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.

The company's flagship product is the Cybersixgill Threat Intelligence Platform, which delivers automated, contextual intelligence feeds. Cybersixgill also offers an Investigative Portal that allows analysts to conduct manual deep and dark web investigations, and a DVE (Dynamic Vulnerability Exploit) Intelligence product that prioritizes CVEs based on observed criminal discussion and exploitation intent rather than static CVSS scores alone — a differentiator the company has highlighted publicly.

Cybersixgill competes in the threat intelligence market alongside companies such as Recorded Future, Flashpoint, and Intel 471. The distinguishing claim is the depth and automation of dark web collection, particularly access to invitation-only forums that competitors may not index. Detailed public information on market share, analyst rankings, or named customer wins is limited.
