There are some essential regions of network security offerings to don’t forget, as follows:
Firewall configuration evaluate, to check that the guidelines currently followed via the firewall, and the kind of firewall used, are suitable to the given state of affairs.

Network vulnerability evaluation, to check previously-addressed vulnerabilities to ensure that they are nonetheless blanketed with the aid of powerful countermeasures.
