Since 2004, Marcel Waldvogel is Professor of Computer and Information Science at University of Konstanz, Germany and has been head of the University’s IT Infrastructure Centre and later a director in the University’s Communications, Information, Media Centre for over a decade. Before that, he worked on innovative networking technologies at IBM’s Zurich Research Laboratory in Rüschlikon, Switzerland. He also was Assistant Professor at Washington University in St. Louis, Missouri, USA and had co-founded a successful software development and consulting company. He holds a Diploma degree in Computer Science (Informatikingenieur) and a Ph.D. from ETH Zürich and has authored approximately 100 scholarly publications.

This unique combination of innovative research and pragmatic implementation is a guarantee for novel, down-to-earth solutions. By exploring all degrees of freedom, he continually challenges himself to provide a lean solutions, exceeding your expectations in security and effectiveness. This has helped many users, ranging from global players in networking technology to security-conscious medical institutions.

Securing the Internet

According to an old proverb, security is a process, not a goal. The entire IT team from software developer, system administrator up to the management, need to be aware of this. Your entire IT staff needs to defend hundreds or thousands of potential risks, while an attacker is full of joy once he finds a single loophole.

Our increasingly diverse infrastructure for home and business use makes this defense harder and harder every day. Security is the fine line to walk while at the same time making all information easily accessible to all authorized users with imperceptible hurdles from all around the world on all kinds of devices; while at the same time creating impenetrable walls and moats against potential intruders.

To make security manageable, the different devices and applications from various vendors should be easy to manage. Ranging from

  • cyber-physical systems (CPS) in business environments (plant controls, building management etc.) over
  • home-level Internet-of-Things (IoT) devices including thermostats, oven controls, or security cameras to
  • web applications accessed from remote Internet cafés,

the threats are overwhelming, especially as vendors even on the same platform rarely obey to standards or provide fast responses to security problems.

My research provides a three-pronged approach at solving security threats:

  1. Create a generic application security manager, which takes existing, unmodified applications and hardens their security settings. This is based on our work on TLS Interposer.
  2. Provide new, general, low-overhead and user-friendly ways for two-factor authentication to sensitive web applications, again without the need to modify the application. This will use technology from our TLS Interposer and opDNS security research.
  3. Secure Wireless Personal Area Network (WPAN) and IoT devices by ensuring they communicate only securely with pre-defined devices. Our goal here again is to minimize the changes necessary to existing applications and devices.


Netfuture is where Marcel Waldvogel talks about the future of Internet technology, focusing on security and scalability in a growing Internet world. Those needs can often be best achieved by decentralized or federated solutions based on open, peer-reviewed protocols. To get these services to users, a comfortable web-based user experience is one of the key aspects.

This expertise is provided to help you provide bespoke innovative solutions featuring elegant simplicity and high practical value to the growing needs of security and privacy.
