*** DISCLAIMER: I am not affiliated with any of these security companies, I just tried out their software out, out of curiosity actually, and I was semi-bored. I also tested (though not thoroughly) some leak-testing, effectiveness, look and feel, the responsiveness of my old PC (P4 2.0ghz 1GB PC100 SD-RAM, 250GB HDD, 9600Pro, DVD-RAM, Creative Audigy Sound Card… etc etc), and a little of here and there. I know some of my reviews might be biased (well, all of us are, at one point or another), or non-intelligable, and I’m pretty sure, if some techy person would read this, that person might dispute everything I say here; I will listen, but hey, I’m just posting my opinions here, and this is a case-to-case basis due to some weird compatibility issues with software, hardware and Microsoft Windows. Well, here it goes. ***
Firewalls I’ve tried within the past year:
1. Sygate Personal Firewall v5.6.2808 free
2. Outpost Firewall Free v1.0 free
3. Windows SP2 Firewall free
4. Sunbelt Kerio Personal Firewall v4.5.916 free
5. Jetico Personal Firewall v.1.0 free
6. Online Armor v2.1.0.130 free
7. Comodo Firewall Pro 3.0 (forgot which build) free
8. ZoneAlarm Pro 7.0.462.000
9. Outpost Firewall Pro 2008 v6.0.2284.253.0485
My experiences for each firewall are varied. I liked some, for whatever reason, indifferent to others, got annoyed with quite a few.
Firewall 1, Sygate, even though it’s already unsupported, it’s quite a lightweight firewall, except maybe if you’re into P2P, it kinda raises CPU utilization quite a bit, but other than that, it’s still a solid free solution and a nice replacement for Firewall 3; I had a couple of problems with Sygate, somehow leak-testing broke through, so I’m not sure if it’s might fault, but I had open ports like 139, and 445, but anyways, I reconfigured it, and closed them manually, worked like a charm. It’s quite easy to configure, because I opened the UDP and TCP ports of Warcraft III, and it worked just like that. Anyways, I’m quite happy with Sygate Personal Firewall, it is currently the firewall of the computer with ICS enabled (the gateway), since that’s the only free solution I found that’s compatible with Windows XP ICS.
Firewall 2, Outpost Firewall Free v1.0, it was nice, clean interface, but it’s kinda incompatible with Windows Security Center, it doesn’t report I’m using a firewall. And for that, I didn’t like it much, tried it for half a day, and uninstalled it. Yeah, I’m unfair, sorry for that, but it’s a pet-peeve of mine. But it’s lightweight.
Firewall 3, nothing to see here, move along. kidding! This was my first firewall on my Windows XP ICS Gateway, I configured it to port-forward to my other PC, for my P2P softwares. Really basic stuff, no extras, system responsiveness didn’t even change; because it’s preinstalled. It’s probably enough for most users.
Firewall 4, 5: Free firewall solutions, which I didn’t like much, it’s supposed to be solid free solutions, but I wasn’t enamored by their interface, I don’t know if I found them clunky or something, but I just didn’t like them. I am being unfair for not giving those programs a chance to prove themselves, but then again, they’re free, so I don’t care. Both are somewhat light on computer resource, but I find Sygate lighter for some reason. Tried both for about 1-2 hours.
Firewall 6, 7: Supposedly the best of breed on paid and unpaid software firewalls, passes all kinds of leaktesting based on Matousec; my verdict? They’re both taxing on my system. Online Armor really slowed down my system, I was using WinAmp, using P2Ps, running a real-time virus scanner at the background (NOD32 3.0 at that time), but my system went to a crawl. Even the mouse was like at 4 FPS or something. Uninstalled it in 15 mins, after the “getting to know the system” process at the start. Comodo gives me the impression it’s really powerful, and I believe it really is. But the proactive protection thing really got me annoyed. I closed some of the protection options, to speed up the system, but it was still kinda slow for me, a bit unfair because Kaspersky AV 7 was running, but I also closed some of of its protection levels, anyways, it’s slow, a bit taxing on my system, so I removed it after about 3 hours.
Firewall 8, ZAP, one of my favorite firewalls around, the stats thing on the main tab of the firewall interface really gives a user some sense of security, gazillions of whatever blocked intrusions, I’m pretty sure 90% of those are false positives, but hey, numbers are cool, I’m like OMFG this firewall has saved my ass too many times. The OS firewall, program control and some of it’s features are nice, it’s really useful for me, and it’s quite easy to understand, unfortunately, I dunno if I’m being a bit n00bish for saying this, but sometimes the firewall doesn’t save the program permissions, I’ve checked the box, and allowed the program, but it sometimes comes back, prolly because that specific program got updated or something, but hey, shouldn’t a paid firewall recognize those legit programs on the fly? It’s not like those programs are obscure ones. But I still like ZoneAlarm Pro, it’s just slow. Makes my games slow. Makes my PC a bit slow. Eats too much RAM, I dunno why, but VSMON always eats RAM, even if I turn off the virus monitoring. I suppose it’s a ‘feature’ of Zonealarm to be a memory hog. Good protection if you know how to use it, taxing on a computer if you have entry-level specs. This is also compatible with ICS, but, sometimes it breaks, dunno why.
Firewall 9, Outpost Firewall Pro 2008, all I can say right now is *whoa*, it’s quite nice, sleek interface, probably better than all, if not most of the firewalls mentioned here. It’s currently my firewall of choice, and would recommend it to ANYONE, as long as they have the pocket to pay for it (if not, I’ll recommend Sygate). It hasn’t given my any trouble, I just don’t like it’s default icon, a blue shield with question mark, I thought it was just learning the computer, that’s why it’s like that, but after a while, it’s just like that. It’s my WTH moment with this firewall, I was thinking it’s like a green or gray shield, or something with a CHECK, not with a question mark, it’s like it doesn’t know what’s it doing. But overall, feature wise, protection wise, it’s a sound and solid firewall. It’s a good investment. It’s simplicity and clean design really attracts me, I thought Agnitum sucked before, but heck, I was very wrong. It’s probably the best firewall on retail right now.
RANKING (best to good, top 3): Outpost Firewall Pro 2008, Sygate Personal Firewall, ZoneAlarm Pro
*** a hardware router/firewall would be the most effective solution though, or an old PC turned hardware firewall, but I think I’m speaking for the less techy people out there, who has a computer (or two/three via ICS) online with a connection. Anyways, any comment is welcome, and I’ll apologize in advance because I’ll be a little late on approving comments or replying to them, but thanks also in advance for commenting and especially reading this geeky entry. ***
