyer type
Which of the two fits each kind of team.
| Buyer | Verdict |
|---|---|
| Splunk estate | Splunk Enterprise Security (Cisco) is the better fit: it runs the estate natively, with SPL content built and tested by contentctl; Sekoia documents no Splunk path. |
| a team starting from scratch with Sigma | Sekoia is the better fit: it runs native Sigma YAML, correlation rules included, but documents no CI workflow; Splunk Enterprise Security (Cisco) documents SPL content and no Sigma path. |
| Microsoft Sentinel estate | Neither Sekoia nor Splunk Enterprise Security (Cisco) documents a path for this buyer, so it does not separate them. |
When to pick each
Sekoia.io: Pick Sekoia when rule languages is the deciding need: it runs native Sigma YAML, including event_count, value_count and temporal correlation, alongside its own SOL queries.
Splunk Enterprise Security (Cisco): Pick Splunk Enterprise Security (Cisco) when testing is the deciding need: it runs contentctl test, which replays Splunk Attack Data through detections in a real Splunk instance.
