On 13th November 2025, OnSecurity was named South West Business of the Year – Investment Category. This win recognises the landmark year for us, following rapid scale, strategic expansion and a bold application of AI across both product and operations.
Investment Fuelling Sector-Leading Growth
A major driver behind OnSecurity’s trajectory has been the £5.5 million investment round with Gresham House Ventures, which has enabled the business to accelerate its long-term vision while scaling sustainably. Since closing the round, we have doubled the headcount in under 12 months, making strategic hires across engineering, operations and commercial leadership.
The impact of this investment has resonated beyond the business community, with OnSecurity’s funding milestone recently cited in the UK Government’s March publication, AI and software cyber security market analysis, which spotlighted only three UK cybersecurity providers for notable investment activity between 2019 and 2024.
“We’re not just growing for growth’s sake,” said Conor O’Neill, CEO and Co-Founder of OnSecurity. “This investment has allowed us to scale intelligently, strengthening our team, advancing our technology, and keeping our clients ahead of emerging threats. This award is a reflection of that strategy in action.”
A New Generation of Cybersecurity: AI-Augmented, Human-Led
Innovation continues to sit at the heart of OnSecurity’s offering. This year, as we launched our AI-augmented penetration testing capabilities, we blended advanced automation with human expertise to deliver faster, more comprehensive, and more actionable security insights.
Unlike traditional pentest providers reliant on slow, manual processes, our hybrid model enables testers to identify findings and report them in real time, allowing clients to remediate and retest within minutes, not days.
Beyond the platform, we are embedding AI throughout our entire organisation, from operational workflows to data-informed decision making, creating an AI-native workforce, scalable for long-term growth.
Shaping the Future of Cybersecurity
OnSecurity’s long-term vision is to lead the next generation of cybersecurity solutions by building intelligent, scalable, and human-centred systems. By treating innovation as continuous rather than episodic, the company is setting a new standard for what modern security testing should look like.
“We’re incredibly proud to be recognised for our investment-led growth,” added Conor “This award signals that the South West is home to some of the UK’s most exciting tech companies, and we’re just getting started.”
