Dresdner is a popular alternative for corporations that cannot afford a full-time security force. They are generally considered the "budget" alternative compared to services like Taikun and Nakura.
The Dresdner Security Bot is a rental security robot. Not state of the art. It has lots of sensors for smells, sounds, etc.
Through some shady backroom deals, Dresden Outsource Security Services was able to get a 5-year exclusive contract for security at all E-Mart superstores. Dresdner stands to make a huge profit in the long term, if no one interferes.
