Uncover security weaknesses and data exposure in Microsoft 365 with a defensible, best practice roadmap for protection.
Data moves faster and further than ever across chat, cloud and AI tools, and many businesses lack visibility of where it is at risk.
The Purview Health Check helps you regain control. It uncovers how and where data is exposed through oversharing, insider activity or weak configuration, then turns those findings into a clear plan for protection.
With CloudGuard you get practical insight, not complexity, enabling stronger data security, smarter decisions and confidence that compliance will follow naturally.
The Purview Health Check is a non-intrusive Microsoft 365 assessment that reveals where sensitive data is at risk and how to fix it. It helps technical and security teams focus on what matters most, transforming complex environments into clear, targeted actions.
Real results from every engagement:
That’s security done different.
The assessment reviews Microsoft 365 environments including Exchange Online, SharePoint Online, Teams and OneDrive. It evaluates key Microsoft Purview components such as Data Loss Prevention, Information Protection, Insider Risk and Compliance Manager. All analysis runs in audit-only mode with no disruption to your environment.
Our structured three-phase process delivers clarity and measurable outcomes:
You’ll receive:
Every day we speak with CISOs, IT managers and security leads who face the same challenge. Data moves faster than we can control it, alerts are constant and it’s hard to know which risks really matter.
Our information sits across SharePoint, Teams and OneDrive with limited visibility. We don’t always know where sensitive data is stored or who can access it, so we’re left guessing about our biggest risks.
We’ve deployed policies and permissions but they drift out of sync as systems change. Even small configuration errors in Microsoft 365 or Purview can leave critical data exposed and open the door to insider threats.
Our team spends more time responding to alerts than reducing them. Without a clear picture of what matters most, we struggle to prioritise and the same issues keep reappearing across collaboration tools.
The Purview Health Check gives you the visibility and clarity needed to manage data risk across Microsoft 365. It highlights weak configurations, unsafe collaboration and insider activity, turning findings into a practical roadmap for stronger protection and control.
We show how and where your data is shared across Exchange, SharePoint, Teams and OneDrive.
Using Microsoft Purview analytics in audit mode, we reveal unprotected content, unsafe collaboration and insider activity without disrupting your environment. This gives you full oversight of your data landscape and the risks within it.
We assess the strength of your Microsoft 365 and Purview configurations, including Data Loss Prevention, Information Protection, Insider Risk and Compliance Manager.
Our analysis highlights coverage gaps and underused features so you can target improvements where they deliver the greatest reduction in risk.
We translate complex telemetry into clear, focused improvements.
Your tailored roadmap defines what to tackle first, how to optimise existing licences and how to maintain protection as your environment evolves. It gives teams confidence and direction to move from reaction to proactive control.
The result is a secure, evidence-based foundation for ongoing data protection and compliance.
“For the first time we can see where sensitive data is really being shared and why. The report helped us focus our controls on the areas that matter most to regulators and clients.”
— Head of Information Security, Financial Services Group
“The assessment exposed data sharing we didn’t know was happening between teams and suppliers. We left with clear actions that reduced our exposure without slowing down production.”
— IT Director, Global Manufacturing Company
“Client data is everything for us. The Health Check helped us see where files were being shared and stored in ways we would never have caught ourselves. We came away with fixes that actually work in a busy legal practice.”
— Compliance Manager, UK Law Firm
“After a near miss we needed to know where personal and tenant data was exposed. The Health Check gave us exactly that, as well as a realistic plan we could deliver with the people and tools we already have.”
— Head of Governance, Housing Association
See where your data is most at risk and how to fix it. CloudGuard’s experts will help you uncover hidden exposures, strengthen protection and get more value from the Microsoft tools you already own.
Unlike a generic audit, this service uses Microsoft Purview’s native capabilities to analyse real collaboration patterns across Exchange, SharePoint, Teams and OneDrive. It focuses specifically on data protection and insider risk, not just policy compliance.
No. The Health Check runs entirely in audit-only mode, meaning no configurations are altered. Your environment remains untouched while data and policy insights are gathered safely.
No. One of the key advantages of this service is that it works with Microsoft 365 Business Premium and E3 licences. CloudGuard helps you maximise the value of what you already own before recommending any licence upgrades.
Typically, the process spans around three weeks. The first few days are used to configure Purview audit policies, followed by a two-week data collection period and a final week for analysis, reporting and presentation.
You’ll receive a comprehensive report outlining risks, data exposures and misconfigurations, along with a prioritised roadmap of actions. Findings are presented in an executive session with time for questions and planning next steps.
Yes. While the focus is on data risk, the assessment maps results to recognised standards such as GDPR and ISO 27001, providing technical evidence that supports compliance requirements.
The Health Check itself is advisory, but CloudGuard can provide additional professional services to help implement recommended actions, strengthen policies and improve ongoing data protection.
Typically, security or IT administrators with access to Microsoft 365, along with compliance or risk stakeholders who oversee data governance. CloudGuard will confirm required permissions at the start.
Once prerequisites and permissions are confirmed, CloudGuard schedules a short kick-off call to define objectives, timelines and deliverables, then begins the audit-only configuration.
Our cybersecurity experts will assess your organisation’s current security posture, with remediation actions to close any gaps.
