Especially when a critical market event occurs much depends on processing the informa- tion efficiently and in time. Mobile information services may then improve the information supply for these investors. In this contribution we will determine which financial information services are suitable for mobile use and show what kind of improvements the use of this technology will provide. We take a look at the potential benefits of mobile financial information pull and push services and also determine the security requirements of such services com- paring them with what current technology has to offer. It shows that none of the technologies used today is able to provide the support for all the stated se- curity requirements and that at least three areas would profit from certifica- tion.
