What is zerotier.exe?

zerotier.exe is the Windows executable for ZeroTier One, a software-defined virtual network that forms secure, peer-to-peer overlays. It manages membership, relay candidates, and route discovery, enabling devices to join private networks regardless of underlying topology. It runs continuously to sustain connections even when idle.

ZeroTier uses a lightweight daemon to manage virtual networks, peer connections, and route discovery. It runs in user space and communicates with centralized controllers to form secure overlays across devices and networks.

Quick Fact: ZeroTier started as an open-source project and provides a turnkey overlay network that works across routers and NATs.

Types of ZeroTier Processes

Is zerotier.exe Safe?

Yes, zerotier.exe is safe when it's the legitimate file from ZeroTier, usually downloaded from zerotier.com or installed via official channels.

Is zerotier.exe a Virus or Malware?

The real zerotier.exe is NOT a virus. Malware may masquerade with similar names to mislead users.

How to Tell if zerotier.exe is Legitimate or Malware

  1. File Location: Must be in C:\Program Files\ZeroTier\One\ZeroTier One.exe or C:\Program Files (x86)\ZeroTier\One\ZeroTier One.exe. Any zerotier.exe elsewhere is suspicious.
  2. Digital Signature: Right-click the process in Task Manager → Open file location → Right-click ZeroTier One.exe → Properties → Digital Signatures. Should show "ZeroTier, Inc."
  3. Resource Usage: Normal usage is 0-4% CPU per process, 20-60 MB total memory. Extremely high usage when not operating is suspicious.
  4. Behavior: ZeroTier should run as a background service and only engage when a virtual network is active. Constant activity when offline is suspicious.

Red Flags: If zerotier.exe is located in unusual folders (like Temp, AppData, or System32), runs without user action, lacks a valid signature, or uses constant high resources, scan with antivirus. Be wary of similarly-named files like "zer0tier.exe" or "zt-one.exe".
