Christian Mainka completed his doctorate in 2017 on the topics of web services and single sign-on.

Since 2009, he has been working on security aspects resulting from the use of data description language such as XML. He developed the first web service-specific penetration test tool WS-Attacker. Since then, he has been constantly improving and extending the program so that it can now detect fully automatically a broad spectrum of known vulnerabilities on web services. In his dissertation "On Message-Level Security" he also analyses the security of modern single sign-on procedures such as SAML, OAuth and OpenID Connect and uncovered numerous security gaps.
