Major Sandboxie News: Sandboxie is now a free tool with plans to transition it to an open source tool

Sophos is excited to announce that we are making Sandboxie a free tool, with plans to transition it to an open source tool.

This new evolution of Sandboxie is one we are enthusiastic about, but that does not mean this was an easy decision to make.  Sandboxie has never been a significant component of Sophos’ business, and we have been exploring options for its future for a while. 

Frankly, the easiest and least costly decision for Sophos would have been to simply end of life Sandboxie. However, we love the technology too much to see it fade away.  More importantly, we love the Sandboxie community too much to do that. The Sandboxie user base represents some of the most passionate, forward thinking, and knowledgeable members of the security community and we didn’t want to let you down.

After thoughtful consideration we decided that the best way to keep Sandboxie going was to give it back to its users – transitioning it to an open source tool.  We will release more information about the open source project as we continue to work on the details.

Until the open source transition is completed we have decided to make Sandboxie completely free.  We have included a FAQ below with more information. We will continue to update this post as additional details become available. 


Sandboxie FAQ


How do I get a free license?  What features are included?

Sandboxie currently uses a license key to activate and grant access to premium features only available to paid customers (as opposed to those using a free version).  We have modified the code and have released an updated free version that does not restrict any features.  In other words, the new free license will have access to all the features previously only available to paid customers.


What if I have time left on my current Sandboxie license?

Regardless of how much time might be left on your existing Sandboxie license, in order to receive the latest updates customers with currently valid license keys will also need to install the latest unrestricted free version .  This will ensure you have access to all Sandboxie features and are using the most up-to-date version of the product.


What if I currently do not have a Sandboxie license?

Simply download the unrestricted, free version. No current or previous license is required.


When will Sandboxie be released as open source?

We are investigating making Sandboxie open source, however we are still working through the details and timeline. We will update this FAQ when we know more.


What license agreement will apply to my existing, paid licenses?  Will the same agreement apply to the unrestricted, free version that will be made available?

The license agreement under which you originally obtained the paid licenses to Sandboxie will continue to apply to those paid licenses until the expiration of the applicable license term.   A new license agreement will apply to licenses of the new unrestricted, free version of Sandboxie made available for download. 

An update EULA can be found here:


Will customer support still be available?

As part of our transition to a free and potentially open source product, Sandboxie support will become community based.  The community will include developers directly involved with Sandboxie.

  • So Sophos, you bought sandboxie to TERMINATE IT?

    What about the fortune i paid for a lifetime license?

    That was not cheap.

    Who cares if you will make open source after you assassinate this crap that doesnt even work correctly with latest windows updates?

    You bought sandboxie! Then you got hacked, removed the forums and further developement for more than half a year!

    You should not buy a decent working project to terminate it.

    So Sandboxie is not a significant part of your income? THATS BECAUSE YOU DID NOT UPGRADE THE INTERFACE THAT IS STILL ARCAIC.

    Sandboxie is a must have software that beats other similar products.


  • First off all, your tone is completley unnaceeptable.


    Secondly, Sophos bought Invinvicia (who bought it off the original author TZUK)


    Invincia had MANY products, some may have been merged into Sophos products or rebranded. Not all companies IP's that have been bought or merged necesarrily make it to the new company.


    Products get retired all the time and lifetime license does not mean they have to support the product for YOUR lifetime but the lifetime of the PRODUCT. Sophos made a business decision that when they bought Invincia they decided they did not want to the sandboxie product.

    They could have at that second removed the program and closed the website and there was nothing you could have done.

    It's like if you buy a product and it's got a 10 year warranty on it and the manufactuer goes bust then that 10 year warranty is not worth the paper it's written on.





  • Okay, so "No part can, no matter what, terminate a monetary periodic contract single sided with no penalties". 

    So, you want penalties?   

  • You talk a lot, and I mean a LOT, but you don't really say anything. So you bought a lifetime license. Well, the life of Sandboxie is now over, and so is your license. However, you can still use the software. For the rest of your life, if you so choose. Just don't update anything on your machine. Sandboxie will work like it always has. Sophos is not preventing you from using it. And if you are complaining about the lack of support, read the EULA you agreed to. There is no guarantee of support of any kind.

    Otherwise, why don't you get with your attorney and see if they can sue to get your $29 back. Until then, please STFU. Dealing with Sophos nonsense is bad enough. You are just making it worse.

    Thank you, you saved me from trying to search the exact amount I paid which I even doubt I still have somewhere from so long ago (although it might be a little lower because I purchased it in the 1st years and if I remember correctly it got some increases the following years)



    I have a question, it's a little irrelative with the subject so I apologize but it might give me some answers on why sandboxie is not profitable (and perhaps others are interested of it as well). Was there some type of lifetime license that allowed the owner to resell it as someone here implied?

  • @Argos A  I can't get into the financials around Sandboxie.  However, I can say that the idea of reselling lifetime licenses that you refer to is not something that I ever heard discussed internally. 

  • Will you ever tell us what actually happened to the other forum? In the previous updates you said the problems were not only technical. Now that you're going to make Sandboxie open source I don't see what reasons would you have to keep certain things private. Are there other parties involved?

    Also, I'm still curious to know why you made this forum private, requiring users to log in even just to read it.

  • The other forum is from a different owner, uses different software and a different host, why would the new owner want to maintain two separate forums? No one would want this.


    And these forums are not blocked in any way. I can access this very post from my phone or any other device I have which are not logged into. You keep spewing this, so maybe update your bookmarks to the proper url, or learn how your adblockers/umatrix/whatever work and how they can break sites before blaming others, because this is not an issue anyone else is having but you.

  • I also can't get into the old forums, the link gets redirected to this Sophos forum. There is a wealth of information there that is being denied to us.

  • But were there any procedures to check the possibility to be exploited (with online or offline activations) or maybe it was difficult in legal terms to prove such an exploit?
    I am asking because if a user was accurate with his claims in a post on this thread which he (or maybe Sophos for inappropriate tone) removed and also from posts he made when there was the problem with the old forum and licenses a few months back (different username but I have no doubt the same guy):
    he has a 6digit number of followers,
    he promoted Sandboxie and sold licenses (apparently his own lifetime one)

    If that's the case it means a non negligible amount of people were (and still are) willing to pay for Sandboxie but the money ended up in the wrong pocket -  and perhaps other similar cases are out there.

    The other forum is from a different owner

    The owner was Invincea, now owned by Sophos, it's not really a different owner. I'm perfectly fine if they don't want to be involved with Sandboxie's development anymore when/if they release the source code, but the old forum has a lot of valuable information that is undocumented. They could just allow the community to migrate the forum elsewhere.

    Redacted said:
    these forums are not blocked in any way

    It's not just me, multiple users have reported this. There is no ad blocking issue, that's not how ad blockers work. The last time I posted I still had to log in even just to read the forum, that's not an ad blocking issue, though, now I checked again, and I wasn't required to log in. Honestly I don't know what they're doing, I just hope they do know what they're doing.

  • Hopefully, releasing the content of the old forum will be part of the public release of the program.

    It would be great if someone can package the complete content of the forum into a compressed file that is browsable offline.
