Payload/Message Encryption in Azure Signalr Service related Information

Question

Does Azure SignalR service have visibility of the messages that it channels?
Does the Payload encryption of the messages take place at the Application server end or can something be configured at the Azure SignalR service ?
From the documentation - "SignalR Service does not save or store customer data, all customer data received is transmitted to target server or clients in real-time."
Azure Signalr service acts as a data processor - so the data is not stored not even in memory?
Please can you advise.

@Banerjee, Somdutta Thank you for reaching out to Microsoft Q&A. Based on your questions I have checked with internal team on this and below is the feedback.

1. Does Azure SignalR service have visibility of the messages that it channels?
   Yes. It’s “visible” to the Service and handled at service-level.
2. Does the Payload encryption of the messages take place at the Application server end or can something be configured at the Azure SignalR service ?
   *The encryption is done by the TLS. It’s in transport layer. *App Server -->(tls) Azure SignalR -->(tls) Customer’s Clients**
3. From the documentation - "SignalR Service does not save or store customer data, all customer data received is transmitted to target server or clients in real-time."
   Azure Signalr service acts as a data processor - so the data is not stored not even in memory?
   It’s stored in memory. But not persistent to disk.

Feel free to reach back to me if you have any further questions on this.
