Issues * If end-to-end security is required, a protocol like WS-SecureConversation may reduce the overhead. * The merging of several XML-schemata like SOAP, SAML, XML ENC, XML SIG might cause dependencies on different versions of library functions like canonicalization and parsing, that are difficult to manage in an application server.

Performance
WS-Security adds significant overhead to SOAP-processing due to the increased size of the message on the wire, XML and cryptographic processing, requiring faster CPUs and more memory and bandwidth.
An evaluation in 2005 [1] measured 25 types of SOAP messages of different size and complexity processed by WSS4J with both WS-Security and WS-Secure Conversation on a Pentium 4/2,8 GHz CPU. Some findings were: * Encryption was faster than signing * Encryption and signing together were 2-7 times slower than signing alone and produced significantly bigger documents. * Depending on the type of message, WS-Secure Conversation either made no difference or reduced processing time by half in the best case. * It took less than 10 milliseconds to sign or encrypt up to an array of 100 kilo bytes, but it took about 100~200 to perform the security operations for SOAP.
Alternative
In point-to-point situations confidentiality and data integrity can also be enforced on Web services through the use of Transport Layer Security (TLS), for example, by sending messages over https. WS-Security however addresses
