Today the Tor Project, a global non-profit developing tools for online privacy and anonymity, and Tails, a portable operating system that uses Tor to protect users from digital surveillance, have joined forces and merged operations. Incorporating Tails into the Tor Project's structure allows for easier collaboration, better sustainability, reduced overhead, and expanded training and outreach programs to counter a larger number of digital threats. In short, coming together will strengthen both organizations' ability to protect people worldwide from surveillance and censorship.
Pooling resources to better serve a global community
Countering the threat of global mass surveillance and censorship to a free Internet, Tor and Tails provide essential tools to help people around the world stay safe online. By joining forces, these two privacy advocates will pool their resources to focus on what matters most: ensuring that activists, journalists, other at-risk and everyday users will have access to improved digital security tools.
In late 2023, Tails approached the Tor Project with the idea of merging operations. Tails had outgrown its existing structure. Rather than expanding Tails’s operational capacity on their own and putting more stress on Tails workers, merging with the Tor Project, with its larger and established operational framework, offered a solution. By joining forces, the Tails team can now focus on their core mission of maintaining and improving Tails OS, exploring more and complementary use cases while benefiting from the larger organizational structure of The Tor Project.
This solution is a natural outcome of the Tor Project and Tails' shared history of collaboration and solidarity. 15 years ago, Tails' first release was announced on a Tor mailing list, Tor and Tails developers have been collaborating closely since 2015, and more recently Tails has been a sub-grantee of Tor. For Tails, it felt obvious that if they were to approach a bigger organization with the possibility of merging, it would be the Tor Project.
"Running Tails as an independent project for 15 years has been a huge effort, but not for the reasons you might expect. The toughest part wasn't the tech–it was handling critical tasks like fundraising, finances, and HR. After trying to manage those in different ways, I’m really relieved that Tails is now under the Tor Project’s wing. In a way, it feels like coming home."
–intrigeri, Team Lead Tails OS, The Tor Project
Welcoming new users and partners into our communities
Whether it’s someone seeking access to the open web or facing surveillance, Tor and Tails offer complementary protections. While Tor Browser anonymizes online activity, Tails secures the entire operating system–from files to browsing sessions. For journalists working in repressive regions or covering sensitive topics, Tor and Tails are often used as a set to protect their communications and safeguard their sources. The merger will lead to more robust treatment of these overlapping threat models and offer a comprehensive solution for those who need both network and system-level security in high-risk environments.
It will also open up broader training and outreach opportunities. Until now, Tor’s educational efforts have primarily focused on its browser. With Tails integrated into these programs, we can address a wider range of privacy needs and security scenarios. Lastly, this merger will lead to increased visibility for Tails. Many users familiar with Tor may not yet know about Tails OS. By bringing Tails within the Tor Project umbrella, we can introduce this powerful tool to more individuals and groups needing to remain anonymous while working in hostile environments.
"Joining Tor means we’ll finally have the capacity to reach more people who need Tails. We've known for a long time that we needed to ramp up our outreach, but we just didn’t have the resources to do so"
–intrigeri
"By bringing these two organizations together, we’re not just making things easier for our teams, but ensuring the sustainable development and advancement of these vital tools. Working together allows for faster, more efficient collaboration, enabling the quick integration of new features from one tool to the other. This collaboration strengthens our mission and accelerates our ability to respond to evolving threats."
– Isabela Fernandes, Executive Director, The Tor Project

Highlights
In August:
We continued making it easier for Tails users to recover from the most common failure modes:
we released the first iteration of our design to detect a partition table corruption and advise users about it.
we worked on implementing detection of the Persistent Storage corruption on a Tails USB stick, reporting it to users, and repairing it.
We resumed our work to design a better backup feature for the Persistent Storage. We integrated the valuable feedback received in July on our design proposal for the improved backup feature (mockups on Gitlab).
We published instructions for installing Dangerzone in Tails. Dangerzone will help Tails users convert suspicious documents to safe PDFs. This was a significant milestone: this is the first time that we have recommended installing a 3rd party package that is not available in Debian.
Releases
In Tails 6.6, we brought:
improved hardware support for graphics, WiFi etc.
an updated Tor Browser and fixed issues with connecting to the Tor network using default bridges

Highlights
On our first month back from vacation, we continued making it easier to recover from common failure modes without requiring technical expertise:
we drafted an implementation of our design to detect, report, and repair corruption of the Persistent Storage
we finished implementing our plans to improve the detection of and recovery from low-memory situations. Going from prototype to implementation, this work was a great example of the 90-90 rule in action: the first 90% of the work consumed the first 90% of our time, and the remaining 10% accounted for the other 90% of our time
Over the past year, we have been close downstream of the Tor Project's design and implementation of Arti. This month, we reached a significant milestone in our collaboration: we prepared a prototype of Tails in which multiple applications use Arti.
freiheitsfoo, one of our longest supporters, renewed their sponsorship of Tails! Welcome aboard for another year of resisting censorship and surveillance online!
Releases
In Tails 6.5, we brought:
an updated Tor Browser with cool letterboxing improvements, and the latest Debian (12.6)
repairs to first-boot partitioning that many users were facing issues with after Tails 6.4
fixes to connecting via mobile broadband, LTE, and PPPoE DS. This has been a persistent issue in the Tails 6 series so far.

Today, we added documentation on our website to install Dangerzone in Tails.
When you receive untrusted documents, for example, email attachments, Dangerzone allows you to convert them into safe PDFs before opening.
Dangerzone is particularly useful for journalists who might receive dangerous documents from anonymous sources or download them from the Internet.
Dangerzone is an essential tool and is built by great people. It was first written by Micah Lee to protect investigative journalists while working at The Intercept. Dangerzone is now maintained by Freedom of the Press Foundation, a non-profit that protects public-interest journalism. Edward Snowden and Laura Poitras are on its Board of Directors.
It's totally the kind of software that aligns with our mission. The only reason why we are not including Dangerzone in Tails by default is because Dangerzone is too big and not available in Debian.
So, we collaborated with Alex Pyrgiotis from Freedom of the Press Foundation to make it as easy as possible to install Dangerzone in Tails as Additional Software. The setup requires using the command line, but, after that, Dangerzone will install automatically every time you start Tails.
Dangerzone will allow more investigative journalists to use the safe environment that Tails provides when manipulating sensitive documents.
It's also the first time that we recommend installing a 3rd party package that is not available in Debian. We know that a lot of software that would be useful for our users is not readily available in Debian. If this first experiment is successful, we might document more such packages.
Changes and updates
Make installation with Tails Cloner 30 seconds faster. (!1588)
Update Tor Browser to 13.5.1, including improved letterboxing.
Update Debian to 12.6.
Fixed problems
Fix preparation for first use often breaking legacy BIOS boot and creation of Persistent Storage. (#20451)
