Bromium

Aviation · Sunnyvale, United States · Founded 2010

Bromium Inc. operated as a specialized endpoint security firm, leveraging virtualization technology to provide robust protection against malware and other cyber threats. Founded in 2010 by Gaurav Banga, Simon Crosby, and Ian Pratt, the company established its headquarters in Cupertino, California. The founding team brought extensive experience from the virtualization and security sectors; Pratt and Crosby were key figures at XenSource, the company behind the Xen hypervisor, which was acquired by Citrix, while Banga had a background in founding and leading tech companies. The company's core business centered on its proprietary micro-virtualization technology. This approach automatically isolated individual user tasks—such as opening a web browser tab, an email attachment, or a downloaded file—within a lightweight, hardware-enforced micro-virtual machine (micro-VM). Each micro-VM acted as a disposable container, so if a task initiated malicious code, the threat would be contained within that isolated environment and eliminated when the task was closed, preventing any damage to the host computer or the network. This method provided proactive protection against both known and unknown threats, including zero-day attacks, without relying on traditional signature-based detection. Bromium's primary product, initially launched as vSentry in 2012, was geared towards enterprise clients seeking to fortify their endpoint security and reduce the attack surface. Notable early customers included the New York Stock Exchange and ADP. Bromium's business model was based on selling its security software to large organizations. Over its lifespan as an independent entity, the company secured significant venture capital funding, raising approximately $116 million across four rounds from investors including Andreessen Horowitz, Lightspeed Venture Partners, and Intel Capital. A pivotal partnership was formed with HP in 2017, which began licensing Bromium's technology for its Sure Click security feature in commercial PCs. This collaboration culminated in HP's acquisition of Bromium in September 2019 for an undisclosed amount. Following the acquisition, Bromium's technology and team were integrated into HP's broader security platform, becoming a foundational component of what is now known as HP Wolf Security.
