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.
"A departing employee copying client files in bulk is one of the most common — and most preventable — data incidents. DLP catches the pattern in real time."Classification firstPolicy enforcement follows the data, wherever it goes
Staff or attackers copy sensitive data to personal email, USB, or unsanctioned cloud. Endpoint and email DLP block it in real time.
Sensitive data hides in personal drives, old test systems, and unsanctioned SaaS. Discovery scans bring it under control.
Accidental or deliberate emailing of sensitive files creates GDPR exposure. Outbound inspection blocks, quarantines, or warns.
Uncontrolled USB ports bypass every network control. Device policies restrict, monitor, and enforce encryption.
Misconfigured SharePoint and Teams settings expose documents externally. Classification-based sharing restrictions prevent it.
Bulk downloads before resignation go unnoticed for weeks. Activity monitoring alerts on the pattern as it happens.
A practical classification framework with Microsoft Purview or Varonis sensitivity labels driving policy enforcement.
Endpoint, email, and cloud DLP matching sensitive content patterns — block, quarantine, audit, or justified override.
BitLocker, TLS, database encryption, and key management via Azure Key Vault or AWS KMS — with audit evidence.
Microsoft 365 or Google Workspace outbound inspection, attachment encryption, and external sharing controls.
Locate PII, payment data, and health records across file servers, SharePoint, and cloud storage — then bring it under control.
Microsoft Information Protection labels that travel with documents — enforcing encryption wherever files go.
