Perimeter Network

A perimeter network allows you to gain better control when securing your data and application services by improving control over access to resources and reducing unauthenticated network traffic on your Local Area Networks.

A perimeter network, or De-Militarised Zone network (DMZ) as it is often referred, is a separate network, or multiple separate networks, segregated from the internal network and secured both internally and externally by a firewall. It is used to place application services such as web servers, some email servers and other public facing servers, to protect your internal network from unauthenticated external access.

Access in and out of the DMZ network is controlled by Firewall rules. Firewall rules controlling routes are configured to allow specific access from the internet and then to allow specific and definitive access to internal services.

We offer independent technical consultancy to design a perimeter (DMZ) network solution that allows you to control and secure your network, provide secure user access to corporate sources and applications, whilst reducing the risk of unauthenticated network traffic on your main LANs.
