That fits mid-market and enterprise teams with heavy event volumes. Vista Equity Partners has owned Securonix since 2022, so ask how the ThreatQuotient platform will merge into the main product. From [Best SIEM Solutions for Business](https://cybersectools.com/shortlists/best-siem-solutions), Fall 2026. ### [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.
