### Social/Discovery
Built-in information about network availability (“presence”)
Presence subscriptions for two-way authorization
Presence-enabled contact lists (“rosters”)
XMPP includes the ability for users to advertise their network availability or "presence." This is not strictly necessary for the exchange of data, but facilitates real-time interaction by indicating the the recipient is online and available. Users can subscribe to each other's presence statuses.
XMPP includes the ability for users to advertise their network availability or "presence." This is not strictly necessary for the exchange of data, but facilitates real-time interaction by indicating the the recipient is online and available.
Users have contact lists called "rosters". Rosters are [often stored on the server](https://www.blikoontech.com/tutorials/xmpp-made-simple-roster-and-presence-explained) to protect the user's social graph.
### Privacy/Access Control
Channel encryption using Transport Layer Security (TLS)
Strong authentication using the Simple Authentication and Security Layer (SASL)

The original protocol did not include end-to-end encryption by default. Encryption methods were later added as extensions to the core protocol.
XMPP includes a method for authenticating a stream using the [Simple Authentication and Security Layer (SASL)](https://tools.ietf.org/html/rfc6120#ref-SASL).
