About us

Who we are

We are a group of European information security professionals and privacy activists who like to share their knowledge for free. We started this blog in January 2017. In March 2018, we decided to completely redesign/rename the blog, and switched to English only. As of March 2019, more than 6,000 people follow us on different social networks.

This blog isn’t related to our employers. All statements are our personal, professional opinion. We are not available for hire.

What we do

  • We operate this ad-free, privacy-friendly, and secure blog (infosec-handbook.eu)
  • We conduct workshops at different universities in the Czech Republic (Vysoké učení technické (University of Technology) in Brno, and České vysoké učení technické (Czech Technical University) in Prague, Czech Republic)
  • We give lectures at different universities in the Czech Republic and in Germany (Vysoké učení technické (University of Technology) in Brno, Universität Regensburg (University of Regensburg))
  • We present security topics to different target groups at different locations (e.g. Zentrum Digitalisierung.Bayern (Center for Digitalization Bavaria), IT-Cluster Linz)
  • We meet with other professionals to exchange ideas, and knowledge about information security
  • We sometimes look for security vulnerabilities in websites, web applications, or software, and report findings to administrators/developers. As of March 2019, we sent reports to about 45 companies, organizations, and private individuals.

What we don’t do

  • We do not promote any services or products of our employers on our blog
  • We do not promote any services or products of companies, organizations, or private individuals in connection with sponsoring
  • We do not promote any services or products solely based on hearsay, or assumptions
  • We do not process any personal data that isn’t technically needed to operate our blog securely, or to deliver our content to your device
  • We do not contact media, or any other third party to share, or sponsor our blog, or content
