Two notable acquisitions were announced in the cybersecurity space today as managed security provider LevelBlue Inc. revealed plans to acquire Cybereason Inc., while healthcare identity and access management firm Imprivata Inc. announced the purchase of Verosint Inc., an identity threat detection and response company.

LevelBlue, which until May 2024 was known as AT&T Cybersecurity, said its acquisition of Cybereason will offer clients and strategic partners immediate value with stronger threat detection, faster response and broader global coverage, from a single, unified security partner.

Founded in 2012, Cybereason offers an automated endpoint detection and response platform that identifies elements of cyberattacks for effective response in real time. The company’s platform detects signature-based and non-signature-based attacks and accelerates incident investigation and response, connecting individual pieces of evidence to form a complete picture of a malicious operation.

Cybereason’s platform draws on an extensive database of threat signatures and collections of technical data on hacking tactics to identify breach attempts that use methods known to the cybersecurity community. The service delivers enhanced investigation of attacks and continuous endpoint visibility via a big-data analytics platform designed to reveal malicious operations.

Earlier this year, Cybereason scrapped a planned merger with managed cybersecurity services provider Trustwave Holdings Inc., which was then followed in July by LevelBlue acquiring Trustwave; ultimately, the companies will be merged, just not the way they originally planned.

Coming into its acquisition, Cybereason had raised $938 million in venture capital funding over 10 rounds, including rounds of $100 million in April 2023 and $120 million in March. Investors in the company include SoftBank Vision Fund LP, Liberty Strategic Capital, Google, Charles River Ventures LP, Spark Capital Management, Irving Investors and Neuberger Berman.

“The addition of Cybereason is a strategic leap forward in our mission to become the most complete cybersecurity partner for our clients and strategic partners,” said Bob McCullen, chief executive of LevelBlue. “By combining Cybereason’s world-class extended detection and response and digital forensics and incident response capabilities with our AI-powered managed detection and response and incident response, we can deliver unified protection that’s proactive, scalable and purpose-built for today’s fast-evolving threats.”

Imprivata said its acquisition is its latest strategic investment in modernizing enterprise access management with solutions that deliver advanced, frictionless and passwordless access for every user type, including frontline staff, knowledge workers and third-party identities, while strengthening security, streamlining compliance and reducing total cost of ownership.

Founded in 2021, Verosint offers identity threat detection and response that is designed to continuously protect enterprise and consumer identities from evolving attacks. The company’s platform ingests signals from identity systems, event logs and behavioral data to build a unified identity graph enriched with external intelligence.

Verosint also automates investigation and response workflows, enabling security teams to act swiftly on critical identity risks. The company’s agentic artificial intelligence agent called Vera can triage threats, suggest or execute remedial actions such as suspending accounts or enforcing multifactor authentication and generate incident reports.

According to data from Tracxn, Verosint had raised $2 million in a single round in October 2024.

Imprivata plans to integrate Verosint’s AI-powered risk engine into its own platform to support a broader vision for delivering what it calls a comprehensive, advanced and passwordless access platform.
