ngrok makes it easy to securely connect to devices deployed in remote networks. Whether you need to reach a sensor behind a firewall, provide remote admin access to a kiosk, or connect your cloud to thousands of field-deployed devices, ngrok gives every device a secure, addressable endpoint. No firewall changes, VPNs, or open ports required.

​
Why use ngrok as a device gateway?

  • Every device gets a URL: Each device becomes addressable by your cloud, technicians, and customers without touching the remote network.
  • Policy lives in the cloud: Update access controls, authentication, and rate limits without firmware pushes or truck rolls.
  • No VPN required: Unlike a VPN, the ngrok agent connects outbound on port 443 and scopes access to specific services—not entire networks. No inbound ports, firewall rules, or network reconfiguration needed on the remote network.
  • API-compatible: Every feature and function is available via the ngrok http API so you can manage your entire fleet programmatically.
  • Pay only for what you use: On Pay-as-you-go plans, billing is per active endpoint hour. Spin endpoints up and down via API for security reasons, not cost ones.
