VMware acquired the assets of E8 Security, a user and entity behavior analytics company, for an undisclosed amount. The virtualization giant said it will add E8’s security and analytics technology to its digital workspace platform.

Founded in 2014, the startup raised $21.8 million in three funding rounds. Its security platform uses machine learning to detect anomalies and suspicious behavior as well as correlate data from different sources. This reduces “alert fatigue” and helps customers detect actual threats faster, wrote E8 Security CEO Matt Jones in a blog.

“By combining our technology with the insights, app analytics, and powerful automation capabilities of Workspace One, VMware customers will be able to benefit from a simplified way to leverage data from multiple security solutions and provide behavior-based threat detection and risk analysis,” Jones wrote. In addition to its technology, the company’s security team will join VMware as well, he added.

Side note: E8 gets its name from the Lie group in mathematics. The shape “could describe a dynamic and complex system at the tiniest scales” and the company applies “multi-dimensional modeling, graph analysis, and machine learning to address the complexities of cybersecurity so security organizations can scale efficiently and effectively,” according to its website.

Last week VMware updated its digital workspace platform. Workspace One can now integrate users, apps, networks, and endpoint data. It also combines data and analytics from the platform with a new security partner network to provide automated security.

“By adding E8 Security’s user and entity behavior analytics capabilities to insights from VMware Workspace ONE Intelligence, our customers will be able to streamline management, remediation, and automation to improve the employee experience and the security of their digital workspace,” wrote Sumit Dhawan, SVP and general manager of VMware’s end-user computing business, in a blog about the acquisition.

This is VMware’s second security company purchase so far this year. VMware last month acquired CloudCoreo, a public cloud security startup. A spokesperson said VMware will offer CloudCoreo’s security platform as a standalone service.

Both acquisitions show that VMware is getting serious about adding to its security arsenal — a key focus area for the vendor over the past six months.

Last August, at its annual event in Las Vegas, VMware launched its first pure-play security product, AppDefense, which monitors applications running in the cloud and in on-premises data centers for abnormal behavior. And in December, the company announced new cloud-based security software, co-developed with Carbon Black, which automates threat detection and remediation.
