If you are living in The Netherlands, by now, you may well have noticed the amount of open water. If you enjoy cycling in the city, you may wish to feel safer as you navigate the bridges and canals. And you may also want to get ready for visiting the beach, pools or the many lakes this summer. Learning how to swim takes approx 1 year and it all starts with the very first lesson. New comers enroll via our website and pay € 30,50, this is the first lesson and a goody bag. After the class you agree with the personal swim coach how to continue to obtain your final objectives. Enrolling is only possible via [www.your-personal-swim-coach.nl ](https://www.your-personal-swim-coach.nl/)hence a rvsp via meetup is not enough.

**From DLP Best Practices to Government Cloud Security with Microsoft Purview** **Datum, tijd, locatie** 📅 Datum: Vrijdag 29 Mei 2026 🕐 Tijd: 12:30 - 17:00 📍 Locatie: RawWorks, De Vork 2, 3984 PA Odijk **Introductie** Tijdens deze editie van de Dutch Data Security & Compliance Community Meetup #8 staat de realiteit van data security in zowel commerciële als publieke omgevingen centraal. We combineren twee krachtige praktijkperspectieven: de implementatie van Data Loss Prevention (DLP) binnen organisaties en een grootschalige cloudmigratie binnen de publieke sector met Microsoft Purview. Deze middag draait om concrete ervaringen, technische en organisatorische uitdagingen en lessons learned uit de praktijk. Verwacht inzichten die direct toepasbaar zijn om jouw data security en compliance aanpak te versterken. **Wat kan je verwachten?** **Sessie 1 – DLP in de praktijk: Best practices en lessons learned from the field** Martijn van Geffen (Microsoft) DLP binnen Microsoft Purview wordt steeds complexer door de opkomst van AI en het gebruik van meerdere enforcement engines. Traditionele aanpakken schieten tekort wanneer data via AI-tools wordt gedeeld, gekopieerd of geüpload. In deze sessie deelt Martijn van Geffen (Microsoft) praktijkervaringen met DLP-implementaties, met speciale aandacht voor DLP for AI. We bespreken hoe verschillende enforcement engines (Endpoint, Edge, Network, Cloud Apps) zich gedragen bij AI-scenario’s zoals copy/paste en file uploads — en waarom dit vaak leidt tot onverwachte pop-ups en policy-interacties. Daarnaast gaan we in op het verbeteren van de gebruikerservaring (policy tips, Outlook customizations, oversharing notificaties) en het reduceren van false positives. Je krijgt concrete best practices voor het ontwerpen van effectieve policies, het kiezen van de juiste engine voor AI-use cases en het beheersbaar maken van DLP in een moderne Microsoft 365-omgeving. **Customer case – Data Security x Heerenveen** Femke Helgering (RawWorks) Ronald Hofstra (Gemeente Heerenveen) Hoe beveilig je gemeentelijke data tijdens een cloudmigratie naar Microsoft 365? In deze customer case staat het data security traject van Gemeente Heerenveen centraal. Na de migratie is gestart met de implementatie van Microsoft Purview-functionaliteiten zoals Sensitivity Labels, Data Loss Prevention (DLP) en Data Lifecycle Management. Dit bracht zowel technische als organisatorische uitdagingen met zich mee op het gebied van governance, adoptie en bestaande werkwijzen. Femke Helgering (RawWorks) en Ronald Hofstra (Gemeente Heerenveen) delen de praktijkervaringen, keuzes en lessons learned uit dit traject. Je krijgt inzicht in hoe security en gebruiksvriendelijkheid in balans kunnen worden gebracht binnen een overheidscontext. **Agenda** * 12:30 – Inloop met koffie en lunch * 13:30 – Opening door DDSCC * 13:45 – Introductie door RawWorks * 14:00 – DLP in de praktijk: Best practices en lessons learned from the field, Martijn van Geffen, Microsoft * 14:45 – Pauze * 15:15 – Customer case - Data Security x Heerenveen, Femke Helgering & Ronald Hofstra, RawWorks & Gemeente Heerenveen * 16:00 – Ronde tafel gesprekken * 16:30 – Borrel & netwerken (tot 17:00 uur) **Additionele informatie** **Parkeren** Bezoekers kunnen parkeren bij de parkeerplaats van de Sint Nicolaas Kerk: Sint Nicolaaslaan 1, 3984 JA Odijk Vanaf daar is het enkele minuten lopen naar de locatie van RawWorks.

👀 **LOOK at my lab!** *Een kijkje in de homelabs van I-share.* Ben jij ook nieuwsgierig naar waar I-share collega's zich mee bezighouden in hun vrije tijd? Spoiler: dat zijn vaak servers, zelfgebouwde netwerken en softwareprojecten die nét iets verder gaan dan 'gewoon voor werk'. Tijdens onze Meetup op donderdag 28 mei nemen: * Paul Aldabagh; * Daan Beltman; * Laurens Ghijsen; * Michael Loeffen. je mee in hun homelab! Ze laten zien wat er thuis draait, waarom ze ermee zijn begonnen en hoe hun setup zich heeft ontwikkeld. **Wat kun je verwachten?** Elke korte presentatie neemt je mee langs: * Wat is het? - Wat draait er eigenlijk? * Hoe begon het? - Het ontstaan en het idee erachter. * Let's talk tech - De technische opzet. * Is het ooit af? - Of blijf je altijd tweaken? 😉 **Voor wie?** Voor iedereen die nieuwsgierig is naar wat er allemaal thuis kan draaien. Je hoeft zelf geen homelab te hebben, interesse is genoeg. En wie weet ga je naar huis met frisse ideeën of zin om zelf te gaan bouwen! *Het programma zal deze avond als volgt zijn:* * Vanaf 17.15 u: inloop * Rond 17.30/18.00 u: eten * 18.30 u: start sessie * 20.00 u: afsluiting We zien jullie graag dan!

𝗗𝗮𝘁𝗮 𝗧𝗵𝘂𝗿𝘀𝗱𝗮𝘆 𝗶𝘀 𝗯𝗮𝗰𝗸 — 𝗮𝗻𝗱 𝘁𝗵𝗶𝘀 𝗼𝗻𝗲 𝗶𝘀 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁 🌱 On **Thursday, May 28**, we are proud to host a special **Data Thursday** edition at **B. Amsterdam**: **Cloud & Climate Pub Quiz** ☁️🌍 This will not be a classic sit-back-and-listen meetup. This is a **taste-of-tech game night** where #climate, #cloud, #AI, #CO₂, #costoptimisation and a bit of controlled chaos come together in one big interactive quiz. At **Data Tribes & EcoVerum,** we believe that climate impact, sustainability reporting and regenerative transformation all start with better data. This evening brings that belief to life in the most Data Thursday way possible: with sharp questions, practical insights, team play, pizza and drinks. Your personal quiz masters for the evening: 👷‍♂️ **Henk van der Valk** Platform & Intelligence Architect 👷‍♂️ **Marcel van der Kuil** Data & AI Impact Engineer Together, Henk and Marcel will join forces as **Buurman & Buurman for Cloud & Climate**, fixing things one quiz round at a time. Think climate science, cloud optimisation, AI-assisted answers, sharp questions, practical insights and probably a few moments of **“A je to!”** along the way. The evening includes three rounds: 🌍 **National Climate Quiz** 🌡️ **Climate Interactive EN-ROADS simulator** ☁️ **Cloud optimisation: cost, CO₂ and Scope 3** Bring your laptop. Teams will compete for points, prizes and eternal Data Thursday glory. AI is allowed, but beware: some answers need to be explained in your own words. 𝗣𝗿𝗼𝗴𝗿𝗮𝗺 **// 18:00** — Doors open + pizza **// 18:30 – 19:15** — First round **// 19:15 – 20:00** — Second round **// 20:00 – 20:45** — Third round **// 20:45 – 21:00** — Wrap-up / evaluation **// 21:00 – 21:30** — Drinks & networking **// 21:30** — End 📍 **The Henry, B. Amsterdam — B.1** Johan Huizingalaan 763a, Amsterdam A big thank you to **B. Amsterdam** for once again supporting the Data Thursday community. Because without reliable data, there is no reliable climate action. And this time, we are testing what grows when cloud, climate, AI and community come together. Greetings, Data Tribes Inc & EcoVerum

Every AI pipeline starts with one question: where does the data come from? In this hands-on workshop, we'll answer that question using Scrapy, one of Python's most powerful web scraping frameworks. You'll go from a blank project to a working spider that harvests structured data from the web, ready to feed into your next AI or data science project. We'll cover: • Scrapy vs. lighter tools (Requests & Beautiful Soup), and when each makes sense • Extracting data from HTML using CSS selectors • Following links and handling pagination at scale • Writing clean, structured output to a file • The ethical and legal side of web scraping Bonus (Gold Star): a chapter on scraping JavaScript-rendered pages for those who want to go further. 🐍 Python basics assumed — no prior scraping experience needed **Agenda** \- 18:00 Doors Open \- 18:30 Start of the Workshop \- 20:15 Workshop Closing & Announcements \- 20:30 Networking \- 21:00 Event Closing **GitHub Repo** [Scalable Data Harvesting for AI](https://github.com/pyladiesams/scalable-data-harvesting-for-ai-may2026) **Stream** [YouTube Stream](https://www.youtube.com/watch?v=0wqXbShaAvU) ​**📧 Contact** Are you interested in speaking at one of our events?

You’ll discover how to translate business objectives into the right customer questions and how to act on those insights immediately to accelerate growth and sales. By bringing the live voice of thousands of (potential) customers into the decision-making process, organizations can ask the right questions at the right time and turn insights into measurable business impact: from increased sales and customer loyalty/experience to stronger brand awareness and more effective activation strategies. **Talk 2: Synthetic Personas – real insights or digital illusions?** [Kate Foszcz](https://www.linkedin.com/in/katarzyna-foszcz/?locale=en), AI Product designer @ Ebay Can synthetic personas help us make better business decisions, or are we just interviewing very convincing imaginary friends? In this talk, Kate will explore where synthetic personas can actually bring value, from testing assumptions to speeding up research, and where they can quietly mislead us with biased, overconfident, or poorly grounded answers. Expect a practical look at how to design these systems responsibly, when to trust them, and when to go back to real humans. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- \#\#\# SCHEDULE 18:00 - Doors open.

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD
