Testimonials

Here at Miles Macadam, working for both the Private and Public sectors, we found that we were increasingly being expected to hold Cyber Essentials certification right from the point of tendering for potential work. We were initially daunted by this as IT, and particularly IT Security, are so far outside of our core skills that we had no idea where to start.

 

We needn’t have worried though as Pete was able to take us through the process smoothly and efficiently – handling it with the ease you would expect from a professional provider. We are now in our second year of certification, and the renewal was just as straightforward.
