HTTPs (Hypertext Transfer Protocol Secure) is a secure extension of the HTTP protocol. It establishes a secure connection between a web browser and a web server, protected against eavesdropping or tampering. HTTPs can also include authentication of the remote side.

In the context of NETIO products
- Linux based devices (PowerPDU 4C only) can be configured to support https (web interface).
-
For the configuration (web interface), a HTTPS port different from the HTTPS port for M2M protocols can be used; see the product configuration.
However, in this case all M2M protocols based on HTTPS share this other port for M2M communication. - Some M2M APIs use HTTPS. This concerns in particular the REST protocols – XML and JSON. For these protocols, HTTPS is a good choice in terms of security and standards.
- HTTPS is also used by the M2M URL API, which is a simple protocol to switch socket states by accessing a URL e.g. from a web browser.
Custom HTTPs Certificates
Since PowerPDU 4C firmware v. 3.4.3 is possible to save a custom certificate in the regular version of the product.
HTTPs support in other NETIO devices
- Other NETIO devices than PowerPDU 4C do not support HTTPs today (spring 2023).
- There is SSL available for MQTT / NETIO Cloud communication
- There is part of HTTPs implemented as part of Push protocol.
