# Security

Sanas is built with enterprise-grade security at every layer — from authentication to audio transmission.

## Network Security

All communication between the SDK Connector and Sanas Cloud uses SIP for connection establishment and RTP for audio streaming. See [Sanas Cloud deployment](/Docs/Deployment/Sanas-Cloud) for firewall and network configuration details.

## Encrypted Audio Transmission

Enable encrypted media transport by setting `secureMedia = True` during SDK initialization. All audio is encrypted in transit between the SDK Connector and Sanas Cloud.

```python theme={null}
init_params.secureMedia = True
```
