This list (earlier "Probably the Best Free Security List in the World") contains thousands of links to free security-related Windows desktop applications and web applications, with the goal of listing everything available that's not malicious or of low usefulness. This list doesn't include Windows desktop applications that work on only pre-Windows XP operating systems. This list also contains links to pages that contain security-related information. This list does not give recommendations ( except for the My Choices page ), but it contains links to other Gizmo's Freeware pages that give recommendations.

Use the Windows desktop applications or web applications on this list at your discretion. We usually don't test the Windows desktop applications or web applications on this list, and we usually don't scan the Windows desktop applications on this list with antivirus software. Some of the links in the Related Links section on this page give tips on deciding whether a given Windows desktop application or website is safe to use.

We periodically check all links on this list with Web of Trust. Only links that are rated by Web of Trust as green or unrated are shown as hyperlinks. Links that are rated by Web of Trust as yellow are shown as obfuscated links. Links that are rated by Web of Trust as red aren't allowed on this list. Links that directly link to files are shown as obfuscated links. To change an obfuscated link into a valid link, copy and paste the obfuscated link to your browser's address bar, then replace [COLON] with : and [DOT] with a period.

Use the comments section below, or this (or this) forum thread, to let us know about issues, or suggestions for items that could be added to the list.

Ask.Moe is a non-profit, open source, privacy focused search engine:

I could not find enough information on this. 

Infinity Search is a privacy search engine:

This seems ok.

Spycheck - helps you determine if your system is vulnerable to Thunderspy:


Whoogle Search - get Google search results, but without any ads, javascript, AMP links, cookies, or IP address tracking:


Eureka is a simple tool to encrypt files and folders:


I find this questionable.

Me too, actually: Better to stay away from that one. Looks like some other search engines are also shady:
Super Dimension Fortress lets you register an anonymous user over ssh: JoshWho - a search engine with end-to-end encryption:

JoshWho added. Can you explain what is the idea of SDF?

You can read about it here: Basic version is free ...
Runnaroo: - the search engine that cryptographically protects your privacy: "... Inspired in the ways of the medieval Knights Templar, the CTemplar mail was created to provide an anonymous and end-to-end encrypted mail to anyone who needs their communications shielded from prying eyes ...": SMAILPRO - Temp Mail And Gmail Accounts Free: Gomu is a search engine that doesn't track you:

Thanks, I'll check these.

EDIT: I accepted others, but there was too little information on


Are there any legitimate good free "disposable phone number sites"?
Please add to list.

Such data is outside of scope of this list.

Would this be categorized under another list? Any good place to look? Thanks.

I have no expertise on this. By googling you will find many canditates. Please do your  due diligance and inform us on your findings.

The link you give for I2P takes you to a different link: Firefox blocks it as an insecure site and if I enter the link on WOT website, it says it has no information on this site.

Thank you, I fixed it.

OK, I give up, what's an LUA?

There is link on My Choices.

"Least user access" or "least-privilege user account".

I've just discovered WOT (Web of Trust) has been selling user data to third parties. Firefox has now blocked the plugin for security violations.

I went to their web site only to face a pop-up with no exit. I searched FAQs and the Forum and there was no mention of this.
It seems WOT has lost its status as a "security" product.

Hi all;

I simply don't understand the fuss about WOT. As I wrote in my Jan 25th. 2017 post on my blog "WOT has a few month ago modified their end user license agreement to conform more closely to what the add-on all can do. No surprise to me that they collect some information on the things you search for and where you then click on. Google does that for years and nobody gives a hoot.".

Furthermore I am of the opinion and have LOTS of experiences with my customers; they all value WOT highly. But many people "... don't seem to see the value of WOT for the normal non-geek end user and remain stubbornly on their negative stance towards WOT. ".

And later in the same post: "Mozilla even tricks people into disabling or removing WOT - despite the fact that there is no even remotely similar functionality available anywhere else.".

Finally: "It is a shame but I have to tell my customers that they have to use Google Chrome for their web searches if they want the advantages of WOT".

Again, AFAIK Google does pretty much the same thing (collecting information about us) but nobody stopped using Google for searching or any of the other Google services. Hypocrisy?

If you know where there is "... similar functionality available anywhere else..." then PLEASE, pretty please let me/us know here. With "similar functionality" I mean similar to WOT.


It's simple, really. A security app should not be compromising your security. All of them have done it at some point. Mozilla is not the bad guy here. Sure you can re-enable WOT but theres a good reason they've disabled it.

It's not that they're tracking your browsing - thats to be expected for something to give you these results. The issue is selling that data to third parties without removing user-identifiable information. And you don't know who those parties are. That's not security.

Google is not a security tool. I, like many others, use DuckDuckGo. It searches Google with minimal tracking. People do give a hoot, I'm afraid. More should.

Mozilla doesn't trick anyone. They disable plugins that they discover compromise your security. Thats a good feature.
Google updates have broken WOT in search results on several occasions. I didn't see such a cry over that.

I fully agree WOT was a great tool and have recommended it for years. As this is probably their funding model, I doubt much will change. As I also mentioned, it's a bad sign when a companies web site isn't behaving properly/ maintained. I've removed WOT.

There are other tools that do very similar but most of them have been bought up and integrated with security suites. Site Advisor into McAfee, for example.
