# Activate TLS inspection on NGFW Engines

Depending on the elements you select in the engine properties, you can activate client protection alone, server protection alone, or client and server protection together.

##

CAUTION:

Uploading TLS Credentials or a Client Protection Certificate Authority elements to the engine might enable decryption of TLS traffic that is not excluded from TLS inspection. The following configurations might enable decryption of TLS traffic:

- Adding a Network Application that allows or requires the use of TLS to an Access rule
- Selecting the Enforced option for Log Application Information in the Access rules
- Enabling Deep Inspection in an Access rule if the Service cell contains a Network Application or a Service that does not include a Protocol Agent
