How Do I Terminate TLS?

You can configure TLS termination for HTTPS, TCP, and TLS endpoints with ngrok. By default, ngrok automatically terminates TLS for HTTPS endpoints, but you can still customize how that termination is done using the terminate-tls Traffic Policy action.

TLS (SSL) certificate management is automatically handled for you by default for all endpoints, though you can also bring your own TLS certificates.

How is TLS terminated by default?

An endpoint's protocol determines the ngrok cloud service's default TLS termination behavior.

Endpoint Protocol	TLS Termination
HTTP	None
HTTPS	Always at ngrok's cloud service.
TLS	Default no termination, configurable with terminate-tls
TCP	Default no termination, configurable with terminate-tls

Using terminate-tls

Visit the Traffic Policy docs to see examples using the terminate-tls action.

• Using Traffic Policy — The terminate-tls Traffic Policy Action enables you to terminate TLS connections at ngrok's cloud service for TCP and TLS endpoints.
• Behavior — Learn about how ngrok's TLS termination works, and how its built-in optimizatiions can improve the performance of your TLS endpoints.
• Certificates — ngrok makes managing TLS certificates simple. See the TLS Certificates documentation for more details on how they are selected, managed, provisioned and renewed.
• End-to-end encryption — Enabling end-to-end encryption for TLS endpoints is straightforward. See the docs on how TLS termination works to learn more.

Limits & pricing

TLS endpoints are available on Pay-as-you-go, Pro, and Enterprise plans. Consult the pricing documentation for general billing details.
