Seceon aiSIEM CGuard 2.0 vs Substation: Side-by-Side Comparison (2026)

Seceon aiSIEM CGuard 2.0

Mid-market and enterprise teams managing sprawling Microsoft 365 and multi-cloud identities will find real value in aiSIEM CGuard 2.0 because its AI-driven threat detection focuses on the attacks most SIEMs miss: lateral movement, privilege abuse, and cryptojacking across cloud services rather than just log volume. The 200+ built-in detection rules and automated response actions like OAuth revocation and identity quarantine cut mean time to remediate by handling the tactical work your team can't sustain manually. Skip this if you need deep on-premises infrastructure monitoring or strong forensic-grade incident analysis; CGuard prioritizes detection and immediate mitigation over the investigative depth that legacy incident response workflows demand.

Substation

Security teams building custom detection pipelines on AWS will get immediate value from Substation's event-driven architecture; it routes security data across services and enriches events with APIs without the overhead of commercial SIEM licensing. The free, open-source model (390 GitHub stars) means no vendor lock-in and full control over data formatting and routing logic. Skip this if your team lacks AWS expertise or needs out-of-the-box alerting and dashboards; Substation is a data plumbing tool, not a detection platform.
