Data Loss Prevention (DLP) - protection against data loss.

If the nature of your business requires you to work with sensitive data, you are certainly aware of your responsibility to protect it properly. Personal ID numbers, credit card numbers, financial data and all other sensitive personally identifiable information require special protection.

Despite proper training of employees, there is still a risk of unauthorized transmission of this type of data in email correspondence, in documents, or in the Teams application. These types of situations call for smart solutions – and that’s what the Data Loss Prevention service from Microsoft is.

How does Data Loss Prevention work?

DLP is part of Microsoft Information Protection within the Microsoft 365 platform. The service searches for messages, documents and other files containing sensitive data, applying specific rules to them about what can and cannot be done with them. For example, if one of the employees tries to attach a file containing an ID number to an email, DLP will detect the attempt, taking appropriate action – such as displaying a security alert or blocking the activity. Rules for certain situations are determined by the administrator.

With DLP rules, the tool identifies, monitors and automatically protects sensitive information in locations such as:

  • Microsoft 365 services: Teams, Exchange, SharePoint and OneDrive,
  • Office applications: Word, Excel and PowerPoint,
  • Windows 10, Windows 11 and macOS endpoints,
  • Cloud applications from companies other than Microsoft,
  • On-premises file shares and on-premises SharePoint.

Confidential items are identified through in-depth content analysis, rather than just a simple text scan. Data Loss Prevention uses machine learning algorithms and other intelligent methods to identify content.

DLP provides continuous monitoring and application of DLP policies to protect confidential data in Office applications as well as Exchange, SharePoint and OneDrive.

Compliance and user convenience

With DLP, you maintain regulatory compliance without adversely affecting your work.
