Our story began in 2009 with the founding of Vacta (meaning “a shift on watch” in old Norse) by Adarma’s CTO Nathan Dornbrook.
By October of 2012, the start-up had grown to a team of twelve people including Adarma’s CEO David Calder, all passionate about providing security skills to their customers. At this point, following investment from the ECS Group, Vacta became ECS Security.
Our mission was then as it is today:
- To provide security solutions that enable our customers to succeed in their core business and maximise the benefit of digitalisation.
- To secure our customers through our unique approach, methods, and shared passion, allowing them to do what they do best.
- To align with our customers’ missions in true partnership, helping them understand and address the threats they face.
Between 2012 and 2018, ECS Security’s team grew to over two hundred people, carrying on our mission to provide high-quality security solutions to customers through professional services, managed services and best-of-breed technology partnerships. Our customers include household names in the Finance and Retail sectors, who rely on us as a trusted and dependable partner to support them in delivering threat management solutions.
In 2019 the ECS Security management team performed a management buyout and rebranded to Adarma, now positioned as an independent autonomous company to further accelerate the growth enjoyed in recent years.
Adarma is now one of the leading independent security companies in the UK, with a client base of FTSE 350 customers, several key strategic technology partners, and a rapidly growing, highly experienced team of over 250 staff. We were Splunk partner of the year 2019 and continue to deliver sustainable, quality assured security services.
