Defend your Enterprise with Expert Firewall Management

Firewalls block network traffic from malicious or suspicious sources. This can help defend against cyberattacks that may not include a typical virus. For example, phishers could spoof your organization's email and pretend to be an internal sender. Firewalls block the message from even coming through. You can also limit network activity to certain IP addresses, access ports, or applications to protect your data and prevent unauthorized access.

No. While they do block network traffic from known malicious sources (or those with vulnerabilities), your devices may contract a virus from removable hardware, spammy web links, and other user activity. We recommend both firewalls and antivirus protection as part of a complete cybersecurity plan.

Firewalls come in three main types:

• Traditional firewalls limit network traffic to pre-defined sources, destinations, or ports. You can set rules for access and automatically block suspicious sources. These are ideal for organizations that need to heavily restrict network activity.
• Proxy-based firewalls force devices to connect to an intermediary. This is one of the most secure, although it can sometimes delay connection speed.
• Next-generation firewalls set rules for network activity and also filter traffic for certain applications. They also offer malware detection and blocking, which makes them a comprehensive solution for many businesses.

As your various software gets updated or new devices join the network, new vulnerabilities arise. Your firewall configuration may not support certain software versions. Over time, its rules become redundant or unnecessary. Only regular auditing, testing, and updates can ensure that your firewall is operating as it should.
