San Antonio-based Carbon Black is Acquired by Bit9

Carbon Black, a San Antonio-based cyber security startup, has merged with Waltham, MA-based Bit9.
Carbon Black makes software to deal with detection of hackers on a computer system and response to hackers once an incidence has occurred. Bit9 makes software to prevent those attacks from occurring.
Financial terms of the transaction were not disclosed.
Bit9 also announced that is has raised $38.25 million from Atlas Ventures, Paramount Pictures, .406 Ventures, Highland Capital Partners, Kleiner Perkins Caufield & Byers and Sequoia Capital to fuel its growth. The company, founded in 2005, has raised $121 million to date with the latest financing, according to its Crunchbase profile.
The merged companies will be known as Bit9. Carbon Black CEO Mike Viscuso will move to the Boston area to become the new chief strategy officer at Bit9.
Scott Lundgren, director of engineering, and his team have been working out of offices on the 10th floor of Geekdom. The company has 16 employees.
“Every enterprise endpoint and server is a defenseless blind spot for advanced threats,” Patrick Morley, Bit9 president and CEO, said in a news release. “Traditional defenses such as antivirus can’t detect or stop stealthy attacks orchestrated by malicious actors, or help companies respond to incidents, which has been painfully underlined by the recent high-profile intrusions into leading retailers. The combination of Bit9 and Carbon Black satisfies all of these needs.”
