Material Security

Material Security is a cloud workspace security platform for Google Workspace and Microsoft 365. It connects via API (not an inline gateway) to give security teams unified detection and response across email, accounts and identity, and sensitive data — protecting against advanced email threats and phishing, preventing risky file sharing while automatically classifying sensitive data, and detecting account takeover and identity threats. Material is a private company backed by Andreessen Horowitz (a16z) and Amplify Partners.

Material Security is profiled on the APIs.io network. Tagged areas include Company, Security, Email Security, Cloud Workspace Security, and Data Security.

Material Security’s developer surface includes pricing, engineering blog, and 9 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

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/material-security: open an issue to ask a question, or submit a pull request to add artifacts.
