Every firewall has a set of rules for managing incoming and outgoing traffic. We recommend reviewing these rules regularly. Things may have changed since you initially set up the firewall.
You want to make sure old user accounts are not active anymore or add new ones. Over time parameters like application usage and internet speed may change. We advise looking over these rules at least once per year to ensure they are still valid and intact.
We often see problems with firewalls that were set up three or four years ago, and the rules are not valid anymore or not very cohesive. If you are not sure how to check or modify your firewall rules, reach out to us. We can help you with that.
