ZeroTier

ZeroTier builds software for creating secure virtual networks between desktops, mobile devices, servers, cloud machines and embedded hardware. It joins the roles of a VPN and SD-WAN in a single tool. Every endpoint checks its peers and enforces policy itself, so there is no central box to attack.

What ZeroTier offers

• Peer-to-peer virtual networks — private links for distributed teams and remote devices.
• Layer 2 Ethernet emulation — multipath, multicast and bridging features.
• Cloud backplane — one network that spans several cloud providers and on-premises sites.
• Access management — remote access for staff, contractors and partners that can be granted or removed easily.
• Quantum-safe networking — a newer platform using post-quantum algorithms from the CNSA 2.0 suite, including options for air-gapped sites.

Who it works with

Regulated organisations, government bodies, manufacturers and robotics firms, IoT builders, and home users who reach their own devices remotely.
