The most valuable ones tell us where to improve next.<\/strong> <\/h2>\n<p class=\"wp-block-paragraph\">For five consecutive quarters Microsoft has published email security benchmarking reports to provide greater transparency into real-world protection outcomes. The results have shown strong <a href=\"https:\/\/www.microsoft.com\/en-us\/security\/business\/siem-and-xdr\/microsoft-defender-office-365\" target=\"_blank\" rel=\"noopener noreferrer\">Microsoft Defender<\/a> performance across pre-delivery and post-delivery scenarios, while revealing where threats and defenses continue to evolve.<\/p>\n<p class=\"wp-block-paragraph\">This quarter\u2019s benchmark examines how continuous measurement informs protection across prevention, detection, and adaptation, and how those insights are helping improve customer outcomes.<\/p>\n<h2 class=\"wp-block-heading\" id=\"key-takeaways\">Key takeaways<\/h2>\n<ul class=\"wp-block-list\">\n<li class=\"wp-block-list-item\">Defender again missed the fewest high-severity threats among the solutions evaluated, about <strong>55% fewer<\/strong> than the next-closest secure email gateway (SEG) vendor.<\/li>\n<li class=\"wp-block-list-item\">Layered security adds the most value in promotional and bulk filtering and works; gains for spam and malicious email remain comparatively modest.<\/li>\n<\/ul>\n<h2 class=\"wp-block-heading\" id=\"benchmarking-results-for-seg-vendors\"><strong>Benchmarking results for SEG vendors<\/strong><\/h2>\n<p class=\"wp-block-paragraph\">In the latest quarterly SEG comparison from May 2026 through July 2026, Defender missed 221 high-severity threats per 1,000 protected users, 55.4% fewer than the next-closest SEG vendor. The benchmark measures missed threats instead of the total number of malicious emails that were caught and filtered, because catch totals can reflect differences in threat volume and exposure across vendor environments. By normalizing missed threats per 1,000 users we are able to provide a more consistent side-by-side comparison.<\/p>\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;6aacf2a54344a&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"6aacf2a54344a\" class=\"wp-block-image size-full wp-lightbox-container\"><img decoding=\"async\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/www.microsoft.com\/en-us\/security\/blog\/wp-content\/uploads\/2026\/09\/Picture1.webp\" alt=\"The image shows a bar chart illustrating the number of high severity email threats that were missed by various Secure Email Gateway (SEG) vendors, with Mimecast leading the list.\" class=\"wp-image-149416 webp-format\" srcset data-orig-src=\"https:\/\/www.microsoft.com\/en-us\/security\/blog\/wp-content\/uploads\/2026\/09\/Picture1.webp\"><button class=\"lightbox-trigger\" type=\"button\" aria-haspopup=\"dialog\" aria-label=\"Enlarge\" data-wp-init=\"callbacks.initTriggerButton\" data-wp-on--click=\"actions.showLightbox\" data-wp-style--right=\"state.imageButtonRight\" data-wp-style--top=\"state.imageButtonTop\"> <svg width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\"> <path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/> <\/svg> <\/button><figcaption class=\"wp-element-caption\">Figure 1: High-severity email threats missed by SEG vendors (May 2026 through July 2026), measured as threats missed per 1,000 users protected. Data source: Microsoft Defender.<\/figcaption><\/figure>\n<p class=\"wp-block-paragraph\">If you\u2019ve read our previous blogs, you\u2019ll see that missed threats have increased across multiple reporting periods, including for Microsoft. This aligns with broader trends we\u2019re seeing as AI makes it easier for cyberattackers to gather public information, tailor messages, and create more convincing impersonation attempts. It reinforces the need for protection that continuously adapts.<\/p>\n<h2 class=\"wp-block-heading\" id=\"benchmarking-results-for-ices-vendors\"><strong>Benchmarking results for ICES vendors<\/strong><\/h2>\n<p class=\"wp-block-paragraph\">Effective email detection combines pre-delivery filtering with post-delivery detection and remediation. This benchmark helps customers evaluate where each layer contributes measurable value.<\/p>\n<p class=\"wp-block-paragraph\">Similarly to previous quarters, integrated cloud email security (ICES) solutions continue adding the most value in promotional and bulk filtering. We saw an improvement in ICES vendor malicious catch at 0.30% versus 0.13% in the last quarter and spam catch going up to 0.52% versus 0.28% compared to last quarter. <\/p>\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/www.microsoft.com\/en-us\/security\/blog\/wp-content\/uploads\/2026\/09\/Picture2.webp\" alt=\"The diagram illustrates the distribution of different types of cyber threat catches (non-malicious, spam, and malicious) detected by various vendors (Check Point, Cisco, Darktrace, etc.) in Microsoft Defender Counter Attack (ICES) from May to July 2026.\" class=\"wp-image-149417 webp-format\" srcset data-orig-src=\"https:\/\/www.microsoft.com\/en-us\/security\/blog\/wp-content\/uploads\/2026\/09\/Picture2.webp\"><figcaption class=\"wp-element-caption\">Figure 2: ICES vendor catch contribution (May 2026 through July 2026). Data source: Microsoft Defender.<\/figcaption><\/figure>\n<p class=\"wp-block-paragraph\">Defender caught 92% of post-delivery malicious messages on average during the benchmark period, highlighting how the combination of pre-delivery and post-delivery remediation delivers strong results for customers.<\/p>\n<p class=\"wp-block-paragraph\">At the same time it\u2019s key to understand that Defender doesn\u2019t treat post-delivery remediation as a point-in-time action after the email was first delivered to the inbox. Even after a message reaches the inbox, new threat intelligence can reveal risks that were not apparent at the time of delivery. Defender continuously reevaluates delivered messages and remediates threats as new indicators, campaign intelligence, and threat signals emerge.<\/p>\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;6aacf2a545601&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"6aacf2a545601\" class=\"wp-block-image size-full wp-lightbox-container\"><img decoding=\"async\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/www.microsoft.com\/en-us\/security\/blog\/wp-content\/uploads\/2026\/09\/Picture3-1.webp\" alt=\"The image is a pie chart showing the percentage of malicious emails detected by various security vendors, with Microsoft Defender catching the most at 92%.\" class=\"wp-image-149419\"><button class=\"lightbox-trigger\" type=\"button\" aria-haspopup=\"dialog\" aria-label=\"Enlarge\" data-wp-init=\"callbacks.initTriggerButton\" data-wp-on--click=\"actions.showLightbox\" data-wp-style--right=\"state.imageButtonRight\" data-wp-style--top=\"state.imageButtonTop\"> <svg width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\"> <path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/> <\/svg> <\/button><figcaption class=\"wp-element-caption\">Figure 3: Post\u2011delivery malicious catch by Microsoft Defender (May 2026 through July 2026), shown across vendors and overall average.

Insights from customer feedback, threat telemetry, and benchmarking have informed recent Microsoft Defender investments:<\/p>\n<ul class=\"wp-block-list\">\n<li class=\"wp-block-list-item\"><strong>More control over promotional mail<\/strong>: Across multiple benchmarking periods, we observed that ICES solutions often delivered the greatest incremental benefit in filtering promotional and bulk email. The new <a href=\"https:\/\/techcommunity.microsoft.com\/blog\/microsoftdefenderforoffice365blog\/declutter-and-defend-reducing-promotional-mail-noise-with-microsoft-defender\/4511732\" target=\"_blank\" rel=\"noopener noreferrer\">Promotions folder<\/a> in Outlook builds on these insights by helping users reduce inbox clutter while keeping legitimate marketing and bulk messages accessible.<\/li>\n<li class=\"wp-block-list-item\"><strong>Redesigned machine learning and AI model stack<\/strong>: By analyzing and incorporating natural language processing signals, including message topic, alongside other AI detection signals, Defender can improve detection accuracy. During a consecutive four-week period, Microsoft research observed a roughly two-thirds reduction in false negatives and a nearly one-fifth reduction in false positives for Defender customers. <\/li>\n<li class=\"wp-block-list-item\"><strong>Protection for people and AI<\/strong>: We built <a href=\"https:\/\/techcommunity.microsoft.com\/blog\/microsoftdefenderforoffice365blog\/defending-the-inbox-against-prompt-injection-attacks\/4534636\" target=\"_blank\" rel=\"noopener noreferrer\">prompt injection protection<\/a> to detect and isolate malicious AI instructions in email before delivery\u2014helping protect not only people, but also Copilot, agents, and other AI systems that read and act on inbox content. This innovation demonstrates how we continue evolving our defenses to address the latest cyberattack techniques and stay ahead of emerging threats.<\/li>\n<\/ul>\n<h2 class=\"wp-block-heading\" id=\"looking-ahead\"><strong>Looking ahead<\/strong><\/h2>\n<p class=\"wp-block-paragraph\">Since July 2025, our goal has been to bring greater transparency to email security effectiveness. Today, we are using benchmarking to help customers understand how cyberthreats evolve, where defenses add value, and how protection improves over time.<\/p>\n<p class=\"wp-block-paragraph\">Benchmarking is not simply about demonstrating effectiveness, it is about learning from real-world outcomes and translating those insights into stronger protection. As cyberattackers continue to innovate, we remain committed to sharing evidence, improving our technology, and helping customers stay ahead of emerging cyberthreats.<\/p>\n<p class=\"wp-block-paragraph\">To explore the latest benchmarking data and learn more about how Defender and ICES partners work together, access the <a href=\"https:\/\/www.microsoft.com\/security\/business\/siem-and-xdr\/microsoft-defender-office-365\/performance-benchmarking\" target=\"_blank\" rel=\"noreferrer noopener\">benchmarking site<\/a>.<\/p>\n<h2 class=\"wp-block-heading\" id=\"learn-more\">Learn more<\/h2>\n<p class=\"wp-block-paragraph\">Learn more about <a href=\"https:\/\/www.microsoft.com\/en-us\/security\/business\/siem-and-xdr\/microsoft-defender-office-365\" target=\"_blank\" rel=\"noreferrer noopener\">Microsoft Defender<\/a>.<\/p>\n<p class=\"wp-block-paragraph\">To learn more about Microsoft Security solutions, visit our <a href=\"https:\/\/www.microsoft.com\/en-us\/security\/business\" target=\"_blank\" rel=\"noreferrer noopener\">website.<\/a> Bookmark the <a href=\"https:\/\/www.microsoft.com\/security\/blog\/\" target=\"_blank\" rel=\"noreferrer noopener\">Security blog<\/a> to keep up with our expert coverage on security matters.
