Cybersixgill

Cybersixgill is an Israeli cybersecurity company focused on threat intelligence derived from the deep and dark web. The company collects and analyzes data from closed underground forums, illicit marketplaces, and other covert online sources to provide security teams with early warning of emerging threats, exposed credentials, and threat actor activity.

Cybersixgill's primary offering is a threat intelligence platform that continuously crawls and indexes content from deep web and dark web sources — including closed Telegram channels, paste sites, and underground hacker forums — that are largely inaccessible to conventional security tools. The intended buyers are enterprise security operations centers (SOCs), government agencies, and managed security service providers (MSSPs) that need visibility into threat actor intent and stolen data before it is weaponized. The platform surfaces intelligence such as compromised credentials, planned attacks, and newly disclosed vulnerabilities being discussed in criminal communities.
