In order to prevent unwanted activity to or from a server, firewall and Intrusion Detection Systems (IDS) can be the last layer of protection between a server and the Internet.

WebDeal has chosen the open source firewall vendor Astaro for our high performance redundant firewall setup. Astaro has a very high level of security, as concluded also by ICSA Labs and other independent security analysts.

When do you need a firewall ?

It's common to believe that firewalls increase the security of a server, but that is not entirely true. A flawlessly maintained server without security holes in the software layer will not necessarily need a firewall.

Here at WebDeal, we build a double set of protection systems for all our dedicated managed servers. We use firewall and IDS to prevent unauthorised access to the server from the outside and the operating system's security technology to prevent unauthorized access from the inside out.
