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.

    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.

  • In reply to Redacted:

    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.

  • In reply to Seth Geftic:

    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.

  • In reply to Redacted:

    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.

    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.

  • In reply to Vivaldo Sagese:

    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.

  • I just want to say:

     Thank you so much for making this awesome tool open source!


    To bad though no money can be made of it. I'll guess it's just to complicated for most users, who want everything done for them.

  • In reply to soccerfan:

    I'm using version 5.22 on a Windows Vista system, and recently passed the 30-day point where "nagging" begins:

    A new free version just for XP and Vista is obviously not a reasonable request, but could we somehow get a Product Key?

  • In reply to Floyd Fix:

    Since thry are not longer selling licenses, imho they could just release a offline activation tool that you just runt to activate for 35600 days or so

  • Fine, but will Sandboxie still be maintained to be compatible with Windows updates and web developments ?

  • In reply to Yabbadoo:

    Highly unlikely imo

  • In reply to henry g:

    Gradual descent into being unusable.

    They say this -

    "Sandboxie support will become community based.  The community will include developers directly involved with Sandboxie."

    Unless these people have the access and ability to change and update the Sandboxie software, they will be restricted to simply answering questions and that is totally inadequate.

  • In reply to Yabbadoo:


    Unless these people have the access and ability to change and update the Sandboxie software,


    Thats what we will have once sandboxie will be made open source.

  • In reply to Pedro López:

    They should just give it back to Tzuk and let him charge a fee for continued development.

    TZUK, COME BACK !!!!

  • In reply to carl COBAIN:

    "Like i said, no point talking to leftists."

    lmao, another rightwinger trolling another internet forum...

  • May I inquire whats the progress on opensourcing?

    I'm really getting impatient ;)
