About us

Who we are

We are a growing community of European information security professionals and privacy activists who like to share their knowledge for free. We started the “InfoSec Handbook” in January 2017. In March 2018, we decided to redesign/rename the website entirely and switched to English only. We reach a global audience and are in close contact with InfoSec professionals from all over the world.

We are not available for hire!

What we do

First of all, we are full-time employees working closely with many other information security experts every day. Our employers are well-known international companies, which are active in various InfoSec domains. Being active in distinct InfoSec domains ensures that our website covers a wide range of different InfoSec topics. Our professional daily work includes conducting penetration tests, analyzing malware, designing industrial networks, inspecting network traffic, hardening operating systems and applications, creating tools for particular tasks, writing InfoSec policies and guidelines, and much more. Kindly note that our families and principal employers have priority over our website.

We operate the non-profit (100% self-funded) InfoSec Handbook as a team, focusing on a privacy-friendly and secure design. We process the least amount of personal data possible to provide our website, and regularly reconfigure and closely monitor our web servers to ensure secure operation.

Besides, some of us conduct workshops and give lectures. For instance, we were at:

  • Vysoké učení technické (University of Technology) in Brno, Czech Republic
  • České vysoké učení technické (Czech Technical University) in Prague, Czech Republic
  • Universität Regensburg (University of Regensburg), Germany
  • Zentrum Digitalisierung.Bayern (Center for Digitalization Bavaria), Germany
  • IT-Cluster Linz, Austria

To acquire additional skills and meet with other professionals, we regularly attend security summits and workshops. You can meet us in person if you attend events like the Gulaschprogrammiernacht, BSides Munich, C3W PrivacyWeek, or Honeynet Project Workshops. 😉

Finally, we sometimes look for security vulnerabilities in websites/web applications/software and report findings to administrators/developers. As of May 2020, we sent reports to about 166 companies, organizations, and private individuals. We also privately report incomplete privacy policies; however, this isn’t the main focus of our voluntary work.

What we don’t do

As mentioned above, we do not promote any services or products of our employers on our website.

Since we like to read and write honest and neutral articles, we do not promote any services or products of companies, organizations, or private individuals in connection with sponsoring. For the same reason, we do not promote any services or products solely based on hearsay or assumptions.

Lastly, we do not contact the media or any other third party to share or sponsor our website or content.


All contributors are either information security professionals or privacy activists who want to share their knowledge with you for free.
