Securonix Unified Defense SIEM: pricing, ownership, MITRE coverage
Byline: Oliver Wakefield-Smith, Founder, Digital Signet.
Securonix Unified Defense SIEM[14] sells on per-identity pricing. The Snowflake-native architecture[23] decouples the data lake from the SIEM vendor for portability.
Securonix EON
EON agentic AI launched 2025 with autonomous triage. The per-identity model means EON-assisted analyst-hours do not change the bill the same way an ingest-priced SIEM would.
M&A stability
Vista Equity Partners has owned Securonix since 2022. The PE-owned posture is the stability story; pricing remains quote-only despite buyer pressure to publish.
