## Our take

What our shortlists say about the one we picked.

### [Splunk Enterprise Security](https://cybersectools.com/tools/splunk-enterprise-security)

Best for: Large SOCs that want to search every log in one place

Splunk is on the list as the search-first SIEM, which suits mid-market and enterprise SOCs that want to query any log and build their own detections. Federated search means you do not have to move every log into one store to use it. Splunk is part of Cisco and its company momentum has stalled, so ask how the product will develop inside Cisco.
