Stop sensitive data leaving — by accident or by design

Data Loss Prevention encompasses the policies, tools, and processes that stop sensitive data leaving your organisation without authorisation — whether through email, removable media, cloud uploads, or deliberate exfiltration.

A mature programme protects data in all three states: at rest (encryption and access control on storage), in transit (TLS and DLP inspection on networks and email), and in use (endpoint controls and activity monitoring). These map directly to GDPR Article 32 technical measures and ISO 27001 Annex A.8.

P2P CyberDefence designs and deploys proportionate data security programmes built on Microsoft Purview, Varonis, and the native capabilities you already license.

Challenges We Address

Data loss risks we prevent

Data Exfiltration

Staff or attackers copy sensitive data to personal email, USB, or unsanctioned cloud. Endpoint and email DLP block it in real time.

Shadow Data Stores

Sensitive data hides in personal drives, old test systems, and unsanctioned SaaS. Discovery scans bring it under control.

Email Attachment Leakage

Accidental or deliberate emailing of sensitive files creates GDPR exposure. Outbound inspection blocks, quarantines, or warns.

Removable Media

Uncontrolled USB ports bypass every network control. Device policies restrict, monitor, and enforce encryption.

Cloud Over-Sharing

Misconfigured SharePoint and Teams settings expose documents externally. Classification-based sharing restrictions prevent it.

Insider Exfiltration

Bulk downloads before resignation go unnoticed for weeks. Activity monitoring alerts on the pattern as it happens.

What We Deliver

Our data security services

Data Classification & Labelling

A practical classification framework with Microsoft Purview or Varonis sensitivity labels driving policy enforcement.

DLP Policy Deployment

Endpoint, email, and cloud DLP matching sensitive content patterns — block, quarantine, audit, or justified override.

Encryption Implementation

BitLocker, TLS, database encryption, and key management via Azure Key Vault or AWS KMS — with audit evidence.

Email DLP

Microsoft 365 or Google Workspace outbound inspection, attachment encryption, and external sharing controls.

Data Discovery Scans

Locate PII, payment data, and health records across file servers, SharePoint, and cloud storage — then bring it under control.

Information Protection

Microsoft Information Protection labels that travel with documents — enforcing encryption wherever files go.
