Preparing to configure TLS optimization
The license for TLS optimization also activates data store encryption and enables the appliance to create secure channels while optimizing encrypted MAPI and SMB-signed traffic, even if the appliances aren’t configured for optimizing SSL traffic.
1. Connect to the Management Console using HTTPS to protect your SSL private keys and certificates.
2. On the client-side and server-side appliances, ensure you have a valid Enhanced Cryptography License Key or SSL/TLS Optimization license. To verify your license, see Managing licenses and model upgrades. If you don’t have a valid Enhanced Cryptography License Key or SSL License, go to Knowledge Base article S28361 for instructions on how to get one.
3. Back up your private keys and CA-signed certificates.
