Probably the Best Free Security List in the World

Probably the Best Free Security List in the World - Page Index
1. Introduction

This article contains a comprehensive list of free security-related programs or web applications for Windows XP and later Windows PC-based operating systems. The few non-free programs on this list are included because they are of high merit (in our opinion) and lack a comparable free alternative. This list also includes links to webpages that contain security-related information.

We don't give specific recommendations on this list except for the personal suggestions of the list authors. If you are seeking recommendations then check out Gizmo's Freeware The Best Free Security Software for PC. Gizmo's Freeware also offers free personalized security advice via the Security Wizard.

We usually list a given item on this list only once, putting it where we think it best belongs. However, sometimes we list a given item more than once if we feel strongly enough that it belongs in multiple locations.

We check all links with Web of Trust. Only links that are rated by Web of Trust as green are shown as hyperlinks. Links that are rated by Web of Trust as yellow are shown as obfuscated links; in such cases copy and paste the obfuscated link to your browser's address bar, then replace [COLON] with : and [DOT] with . to change the obfuscated link into a valid URL. Links that are rated by Web of Trust as red aren't shown either as hyperlinks or obfuscated links. Links that directly link to files are shown as obfuscated links.

We usually don't test the programs or web applications on this list. We usually don't scan the programs on this list with antivirus software.

We usually don't check these keys for a given item: " Adware that may or may not be optional," " Includes software recommendations via OpenCandy," or " Nagware." We usually check key " Program that works without installation" for a given program by using only online information, not by testing the given program.

We encourage you to use the comments section below to let us know about dead links, incorrect links, links to malicious websites, links that include malicious software, incorrect or missing keys for a given item, items that could be added to the list, programs that work only on pre-Windows XP operating systems, or any other issues. You may also use the comments section to tell us about your experience with a particular program or web application. We value these suggestions and look carefully at each one.

Nice list. Some links point to finnish sites as expected, some other are outdated and other are not relevant, but overall you did a good job, thanks !

by ako (not verified) on 5. June 2009 - 21:02  (23126)


What links are outdated? (I know there are products that are discontinued, but have included them if I find them still useful.)

by Anonymous on 8. June 2009 - 20:42  (23354)

Wow Amazing!! Someone can tell me why i didnt get this list by my rss subscription?

by peter on 8. June 2009 - 23:16  (23361)

You subscribe to a Finnish site? You speak that language?

by PsychEroc on 9. June 2009 - 0:18  (23365)

I really like comprehensiveness and this is it!
Only there are so many choices.
I'd like to know the Editor's Choice and the People's Choice (most popular) for each category. But that opens a whole other can of worms.
I wonder if Gizmo's "Top Pics" could be indicated at least.

by peter on 9. June 2009 - 6:46  (23383)

I don't really understand the last line of your comment.Please bear in mind that this list is copied from two other sites (with full permission, natch) It gets updated sometimes, so any edits made on this page will then be lost. Have I misunderstood you. PsychEroc?

by ako (not verified) on 9. June 2009 - 10:46  (23398)


I have tried to have a kind of order "the better more close to top", but this is of course subjective at best.

by JonathanT on 9. June 2009 - 11:48  (23401)

Great list!

What's the difference between UAC-control and Better UAC?

by PsychEroc on 9. June 2009 - 13:19  (23409)

I thought it would be useful, for example, to put a star by the products that are Gizmo's Top Picks.

by peter on 9. June 2009 - 13:32  (23410)

You are very welcome to do that, but you'll have to repeat every time the list gets update (we don't know how often that will happen).

by PsychEroc on 10. June 2009 - 3:28  (23474)

Someone mentioned SafeSpace in a comment for another article, but it's not listed here.
It's no longer being developed, but just wondered if you are aware of it AKO?

by ako (not verified) on 10. June 2009 - 8:32  (23481)

Thanks for a comment. I decided to leave it out as there are developed alternatives, and for a (policy-based) sandbox I expect full security, which is only guaranteed by continuous development. SP may be still very valid, though.

A good example of a very valid undeveloped product is Processguard. It still blocks processes as well as ever.

by ako (not verified) on 10. June 2009 - 8:33  (23482)

Norton has a kind of whitelist included.

by ako (not verified) on 10. June 2009 - 8:51  (23485)

If you are willing to help here. we could think about this.

by peter on 10. June 2009 - 9:48  (23490)

Maybe that's worth explaining in the Article, at the top or somewhere in the bit "This list was kindly provided...
But it's just a sentence, I think.

by Anonymous on 12. June 2009 - 6:27  (23657)

These are for all practical purposes Windows tools, correct?
It would be nice to see a delimiter of OS applicability...just sayin'.

Just started using Hamachi as a free VPN solution to replace Cisco's non-Vista compatible VPN client software. It ROCKS!

Thanks so much for your efforts to provide this all-encompasing list "of everthing you'll ever need"!!! Am saving it in a Folder in case of future need(s)!!

for virtualization I and many people use VirtualPC,
you list "Microsoft" but the name of the program is actually VirtualPC, not Microsoft.

Seems you have forgotten LastPass - my favorite pass keeper


by Anonymous on 12. June 2009 - 14:07  (23678)

Surprised to not see SNORT, or for that matter, an entire NIDS category. Still, nice list that pointed me to a new series of tolls I wasn't aware of. Thanks

This is a great list. I've been around a long time but there are plenty of items I haven't encountered before. I also found a dodgy site but only indirectly from the list. Sometimes I check out the ads! Fantastic effort.

Just a comment. I like free stuff so I can try it for a while but I make a point of buying anything I need that is really good. That way I feel I'm supporting those vendors worth supporting. Usually the paid version is worth paying for so it's a win-win.

by Anonymous on 12. June 2009 - 14:25  (23681)

"Surprised a program you like is not on the list" - "the list is not complete without...." - "I prefer to use (such and such)" - "Some of the links are outdated" .......... nag nag nag.... bitch...
The list is free people and someone has spent much time and effort to present it to you... that doesn't give you licence to complain.

Try giving instead of taking and complaining. Seems it's true that our value is judged by what we charge for a service.

Twister is NOT free. It has a BUY NOW button. How is that free?

by Anonymous on 12. June 2009 - 16:07  (23689)

Yep, first thing I noticed too. Lastpass is absolutely brilliant. It is so brilliant, I voluntarily paid money for it!

A very helpful list! Thank you for putting it together.

What about Untagle?
Free basic firewall to re-purpose hardware (linux-based).
I have no affiliation/investment with this

Loki VPN Client ( "Loki Network Project is free VPN service and SSL based free VPN server. It is an opportunity to protect your private data (IP address, e-mail/FTP/HTTP passwords, web-sites visited, uploaded/downloaded files and etc...) and bypass certain Internet access limitations you may have at your location."

I have to chuckle because this list points out my main problem with free security software -- the multitude of combinations. You have to find an optimal combination of products, avoiding functional overlap, while minimizing security holes. For example, multiple product categories offer what they call HIPS. If my firewall has HIPS, can I turn it off in my anti-malware and/or anti-virus package? Same for popup blockers, or anti-rootkit, etc., etc., etc. I've even gone through the exercise laying it all out on a spreadsheet to try and identify optimal combinations, but came to the conclusion that there's a fundamental flaw here -- these products just aren't designed to work together.

Now, if someone did some actual vulnerability testing with product combinations, I would be very interested in that. Until then, I'm willing to pay for an integrated, full-function security suite.
