IT security is the practice of defending information from unauthorized access, disclosure, recording, use, disruption, destruction or modification.


A firewall is security system designed to prevent unauthorized access to or from a secure network, it controls the incoming and outgoing network traffic based on your firewall settings.

Firewalls can be implemented in both hardware and software, or a combination of both. In addition to limiting access to your network, a firewall is also useful for allowing remote access to your network through secure authentication certificates and logins.

Our IT engineers are trained and certified in the area of firewall implementation and configuration. The firewall will be configured according to client’s IT security needs. After the firewall implementation, we provides post-installation services such as firewall maintenance to ensure that the firewall will be maintained and upgraded with updates.
