Hi team, quick question about SSL/TLS. Outbound traffic from Edge/Stream to S3 is already encrypted, but we want to ensure inbound data sent to Cribl is encrypted if it may cross the internet.
  • Do we need to enable SSL/TLS on the Listener for inbound data in that case
  • Can Edge/Stream use a self‑signed certificate
  • If so, is adding that cert to the sender’s trust store the correct approach

Hi @user 1. Yes, enable TLS. Cloud provides an out of the box certificate for you to reference as a global variable 2. Yes, you may use a self-signed certificate as well. Be sure to include the full cert chain 3. Yes, you will need to add the CA certificate, used to sign the certificate chain, to the sender's trust store.
