Founded in Edinburgh in 2016, we’re one of the fastest growing cyber security companies in the UK and North America, serving over 400 customers on four continents.

In September 2024, Quorum Cyber acquired Canada-based, Microsoft Solutions Partner for Security, Difenda.

This was closely followed in December 2024 by the acquisition of US-based, Kivu Consulting, a global cyber security firm with world-leading incident response capabilities.
