+Redis doesn't support TLS natively, however if the redis server you want to connect to is hosted behind a TLS proxy (e.g. [stunnel](https://www.stunnel.org/)) or is offered by a PaaS service that supports TLS connection (e.g. [Redis Labs](https://redislabs.com/)), you can set the `tls` option:
+

+var redis = new Redis({

+  tls: {
+    // Refer to `tls.connect()` section in
+    // https://nodejs.org/api/tls.html
