20 Jun

LONDON, UK – 20th June 2025

We’re incredibly proud to announce that Cyro Cyber has been ranked 6th in Business Leader’s Growth 500, a list celebrating the fastest growing businesses across the UK.

This achievement comes at a time when cyber threats are rising in frequency, scale and sophistication. As attacks grow more complex, the need for robust, proactive defence has never been more critical.

Cyro Cyber is proud to be trusted by some of the UK’s most vital organisations, including leaders in critical national infrastructure, healthcare, finance and beyond. We believe businesses should be free to drive innovation and do what they do best, without being held back by persistent cyber risk. That’s why we help them identify regulatory and operational risk, protect critical systems, and detect and respond to threats across complex, high value environments to protect the systems that keep society running and help organisations defend against the threats of tomorrow.

"We’re honoured to be recognised in this year’s Growth 500," said Shannon Simpson, CEO of Cyro Cyber. "This reflects the urgency of the moment, and the trust placed in us by clients working in some of the highest staked environments. Our team is driven by a deep sense of purpose - to safeguard the technologies and services people rely on every day. This is just the beginning."

We’re grateful to our clients, our partners and our team for helping us reach this point. We’re incredibly proud to be an instrumental part of the fight to build a safer digital future for us all.
