The alert is dead, according to one of our Microsoft Ignite session titles. Your on-call phone would like a word. Find out what replaces it, plus more security sessions, Nov 17-20 in San Francisco. Save your seat: msft.it/6010axiwO #MSIgnite
Security starts at the core. Windows memory integrity helps protect critical system processes by making it harder for malicious software to compromise devices. msft.it/6015aaChF
Agents can go from safe to risky mid-task. Watch Microsoft CVP Yina Arenas demo how new Microsoft 365 and Project Perception capabilities help you adapt.
@trinityahebwa Sounds like a job for a password manager
What if an AI agent accesses data or tools it shouldn’t? Introducing new Microsoft 365 E7 and Project Perception capabilities that help security teams govern agents 24/7: msft.it/6010av6zu
@BenjaminHe_CA Visibility really is the starting point.
@StarkTechEG Great take. An agent’s identity is only part of the picture!
@automater_ai Where Zero Trust really matters!
I recently wrote about why we need to treat models as insider risks, with security controls sitting outside the model itself. Today, we're putting that principle into practice by expanding Project Perception with new capabilities to help continuously assess agent risk, adapt permissions, and contain threats. blogs.microsoft.com/blog/2026/10/1…
@ireteeh Password123 is a hacker’s express lane 🙃
@MSCloud The scale is impressive. Trust makes it possible!
#CybersecurityAwarenessMonth, join @Microsoft Windows Security team this Cybersecurity Awareness Month for some security tips. 🔐 This is a reminder that staying secure starts with the basics including how your device starts up. Every time you turn on your device, you expect it to start safely. Secure Boot checks that the software needed to start your device can be trusted, helping stop malicious software from sneaking in before Windows starts. Learn more → support.microsoft.com/en-us/windows/… @msftsecurity @MicrosoftLearn @MSFTnews @msftsecresponse
This #CybersecurityAwarenessMonth, join us from Microsoft’s Windows Security team as we spotlight built-in protections. First up: Secure Boot - security that starts before Windows does. Learn more: support.microsoft.com/en-us/windows/…
From May through September, Microsoft's FORGE Lab helped discover Windows vulnerabilities assigned 140 CVEs and submitted 155 validated reports across 23 open-source projects. Here's what that taught us about scale: msft.it/6017aognT
@nadeemJsX It has to be part of the everyday development workflow!
New Microsoft Digital Defense Report is out. Less talk about volume, more on how attacks are evolving and which gaps deserve your attention this year. Explore the latest trends: msft.it/6011alEic
@PCS_AnthonyM We’d put identity, permissions and AI access high on the list!
@Ahmed___khaan Cutting corners in this profession will impact more than just yourself
