Abstract Security

Composable security operations platform that runs detections on data in motion and lets teams pick their own storage and SIEM back end.

Proof of life. Raised $25M in a round co-led by Cheyenne Ventures and AVP, July 2026

About Abstract Security

Abstract splits the SIEM into parts a team can swap independently: collection, detection, retention, and an AI assistant for triage and investigation.

Its pipeline normalizes and routes logs in OCSF, ECS, or CIM schemas, and runs detection rules while data is still streaming, before it lands in storage.

That lets a security operations team keep Splunk, Sentinel, Google SecOps, or a cheaper tier as the destination without rewriting content.

The company was founded in 2023 by veterans of ArcSight, Mandiant, and Palo Alto Networks, and reports nearly $50 million raised in total.
