CyberRatings.org performed an independent test of eight market leading enterprise firewall vendors. Seven products were Recommended, and one received a Caution rating. Enterprise firewalls are used to protect a trusted network from an untrusted network while allowing authorized communications to pass from one side to the other, thus facilitating secure business use of the Internet. Testing verified how effectively the firewall protected control network access, applications, and users while preventing threats (exploits and evasions), blocking malicious traffic under extended load, and remaining resistant to false positives.
