ArcSight

ArcSight is an enterprise security information and event management (SIEM) platform, now part of OpenText Cybersecurity (formerly Micro Focus, and HP before that). The ArcSight family centers on Enterprise Security Manager (ESM) for real-time correlation and threat detection, alongside Logger for log management and compliance, SmartConnectors for data collection and normalization, Intelligence for behavioral analytics, and Recon for search and investigation. ArcSight was an early Kleiner Perkins portfolio company. It exposes REST and web-services APIs (ESM client services, Logger Web Services, and SCIM user provisioning) primarily to on-premises and SaaS customer deployments rather than as a public developer platform.

ArcSight is profiled on the APIs.io network. Tagged areas include Company, Security, SIEM, Cybersecurity, and Threat Detection.

ArcSight’s developer surface includes documentation, support, and 2 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/arcsight: open an issue to ask a question, or submit a pull request to add artifacts.
