However, one of the best ways to make sure that these kinds of problems don't arise in the first place is to use a <a href="https://www.extnoc.com/managed-firewall-services/">managed firewall service</a>. Our security professionals are always receiving intelligence from throughout the world. The Counter Threat Unitâ„¢ (CTU) provides research that is incorporated into each of our security offerings. Additionally, this enables our professionals to enhance policies and carry out even more accurate firewall log file analysis.

ExterNetworks uses our Attacker Database listing as one of its main tools for this. An exhaustive compilation of IP addresses that are known to have been compromised and utilized by attackers is included in this section. Our network security researchers add a new entry to this database whenever they discover an attacker using a different IP address.
