We love to share our knowledge
We are not standard corporate trainers reading from a pre-packaged syllabus. Our courses are designed and delivered by the same senior engineers, active kernel maintainers, and cryptographers who build real-time systems and audit complex architectures.
With over 20 years of hands-on experience, a track record of upstream kernel patches, and real vulnerability discoveries, we bring real-world battle scars into the classroom. We offer both standard modules and deeply customized, long-term in-house engagements tailored to your stack.
Core Training Modules
Embedded Linux & Kernel Engineering
We teach your team how to build, optimize, and maintain robust Linux systems.
Applied Security & OS Hardening
Turning your administrators and engineers into security-first operators.
Secure Coding & Engineering Practices
Equipping your developers to write secure, maintainable code from day one.
Explore our trainings
Not sure which format fits? Our recurring trainings are scheduled, ready-to-book courses on proven topics like Yocto, kernel internals, and secure coding, taught in small groups so your team can upskill quickly on a known subject. Customized trainings work the other way around: you choose the topics and we build them around your codebase, stack, and goals, delivered in-house, from a one-day session to a five-day deep dive.
How We Solve Training Challenges
"Our developers keep introducing the same memory corruption vulnerabilities in our C/C++ backend."
We deliver a customized Secure Coding Training. We use sanitized examples from your actual codebase to teach your team how to avoid these specific pitfalls.
"Our systems administrators instinctively disable SELinux because it breaks our applications."
We run our SELinux & Linux OS Hardening Training. We demystify the technology and teach your team how to write, debug, and maintain strict access policies without halting production.
"We are transitioning our hardware to a Yocto-based build system and our engineers are overwhelmed."
We deploy our Embedded Linux Training. A kernel maintainer sits down with your team, demystifies the build recipes, and helps set up a reproducible build environment.
Your Benefits
We do not just teach behind closed doors. We actively shape the global engineering and security communities and regularly present our research, toolkits, and kernel contributions at premier conferences, from the Embedded Linux Conference and Open Source Summit to LinuxTage Graz and BSides Munich.
Time to team up
Your engineering team lacks some knowledge or skills we can provide? We offer honest, highly technical training, both as standard modules and as deeply customized in-house engagements. Let’s team up and level up your team.
