Sophos Email is a cloud-based email security platform from Sophos, delivered through the Sophos Central management console, that protects organizations from sophisticated email-based threats including phishing, business email compromise, impersonation attacks, malware, ransomware, and data exfiltration. The platform uses AI-powered multi-layered threat detection with over 20 machine learning models, including natural language processing, to identify and block threats before they reach users' inboxes, with post-delivery remediation capabilities that can remove malicious emails after delivery if needed.
Sophos Email integrates with Microsoft 365 and Google Workspace through API-based deployment, meaning it does not require changes to your MX records or email routing. This makes it straightforward to deploy without disrupting existing email flow. The platform includes Time-of-Click URL rewriting that re-checks links when users click them, advanced attachment sandboxing for zero-day protection, and QR code detection to block emerging phishing techniques. Additional capabilities include DMARC Manager for authentication monitoring, Data Loss Prevention (DLP) with multi-rule policies, email encryption options (S/MIME, TLS, portal encryption), and integration with Sophos Phish Threat for phishing simulations and security awareness training.
Sophos Email is managed entirely from the Sophos Central console, which also manages endpoint protection, firewall, and network security products, allowing MSPs to centralize management across security domains. The platform suits MSPs protecting Microsoft 365 or Google Workspace environments who want advanced threat detection, user training integration, and post-delivery remediation without vendor lock-in. Pricing is not published on Sophos's website; third parties cite approximately $2 to $6 per mailbox per month or $28 to $75 per user per year depending on feature tier and volume, with annual billing standard (checked September 2026). Sophos is based in the United Kingdom and has been providing endpoint and network security solutions since 1985, with deep integration available between Sophos Email and Sophos MDR and XDR services for coordinated threat response.
Sophos Email stands out for its API-based deployment with Microsoft 365 and Google Workspace, avoiding MX record changes and simplifying setup compared to gateway-based alternatives like Mimecast or Proofpoint Essentials. The platform suits MSPs managing multi-cloud environments who want centralized threat management without re-routing email. Post-delivery remediation and automatic clawback distinguish Sophos Email from inline-only competitors. Before purchasing, confirm that your email environment aligns with Sophos's API-first approach, and evaluate whether the integrated Phish Threat training component meets your security awareness needs. MSPs heavily invested in Sophos endpoint or firewall products will find value in unified Sophos Central management, but those seeking gateway-only deployment should explore traditional email gateway alternatives.

The trial includes Sophos Email's threat detection, post-delivery remediation, and API-based integration with Microsoft 365 or Google Workspace at no charge for the trial period.
Sophos Email integrates with both Microsoft 365 and Google Workspace through API-based deployment, where Sophos Email connects directly to your email platform without changing MX records or email routing. Both platforms are equally supported via Sophos Central. Sophos Email also offers gateway-based deployment as an alternative for organisations requiring traditional pre-delivery filtering, though API-based integration is the primary approach and the one that avoids mail flow disruption.
Sophos Email differentiates through its API-first approach for Microsoft 365 and Google Workspace, which avoids MX record changes and simplifies deployment compared to gateway-based solutions. It includes post-delivery clawback that removes malicious emails from inboxes after detection. Sophos Email integrates with Sophos Phish Threat for built-in security awareness training and with Sophos MDR for coordinated threat response, providing end-to-end threat management without separate vendor configuration.
Sophos Email Plus, launched in April 2026, adds several premium capabilities compared to the core Sophos Email tier. These include an Emergency Inbox that keeps users productive during cloud email provider outages by providing 24/7 access to queued messages for up to 90 days, outbound DKIM support for additional authentication capabilities, and advanced message handling options. The Plus tier suits larger MSPs or organisations requiring maximum redundancy and authentication controls.
