Coalition

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.

Coalition publishes 1 API on the APIs.io network: Cve API. Tagged areas include Cyber Insurance, Insurance, Insurtech, Risk Management, and Cybersecurity.

The Coalition catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Coalition’s developer surface includes engineering blog, YouTube channel, and 24 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Insurance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/coalition-inc: open an issue to ask a question, or submit a pull request to add artifacts.
