Our world is experiencing unprecedented change. In turn, the challenges and risks presented are continuously evolving. Net-Defence was established to meet this challenge and is lead by a recognised thought leader in this field.

In 1997, our Managing Director, former GCHQ Consultant, Alan Greig, was posed with a security requirement that could no longer be resolved through traditional approaches and methods. The emergence of the internet was beginning to radically transform the security landscape, he saw the gravity this new virtual network could have, and the new risks it would create. This rapidly evolving environment also needed new security solutions – this was the genesis of Net-Defence.
