This week was super busy, but it started out really nice with attending #BSidesMunich together with a bunch of my colleagues. Fully enjoyed my time there, seeing folks from last editions and also #osco25 again, learning together. Many thanks to the organizers for giving us this space! Finally, here are the #sketchnotes I took during the #BSidesMunich2025 conference day. Thread. 🧵

It was such a wonderful conference. Thank you and your fellow organisers so much for creating this space!
Reading this blog article just let me re-live part of it. Can't wait for next year :)

Just a quick thought about open spaces:
OpenSpace conferences like #socrates and #osco feel like enabling conferences. They bring you into contact with like minded people, let you try yourself in various situations like presenting, taking part, asking questions. They also bring you into contact with seasoned speakers and facilitators. And all persons are willing to learn and teach.

Back from an amazing long weekend at #osco25. We had two great keynotes . One by @m1r314 about AppSec and one by @bkastl about history repeating itself (in security).
There were great sessions over both days and nights of open space and I'm full of new ideas, hopes and a bit lack of sleep. And also a lot of new contacts.
Thank you again @OSCo ! It was an absolute pleasure to be there.

Last lunch conversation was had, last train ride was shared. Now #osco25 is slowly starting to fade out and form fond memories. What a wonderful time we had together the last four days. Huge thanks to everyone for coming and contributing and sharing so much invaluable feedback - this gives more energy than you might realize. Lots of love also for my fellow organizers to make this unique event called #osco happen! My heart is full. ❤️

Wow. Even the last morning of #osco25 was enlightening. 💡 Started with insightful breakfast conversations on company cultures and reward systems driving behavior. Continued with me giving a super relaxed version of my workshop "Secure Development Lifecycle Applied - How to Make Things a Bit More Secure than Yesterday Every Day". Seems folks had fun practicing together and I gained a feeling for this workshop again. 🎉 #osco gave just the right space and crowd for it.

On my way back home after an amazing (prolonged) weekend at @OSCo.
It was wonderful connecting with new faces, deepening existing relationships, and gaining valuable insights through exchange and discussion.
A huge thank you to the organizing team, the hotel staff, and all fellow participants for making this happen!

It's the last day, the last morning of the Open Security Conference 2025. We've learned so much together these days. Now's the time to go deeper into some of those topics, spend the rest of the time for networking, relax and breathe this community spirit.
We're very much looking forward to seeing lots of these folks again in 2026. 😊

Well, it's not over yet! 💜

Aaaaand it's another full day of open space at the Open Security Conference 2025! Participants just started to present their session ideas for today. Oh the tension, we're super curious what we'll all learn today! 😁 Yet one thing is for sure - whatever it is, it'll be in the common interest for folks. One of the beauties of an open space. 🌻

What a day. Already learned so much from this crowd - "be ready to be surprised" really holds true every time at #OpenSpace conferences like ours! 🌟
Off for dinner, afterwards the evening fun will start. 😁

What an awesome crowd! The first evening at the Open Space Conference 2025 was a blast. ☺️
While the official program ended, it's perfect time now to hang out and get to know a few folks before the first open space day starts tomorrow. Or just relax and rest. Or take a night walk. Or whatever is right for you right now 😉

Give visibility to champions and encourage volunteers. Bring security closer to teams and foster a culture of shared knowledge.

Clear expectations and structured onboarding for security champions really helped, including sharing security baseline knowledge.

Security champions know the context of their team, invaluable. Monthly meetings, 1 to 1 sessions, security seminars. Share knowledge and build relationships.

Security champions embedded in each domain to bridge gaps. This transformation didn't happen overnight, and it's a never-ending journey.

Security is no longer enforced through gates, teams own their security. Metrics and dashboards enable teams to track progress towards their goals.

Built our own security champions framework. Defined goals, had structured engagement. Onboarding was smooth. Cultural expansion. We made security look cool!

Centralized information from all tools into one. Gained visibility on company posture. But still no idea what's happening in teams.

Yay, metrics work! Yet needed to become strategic and intentional. Let's define our goals, ask questions how to achieve these goals, find metrics to support.

This kept happening, had to switch the approach. How about security metrics? Pivot from enforcers to enablers! Put the power into the hands of teams.

If you are wondering what topics could happen at @OSCo , here one possibility.
I will bring a bunch of #cybersecurity themed games.
Including Elevation of Privilege (#EoP), various adaptations like #Cornucopia, Cyber Threat Defender (#CTD), #BackdoorsAndBreaches, and many more.
If you are interested in trying them out, registration for #osco25 is still open.
If you know other games, bring them (or let me know 😁)

Today is Women's Equality Day, a day celebrated in the US and a day important everywhere. Or shall we say it's a reminder of the inequality and inequity that's still prevalent across the world for folks who are not white cis men? Yes, we shall. We all need to do better. Today we learn again.
When white women were granted the right to vote in the US: https://en.m.wikipedia.org/wiki/Women%27s_Equality_Day
When white women were granted the right to vote in various countries: https://en.m.wikipedia.org/wiki/Timeline_of_women%27s_suffrage
When nearly everyone was granted the right to vote across the world: https://en.m.wikipedia.org/wiki/Universal_suffrage
Let's continue leveling the playing-field, for everyone.

Happy International Self-Care Day! Yes, you read right. And yes, that's today.
Why exactly today? Well, last year we spoiled the solution, this year it's quest time! Go ahead and find out why it's exactly on July 24th. You might even guess it. 😉
But riddles aside, it's quite an important day to observe. Think about it: did you do something for yourself today, just for the sake of your own needs and joy? What about yesterday, any plans for tomorrow?
How about getting up right now at the time you're reading this and doing a small thing that gives you joy (or a big one, we don't judge). However that looks like for you! Whatever is right for you is right for you.
Let's cheer for others doing what is right for them. 💜
