Current challenges on the markets cause companies to interact with one another and strive after becoming members of virtual organizations assuming that in doing so they can achieve sustainable competitiveness and remain successful despite increased competition.

The presented approach aims at minimizing the leadtime before usage of external services can start by employing a security intermediary for mediation purposes.
