Tenable to acquire external attack surface management vendor

Tenable, the cybersecurity company, has signed an agreement to acquire Bit Discovery, an external attack surface management (EASM) vendor.

Under the terms of the agreement, Tenable will acquire Bit Discovery for a total purchase price of $44.5m in cash, subject to customary purchase price adjustments.

Combining Tenable’s cyber exposure solutions with Bit Discovery’s EASM capabilities will provide customers with a differentiated 360-degree view of the modern attack surface – both inside out and outside in – to identify and eliminate areas of known and unknown security risk, a statement said.

After closing, Tenable will leverage the EASM solutions across its entire portfolio – from enterprise vulnerability management (VM) to Nessus, from cloud to operational technology (OT) to identity. Once integrated, customers will have the ability to assess the security posture of their entire attack surface and understand each of these in the context of an attack path which might exist from external systems to critical assets.

“Whatever is visible on the internet is very likely to be the first target and the hardest thing for organisations to continuously see and assess. We believe attack surface management is vital to modern cybersecurity and an integral part of our vulnerability and cyber exposure solutions,” said Glen Pendley, chief technology officer, Tenable. “We are seamlessly combining previously disjointed insights and empowering security practitioners to eliminate blind spots and easily understand their cyber exposure in ways previously not possible.”

“Joining Tenable will give us the ability to instantly reach 40,000 global customers, accelerating our vision in ways that would have otherwise been impossible,” said Jeremiah Grossman, CEO and co-founder, Bit Discovery. “This capability combined with the insights provided by Tenable’s solutions is a compelling chance to change the market.”

Bit Discovery was founded by Grossman and Robert Hansen. Grossman, who also founded WhiteHat Security, has spent approximately 20 years in information security. Hansen previously served as a security pioneer at eBay, where he was responsible for authentication as well as anti-fraud and anti-phishing technologies.

The acquisition is expected to close later in the second quarter of 2022, subject to the satisfaction of customary closing conditions.
