**IMPORTANT PLEASE RSVP:** https://www.jug.ch/html/events/2026/data-streaming-security.html \*\*\* ROOM: PH Zürich, Lagerstrasse 2, 8090 Zürich, Building LAB, Room H015 AGENDA: 18:15-19:30h: Talk incl. Q/A * After the talk, you will have the opportunity to exchange ideas and network with the speaker and professional colleagues over beer and rich finger foods. **SPEAKER**: Olena Kutsenko **COMPANY**: [Confluent](https://www.confluent.io/) 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.

A 1:1 Reiki journey where you receive focused healing, intuitive guidance, and space to reconnect with your inner flow.

**\*\*\*\* More details and sign up at: https://aifalliance.org/summit-2026/ \*\*\*\*** **What is AI Freedom Alliance?** AI Freedom Alliance promotes the responsible growth of AI guided by practical, commonsense ethics. Our nonprofit is built by professionals from a wide range of industries and is made up entirely of small- and mediumbusiness representatives—never large tech companies.

The summit will feature interactive and educational sessions led by thought leaders, technologists, policymakers, and advocates who are passionate about making AI fair, transparent, and beneficial for everyone. **Why Attend?** Learn about the legal and technical challenges with implementing AI solutions within your organization. Build better solutions while protecting your organization from legal and compliance risks. And learn how to think strategically about AI as a differentiation tool for your business.

**People Analytics 101: Making Sense of Compensation Data** Compensation data is one of the most widely used and widely misunderstood forms of people analytics. The session will cover where compensation data comes from, including market pricing data, internal payroll data, and benchmarking sources, and how companies think about structuring and analyzing that information. We will explore how compensation data is leveraged to set salary ranges, manage internal equity, support hiring and retention, and align pay with business strategy. A portion of the session will address common data challenges and limitations, such as market noise, inconsistent job matching, and incomplete datasets, while keeping the primary focus on practical use rather than technical depth. The session will also look ahead at where the space is going, including the growing impact of pay transparency laws, expanding pay equity requirements, and emerging regulations in the US and Europe that require organizations to report on gender and pay gaps. The goal is to give attendees a clear mental model for how compensation analytics works today and why getting it right is becoming increasingly critical. (note: we are back at Rev1 this month!) **About Our Speaker** [Alex Moore](https://www.linkedin.com/in/alexscottmoore/) is the founder of [Moore Cooperative](https://moorecooperative.com/), where he advises organizations on compensation strategy, pay equity, and people analytics. His work focuses on helping organizations like the Ohio Supreme Court design, analyze, and communicate compensation systems that are data-informed, defensible, and aligned with organizational goals. Alex lives in Granville, Ohio and has three little kiddos. More info at [cbusdaw.com](https://cbusdaw.com)
