A former vice-president from US giant Cisco has been appointed the new chief executive of Adarma, the Edinburgh-based cyber security business.

John Maynard takes up the post at the end of this month, with current chief executive David Calder taking on the role of chief product officer. In his new position, Mr Calder will help drive the overall strategy and services roadmap for Adarma, which in October posted a record 27 per cent increase in revenues to £41 million.

Mr Maynard was previously vice-president of the global security specialists group at Cisco. Prior to that, he was based in San Francisco and had a dual-role at DXC Technology as chief operating officer and vice president of product management for Cybersecurity.

Mr Maynard also held cyber leadership positions at Hewlett Packard for more than ten years, was responsible for the acquisition of Vistorm in the UK and led the cyber security business in Asia-Pacific and Japan based out of Singapore.

The appointment comes as Adarma seeks to expand its service offerings and drive international growth across the UK, US and Europe. It follows the completion of a management buy-out at the end of last year backed by mid-market private equity house Livingbridge.

During his seven years as chief executive, Mr Calder oversaw the expansion of the company from 12 to more than 250 people, with revenues increasing from £1.5m.

“John is a leading light in the security industry and I have no doubt that his experience in driving rapid international growth will significantly benefit Adarma’s future," Mr Calder said.

"With the global pandemic accelerating conversations about the need for comprehensive and proactive security strategies, there is a huge opportunity to grow our customer base and deliver a wider range of services to help businesses of all sizes increase their cyber resilience."

Mr Maynard added: “I truly believe in Adarma’s potential for growth and look forward to working with David and the wider leadership team to take the company to its next phase of development.

“The vision and talent of the team at Adarma has already led to an extensive list of successes in recent years, including consistently increasing revenues by providing proactive security threat management for some of the UK’s most well-known brands.”
