Data Loss Prevention Policies
Microsoft Purview DLP allows you to create customized policies that define how your organization shares and protects sensitive data, without exposing it to unauthorized users. These policies can be tailored to your specific industry, regulatory, and compliance requirements, ensuring that your data remains secure and compliant.
For example, you can create a DLP policy that detects and blocks the sharing of financial records or personally identifiable information (PII) via email or file-sharing platforms. By defining these policies, you can prevent accidental data leaks and ensure that your sensitive information is handled with the utmost care.
Data Loss Prevention Controls
In addition to comprehensive policy-setting capabilities, Microsoft Purview DLP offers a suite of powerful controls to safeguard your data. These include:
- Content Inspection: Analyze the content of emails, documents, and other files to identify sensitive information, such as credit card numbers, social security numbers, or trade secrets.
- Access Restrictions: Limit who can access and share sensitive data, ensuring that it remains within your organization’s secure environment.
- Encryption: Automatically encrypt sensitive data, both at rest and in transit, to prevent unauthorized access.
- Alerts and Notifications: Receive real-time alerts when suspicious activity is detected, allowing you to quickly investigate and address potential data breaches.
By leveraging these robust controls, you can establish a multilayered approach to data protection, empowering your organization to detect, prevent, and respond to data loss threats effectively.
Intelligent Data Protection
Microsoft Purview DLP goes beyond traditional rule-based data protection by incorporating advanced machine learning and artificial intelligence (AI) capabilities. This “intelligent data protection” allows the solution to continuously learn and adapt, identifying new threats and anomalies in real-time.
For example, the AI-powered content analysis engine can detect sensitive information even in unstructured data, such as free-form text within documents or emails. This ensures that your data protection measures remain effective, even as your organization’s data landscape evolves.
Furthermore, the intelligent data protection capabilities can help you streamline your compliance efforts. By automatically classifying and labeling sensitive information, Microsoft Purview DLP can assist in maintaining regulatory compliance, such as with the General Data Protection Regulation (GDPR) or the Health Insurance Portability and Accountability Act (HIPAA).
