We are kicking off the year by celebrating 2 years of Berlin Cybersecurity Social and starting strong with two highly practical sessions focused on impact, growth, and doing more with less. As budgets tighten and expectations rise, security leaders are being asked to optimise spend while also advancing their own careers. This anniversary edition of BCS is all about exactly that. How to make smarter security decisions, stretch limited resources, and make sure your work gets the recognition it deserves. Think new year, new priorities, and new momentum. *** **Talk 1: Why Risk Appetite Statements Matter: Getting the Board Onboard** James Tucker, Group Head of Information Security at Awin Global This session explores how risk appetite statements can be used to connect technical security controls to board-level decision-making. James will share how framing security through risk appetite enables clearer conversations about prioritisation, investment, and trade-offs, particularly when budgets are tight. **Key Takeaways** * How to use risk appetite statements to frame security decisions * How to translate technical controls into business and board-level language * How to support risk-based investment and prioritisation discussions * **Talk 2: Making Invisible Security Work Visible** **Alisa Reznik, COO, tech consultant, and mentor for tech leaders** Security professionals protect the company constantly, yet their impact is often invisible by design. In this session, Alisa will show how to make security work visible without bragging, translate technical outcomes into business value, and build career momentum alongside fast-moving threats. **What you will learn** * How to make your work visible without bragging * A simple system to gain recognition and career momentum * How to communicate security impact in business terms *** We will be celebrating the 2-year anniversary of Berlin Cybersecurity Social with networking before and after the talks, familiar faces, new connections, and the same community energy that has shaped BCS from the start. A practical start to the year. Smarter budgets. Clearer impact. Stronger careers. **About Berlin Cybersecurity Social:** This meetup is open to cybersecurity professionals of all levels, from beginners to experts.

However, surfacing these “hidden gems” at scale is a major challenge for any dynamic marketplace. At GetYourGuide, we tackled this by combining large language models, semantic vector embeddings, and a robust human-in-the-loop process to automatically identify and categorize novel customer interests. Join me as I dive into how we created this AI-driven solution and how we achieved scalable, granular and relevant categorization of our activities. **Description:** How do you help a traveler find something they never knew they wanted? In this talk, I will explore the exciting journey of developing an AI-driven solution to identify novel customer interests at GetYourGuide. With thousands of new activities onboarded weekly, manual categorization became impractical, prompting the need for automation. This talk will walk you through our end-to-end solution: * The problem: the challenges travelers face in discovering relevant and unique experiences, the organizational complexity of this on our platform and its business impact * The AI journey: From raw LLM-based extraction to vector embeddings, clustering, all the way to a robust human-in-the-loop pipeline. I’ll share how we iterated from noisy prototypes to an impactful system, launching 300+ new interests and driving significant engagement and net revenue uplifts * What we learned: The realities of working with LLMs in production-like settings, more specifically hallucinations and issues with relevance, granularity and semantic deduplication. We found out that the line between useful innovation and unwanted noise can be surprisingly fine when using LLM’s. I’ll share practical examples of these challenges and how we’re iterating to address them. * Impact and future directions: How we achieved a 10x increase in manual acceptance of AI-suggested interests in just two iterations, and what’s next for AI-driven discovery at GetYourGuide **Bio**: **Morena Bastiaansen** holds a master’s degree in Econometrics from the University of Amsterdam and currently works as a Data Scientist at GetYourGuide in Berlin. She combines her passions for machine learning, language, and travel to build impactful systems for travelers worldwide, with a current focus on personalization in email marketing. Morena is also actively involved in the local tech and ML community. **Talk 2: Deep dive into data streaming security** **Abstract**: Data streaming is powering everything from fraud detection and real-time analytics to patient monitoring and order fulfillment. But as the role of streaming grows, so does the risk - because many streaming platforms, like Apache Kafka, aren't secure by default. In this talk, we’ll take a practical look at data streaming security through the lens of Kafka, one of the most widely adopted streaming platforms in the world. We'll walk through what can go wrong - real examples of exposing 14M patient-doctor messages, or years of real-time delivery info to the internet - and what it takes to do it right. We'll cover the key pillars of securing a streaming system: encryption in transit and at rest, access control, monitoring, and key management. Along the way, we’ll look at the trade-offs like disk encryption vs. end-to-end encryption, what is behind field-level and envelope encryption, and the realities of using customer-managed keys in regulated industries. We'll also explore how streaming security has evolved, how real vulnerabilities (like CVE-2019-12399) highlight the need for patching and monitoring, and what successful multi-layered security looks like in production - from financial institutions to healthcare platforms. If you're building, running, or scaling streaming systems, this talk will help you see the security blind spots and give you concrete steps to protect the data flowing through your pipelines. **Bio**: Olena Kutsenko is a Staff Developer Advocate at Confluent and a recognized expert in data streaming and analytics.

(English below) \>\> der Event findet statt\, wenn sich bis 18:00 mindestens 4 Personen angemeldet haben\, sonst nicht << Worum es geht: "Kann ein Walfisch ein Wellensittich sein?" \~> Natürlich nicht, denn Säugetiere sind niemals Vögel. "Kann ein Fenster ein Getränk sein?" \~> Jeder weis, das ist unmöglich, denn Festkörper sind keine Flüssigkeiten. ABER: "Kann eine Demokratie eine Republik sein?" "Kann eine Vermutung eine Meinung sein?" "Ist etwas zu begreifen das Selbe wie etwas zu verstehen?" \~> Tja, jetzt wird's schwierig! Und es wird spannend... Nichts regt dermaßen zum nachdenken an wie dieses neue Gesellschaftsspiel. Die Spielregeln: 1. Jeder schreibt einen Begriff auf einen Zettel. 2. Die Zettel werden paarweise gezogen. 3. Per Beamer werfen wir die Bedeutung der zwei Wörter an die Wand. 4. jeder kann per Laptop (zur Not auch per Smartphone) die Bedeutung ergänzen / editieren, muss dafür ggf. Beispiele angeben warum etwas gleich sein können soll, oder nie gleich sein kann. 5. nach einer Zeit fällt niemandem mehr etwas ein. Unterschiede und Gemeinsamkeiten zwischen den beiden Begrifflichkeiten sind deutlich herausgearbeitet. Dann wird der Punktestand gezählt: (+1) Jeder verbliebene neue Beitrag in der Bedeutung ergibt einen Pluspunkt (-2) aber jeder wieder gelöschte neue Beitrag gibt zwei Minuspunkte. (+5) jede Verbesserung der bisherigen Bedeutung in Reclue ergibt plus 5 Pluspunkte Die Auffassungen aller Mitspieler werden viel klarer, erst recht wenn man häufig mitspielt. Ziel des Spiels ist nicht, dass irgendwer am meisten Punkte sammelt, sondern, dass alle zusammen überhaupt auf mehr als 50 Punkte kommen. Das Spiel funktioniert auch mehrsprachig. Man kann auch von Zuhause aus online mitmachen. Den Zugang können wir dann über die Kommentare hier organisieren. Bring deinen Laptop mit, dann wird es einfacher... Warum macht das Spiel klug? Schach trainiert das Konzentrationsvermögen. Aber es hat mit der Wirklichkeit nichts zu tun. Dieses Spiel hingegen schon, denn genau mitdenken zu können setzt voraus genau zu unterscheiden. Andernfalls assoziiert man das eine sprunghaft mit irgendetwas anderem. Aber ob die Assoziationskette notwendiger Weise der Fall ist, ist nicht klar - und andere Aspekte sind vll. viel wichtiger. Und dann irrt man in wirren Assoziationen, entscheidet wenig optimal, verliert Zeit, usw. Mit der Übung über dieses Spiel nicht mehr! Wer die Bedeutung der Wörter sauber ausdifferenziert wird immer klüger. \*\*\* english version \*\*\* "Can a whale be a parakeet?" \~> Of course not! "Can a window be a drink?" \~> Everyone knows that's impossible. "Can a democracy be a republic?" "Can a conjecture be an opinion?" "Is grasping something the same as understanding something?" \~> Well, now it gets tricky! And it gets exciting... Nothing stimulates thought quite like this new party game. The rules: 1. Everyone writes a term on a slip of paper. 2. The slips of paper are drawn in pairs. 3. We project the meaning of the two words onto the wall using a projector. 4. Everyone can add to/edit the meaning using a laptop or smartphone, and must provide examples of why something could be the same, or could never be the same. 5. After a while, no one can think of anything else. The differences and similarities between the two words are clearly highlighted. Then the score is tallied: (+1) Each new entry adding meaning earns one point. (-2) However, each deleted entry deducts two points. (+5) Each improvement on the existing meaning in Reclue earns five points. The understanding of all players becomes much clearer, especially with frequent play. The goal for the entire group is to reach at minimum 50 points. The game also works in multiple languages. You may join us from home using the internet. Comments in meetup-app will be used to organize that it works. The location (somewhere in Prenzlauer Berg) will be published the day when it takes place.
