Cybersixgill

Founded in 2014 by Avi Kasztan and Elad Lavi, Cybersixgill is a cybersecurity firm that specializes in threat intelligence. The company, headquartered in Tel Aviv, Israel, was established to provide automated monitoring of the deep and dark web to preemptively identify cyber threats. From its early days, Cybersixgill demonstrated its potential by joining a Citibank accelerator program shortly after its inception. A significant milestone in the company's history was its acquisition by the American cyber risk management company BitSight in November 2024 for a reported $115 million. Prior to the acquisition, the company had successfully raised $56 million in funding over several rounds, including a $35 million Series B round in March 2022.

Cybersixgill's core business revolves around a Software-as-a-Service (SaaS) platform that provides real-time, actionable threat intelligence. The company continuously and automatically collects vast amounts of data from the clear, deep, and dark web, including limited-access forums, underground markets, and private messaging groups. This data is then processed and analyzed using proprietary algorithms and machine learning to identify potential threats such as data leaks, phishing schemes, and malware. The primary revenue stream is a subscription-based model, offering tiered plans to cater to different client needs. Its client base is diverse, serving global enterprises, financial institutions, government agencies, and managed security service providers (MSSPs).

The company's product portfolio is designed to provide comprehensive threat visibility. The main offering is its Cyber Threat Intelligence platform, which grants users access to its extensive data lake. Another key product is the DVE (Dynamic Vulnerability Exploit) Intelligence solution, which helps organizations prioritize vulnerabilities based on real-world threat actor intent, rather than just technical severity. Recently, Cybersixgill introduced an Attack Surface Management product that combines external asset discovery with its threat intelligence capabilities to identify risks across an organization's network. The firm also leverages generative AI in its Cybersixgill IQ product to translate complex threat data into accessible insights and reports. This allows security teams to proactively block threats and enhance their overall cyber resilience before an attack occurs.
