Sophos Central DMARC Manager Add-on for Email Advanced | 1,000-1,999 Users

Protect trusted email channels at enterprise scale with Sophos Central DMARC Manager Add-on for Email Advanced. Built for organizations with 1,000-1,999 users, this add-on supports long-term DMARC management over a 59-month term, giving security and messaging teams a structured way to improve domain authentication discipline. For larger user populations, email abuse is rarely a single-point problem. Spoofed messages can erode trust, trigger help desk noise, and expose users to credential theft. This add-on helps centralize DMARC oversight so teams can track authentication outcomes, tighten policy enforcement, and maintain visibility into how their domain is being used across the mail ecosystem. The value is in control and consistency. Instead of relying on ad hoc checks or manual policy changes, teams get a cleaner path to managing domain protection across a broad user base. That matters when email remains a primary attack surface and when the cost of a misrouted or impersonated message is measured in more than just downtime. For organizations standardizing on Sophos, this add-on extends the platform with a focused layer for email authentication governance.
