Comodo Firewall Pro 3.0.25.378

The problem with third party firewalls is that sometimes they just simply become a nuisance. Blocking traffic that you want, and rejecting those you need such as daily updates and P2P software. I was therefore pleased to find that Comodo Firewall falls into none of the above categories ? simple, effective and discrete, this is definitely one of the better firewalls out there.


Like all firewalls, this program basically filters ingoing and outgoing traffic to your PC. However, in the case of Comodo, it also monitors components such as driver files that are used to initiate network connections as well as other running processes to check for problems. Of course, it also features standard options like port scanning, adjustable security levels and trusted networks etc. The interface is not particularly attractive but its easy to find your way around which is the most important thing.
One outstanding feature of Comodo is that you can set it as part of your PCs boot sequence which means that its activated before any pesky program or intruder can access your network connection. It also does not seem to slow down connection speeds like some firewalls do ? ZoneAlarm is particularly guilty of this. Many users report on forums that they changed to Comodo for this reason alone,. Its also much lighter on CPU resources than the former and you wont find it hogging your RAM.
On the downside, it doesnt seem very efficient at remembering permissions. On several occasions, it kept asking whether to grant permission to connections that Id already authorised just seconds earlier. Better to be safe than sorry but this did get a bit annoying.
Overall, Comodo Firewall is easy to use for novice users, but includes enough advanced TCP options for advanced users to customise it for specialised networks. Considering its absolutely free ? you only need to complete a free registration after 30 days use ? this is an excellent firewall.
