Turris Shield⚓︎

Turris Shield

Turris Shield is a single-purpose device for everyone who wants to easily secure their entire home or office without having to change their modem or router.

Hardware-wise it is based on Turris MOX. The main difference is software and target audience. While MOX is trying to be as customizable as possible, Shield on the other hand tries to be as simple as possible while still being secure.

Software⚓︎

Turris Shield comes with Turris OS with several important tweaks by default. Setup guide is simplified to just entering your password which is immediately offline (without ever leaving the router) checked against the list of passwords collected from recorded attacks. From that moment onward, you are good to go and can connect to the Internet.

Turris Shield is also the first device to feature reForis user interface by default. It does not contain LuCI nor Foris. Automatic updates are enabled by default as is Turris Sentinel – key feature of Turris Shield.

Other features readily available include support for DNSSEC, OpenVPN (both server and client) or for example automatic notification of newly connected devices. Shield contains the NetMetr application too.

Shield vs. MOX⚓︎

Although Shield is based on MOX, there are some substantial differences between them:

  • Shield cannot be extended by additional modules. Eventually added modules cannot cause hardware damage but will not work due to missing software support. It is also not possible to replace the current C module (4x Ethernet) by any other module.
  • Shield uses some “magic” to determine the best address range on the LAN. This is intended to avoid address collisions becase the given situation is more prone to them. Additionally, Shield always listens on 192.168.1.1.
  • Shield has modified rescue modes. Because of simplified setup, the default is to reset to the factory state. See Rescue modes for more information.
  • Only one setup type. Shield supports only the router setup. It means that the WAN socket is connected to the uplink (with support for PPPoE) and the four LAN sockets are downlinks (with IPv4 NAT and IPv6 DHCPv6 prefix delegation).
  • No support for guest networks. There is no Wi-Fi adapter and the purpose of Shield is different than building complex networks.
  • No port forwarding nor custom firewall rules. These features are out of the scope of Shield.
  • Automatic updates are always enabled and not configurable. There is no reason to disable or delay automatic updates which are one of the key security features.
  • Additional software is not supported. While MOX supports a wide range of installable software, Shield is intended to be as simple as possible and any additional software could lead to potential problems, e.g. with memory or CPU power.

We recommend to buy Shield if you want the simple device that just works out of the box and is easy to setup. If you want more features, custom network setup and additional opensource software, take a look at MOX or Omnia.
