If you’ve considered the free personal firewalls just described but are looking for something better suited for long-term deployment, the following firewalls provide the capabilities and maintenance options only available from professional, commercial-grade software.
This is the software that used to be called Tiny Personal Firewall. You can have the rebadged version for a not-so-small fee, or you can get it with McAfee anti-virus protection for a lot more than a not-so-small fee. If you are interested in the protection offered by Kerio WinRoute Firewall, I recommend downloading Tiny Personal Firewall as trial software. If you like what you see, you can purchase Kerio Personal Firewall from www.kerio.com.
This is the software that used to be called Sygate Personal Firewall. You can have this upgraded version and a year of automatic updates for a small fee. If you are interested in long-term protection, Norton Firewall is a good selection. Norton is a favorite for anti-virus protection, and the anti-spyware feature is nice too. The Symantec/Norton firewall can be purchased from www.symantec.com.
If you resent that Zone Alarm is merely a ploy to get you to buy Zone Alarm Pro, wait till you find out that you actually need Zone Alarm Internet Security Suite to get both anti-virus and anti-spyware protection. Check out www.zonelabs.com for a complete marketing matrix of the Zone Alarm product line.
