The BizTalk Server depends mainly on security provided by certificates and uses them for encryption and digital signatures. By using certificates for encryption and digital signatures, The BizTalk Server can:
Send and receive data that can be trusted
Make sure that the data it processes is secure
Make sure that the authorized parties receive its messages
Make sure that it receives messages from the authorized parties
