LevelBlue

LevelBlue is a pure-play managed security service provider (MSSP), formed from AT&T Cybersecurity and the AlienVault platform it acquired, delivering managed detection and response, managed cloud and network security, incident readiness and response, cyber advisory, exposure management and email security, backed by SpiderLabs threat intelligence. Its developer surface is the USM Anywhere v2.0 REST API — a per-tenant, OAuth 2.0 client-credentials API over alarms and normalized security events, with HAL pagination and a webhook connector for pushing third-party events into the platform — alongside the LevelBlue Open Threat Exchange (OTX) DirectConnect API for community threat intelligence.

LevelBlue publishes 3 APIs on the APIs.io network: Alarms API, Events API, and OAuth API. Tagged areas include Company, Enterprise, Cybersecurity, Security, and Threat Intelligence.

The LevelBlue catalog on APIs.io includes 1 event-driven AsyncAPI specification.

LevelBlue’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, authentication, and 26 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
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/levelblue: open an issue to ask a question, or submit a pull request to add artifacts.
