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 this blog in January 2017. In March 2018, we decided to completely redesign/rename the blog, and switched to English only. Due to this, 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 everyday. Our employers are well-known international companies, which are active in different InfoSec domains. This ensures that our blog 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 different operating systems and applications, creating tools for special tasks, writing InfoSec policies and guidelines, and much more. Kindly note that our families and principal employers have priority over our blog.
We operate this non-profit (100% self-funded) blog as a team, focusing on a privacy-friendly and secure design. This means that we process the least amount of personal data possible to provide our blog, 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. If you attend events like the Gulaschprogrammiernacht, BSides Munich, C3W PrivacyWeek, or Honeynet Project Workshops, you will probably meet one of us. 😉
Finally, we sometimes look for security vulnerabilities in websites/web applications/software, and report findings to administrators/developers. As of June 2019, we sent reports to about 87 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 blog.
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 media, or any other third party to share, or sponsor our blog, or content.
