One of San Antonio’s leading cybersecurity firms, the Denim Group, has been acquired by another cybersecurity firm based in Colorado for an undisclosed amount of money.

Coalfire, which has multiple offices across the country as well as in England, announced the deal Tuesday. The company’s release said the acquisition – and the use of Denim Group’s application security platform – would allow it to address security breaches “40 percent” faster.

Together, the combined firms now serve over 1,800 clients, including cloud service giants Amazon, Google, and Microsoft, as well as half of the largest U.S. banks, leading government agencies, and the largest health care companies, according to Coalfire.

“This is a big deal,” said Denim Group principal John Dickson.

Denim Group – once among the country’s fastest-growing companies – had reached the point where it needed to expand significantly its reach to meet client needs, he said, giving the example of servicing a client in London.

The company employs roughly 100 people, Dickson said, adding that he hopes to hire more graduates from the universities in San Antonio.

Beyond scaling Denim Group’s capacity, Dickson said the deal was attractive because of the possibilities for cross-pollination. He said that compared to Denim Group, Coalfire has a bigger footprint with the big three cloud providers.

“We’ve got our work cut out for us,” he said. “And we’ve got to do more to keep ahead of a threat that continues to metastasize.”

A series of high-profile hacks has gripped the country in recent months, including the SolarWinds hacks and the Colonial Pipeline hack.

Denim Group, founded in 2001, will remain in San Antonio and under the leadership of principals Dickson, Dan Cornell, and Sheridan Chambers.
