We don’t just say it works—we show it, quarter over quarter.
New email security benchmarking data is out now—built on real-world telemetry, not synthetic tests.
The TL;DR:
➡️ Microsoft Defender consistently misses fewer high-severity cyberthreats than any SEG vendor evaluated
➡️ ICES vendors deliver the most value in promotional and bulk email filtering
➡️ Defender now drives the majority of post-delivery remediation
See what other insights a year’s worth of data reveals: msft.it/6019vcmHF
ALT Bar chart comparing high severity email threats missed by Secure Email Gateway (SEG) vendors from February to April 2026. Text reads: “High severity email threats missed* by Secure Email Gateway (SEG) vendors, February – April 2026.” Microsoft Defender shows 194 missed threats, while other vendors display higher values: Mimecast 478, ProofPoint 483, HornetSecurity 813, TrendMicro 1,151, IronPort 1,274, Barracuda 1,585, and FireEye 2,107. A note explains that SEG vendor misses are threats detected after passing through the gateway.

500M monthly players across Xbox consoles, PC, handheld, and cloud gaming. 🎮
That’s a lot to protect, but gaming goes far beyond accounts and devices.
Gaming culture runs deep, spanning players, developers, platforms, and the teams behind it all—and each brings its own security challenges.
Hear from Deputy CISO Aaron Zollman on how we secure it all: msft.it/6011vnKQX

AI safety should be continuous, not a checkpoint.
Announcing two new open-source tools to help engineers build safety in from the start:
➡️ RAMPART: turn red-team techniques into repeatable, CI-ready tests
➡️ Clarity: validate what you should build before writing code
Bringing the focus back to the “why,” not just the “how.”

DDoS attacks are on the rise.
Solving them starts with stepping back—and going deep on defense. What that looks like:
➡️ Make abnormal traffic easier to spot and harder to exploit with rate limiting, geo-fencing, and anomaly detection
➡️ Design for graceful degradation: maintain core functionality, even when systems are stressed
