Our Story

When James Hadley first scribbled down his idea, he had no idea it would later become a platform that the likes of Goldman Sachs and Summit Partners would want to invest in. This is our story…

A brief history

After delivering GCHQ’s cyber school, James realised that passive classroom-based training suited neither the people nor the pace of cybersecurity. The content dated quickly, and its one-dimensional nature meant the creative minds in the room quickly disengaged. He knew that a practical online solution was needed – one that would allow learners to continuously hone their skills, get to grips with new threats, and become familiar with the latest tools and techniques. In short, they needed a platform that would help them keep up with the attackers.

On the flip side, businesses have never struggled more to ensure their security teams are well resourced, well trained, and well prepared. Their focus has been on building their tech stacks – not on the people behind the screens. As a result, the skills shortage is only growing as security teams are overworked and undertrained, and organizations are left scrambling to catch up with the ever-shifting threat landscape.

Enter Immersive Labs.

Immersive Labs is the leader in people-centric cyber resilience. We help organizations continuously assess, build, and prove their cyber workforce resilience for teams across the entire organization, from front-line cybersecurity and development teams to Board-level executives. We provide realistic simulations and hands-on cybersecurity labs to evaluate individual and team capabilities and decision-making against the latest threats.

We’ve grown to over 300 employees across the UK, US and EMEA, with hubs in Bristol, UK and Boston, MA. To date, we’ve secured $123 million in investment from Insight Partners, Menlo Ventures, Citi Ventures, Summit Partners and Goldman Sachs. Our technology is already helping over 300 enterprises around the world, including AirBnB, P&G, Citibank, Sophos and the NHS, while around 5,000 labs are completed every single day.
