Built into Jabber is a way of providing messages with protected Internet addresses of each user and a presence system that enforces a subscription model. It has always been designed to put the recipient in control of how to manage the data they receive, and the sender in control of what data they are sending. The Jabber Protocol hides the clients' IP address, so others can't spy into your machine.
Servers also use a dial-back system to ensure server identities.
Through the use of server and client-side filter, users have the ability to deny communications by user, domain, message type, or content. Another important security feature is the optional use of SSL to encrypt communications between the client and the server. In the future we hope to add support for PKI to ensure the identity of senders and prevent data tampering. For more details, read our technical whitepaper . Inc.
