Real world reviews

I always find [GRC Solutions] easy to work with. The consultant involved was very professional and friendly, providing plenty of updates throughout the test and clearly explained his findings. ”

Gordon

Good grief, what an eye-opener this was! We chose [GRC Solutions] because the initial scoping call revealed their pen testers had heard about our not-so-common software setup and their cost was more realistic than the other quotes. ”

Time

It was a pleasure to work with the [GRC Solutions] team for this pen testing project - from clear guidance from the account manager through to regular updates from the testers themselves. Will use again.”
