Consider switching to Proofpoint: Proofpoint offers similar email security features with a focus on advanced threat protection and compliance.
On April 22, 2026, Sophos renamed "Central Email Advanced" to simply "Sophos Email" and announced a new Sophos Email Plus premium tier launching April 29, 2026. Product codes and SKUs are unchanged; only the license descriptions and marketing collateral are updated, so existing customer contracts and renewals are unaffected. Sophos Phish Threat simulation and security awareness training was bundled into Sophos Email in December 2025, which was previously a separate add-on license. The DMARC Manager Add-On and Portal Encryption Add-On were also renamed to drop the "Central" prefix.
Proofpoint Essentials publishes transparent pricing starting at $3.03 per user per month for Business tier up to $5.86 per user per month for Professional, while Sophos Email is quote-based at an estimated $33-$50 per user per year. Gartner Peer Insights gives Sophos Email 4.8 out of 5 with 362 reviews versus Proofpoint at 4.6 out of 5 with 1,398 reviews, reflecting Sophos's smaller market footprint but higher satisfaction. Sophos Email bundles Phish Threat simulation and training at no extra cost, while Proofpoint sells Security Awareness Training as a separate SKU. Pick Proofpoint if you want published SMB pricing today, pick Sophos Email if you value KuppingerCole Leader validation and integration with Sophos MDR for clawback during active threats.
Mimecast is priced at $5-$15 per user per month and bundles enterprise archiving, eDiscovery, and 99.999% email continuity SLA as core capabilities. Sophos Email at an estimated $33-$50 per user per year is cheaper on a per-user basis but has thinner archiving and continuity features. Mimecast customers commonly report steep renewal price increases and aggressive sales tactics, while Sophos Email's channel-based sales model tends to produce more stable renewal pricing. Pick Mimecast if archiving and eDiscovery are the primary requirements, pick Sophos Email if threat detection and bundled phishing simulation matter more.
Microsoft Defender for Office 365 Plan 2 is included at no marginal cost in Microsoft 365 E5 at $57 per user per month and extends protection to Teams, SharePoint, and OneDrive natively, which Sophos Email does not. Sophos Email adds 20+ AI and ML models including NLP for deeper BEC detection, manual message clawback orchestrated by Sophos MDR, and bundled Phish Threat simulation, all of which strengthen the email-specific defense layer. Many mid-market buyers on E5 run both: Defender for baseline EOP coverage and Sophos Email as the API-integrated second layer. If budget is the constraint and you are already on E5, Defender alone is defensible; if budget allows both, Sophos Email's NLP-driven BEC catch rate is the differentiator.
Sophos Email is the base tier covering core email threat protection, Phish Threat simulation, Time-of-click URL protection, and M365 or Google Workspace API integration at an estimated $33-$50 per user per year. Sophos Email Plus launches April 29, 2026 at an estimated $50-$75 per user per year and adds enhanced message handling capabilities plus the DMARC Manager Add-On bundled into the license. Sophos has signaled that additional features will be added to Plus in future releases to further differentiate it from the base tier. Buyers deploying Sophos Email for the first time after April 29, 2026 should evaluate both tiers, since DMARC conformance is increasingly required for bulk senders by Google and Yahoo.
Clawback uses the Microsoft Graph API to pull messages out of user mailboxes after delivery if Sophos Email or Sophos MDR later identifies the message as malicious. This matters because modern phishing attacks use clean URLs at delivery time that get weaponized hours or days later, and Time-of-click URL protection alone cannot remove messages already sitting in inboxes. The integration with Sophos MDR is what KuppingerCole called "standout" in the 2025 Leadership Compass, since MDR analysts can execute clawback as a real-time response action during an active incident. Clawback requires the M365 API integration to be enabled during onboarding.
Sophos Email Monitoring System is a complement, not a replacement. EMS is a detection-only security sensor designed to sit alongside an existing Proofpoint, Mimecast, or Microsoft Defender for Office 365 deployment and catch threats that slip through the incumbent gateway. EMS integrates with Sophos MDR and Sophos XDR so that email threat data feeds into the cross-product data lake for unified SOC visibility without replacing the production email flow. Organizations that are contractually locked into an incumbent SEG, or unwilling to take on the change management of a rip-and-replace, use EMS to gain Sophos's 20+ AI and ML model detection as a second layer.
Yes. On April 14, 2025, Sophos disclosed in incident INC-2025-001 that a logic flaw in Sophos Email's outbound relay validation let trial accounts send approximately 1.9 million non-malicious spam messages, including 30 messages that impersonated 12 paying Sophos Email customer domains. Sophos blocked the abusing accounts and IPs within hours, pushed the policy fix to production within 24 hours, and disabled outbound relay for all future trial accounts by April 19, 2025. Affected paying customers were notified directly by Sophos Support, and Sophos published a detailed root cause analysis on the Sophos Trust site while crediting the Reddit user who surfaced the issue under the bug bounty program.
Yes. Sophos Email is available to MSPs through Sophos Central Partner for multi-tenant management and through MSP Flex for monthly usage-based licensing that matches managed-services billing cadences. The new Sophos Email Plus tier will be available to sell on both term license and MSP Flex starting April 29, 2026. MSPs managing multiple downstream customer environments (called Beneficiaries in Sophos legal documents) can apply tier selection on a per-customer basis within the same partner console. Partner portal access is required to see the current MSP price list.
