Hi Sourav,
If your WebSite is reachable using HTTPS (port 443), then data will be encrypted.
According to this doc : https://learn.microsoft.com/en-us/azure/data-factory/data-movement-security-considerations#encryption-in-transit
In hybrid scenario (non-Cloud -> Cloud) "All data transfers are via secure channel HTTPS and TLS over TCP to prevent man-in-the-middle attacks during communication with Azure services."
Therefore, even if in ADF you configure a pipeline using HTTP connector, this connector can read from both HTTP and HTTPS : https://learn.microsoft.com/en-gb/azure/data-factory/connector-http?tabs=data-factory#supported-capabilities
"You can use this HTTP connector to:
- Retrieve data from an HTTP/S endpoint by using the HTTP GET or POST methods."
Please let me know if this clarify your ask.
Thank you!
