Project Turris is a service helping to protect its user's home network with the help of a special router. It is a not-for-profit research project of CZ.NIC, z. s. p. o., the registry of the Czech national top level domain .CZ.

About the project

The name of the Turris project is based on a latin word for tower - building often used to warn of approaching danger.

Each user of the service obtains a Turris router, which can, besides serving as a normal home router, also analyze the traffic between internet and the home network, and identify suspicious data flows. Similarly to a watchtower, it then alerts the Turris central of a possible attack. At the system headquarters, it is then possible to compare data from many connected Turris routers and asses the security status of detected traffic.

In case an attack is detected, corresponding updates are prepared and distributed to the whole Turris network, thus helping to protect all its users.

Due to the research nature of the project, we are offering the device for a symbolic price of one Czech crown. In order to participate in the project, the user is required to commit to using the Turris router as the main internet gateway for his network for a specified period of time, and not to intervene in collection of data.

Another possibility how to join the research is to preorder Turris Omnia. Turris Omnia is our new router which is built on experience we have got with the previous Turris routers and the Turris Project as a whole. It has much more recent hardware but uses the same operating system with automatic updates and other features. For more information check



Because we do not want to slow down your internet access by security analysis, we are developing our own high-performance hardware for the Turris router. It allows for protecting a home network without sacrificing transfer speed.


The Turris router contains a modern operating system with remote updates and an innovative system for security analysis of network traffic.


Enhancing security of your network is the main goal of our project. Besides the passive protection offered by a secure operating system, there is the additional benefit of distributed adaptive firewall.


Much attention was paid to protection of privacy and sensitive data. More information about specific measures is available on the linked page.


Openness is important for us. Therefore all the software running on the Turris router is released under a free license. In fact, even the hardware design is open.

The preregistration is not binding. We will use the registered e-mail address only for contacting you in case you are invited to take part in the project, or to inform you about important development of the Turris project.

or use
Do you have a validated mojeID? Great, you will be able to sign the contract online.

We will send you an invitation

In case you are selected, we will send you an invitation. Because the demand is higher than the number of routers available, you might not be selected. Once all available routers are released, we will inform the remaining preregistered users.


You will receive your router, plug it in and start using it

We will be ready to help you.
