SentinelOne to acquire Attivo Networks for $616 million

Cybersecurity firm SentinelOne announced today it will acquire identity security and lateral movement protection company Attivo Networks for $616.5 million in what will be one of the largest cybersecurity deals in the last year.

The multimillion-dollar move is expected to enhance SentinelOne’s strategy for helping enterprises adopt the zero-trust framework — a model that has gained broad acceptance in recent years by government and corporate organizations for its focus on assuming that users and devices on a network must be continuously verified. An executive order signed by President Biden in May emphasized zero-trust principles and put pressure on federal organizations to transition their security strategy. 

Attivo, whose investors include Bain Capital Ventures, ForgePoint Capital, and Omidyar Technology Ventures — the Silicon Valley investment firm funded by eBay founder Pierre Omidyar — specializes in protecting identities, credentials, and high-value assets across endpoints. The company has over 200 employees and more than 450 customers, according to a fact sheet published by the firm this year.

The cash-and-stock deal is expected to conclude in the fiscal second quarter, and is contingent on supervisory proceedings, the company said.

“The acquisition of Attivo Networks continues our commitment to defining and delivering autonomous XDR,” said SentinelOne CEO Tomer Weingarten, referring to extended detection and response technology. “Identity fuses together all enterprise assets, and I see identity threat detection and response as an integral part of our XDR vision.”
