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.
