ISN managed our offices and data centre relocations brilliantly, making the transition very smooth. They were always on site, ready with support and provided clear, useful handover documents. We’ve since engaged them to provide a fully managed service for our UK networks, firewalls and remote server access. We find ISN highly proactive and their service and response times are just as good whether it’s midday or midnight.
