Data Loss Prevention Diaries: Tales from the Trenches

Deploying DLP in Microsoft 365? You’re probably doing it wrong. This session walks you through the real-world lessons from dozens of DLP rollouts - what to avoid, what to monitor, and what actually works when it comes to policy tuning and user behavior. From Exchange to SharePoint to Power Platform, we’ll cover the hidden traps and the winning strategies.

AI Data Exposure Paths in Microsoft 365: What Your AI Can See (and Why)

AI agents in Microsoft 365 do not create new permissions-but they dramatically amplify existing ones. When Copilot, Copilot Studio agents, or Power Platform automations are deployed, data exposure scales instantly across SharePoint, OneDrive, Teams, and connected third-party services.
This session breaks down how AI actually accesses data inside Microsoft 365, mapping real data exposure paths that most organisations don’t realise exist. We’ll explore how permissions, sharing links, connectors, and low-code automation combine to surface sensitive information to AI agents-often unintentionally.
Special attention is given to Copilot Studio and low-code blind spots, where connectors and agent actions can bypass traditional review processes.

Solutions Covered:
• Microsoft 365 Copilot
• Copilot Studio
• SharePoint Online, OneDrive for Business, Microsoft Teams
• Power Platform (Power Apps, Power Automate connectors)
• Microsoft Defender for Cloud Apps
and many more

Bring it into your purview: hard lessons from real Microsoft Purview deployments

Most organizations already own Microsoft Purview through Microsoft 365 E5, but few are getting real value out of it. Purview is powerful. It is also not simple. And when deployments go wrong, the impact reaches far beyond IT. This session draws on repeated, hands-on experience deploying Purview across organizations of varying size and complexity. It walks through six comprehensive field-tested lessons covering both the business and technical realities of making Purview work in production. Not theory, not product overviews. Honest, practical guidance from implementations that succeeded, implementations that stalled, and a few that nearly caused significant business disruption.
We'll connect the dots across the broader Purview ecosystem and the services it depends on, including Microsoft Information Protection, DLP, Insider Risk Management, Purview Audit, DSPM for AI, and how these interact with identity controls like Privileged Identity Management for Purview RBAC. We'll also examine where Microsoft Intune fits in, because Purview depends on endpoint signals and browser extensions to enforce what you configure.
Beyond the technology, this session addresses the organizational challenges that determine whether a Purview initiative succeeds or fails. Ownership, governance models, responsibilities, and the adoption obstacles that surface long before policy configuration becomes the bottleneck.
You'll leave with a clear implementation strategy, a realistic roadmap, and the kind of perspective that only comes from doing this work in production, repeatedly.

Engineering High-Accuracy Data Classification in Microsoft Purview

Out-of-the-box classifiers in Microsoft Purview are built for general use-not for the unique data patterns found in real organisations. The result is often false positives, missed sensitive data, and a lack of trust in security controls.
This technical deep dive explores how to engineer high-accuracy classification models using custom sensitive information types, Exact Data Match (EDM), and trainable classifiers. We’ll cover design principles, testing strategies, threshold tuning, and governance practices that materially improve classification reliability.
Attendees will leave with practical techniques to make classification reflect how their organisation actually stores and uses data.

Mastering Microsoft Purview sensitivity labels: the things you only learn the hard way

Sensitivity labels look simple in demos. In production, they're anything but. This session goes well beyond the basics of Microsoft Purview sensitivity labels into how they actually behave across cloud repositories, workstations, and on-prem file shares. We'll break down encryption models, the difference between user-defined and admin-defined permissions, permission templates, and how label policies are evaluated when multiple conditions compete for the same content. More importantly, this session is about what goes wrong and how to get ahead of it. Real-world failures where labels blocked collaboration, encryption broke business processes, and organizations lost access to their own data because the person who encrypted it left and no one planned for that. We'll look at which permissions to assign, which to hold back, and how small scoping mistakes cascade at scale.
We'll also dig into the role of custom sensitive information types and trainable classifiers in auto-labeling, why out-of-the-box classifiers fall short, and the gotchas that cause auto-labeling to either do nothing or encrypt far more than intended. Labeling and classification are the foundation for everything in data security, from DLP to Insider Risk to controlling what Microsoft 365 Copilot can access. If your labels aren't right, nothing downstream works properly. We'll cover how to keep Copilot from surfacing labeled content it shouldn't reach, and why getting this layer right is more urgent than ever. Expect detailed configuration walkthroughs, real production scenarios, and technical depth you won't find in the documentation.

Noise, Noise, Baby: Insider Risk Management Fine-Tuning

This 300-400 level session promises to provide attendees with a well-rounded, actionable understanding of MIP sensitivity labelling that they can implement immediately.

Hidden gems in Entra Conditional Access and design patterns that scale

Most Microsoft Entra ID Conditional Access deployments stop at enforcing MFA and requiring a compliant device. That's where the real risk begins, not where it ends.
In this session, I'll take you beyond the basics into the Conditional Access controls that actually change your security posture. We'll dig into capabilities that most teams either don't know exist or haven't configured correctly, including authentication strengths, authentication contexts, device filters, Continuous Access Evaluation, session controls, token protection, and policies for workload identities and service principals. These are areas that are often ignored but heavily targeted.
I'll also show you settings that are hiding in plain sight. Controls buried in the Conditional Access UI that give you a far higher level of granularity and stronger security than some of the more commonly used built-in options and we'll walk through how to ensure the strongest authentication methods are applied consistently, aligning every policy decision with zero trust principles across the board.
Beyond individual settings, this session tackles a problem almost every environment eventually hits: policy sprawl. Many Conditional Access deployments start strong and then collapse under their own complexity. Duplicate policies, conflicting conditions, and unclear naming turn what should be a security asset into an operational liability. I'll share scalable design patterns for structuring policies so they remain clear, maintainable, and auditable as your environment grows. You'll see real examples of sprawl and exactly how to consolidate it.
We'll also cover the tools and techniques for getting real insight into how your policies are actually behaving, not just how you think they're behaving. And we'll talk about the scenarios no one plans for, like locking out your own global admins, and how to build resilient break-glass access strategies so that never becomes a crisis.
Everything in this session comes from production. Policies that caused outages, designs that didn't scale, and lessons learned the hard way.

Laying the Right Foundation for Effective Data Protection in Microsoft Purview

Many Microsoft Purview deployments fail-not because of tooling limitations, but because organisations skip foundational steps. Teams jump straight to sensitivity labels and DLP policies without understanding what data they have, where it lives, or how sensitive it truly is.
This session focuses on building the foundational data visibility and classification layer required for effective protection across Microsoft 365, endpoints, and cloud data sources. You’ll learn why early discovery and accurate classification directly determine the success of downstream controls like DLP, Insider Risk Management, and eDiscovery.
This is a practical session for anyone planning, redesigning, or recovering a Purview implementation.

Session Level: 300 (Intermediate–Advanced)
Target Audience:
Security engineers, Purview administrators, compliance teams, M365 architects
Solutions Covered:
Microsoft Purview Information Protection, DLP, Insider Risk Management, Audit

Microsoft 365 Copilot under the hood: what it sees, what it leaks, and how to stop it

Microsoft 365 Copilot doesn't introduce new data risk. It exposes the risk you already have. Most organizations preparing for Copilot focus on licensing, adoption, and productivity gains. Very few start with the question that actually matters: what can Copilot see, and should it be able to see all of it? The answer, in almost every environment I've assessed, is no.
This session breaks down how Copilot actually works behind the scenes. How it interacts with the Microsoft Graph, how it retrieves content from SharePoint Online, OneDrive, Exchange Online, and Microsoft Teams, and why permissions, not AI, ultimately determine what it can access. Once you understand the retrieval model, the oversharing problem becomes obvious. And it's a problem that exists in your environment right now, whether you've deployed Copilot or not.
We'll walk through real scenarios where Copilot surfaces sensitive or inappropriate data. Not because the technology is broken, but because access controls were too broad, sharing defaults were never tightened, and no one audited what was actually reachable. We'll also demonstrate how prompt injection attacks can manipulate Copilot outputs and why this is a real concern in enterprise environments, not just a research curiosity. From there, we shift to what you can do about it. Using Microsoft Purview, Defender, Intune, Entra and more, we'll show how to reduce your exposure surface and prepare your environment properly before rolling Copilot out to production users. If you've already deployed it, the same controls apply, they're just more urgent. If you're planning a Copilot rollout or already in one, this session will likely change your approach.

Not secure by default: 20+ Microsoft 365 settings you must fix immediately

Microsoft 365 is not secure out of the box, and attackers know it. Most tenants ship with default configurations that leave critical gaps across identity, email, endpoints, and data protection. These gaps are not hypothetical. They are actively exploited in the wild, and many organizations don't realize they're exposed until something goes wrong.
This session draws on real-world security assessments, incident response engagements, and environments that were either breached or dangerously close to it. I'll walk through more than 20 high-impact security settings across Microsoft Entra ID, Exchange Online, Microsoft Defender for Office 365, Microsoft Intune, Power Platform, and Microsoft Purview that are consistently misconfigured, overlooked, or left at insecure defaults. This session is fast-paced and grounded in what I've seen across production environments, not compliance checklists or vendor documentation. Every misconfiguration is shown with the context of why it exists, what it exposes, and what an attacker does with it. If you're responsible for the security posture of a Microsoft 365 tenant, this is the session that shows you what's likely already wrong in yours.

Securing AI Apps and Agents with Microsoft Purview

As organisations adopt AI-powered applications and autonomous agents, sensitive data is being accessed, generated, and shared in entirely new ways. Traditional data protection models-designed for static users and predictable data flows-are no longer sufficient.
This session explores how Microsoft Purview can be used to secure AI applications and agents end to end. We’ll examine how data flows into and out of AI systems, where new exposure points emerge, and how to apply controls using DSPM for AI, DLP, Communication Compliance, and Insider Risk Management-without stalling innovation.
Rather than focusing on theory, this talk highlights real control patterns, visibility gaps, and governance decisions organisations must make when deploying AI at scale.
Key Takeaways:
• How AI changes data risk models
• Where Purview provides visibility-and where assumptions break
• Practical guardrails for AI-enabled environments

Session Level: 400 (Advanced / Strategic-Technical)
Target Audience:
Security architects, data security leads, compliance leads, AI governance teams, SOC leaders
Solutions Covered:
Microsoft Purview DSPM, DSPM for AI, Data Loss Prevention (DLP), Communication Compliance, Insider Risk Management, Microsoft Copilot integrations

The tenant is the new server: Are you protecting it well enough?

Think your Microsoft 365 tenant is secure? Think again. Most compromises happen because the basics weren’t nailed – identity, devices, data, and governance. This session is your 90-minute crash course on how to lock down the areas attackers love to exploit.

We’ll break down the Microsoft security stack that matters: Entra ID, Intune, Defender XDR, and Purview. No marketing fluff, no endless theory – just the hard-hitting controls and configurations that make the biggest impact.

Walk away knowing exactly where to focus your time and budget to prevent business compromise.
