Are out-of-state takeovers changing the nature of San Antonio's nascent cyber industry? FacebookTwitterEmail A flurry of out-of-state corporate takeovers is changing Cyber City USA. Denim Group, one of San Antonio’s largest homegrown cybersecurity firms, announced June 1 it had been acquired by Colorado-based CoalFire. The businesses didn’t disclose the details, and it’s too early to tell what it means for Denim’s employees and facilities. It was the third San Antonio cyber buyout since mid-2020. Last July, Minnesota-based HelpSystems bought Globalscape and took the data exchange solutions company private in a roughly $219 million deal. Then, in February, HelpSystems gobbled up Digital Defense, another of the city’s old guard cyber heavyweights, for an undisclosed amount. At the time, corporate execs said they had no plans to make cuts or move anyone from Texas.
