About me

Digital Bodyguard

In a company, it's the IT department and the Chief Security Officer who are responsible for the security of the digital world.
In real life, people surround themselves with bodyguards to protect their life and well-being. Important documents are kept in a safe or bank vault.

But where do we keep our documents on the world wide web? And who protects our digital identity when we're on social media?
As a digital bodyguard I take care of your personal digital presence, from safe data storage to controlled communication on social media.

Linkedin and Twitter are famous tips of the proverbial iceberg - platforms, whose password databases have been leaked. This topic has made the headlines since they're well-known. How well are we aware that the databases published today are the result of hacks from 2012 (e.g. Dropbox) and earlier? This topic is still relevant in this day and age and new famous names are continuously added to this Hall of Shame (see Wikipedia).

Soon 2020 is over, criminality is taking place more and more often online, the Covid-19 movement restrictions have played a significant part in this. Apart from protecting your own accounts, you also have to be on guard more than ever. Fake profiles, fake news - the number of “fakes” has been skyrocketing. And talking about your social media accounts: a good reputation is highly attractive to those who want to spread fake news.

You might as well don't care about it.

• You have no social media profiles.
• You don't use any cloud storage (Dropbox, OneDrive, iCloud Drive etc.).
• You use your phone exclusively for making phone calls.
• You don't have any data that could interest anyone.
• You don't have any accounts that someone could misuse.
• Your antivirus software gives you anyway all-round protection.

Are you still with me and you're concerned about the safety of your digital existence?

Business Angel

In 2018 I started considering the idea of becoming a business angel.

This role is commonly described using the definition of smart money, i.e. financial investment in a start-up with the added expertise and experience that a business angel brings to the table.

I have also found out what my role is: as a business angel, I buy myself work.
I put effort into it in the hope that I will eventually be rewarded through the appreciation in value.

Apart from my expertise in the field of IT security, I also offer my support in all things strategy and structure. After all, as a serial entrepreneur I can draw on a vast repertoire of failures.

From my experience, a start-up is characterized by a heavily shifted balance between technology and sales. A strong sales team can boost sales, but the lack of fulfillment leads to bad reputation, rescissions or similar economic setbacks or blocks in the long run. If one starts out with a strong technical team, they usually lack a vital pipeline. Hope is always to find in the next opportunity. The client is anyway very interested and fully enthusiastic.

Some samples from my investment portfolio

This instrument created to be used as an Open Source Investigation Tool (OSINT) is a highly specialized solution, able to save and visualize networks in graphs and simultaneously provide a broad variety of potential other applications.

KIVU managed to find a tech-based solution, namely to calculate and visualize a network of many highly interconnected nodes. KIVU’s algorithms manage to do that within seconds, enabling the eye to switch on the interconnection between the nodes in order to highlight certain aggregations within the network.

To be available for the customer. That is why service-centered business models are increasingly popular and being available has become a competitive factor even for small businesses.

At the same time, a business must keep an eye on the budget. To keep phone costs to a minimum, they make use of IVR systems. And even today, it beats me what is so service-centered and customer-friendly at this type of system (‘Press 1 for…’).

At the other end of the spectrum, there is the friendly voice from Yodel that asks customers about their issues and lets them tell their story. If it can find an answer to that specific issue in the transcripts, the voice can give them an answer right away, ask further questions or send them to the next support level (Slack, Teams, call center…).

I am indirectly involved in Yodel through the EXF Alpha S.C.S fund of the European Super Angels Club (ESAC).


I have been working with Klaus Thurnhofer on various IT and service assignments for years. Klaus Thurnhofer is a very considerate, customer-oriented specialist, whose work is always solution-oriented and very precise. For these reasons, I can highly recommend Klaus Thurnhofer in his areas of expertise.

Mr. Thurnhofer speaks an IT-language that I can understand. His tips and suggestions are easy to implement. Compared to other IT consultants, his proposed solutions are exceptional and custom-made for each user. He focuses more on his clients and their needs, as well as on their personal problems (personal habits and challenges in the IT world). He then finds simple and feasible solutions and sets everything up in such a way that the user can take care of it well, easily and safely, with no further assistance.
In spite of his comprehensive expertise and professional competence, you don't feel overwhelmed or exhausted by his advice. You don't feel the need to get a second opinion. Klaus gives the client the feeling of being presented with a sensible solution - nothing exaggerated, unnecessary or sales-oriented or solutions in which one does not want to invest because your gut feeling doesn't approve.
GREAT advice!
