Preventing Data Exposure: Where to Start?

Preventing Data Exposure

Seattle WA, USA– September 15, 2025.

Where to Start?

As an information protection or compliance administrator, it’s your worst nightmare: you get a call that your customers’ PII data has been found in the wild. Your mind races to try to understand how this could have happened. For a few months you’ve been trying to convince the higher ups to remove anonymous access to files in SharePoint Online and OneDrive for Business. You recently implemented sensitivity labels to classify and encrypt PII data, but you know it has yet to be universally adopted. Hell, you’ve been trying to get a data retention project off the ground to reduce your attack surface. But that’s not what has been keeping you up at night – that’s your organization’s recent implementation of a new Gen-AI tool.

It’s been received warmly; users are enthusiastic about Gen-AI’s ability to help them craft content and quickly research questions across your intranet. However, you and your team members know that with a simple prompt, users can quickly access sensitive information they are not authorized to view. You’ve already heard the complaints: a direct report asked the tool how much their boss makes, a coworker asked why one of their colleagues was let go. Could this be the source of the data leak? Could someone have asked the tool for a list of customer PII information and then exfiltrated the results?

Through Microsoft 365, you have the tools necessary to prevent data overexposure. But you know there are gaps in the current deployment. How could there not be? It’s a large enterprise organization, serving customers worldwide and no one was thinking about Gen-AI during initial implementation. You need to get your arms around this to prevent additional data overexposures – and fast. But where do you start?

Introducing E-Visor for Document Tracking & Protection

Synergy Advisors has built a powerful analytics and visualization solution designed to detect data exposure in Microsoft 365. E-Visor is installed directly in your tenant so your private data never leaves the organization. It works immediately; within hours of installation, you can start to see actionable insights about the data at risk in your environment and you can clearly understand what to do to mitigate it.

E-Visor for Document Tracking & Protection presents both a summary and a detailed view of your potential data overexposure.

The summary view displays the configuration status of key parameters that affect end user ability to share files outside the organization and access to files via Gen-AI tools. It also shows you a summary of the files analyzed in SharePoint Online and OneDrive so you can see how many files exist in your data estate, how many of those files contain sensitive information types (as leveraged by Microsoft Purview), and where those sensitive files are stored.

The detailed view drills down on this information. Now you can see your files broken down by sensitive information type, sharing type, Gen-AI accessibility, and more.

E-Visor provides an intuitive risk scale that shows you which files are most at risk to data overexposure by examining the sensitive information types they contain, their share status, and their protection status. For example, a file that contains multiple sensitive information types, that is not encrypted using Microsoft Information Protection, and that is shared anonymously would receive the highest risk level. By contrast, a file without sensitive information, or one protected by the appropriate controls, would not represent a significant risk to overexposure.

Armed with this analysis, you can identify security gaps, prioritize corrective actions, and facilitate more effective decision making aligned with your data protection objectives. Leverage our team of compliance architects to help you optimize your Microsoft 365 controls and ensure your data is secure from every overexposure risk. Here is your starting point. This is your playbook, designed to help you understand the risk your organization faces from data overexposure and exactly what you can do to mitigate it.
