As a growing investigative company, we recently made the very wise decision to upgrade our computer systems, our security systems and the way in which we do business in the modern world. Simon from GNU Consulting was excellent in identifying our needs, understanding the challenges a confidential company such as ours faces, as well as our need to future proof ourselves in this ever-changing world. GNU consulting delivered an excellent service gave great after-sales advice and all this was conducted in a very timely fashion. Overall, without a doubt, a company we would use again without any hesitation.
