Paul Geary
Head of Dev at Cortech
We were actively pursuing ISO 27001 and knew we needed the right monitoring in place. OnSecurity stood out, not just as a pentesting provider, but as a partner who understood what modern, growing businesses like ours need..

Pentest providers should give clients a net-positive of their time. If clients are having to spend a lot of time managing the process, it becomes tedious. OnSecurity’s services were quick and straightforward.

Ben Harper
CTO & Co-Founder at Sitehop
The simplicity of OnSecurity’s platform was the selling point for us! The tool fits perfectly into our security programme and is simple enough for the team to follow. We have a very streamlined department so something that could manage all aspects of our vulnerability management was key.
