Close your internal network from the outside world

A firewall is a part of a computer system or network that is designed to block unauthorized access while permitting authorized communications. It is a device configured to permit, deny, encrypt and decrypt network traffic both inbound and outbound between different private/public domains/networks.

Firewalls are essential when connecting to the internet but only of use if correctly configured. Often people create holes in firewalls to troubleshoot network connectivity without realising how vulnerable these changes have become. Sphere IT can make sure your firewalls are running effectively and secure.

How will we secure your network?

We will check the configuration and rules on your firewall and advise you if the presents or lack of particular rules could lead to potential exploits into your network. Sphere IT will document all internal software which may require inbound/outbound network connectivity to the internet and verify that rules are implemented in the correct fashion.

In most cases all outbound rules on corporate firewalls allow any traffic from the local network out. In most cases client PCs only require internet connectivity. Leaving all unused outbound traffic open leaves a big security flaw in your network. Sphere IT will work with you to close every possible hole to prevent your networks becoming a victim of unauthorized access.
