“Through a recommendation I employed CNS to assist in a firewall upgrade project. From that point on the relationship between SITA UK and CNS has grown. In all projects that involve information security, CNS are included in the tender process, and on all occasions where their proposal has been successful, CNS have always delivered to budget, to time and ensure that each project is a success. To add to this, CNS have now won a contract for a Managed Service and are an integral part of the security team at SITA UK. I would personally recommend CNS as a solution provider and more importantly as a trusted partner.”
