Firewall Server

Function
If you have an internet connection you need a firewall.

Firewall Design
The Firewall provided by D Kalmin & Co I.T.is a robust network firewall operating at the TDI/NDIS layers of the OS. Its deep inspection technology applied on both incoming and outgoing communication helps provide the highest security possible to the entire local area network, and as well as the computer it is running on.

Intrusion prevention system
The Firewall will recognize the most prevalent intrusion and hacker attacks. All security breaches are logged in the security log so that it can be reviewed at a later stage. D Kalmin will follow u p on all security breaches and will do its utmost to track down intruders

User Access Control
