Firewall Configuration
A firewall only protects you as well as it is configured.
Overview
The firewall is the control point between your business and everything outside it. Correct configuration determines whether it actually enforces the policy you intend.
A firewall installed with default settings, or one that has accumulated years of one-off exceptions, can give a false sense of protection. Overly permissive rules, unused open ports and unclear policies are common findings.
NexLink helps you install, configure and tune firewall infrastructure so traffic filtering matches how your business really operates, and so the rule set stays understandable and maintainable.
