  • SD WAN  


  • SD WAN Managed Services 
  • SD WAN Service Provider 


  • Global Tier 1 Optical IP Backbone: Cogent offers high quality services worldwide, whilst keeping costs low.
  • Fibre Optic connectivity: Direct fibre connection from the premises into Cogent’s network, providing high speeds
  • Reviews from customers addressing the level of support from IT services are consistently positive.


  • Cogent’s focus on fibre optic services means that other underlay options are often perceived as limited. 
  • Possible poor connectivity in non-metro areas, as Cogent’s backbone is focused in large cities.

Netify Review:

Ideally suited for single to large multi-site enterprises that require global, dedicated bandwidth backed by strong SLAs. As an ethernet-based solution, per bit/byte costs are kept competitive whilst also keeping high bandwidth speeds. Cogent’s high capacity IP network allows high speed (up to 100Gbps) connectivity to large bandwidth connections whilst remaining at a competitive price. Provides services for corporate and net centric businesses with a facilities based network spanning: North America, South America, Europe, Asia, Australia and Africa.
