Your client files, financials, and employee records live in Microsoft 365. Protek uses the Microsoft Purview tools you may already own to find that data, label it, and keep it from leaking, whether it’s headed to the wrong inbox or into an AI tool.

Data governance sounds like something only large enterprises need. In practice, it comes down to four questions: What sensitive data do we have? Where is it? Who can get to it? What happens when someone tries to send it somewhere it shouldn’t go?
For most small and mid-sized businesses, the honest answer is “we’re not sure.” After a few years in Microsoft 365, client files end up in personal OneDrive folders. Payroll spreadsheets get emailed back and forth. SharePoint sites get shared with “everyone” to save time, and old “anyone with the link” shares never expire.
DLP turns good intentions into rules your systems enforce. Because Microsoft Purview is built into Microsoft 365, many businesses already pay for much of it.
Our Partners
Purview is a family of tools. We start with what you're licensed for and add only what solves a real problem.
Labels like Public, General, Confidential, and Highly Confidential tell people and systems how sensitive a file or email is. A label can add headers, footers, watermarks, and encryption.
DLP watches Exchange email, SharePoint, OneDrive, and Teams. Purview can show a tip, block an action, allow a business-reason override, or alert administrators.
Purview finds sensitive content using built-in types, custom types such as client numbers, exact data match, and trainable classifiers.
Extends DLP to Windows and macOS. It can restrict copying to USB, uploading to unapproved clouds, or pasting into restricted websites and AI sites.
With the right licensing, this looks for risky patterns such as a departing employee downloading large amounts of data or risky AI use.
DSPM surfaces oversharing risk, shows sensitive data in AI interactions, and recommends policies that keep labeled data out of Copilot.
Review alerts, tune rules, and keep Purview controls aligned with your business.
We follow the same Stabilize → Secure → Modernize approach we use for everything else. Discovery comes first, enforcement comes last, and nobody gets surprised.
We confirm licenses, interview finance, HR, operations, and client services, then use Purview to map where sensitive data lives, how it is shared, and what is open too broadly.
We design a short label set, write a one-page guide, fix the worst oversharing, and set up default or automatic labeling where licensing allows.
We build policies for outbound email, external sharing, USB drives, and AI prompts. Every policy starts in simulation mode; we tune false positives and enable tips before blocking.
We review alerts and matches, tune rules as workflows change, and track new Purview and Copilot features.

AI tools are only as safe as the data they can reach. Microsoft 365 Copilot only surfaces organizational data each person already has permission to see. If HR files are open to everyone, Copilot can find and summarize them.
Purview provides several layers:
Our AI Enablement program covers policy, licensing, and training.
Whether you are getting ready for Copilot or answering a client security questionnaire, Protek can help put sensible data protection in place without slowing your team down.

Discovery and testing come before enforcement. We check licensing in Step 1 and explain plainly what an upgrade would add.
| Mistake | What goes wrong | Our approach |
|---|---|---|
| Blocking on day one | Work gets stuck. | Simulation first, staged enforcement. |
| Too many labels | People cannot tell them apart. | A short, plain-language label set. |
| Ignoring permissions | AI still finds overshared files. | Clean up oversharing before Copilot controls. |
| Assuming your license covers everything | Advanced controls need higher tiers. | Review licensing in Step 1. |
Business Premium, E3, or Office 365 E3 include manual labels and DLP for Exchange, SharePoint, and OneDrive. E5 or advanced Purview add-ons add automatic labeling, Teams chat DLP, Endpoint DLP, and Copilot label blocking. Browser DLP and network-level DLP may be pay-as-you-go extras. Microsoft changes packaging often; this is a guide, not a quote.
DLP policies and tools keep sensitive information from being shared with people who should not have it. Purview inspects Exchange, SharePoint, OneDrive, Teams, and company devices and can warn, block, or alert.
Yes. Small businesses hold client records, financial information, and employee details, often with fewer people watching over it. DLP lowers the chance a mis-sent email or overshared folder becomes an incident.
Yes. Copilot only surfaces data each user already has permission to see. When a label encrypts content, Copilot returns it only to users whose rights include viewing and extracting it.
On managed Windows devices, Endpoint DLP can warn or block pastes and uploads to third-party AI websites. Edge for Business can also apply DLP to AI apps.
Business Premium and E3 include manual labels and DLP for Exchange, SharePoint, and OneDrive. Automatic labeling, Teams chat, Endpoint DLP, and Copilot controls require E5 or an add-on.
Not if rolled out carefully. Every policy starts in simulation mode, then we adjust rules and enable policy tips before anything is blocked.
It depends on data volume, locations, and policies. Most time goes into discovery and simulation testing; after Discover we give you a timeline based on what we found.
A label classifies and can protect a file, email, or site. A DLP policy watches what people do with sensitive information and steps in when a rule is broken. They work best together.
