Session 1: From headlines to in control: Prevent data leaks in the age of AI
Speakers : Edine Olijve & Justine Wolters

Outline:
Recent news stories highlight how easily things go wrong for organisations: hundreds of files with sensitive data accidentally ending up in public AI tools.

The question isn’t if employees will use AI, but how to enable it safely. In this session, we will dive into the technical and human guardrails needed to keep critical data secure.
We’ll explore how Microsoft Purview and Defender for Cloud Apps block sensitive uploads to untrusted LLMs. Because technology alone isn’t enough, we’ll also look at how to engage your workforce.

We will explain why certain data belongs in Microsoft 365 Copilot or approved agents and tooling, but never in public AI apps.

Session 2: The Hole in the Wall: Top 10 Misconfigurations Attackers Thank You For
Speakers : Tristan van Onselen

Outline:
Every attack we see does not start with a zero day, but with something that has been known for a long time. An MFA policy that does not apply everywhere. A legacy authentication protocol that was never disabled. An admin role that was assigned too broadly and never reviewed again. As CTO of SuperVision, I see every day, across a wide range of MSPs and their end customers, which configurations are missing by default, and those are exactly the places attackers get in first.

In this session, I will take you through the ten most common and most underestimated misconfigurations in the modern workplace. No theory, but patterns we see time and again at MSPs and among workplace engineers who are busy, have to set priorities, and sometimes assume that “default” also means “secure.”

You will leave with a concrete checklist: what you can check today, why it matters, and how to keep it structurally under control without turning it into a full time job. Practical, directly applicable, and intended to keep you one step ahead of the next attack.

Session 3: The Dawn Of The Mesh; Zero-Trust at scale
Speakers : Rex de Koning & Dennis Schoone

Outline:
For years, the hub‑and‑spoke model has been the familiar backbone of cloud network design—predictable, centralized, and increasingly… limiting. As organizations accelerate their cloud adoption and embrace Zero‑Trust principles, the old patterns start to show their cracks. Bottlenecks grow. Complexity creeps in. Security boundaries blur.

This session explores why the future belongs to mesh-based architectures: decentralized, identity‑driven, policy‑enforced, and built for the speed and scale of modern cloud environments. We’ll dive into how Microsoft’s cloud platform enables this shift, what it means for your security posture, and how to evolve your architecture without disrupting your business.

It’s time to rethink connectivity. It’s time to embrace the mesh.
