Network firewall software is integral for preventing unauthorized access to a private network. A firewall decides whether a connection is permitted or blocked. The number one goal of a firewall is to block malicious traffic from entering the network.
No time to read the whole post? Here is our list of the seven best network firewall software:

What’s the difference between a consumer firewall and an enterprise firewall?
Consumer firewalls are designed for home-users to protect single devices and use content/packet filtering to block basic cyber attacks. Enterprise firewalls use packet filtering but also incorporate more advanced features like SSL inspection, threat intelligence, and antivirus capabilities.
These platforms are more scalable and are designed to stop more sophisticated attacks. For example, many enterprise firewalls use SSL inspection to detect more advanced encrypted attacks that cunning attackers are using to sidestep less advanced defenses.
What’s the difference between network firewalls and website application firewalls?
Network firewalls control access to your network to keep out unwanted traffic. Website Application Firewalls (WAFs) prevent attacks on websites and applications. WAFs primarily prevent SQL injection attacks, application layer attacks, and malware that compromise online services.
The 7 best network firewall software
SolarWinds Security Event Manager is a SIEM and firewall management solution. With SolarWinds Security Event Manager you can monitor your firewall and security events in real-time. The software recognizes suspicious activity such as port scanning or when the firewall blocks a device. The platform operates based on firewall rules, which come out-of-the-box but can also be customized.
To discover suspicious activity, the user has custom system filters that control what firewall events and devices show up on the screen. When the system detects a threat, the user has automated change management to change configurations automatically throughout the network. Change management shuts down vulnerabilities as soon as they are detected.
Reports allow you to record security events in more detail. There are hundreds of different default reports that comply with regulations including HIPAA, FISMA, PCI DSS, SOX, ISO, DISA, STIGs, FERPA, NERC CIP, GLBA, GPG13, and more.
SolarWinds Security Event Manager is recommended for enterprises that want a simple, reliable SIEM and firewall management solution. The program starts at $4,665 (£3,540). You can download the 30-day FREE trial.
Zscaler Cloud Firewall is a next-generation firewall solution based in the cloud that can inspect HTTP / HTTPS traffic.
