Email Security & Data Loss Prevention
Email is still the most common way in, and the most common way data walks out. We manage email security - DMARC/DKIM/SPF enforcement, phishing and malware filtering - alongside Data Loss Prevention (DLP) policies that catch sensitive data leaving via email, file-sharing and, increasingly, AI tools.

Overview
Email is still the most common way in, and one of the most common ways data walks out. We manage email authentication and filtering alongside Data Loss Prevention (DLP) policies that catch sensitive data leaving via email, file-sharing and AI tools - coordinated with our AI Activity & Data Leak Monitoring service rather than run as a separate silo.
At a glance
- DMARC/DKIM/SPF enforced to stop domain spoofing
