Although appreciated for being released as freeware, there is a growing community of users frustrated by the lack of developer support in correcting known issues in the versions 2.x. An example is the high CPU usage by CPF.EXE due to input/output processing for writing to a log file, which has been a known issue since February 2007.^[10]

Additionally, there are a few serious vulnerabilities in the firewall's design which can be exploited locally, meaning that, while the firewall's protection remains solid, a malware can be designed to shut down or bypass the firewall's control functions if it somehow makes it onto the computer. Several other critical vulnerabilities are known which have not been disclosed. All are as of 2.4.18.184 still unpatched.^[11] There is uncertainty as to whether they will be fixed in version 2.5 or not, but an administrator on the beta forum has stated that version 3 should not have any critical bugs left. A test of version 3.0.22.349 by matousec.com successfully blocked 95% of the attacks in their battery.^[12]
