I've been told by various PCI auditors that a noncommercial/FOSS firewall could pass as long as you have implemented the necessary controls such as encryption/logging/management and passing actual testing.

In these cases I rely on the vendor’s public statements about their development processes and certifications (e.g., ICSA). Commercial products often disclose their development processes and even run in-house security threat research groups that publish to the community.

For example,<> lists certifications by vendor for those that have passed their test regimen, and both Dell SonicWall and Fortinet Fortigate are shown to be current. PFSense isn’t listed, and although it is theoretically vetted by many users, there is no guarantee of recency or thoroughness of the test regimen.

While these regulatory organizations don’t require specific overall firewall certifications, they do require various specific standards, such as encryption strength, logging, VPN timeouts, etc. I don’t know if PFsense meets these requirements, as they don’t say so on their site. Companies like Dell publish white papers on their compliance with each regulatory organization.
