We can use secure+free MQTT (with SSL) (MQTTS). Like Flespi MQQT Broker and Adafruit MQTT Library. Additional information:

Altenartives:

• GCP IoT (has free tier up to 500mb/month)
• Amazon IoT - not free

There is TLS support/processor in only Wifi module (ESP8266) not in Ethernet module (ESP32) or shield (w5100). You can use TLS with 'WifiClientSecure' library (only for Wifi modules/shields) but could not use 'EthernetClient' library (There is no support for TLS). Flespi.io (with Adafruit MQ) supports TLS but in their sample code they used 'WifiClientSecure' structure.

What a disappointment!

We can have TLS over Ethernet on esp8266/arduino
