About

Cybersixgill (formerly 'Sixgill') is an Israeli B2B cyber intelligence company that continuously collects and exposes the earliest possible indications of risk, moments after they surface on the clear, deep, and dark web. Their proprietary algorithms extract data from a wide range of sources, including limited-access deep and dark web forums, underground markets, invite-only messaging groups, code repositories, paste sites, and clear web platforms. The company's solutions are scalable, searchable, and seamlessly integrate into existing security stacks, providing organizations with critical insights to proactively block threats before they become attacks.
