CloudPassage was founded by Carson Sweet, Talli Somekh, and Vitaliy Geraymovych in 2010. ^{[6] [7]} The company used cloud computing and big data analytics to implement security monitoring and control in a platform called Halo. ^[8] CloudPassage spent a year in stealth developing the Halo technology, coming out of stealth mode to a closed beta in January 2011. In June 2012, the company launched the commercial product that included configuration security monitoring, network microsegmentation, and two-factor authentication for privileged access management. ^[9] By 2013, CloudPassage expanded Halo to support large enterprises with advanced security and compliance requirements with a product called Halo Enterprise. ^{[10] [11]}

The first round of venture funding for the company raised $6.5 million. ^[7] In April 2012, CloudPassage raised $14 million. ^[12] The financing round was led by Tenaya Capital. ^[12] In February 2014, CloudPassage announced that it had raised $25.5 million in funding led by Shasta Ventures. ^{[13] [14]} In total, the company has invested over $30 million in its technology and raised approximately $88 million in capital.

The CloudPassage platform provides cloud workload security ^[15] and compliance for systems hosted in public or private cloud infrastructure environments, including hybrid cloud and multi-cloud workload hosting models. ^[16] The flagship product the company offers is called Halo. ^{[17] [18]} Halo secures virtual servers in public, private, and hybrid cloud infrastructures and provides file integrity monitoring (FIM) ^{[18] [19]} while also administering firewall automation, vulnerability monitoring, network access control, security event alerting, and assessment. ^{[20] [16] [21]} The Halo platform also provides security applications such as privileged access management, software vulnerability scanning, multifactor authentication, and log-based IDS. ^[21]

In December 2013, CloudPassage set up six servers with Microsoft Windows and Linux operating systems and combinations of popular programs and invited hackers to attempt to hack into the servers. ^[22] The top prize was $5,000 and the winning hacker was a novice that completed the task in four hours. ^[22] CloudPassage programmed the servers to use basic default security settings to show how vulnerable cloud computing programs can be to security threats. ^[22]
