Microsoft Security

From graph-based context to build-your-own Microsoft Security Copilot agents, we're introducing a new AI-ready security platform and innovations to empower defenders in the era of agentic AI: msft.it/6010sQNtI #MSSecure

Keep your finger on the pulse and learn how to introduce your organization to the safe and secure world of passkeys with our World Passkey Day blog. 🫆

@AshrafElnashar3 👏👏👏👏👏

@msftsecurity "Securely governed digital workforce" = the entire Week 4 theme. Governed. Observable. Orchestrated. Resilient. Most teams build the agents first and governance later. Agent 365 + Azure AI Foundry lets you do both from day one. This is the right sequence.

Agent 365 is now generally available. Transform AI from a helpful suggestion engine into a securely governed digital workforce that works best for you and your organization.

We're honored to be named an Overall Leader—and Market Leader—in @kuppingercole 2026 Emerging AI SOC report. See how we’re investing in AI and automation to help SOC teams move faster, with more confidence and resilience: msft.it/6013vMRhf

📢 This just in: Microsoft Agent 365 is now available and ready to incorporate your AI agents to your workflow. Now it's easier to streamline your digital workforce and ensure it's secure and protected. Got questions? We covered some FAQs below.

When you ask the right questions, risk reviews help shift security from reactive remediation to a proactive posture. Deputy CISO Rico Mariani shares eight key points to make risk reviews actually useful—and help teams build a plan that drives action over time: msft.it/6010vHIdQ

@ZunaeidHasan007 Hi, apologies for the inconvenience you’re experiencing. To help us assist you better, please send us a DM with details of the issue. twitter.com/messages/compo…

@msftsecurity I am unable to login to my account despite multiple attempts. I have access to my account password, my Gmail address and my phone number. Still the OTP is not coming, and the login is not working when I enter the password. Please help me.

It’d be awfully hard to protect or migrate what you can’t see. Read up on why that thinking is the foundation for quantum readiness: msft.it/6011vEMRl

@OpenAI Learn more about the Secure Future Initiative: msft.it/6010vDq6A

A word from @OpenAI and Microsoft Office of the CISO: AI models are becoming much more capable in cybersecurity, and that progress raises the bar for everyone. As capabilities advance, we're focused on deep collaboration with defenders to make software more resilient. Through initiatives like OpenAI’s Trusted Access for Cyber program and Microsoft’s Secure Future Initiative (SFI), we’re committed to helping customers and the industry use these advanced AI models to improve security outcomes for all. OpenAI and Microsoft have worked closely for years, and we’re building on our partnership. Going forward, our teams will work even more closely to apply AI for defense. OpenAI will provide Microsoft with access to its most cyber capable models through Trusted Access for Cyber, and Microsoft is committed to bringing the full strength of its cybersecurity defense team to help OpenAI protect their models and infrastructure and defend our joint customers. We’re excited to keep raising the bar together and with others in the industry to help make the broader ecosystem, including open-source software, more secure.

Attacks of opportunity work when there’s, well… opportunity. That can be minimized through: ✅ credential elimination ✅ endpoint reduction ✅ identity controls. Ilya Grebnov, Deputy CISO for Microsoft Dynamics 365 and Power Platform shares practices that everyone can pick up right away. Read more: msft.it/6010vDYJs

@phishfinding Thank you for sharing, Wes. Making security feel approachable for everyone is exactly the goal, so we’ll happily take the mom-test usability rating 😌

Microsoft Sentinel is officially the easiest SIEM to learn & use, I am confident I could teach my mom how to use this fairly quickly.

Patches work when failures are predictable. AI isn’t. AI introduces new categories of risk, so incident response can’t rely on the same playbook. Here’s what still works, what doesn’t, and how IR needs to evolve when AI is part of the stack. Learn more: msft.it/6011v6zGt
