What they say

Longbluediv

Working with a diverse range of industires, we’re proud to continuously deliver a seamless pentesting experience for our clients.

"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."

CTO at Menna
"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."

"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."

“The communication was the best part. Instead of long email chains, we could comment directly on findings, ask for clarifications, and request retests in one place.”

“OnSecurity’s approach is modern, efficient, and far less cumbersome than traditional vendors that we’ve used. Over the last two years, they’ve consistently delivered better value and responsiveness compared to others we’ve tried.”

“Working with OnSecurity has highlighted a real customer care experience. There’s a genuine feel that we’re not just another number on an Excel spreadsheet; we received a completely bespoke, professional experience. And it’s that relationship that has me arguing for OnSecurity in every renewal that happens year after year”

“Accessibility is a big factor for me, and sadly, it’s still not universal. Your team actually listened, made improvements, and within a couple of months, I had a version to test that worked perfectly. That gave me real confidence that if I ever spot something else, it’ll get sorted.”
