Versive

Versive was a Seattle-based artificial-intelligence and machine-learning cybersecurity company (originally founded as Context Relevant) whose flagship product, the Versive Security Engine (VSE), applied machine learning to network and security telemetry to automatically surface adversary campaigns and in-progress breaches for security operations teams. Backed by Bloomberg Beta and other investors, Versive was acquired by managed-detection-and-response provider eSentire in October 2018, after which its technology was folded into eSentire's MDR platform and the independent Versive website (versive.com) was retired. This profile is retained in the API Evangelist network as a portfolio lead; the enrichment pipeline found no live, independent Versive developer or API surface to harvest.

Versive is profiled on the APIs.io network. Tagged areas include Company, Security, Cybersecurity, Artificial Intelligence, and Machine-Learning.

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