  title: Cybereason Authentication API
  version: 23.x
  description: 'Cybereason EDR/XDR REST API. Exposes Malop investigation, hunting

    via Visual Search, sensor management, isolation rules, custom

    detection rules, reputation lists, threat-intel lookups, malware

    queries, and remediation actions against a Cybereason tenant.


    Best-effort spec derived from publicly indexed Cybereason API

    documentation references (api-doc.cybereason.com URI/endpoints

    pages, docs.cybereason.com 23.2 docs, Cortex XSOAR / Demisto

    Cybereason integration, and the open-source CybereasonAPI

    PowerShell module). Cybereason''s primary API documentation is

    customer/partner-gated; the operational surface modelled here

    matches the publicly described endpoints.


    Authentication is performed via a POST to /login.html which

    returns a JSESSIONID cookie used on subsequent calls. JWT

    authentication is also supported on version 20.1+ deployments.
