About Bitsight

Bitsight is a cybersecurity ratings company, providing objective, verifiable, and actionable security performance data. Bitsight's CTI, formerly Cybersixgill, continuously collects and exposes the earliest possible indications of risk produced by threat actors moments after they surface on the clear, deep, and dark web. This data is processed, correlated, and enriched with machine learning techniques to create profiles and patterns of threat actors and their peer networks, delivering critical insight into the nature, source, and context of each threat.

Bitsight's extensive threat intelligence data is consumed through various solution offerings and integrations, each addressing critical customer pain points and use cases. These solutions are scalable, searchable, and seamlessly integrated into existing security stacks, arming teams with critical insights to proactively block threats before they materialize into attacks.
