Carbon Black (formerly Bit9 and Bit9 + Carbon Black) is a cybersecurity company based in Waltham, Massachusetts.[1] The company develops cloud-native endpoint security software that is designed to detect malicious behavior and to help prevent malicious files from attacking an organization.[2] The company leverages technology known as the Predictive Security Cloud (PSC), a big data and analytics cloud platform that analyzes customers’ unfiltered data for threats.[3]

The company has approximately 100 partners.[4] It has over 5,600 customers including approximately one-third of the Fortune 100.[5]

In October 2019, the company was acquired by VMware.


Carbon Black was founded as Bit9 in 2002 by Todd Brennan, Allen Hillery, and John Hanratty.[6][7] The company's first CEO was George Kassabgi.[8] The current CEO, Patrick Morley, was formerly the chief operating officer of Corel. He took over the position in 2007.[9]

In 2013, the company's network was broken into by malicious actors who copied a private signing key for a certificate and used it to sign malware.[10]

In February 2014, Bit9 acquired start-up security firm Carbon Black.[11][12] At the time of the acquisition, the company also raised $38.25 million in Series E funding, bringing Bit9’s total venture capital raised to approximately $120 million.[13] The company acquired Objective Logistics in June 2015.[14] In August 2015, the company announced that it had acquired data analytics firm Visitrend and would open a technology development center in downtown Boston.[15] A month later, the company announced it would partner with SecureWorks, Ernst & Young, Kroll, Trustwave, and Rapid7 to provide managed security and incident response services.[16][17]

The company changed its name to Carbon Black on February 1, 2016, after being known as "Bit9 + Carbon Black" for approximately two years.[18]

In July 2016, Carbon Black announced it had acquired next-generation antivirus software provider Confer for an undisclosed sum. Prior to the deal, Confer had raised $25 million in venture funding and had more than 50 employees. According to The Wall Street Journal, the deal was valued at $100 million.[19]

On May 4, 2018, the company joined public markets, listing as "CBLK" on the Nasdaq exchange. As part of its initial public offering (IPO), Carbon Black raised approximately $152 million at a valuation of $1.25 billion.[20] Prior to its IPO, the firm had raised $190M from investors including Kleiner Perkins, Highland Capital, Sequoia, Accomplice, and Blackstone.[21][22]

In October 2019, the company was acquired by VMware.[23][24][25]
