BitSight

Bitsight is a global cyber risk intelligence platform that combines security ratings, external attack surface management (EASM), third-party risk management (TPRM), and cyber threat intelligence (CTI) in a single data model. Its outside-in, agentless monitoring produces continuously updated security ratings validated against real-world breach likelihood, powering vendor risk workflows, insurance underwriting, and capital-markets portfolio oversight for more than 3,500 organizations across 60+ countries. Bitsight exposes a RESTful HTTP API at api.bitsighttech.com (companies, portfolios, ratings, findings, alerts, and CTI) authenticated with an API token over HTTP Basic, documented in the Bitsight Knowledge Base and an interactive Stoplight reference.

BitSight publishes 1 API on the APIs.io network. Tagged areas include Company, Security, Cyber Risk, Security Ratings, and Third-Party Risk Management.

BitSight’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, authentication, and 16 more developer resources.
