Introducing Extended Email Security
Grzegorz Nocoń · 2026-04-15 · via Business Insights Cybersecurity Blog by Bitdefender

Email remains the primary vector for cyberattacks. Attackers favor "low and slow" tactics—highly targeted spear-phishing, sophisticated brand impersonation, and supply chain fraud. To close these gaps, organizations need more than just a filter at the front door; they require deep visibility inside the mailbox and the ability to act even after an email has been delivered.

Bitdefender Extended Email Security, integrated into the GravityZone console, provides enterprise organizations and MSPs with the deep mailbox visibility and forensic tools required to intercept threats that bypass traditional perimeter defenses.

A Modular Architecture for Diverse Environments

Every organization’s email infrastructure is unique, which is why Extended Email Security offers a modular deployment model. Rather than forcing a "one-size-fits-all" approach, you can choose the architecture that best aligns with your specific risk profile and infrastructure:

  • Gateway: A platform-agnostic solution that sits at the network edge. By changing MX records, all inbound emails are routed to the gateway for filtering before they reach your mailbox server.

  • API-Based: Designed exclusively for Microsoft 365, this model requires no MX record changes. It utilizes a secure API to inspect messages directly in the user's mailbox.

  • Unified: For organizations requiring the highest level of security, the Unified model combines both Gateway and API capabilities for both perimeter protection and post-delivery remediation.

Streamlined Management and Deep Forensic Visibility

Extended Email Security provides administrators with real-time telemetry and deep-dive forensic visibility through the Live Email Tracker. This tool provides total visibility over all email traffic—including inbound, outbound, and internal messages—with access levels tailored to the viewer's specific role. At the MSP Level, you maintain central visibility across all your customers, enabling you to search for malware and phishing attempts across your entire client base at once. At the Customer Level, you view traffic specific to your individual account for localized response, while at the End-User Level, users can monitor traffic for their own mailboxes to stay informed.

With 90 days of retained records in the Live Email Tracker, your security teams can perform granular searches based on metadata, subject lines, or authentication results (SPF, DKIM, DMARC).

While these detailed forensic logs are kept for three months, quarantined emails are held for 28 days, giving administrators and users a focused window to release or delete suspicious messages. This transparency allows you to see exactly why a message was quarantined or delivered. By leveraging Bitdefender Malware Protection, Antispam, and Sandbox Analyzer, the system neutralizes over 99% of threats at the inbound stage.

Threat actors often use "time-bombed" URLs—links that appear clean during initial scanning but are weaponized hours later. Extended Email Security addresses this through Auto-Remediation.

For API and Unified deployments, the system continues to monitor emails for 48 hours after delivery. If a link is later identified as malicious, the system can automatically remove the email from the user's mailbox. Beyond automation, administrators can manually trigger the Remediate action directly from the Live Email Tracker. For MSPs, the Remediate action allows you to execute a single command to remove a specific threat across multiple client tenants.

To reduce helpdesk overhead and empower the workforce, automated Quarantine Digests allow users to safely preview low-risk mail and manage their own allow/block lists.

Summary

Bitdefender Extended Email Security provides enterprise organizations and MSPs with a unified defense against targeted campaigns, spear-phishing, and supply chain fraud. By combining real-time telemetry with automated remediation, administrators can identify and neutralize evasive threats before they impact the business.
