Growth capital investor BGF is to exit London-based cybersecurity company Garrison Technology.

The business has been acquired by US cybersecurity firm Everfox. 

The transaction is subject to regulatory review and customary closing conditions and is expected to close this summer.

As part of the deal, BGF will re-invest into Everfox and continue to back the company as a minority shareholder. 

Garrison Technology was founded in 2014 by Dave Garfield and Henry Harrison. Previously at BAE Systems, the duo joined forces to create robust, patented cyber security tools for government and military functions in the UK and North America.

BGF partnered with Garrison Technology in 2017, providing £8.5 million across two successive funding rounds to support the business as it scaled its operations.

Over the last seven years, Garrison has demonstrated significant growth in the provision of its core cyber security solutions in the UK and across the US and Canada, with sales reaching $20 million in the year to March 2024.

“We created Garrison to develop nation-state level security technologies that enable the most sensitive government missions to operate efficiently in a digital world, and to then extend the availability of these solutions out to critical infrastructure and enterprise customers,” said CEO Garfield.

“BGF has been a supportive partner during an important period of growth providing significant value add support as we scaled our operations into key markets such as the US. 

“Looking to the future, Everfox and Garrison share a similar mission and we are confident the combination of our complementary hardsec solutions with Everfox’s portfolio will accelerate the delivery of high-assurance security that can really make a difference for our customers.”

Alex Snodgrass, investor at BGF, said: “We are proud to have supported Garrison Technology through a seven-year period of growth.

“During this time, we have supported the business to deliver key milestones such as establishing itself in the US with a clear plan for further growth. Following this latest investment, Garrison will continue to establish itself as one of the leading providers of cyber security services and tools on a global scale. 

“We look forward to continuing our support for the business as a minority investor alongside Everfox.”
