Firewall

A Firewall is a boss from Rez. They appear at the end of each sub-system and are much stronger than a virus. Despite this, they weren't strong enough to keep Swayzak out when he performed his initial infection of the system, however they have learned since then and are trying to stop Swayzak from doing any further damage to the system. (But why would he? He's good now!)
