Summary
#1 choice for the paranoid user's IT-toolbox!

Pros
This nifty application lets you monitor (in detail) the communication between processes running on your PC and the outside world. And, it has a very nice userinterface! So if youre wondering if "something" has hijacked you PC, this is it.
Cons
I would love something like wireshark (ethereal) integrated with this product, so you can actually rip the contents of a suspicious connection.
Summary
Tried it. Wiped it. A Dirty Program.

Pros
Very effective firewall. Could be up there with the best except for some MAJOR problems.
Cons
On 3 diffent PC's. Same problems occured. 1. Random shutdowns. 2. C: router problems. Whatever this is. 3. Difficult to learn and somewhat unsupported in the Help regions.
Summary
Bug detected in the download, but maybe it was a false positive, or could be the cause of the random shut-downs. Would not install after bug cleaned so reinstated it. Sorry I did. TPF 6.5 is dangerous on my PC's. Unstable, and too many WTF? issues. Try the TPF2 - 2.0.14 free version (2001 version?). Not too bad and extremely simple, but had one PC randomly shut down within the first few days, but 2 Weeks later, all OK. Has lots of easy to configure stuff too. Not sure yet if it is good, excellent or whatever. Still can't beat the very annoying but very powerful free Comodo FW for protection

Pros
nothing
Cons
it used to be free and good but wow it changed
Summary
It Was Good Before
gway17November 28, 2007
Pros
At first it seemed to be a pain. Then I realized that If it seemed irritating, it was because it was doing what it was designed to do.It worked well for a long time and did a very good job.Now, there must be holes that a virus can get thru as I've had several that "ride" in on my TPF. Turned off TPF and I haven't had any more problems.Too bad as it was a nice little product.
Cons
Seems to no longer block the bad stuff.A bit pricey for what it does.
Summary
yes it block,but hill it's suck
MANX6161June 3, 2007
Pros
Could and can block any thing from connecting the internet. monitor any traffic
Cons
it's not for regular or advance users,it's only for programmers and hackers. very very confusing, it aske u about any thing try to make a connection (even if ur opening a photo)
Summary
Useless and irritating
WillPowerMarch 1, 2007
Pros
None
Cons
Can't even register or buy it anymore so whats the point?
Summary
Decent but not fully functional
warspartanJanuary 22, 2007
Pros
This is a small download and I think it still works unsupported.
Cons
you can't access anything on it, it just runs and there are no viruses, if just will make a lousy computer crash, because, its lousy. Completely safe and if you don't believe me scan it! its that easy!
Summary
Excellent but requires effort. Sadly, it is virtually unsupported.
ITsourceAugust 16, 2006
Pros
If you spend the time to learn the full functionality of this product, you will grow to appreciate what makes this firewall powerful in the extreme and be rewarded with excellent intrusion prevention for your Windows or Windows Server run PC.
Cons
Will initially ask permission for everything that happens on your system, which can become annoying even for experienced users. This product is virtually unsupported since the acquisition of Tiny Software by Computer Associates.
Summary
used to be...
gbh1935June 5, 2006
Pros
used to be a favoriate of mine, but...
Cons
but now with the firewalls built into everything (home routers, norton, xp)I don't find it as useful as it used to be.
Summary

Developer’s Description

By Tiny Software

Protect your system with firewall from hacker attacks.

Tiny Personal Firewall integrates several protection layers for the ultimate safety of the desktop and server. Traditional Firewall blocks the network traffic based on protocol, ports, and application. Intrusion Detection and Prevention blocks the network traffic based on the content of packets. Malicious packet content is frequently used by hackers exploiting vulnerabilities of otherwise trusted applications, such as Windows kernel components, IIS and others. Application Security controls the behavior of applications and controls whether the application may start itself or whether it may start others.

Also limited are accesses to specific internal resources such as hard disk, CD-ROM, and system. Files and system protection protects your valuable data against to damage by other untrusted programs or by trusted programs run by untrusted users.
