The deal follows Celerity’s acquisition of Chilli IT in May 2024, and takes the combined business turnover to more than £50 million and a team of 94.
2 July 2025
UK-based IT services provider Celerity has acquired Silverstring Limited, to add strength and differentiation to its managed services portfolio.
Founded in 2002, Celerity has established itself as a market leader in delivering advanced IT services, with an emphasis on cybersecurity and highly available hybrid-cloud systems. This acquisition brings Silverstring’s deep expertise in data protection and cyber recovery assurance to the Celerity family. Combining these complementary strengths will create a truly unique service provider, with the ability to help customers tackle pressing challenges around operational resilience.
Importantly, the agreement also cements a long-term relationship between Celerity and Silverstring owner Predatar, developer of the innovative recovery assurance technology platform. As part of the deal, Celerity will become a preferred Predatar Apex partner for the UK market.
Predatar Ltd will become a separate entity under the continued leadership of Silverstring’s Founder and former-CEO, Alistair Mackenzie. The deal will enable Predatar to accelerate innovation and growth – strengthening its position as an innovation leader in the market.
“The purpose of this deal is clear. Together, we are creating a cyber resiliency powerhouse, with the skills, expertise and technology to close the gap that currently exists between cybersecurity and data storage infrastructure.”

The transaction follows Celerity’s acquisition of Chilli IT in May 2024. It will take the combined business turnover to more than £50 million and a team of 94.
Speaking about the deal, Celerity’s CEO, Craig Aston, said: “Silverstring is an important acquisition for us, as we’re aiming to boost our capabilities in cyber-secure data protection. Our customers look to us to realise their data’s potential and protect them in an ever-changing environment. We’re looking forward to bringing additional expertise and technology, so we can continue to provide genuinely market-leading expertise and underpin our growth strategy.”
In 2021, Celerity attracted a £15 million investment from BGF.
Harry Jones, Partner at BGF, commented: “Celerity has demonstrated impressive growth since our investment, and this deal represents an important milestone for the business, adding both depth and expertise to the company’s proposition. Moving forward, we’ll continue to look for complementary acquisitions that will drive more innovation and value, for both clients and partners.”
