Why Net-Defence?

Looking for reasons to choose -defence? Here are some kind words from our customers and suppliers.

“We have been a customer of Net-Defence for many years and approached them when we looked to change out old on-premise telephone system. They provided the best proposal out of 4 competing bids, both cost and implementation in a short timeframe. They have been very supportive all the way through the process and have delivered a great product.”

He was a pleasure to work with.”

“White Digital operates in a very busy marketplace and we're always looking for ways to show we are a well-organised business. We saw ISO 27001 as a benchmark to measure ourselves against and a badge to show our clients we can deliver long term projects effectively and efficiently. We also get asked to tender for work and ISO accreditation is sometimes a pre-requisite. Net Defence were the standout of 3 agencies we had come in to talk us through how they could help us achieve the accreditation. They haven't disappointed and have made the process as painless as possible. Thank you to the whole team for their help”

“John guided us through our Cyber Essentials and Cyber Essentials Plus renewal professionally and efficiently. He was very accommodating with our office visit whilst we are hybrid working. Whilst the renewals are not always the easiest to get through, with the Net Defence Team’s advice and experience, we were assessed and passed painlessly. We look forward to working with Net-Defence again for next years renewal (and its not often you look forward to audits!)”

“At Scott Logic, we were confident with our processes and procedures but we needed to formalise these to prove to our customers and prospects that we were a reliable company to work with.

Thanks to the tenacity of the Net-Defence team, we now have the accreditations that prove we manage information securely and have processes in place to deliver consistent quality to our customers and prospective clients.”
