  Coalition is a San Francisco–headquartered cyber insurance and active risk
  management provider founded in 2017 by Joshua Motta (CEO) and John Hering.
  Coalition pairs commercial insurance lines — Cyber, Technology Errors &
  Omissions, Executive Risks (D&O, EPL, Fiduciary, Crime), Miscellaneous
  Professional Liability, and AI coverage — with a continuous attack-surface
  monitoring and incident-response platform (Coalition Control, Wirespeed
  ADR, Coalition Incident Response, Security Awareness Training). The
  company's underwriting engine is exposed to brokers and distribution
  partners through the Coalition Active Insurance API, a RESTful surface
  that supports rate, quote, bind, document generation, renewals, and
  webhook events across the United States and Canada, with executive risks
  APIs and additional product lines added over time. Coalition also
  publishes a public Exploit Scoring System (ESS) API at
  ess-api.coalitioninc.com that exposes CVE detail, ESS/EPSS/CVSS scoring,
  exploit references (ExploitDB, Metasploit), GitHub repository signals,
  and Twitter mention timelines for over 200,000 vulnerabilities.
  Coalition is backed by Allianz X, Valor Equity Partners, Ribbit Capital,
  Mitsui Sumitomo, Kinetic Partners and other strategic insurers
  (Allianz, Arch, Ascot, Zurich, Swiss Re, Lloyd's syndicates); it raised
  a $250M Series F in 2022 at a $5B valuation. The Active Insurance API
  is partner-gated (no public OpenAPI), but the ESS API is fully public
  with OpenAPI 3.1, an interactive docs UI, and ReDoc.
