Headless SIEM
Also known as: Headless Security Operations
A SIEM operating model where structured security work is reachable through approved interfaces beyond the main console, from APIs and reports through to AI clients.
Headless SIEM separates security work from a single user interface. Several kinds of work can be requested through several controlled interfaces.
- Investigations
- Health checks
- Reports
- Detections
- Approved actions
Underneath, the platform still holds the controls.
- Identity
- Scope
- Evidence
- Permissions
- Audit records
That is what separates a headless model from an open API. The term does not mean unrestricted access. A buyer should test whether the same case and evidence remain consistent across interfaces and whether denied actions are enforced and recorded.
