Tailor-made security training bites

Not every security problem calls for a full training program. Sometimes your team hits a specific gap: a vulnerability class that keeps showing up in code reviews, a new technology nobody on the team has secured before, or an architecture decision where the security implications aren’t clear. That’s what Custom Focus Sessions are for. I build a short, focused session around exactly the topic your team needs, based on a brief scoping call beforehand.

What kind of topics work well

Each engagement starts with a short call where we figure out what your team actually needs. No generic slides, no material recycled from other trainings. Here are some examples of what teams typically ask for:

Closing a specific knowledge gap
Maybe your developers are solid on web security but haven’t dealt with API authorization patterns, or they’re moving to a new framework and want to understand its security model before writing production code. A focused session can get the whole team to the same level in an afternoon.
Going deep on a single technique or area
Custom deep dives I covered in the past include GraphQL, gRPC, WebSockets, Spring Boot, React Native, CORS, Content Security Policy, Kubernetes hardening, cryptographic pitfalls in a particular language, supply-chain risks, and even domain-specific formats such as HL7/FHIR in healthcare. If your topic isn’t on this list, that’s perfectly fine and expected. Most sessions focus on something specific to a team’s stack that doesn’t fit neatly into a standard catalog. — This highly tailored session is shaped around the topics that matter most to your team. Every session is individually prepared (including full slide decks and sometimes even live demos) to match your team’s needs.
Securing AI-powered systems
Understanding and mitigating risks around LLM integrations, RAG pipelines, MCP tool use, and agentic AI architectures. This area moves fast, and most teams I talk to have more questions than answers when it comes to securing their AI features.
Securing AI-based coding workflows
More and more teams use AI coding assistants and agents that generate code, run shell commands, or interact with APIs on behalf of developers. That raises real questions: What can these agents access, what guardrails are in place, and how do you prevent them from introducing vulnerabilities or leaking secrets? This session covers the security boundaries around tools like Copilot, Codex, Claude Code, Cursor, and similar agents, so your team can use them confidently without opening up new attack surface or introducing new vulnerabilities in the codebase.
Reacting to something that came up
A penetration test found issues your team doesn’t fully understand yet, a new dependency introduced unexpected attack surface, or a security incident raised questions that need proper answers. These sessions work well when there’s a concrete trigger and the team wants to learn from it.

How the sessions work

Sessions run between 2 and 4 hours, depending on the topic. That’s long enough to get into real depth for a focus topic, short enough to fit into a workday without losing people’s attention or binding the team for too long.

I prepare every session individually. There are no pre-built modules I pull from a shelf. The content matches what came out of our scoping call, down to the specific tech stack, language, and architecture your team works with. Where it makes sense, I include interactive elements using Workshop Board so participants stay engaged rather than passively watching slides. Sometimes I even include live demos to show how to exploit vulnerabilities or how to secure a particular feature.

Remote delivery with recording option

All sessions run remotely via video call, so there’s no travel overhead on either side. If you want, I can record the session so your team can revisit the material later. Over time, several of my clients have built up their own internal library of these recordings. New team members get instant access to focused, relevant security training from day one, without having to wait for some next scheduled session.

Get started

If you have a specific security topic on your mind, get in touch and we’ll set up a short scoping call to figure out the right session for your team.

just one word: AWESOME! thank you!

Training Participant

Yes!! This should be mandatory for all software developers!

Training Participant

I would buy it again 5/5 stars :D

Training Participant

Great session Christian!!! Thanks a million!!!

Training Participant

It was great! Concrete examples, explained clearly — definitely left a lasting impression. Keep it up!!

Training Participant

The training made it tangible how hackers work in practice and which tools they have at their disposal. The concrete examples helped a lot.

Training Participant

I found the training comprehensive, VERY educational, highly interesting and exciting — and it really drives the point home. Remote participation was especially important for our team, and you mastered that format really well. The training had a clear narrative arc and clear business value. I’ll definitely recommend it. Thank you!

Training Organizer

Really, really well done pentesting lecture. It was very informative and fun to learn about this stuff again. Since becoming a developer I stopped coding in my free time, but seeing how to break systems — and how and why they work — was part of why I became a programmer in the first place. So the child in me was so happy to learn about XML bombs and all the other crazy things!

Training Participant

Much was new to me (even after years in corporate IT). With the flood of attack possibilities, the framework with “code/data” and “source-taint-sink” is helpful, as is the calm delivery and “let them discover” approach. I recommend the training!

Training Participant

First of all: thank you for an excellent workshop. Feedback on the second part of the workshop was consistently positive. I’ve already heard from several teams that they want to use threat modeling in practice going forward. From my perspective, a complete success.

Workshop Organizer

Very entertaining, interesting and inspiring two days of security training. Enjoyed it a lot and got curious about analyzing our code for weaknesses. Long live the Swiss cheese model! :-)

Training Participant

Thanks for the training. It was an eye-opener, especially the live hacking demonstrations.

Training Participant

Yes, it was really fun, especially the vivid way knowledge was conveyed, the practical examples, addressing every question, the detailed handout, and not least the pleasant atmosphere. Thank you!

Training Participant

We would like to thank you once again for enriching our summit as a speaker with your excellent talks. We collected initial participant feedback right after the event, and it was consistently positive.

Conference Organizer

I took part in your web security training over the past two days — it was awesome. I like the practical approach with the marathon app to try out different cases. Your slides and presentation style are really good and I learned a lot. You definitely know what you’re talking about and convey that knowledge well.

Training Participant

Great training — I had to file a bug for an app right away :D.

Training Participant

Very interesting training. Pedagogically well structured. Especially the step-by-step escalation of the attack, followed by a demonstration of automated off-the-shelf attack tools.

Training Participant

Thank you for the exciting time at the Web Security Bootcamp. With a high level of competence and “escape-the-room” flair, it was fascinating to look at vulnerable doors and gates from the attacker’s point of view, and to learn the many ways to keep those paths closed and secure. A training I can recommend 100% to every developer.

Training Participant

Thank you. I was a complete security beginner and now definitely have a different view of my source code. For many things I used to think mainly about clean code and good style, but it clearly also makes sense from a security perspective to separate data and code.

Training Participant

I loved that you encouraged people to ask questions. Unusual at first how often you did it, but that’s how questions actually get asked :)

Training Participant

I also loved that you had everything prepared so you could always work hands-on if you wanted. You could tell you have routine. At the same time it never got boring.

Training Participant

Great training! Not just technically strong, but also excellently delivered. There genuinely weren’t any dull moments. And with the handout you feel equipped for upcoming challenges.

Training Participant

It was great to always see how far you can take exploiting vulnerabilities!

Training Participant

The training was amazing. I’m quite new to security, and I was speechless at how many everyday systems can be broken when you know what to look for. WOW. Also amazing job, Christian — talking for so many hours with this ease and answering every question. What I appreciated very much was that every question was treated seriously. You motivated people to ask questions! Thank you very much for the great training, but also for the great atmosphere!

Training Participant

Thank you again for the seminar. You could follow along well, and each topic still went quite deep. Injection and XSS in particular reminded me how important those fundamentals are — and how valuable it is to see them explained this clearly.
