Cybersecurity Startup Takes in $9.5M

Newport Beach startup Obsidian Security raised $9.5 million in Series A funding led by Silicon Valley venture capitalist Greylock Partners.

The software maker will use the cash to boost engineering and development for a product offering that fuses security, artificial intelligence and hybrid-cloud technology.

“We’re sort of just beginning the process of really hiring and building the company,” said Glenn Chisholm, who co-founded the company with fellow security experts Ben Johnson and Matt Wolff.

Chisholm is former chief technology officer at Irvine-based security software maker Cylance Inc. and chief information security officer at Telstra, Australia’s largest telecom. Wolff is Cylance’s former chief data scientist.

Johnson is co-founder and former chief technology officer of Carbon Black in Cambridge, Mass.
