There are many main parts of network security services to take into consideration, the following:

Firewall configuration review, to test how the rules currently accompanied by the firewall, and the kind of firewall used, work towards the given situation.

Detailed audit of computers and devices (like routers and firewalls), and their location for the network. This includes overview of any DMZ (De-Militarised Zone) browsing front of your respective organisation's core network.

Network vulnerability assessment, to check previously-addressed vulnerabilities to make sure that they're still covered by effective countermeasures.

Penetration testing, to probe the defences actively for new vulnerabilities. This kind of test needs to be approached with caution, since it can disrupt operational systems or create a temporary denial and services information. The guidelines of engagement should be agreed ahead of time and hang on paper.
