CyberGRX

CyberGRX is a third-party cyber risk management platform — the Global Risk Exchange (GRX) — that helps organizations assess, monitor, and reduce risk across their vendor and supplier ecosystem. It combines a shared library of standardized vendor risk assessments with analytics for inherent and residual risk, control gaps, and findings. CyberGRX was acquired by ProcessUnity in 2023 and is now delivered as the ProcessUnity Global Risk Exchange. It exposes a versioned REST API (v1, bulk-v1, v2) authenticated with an account API token passed in the Authorization header, including a Bulk API that returns an entire third-party ecosystem — residual risk, control scores, and findings — in a single request, plus first-party Python examples and Go/Splunk connectors.

CyberGRX publishes 1 API on the APIs.io network. Tagged areas include Company, Cybersecurity, Third Party Risk, Vendor Risk Management, and Risk Management.

CyberGRX’s developer surface includes API reference, documentation, getting-started guide, support, engineering blog, authentication, sandbox, and 9 more developer resources.
