Next week, RSAC™ Conference celebrates its 35-year anniversary as a forum that brings the security community together to address new challenges and embrace opportunities in our quest to make the world a safer place for all. As we look towards that milestone, agentic AI is reshaping industries rapidly as customers transform to become Frontier Firms -those anchored in intelligence and trust and using agents to elevate human ambition, holistically reimagining their business to achieve their highest aspirations. Our recent research shows that 80% of Fortune 500 companies are already using agents.1
At the same time, this innovation is happening against a sea change in AI-powered attacks where agents can become "double agents." And chief information officers (CIOs), chief information security officers (CISOs), and security decision makers are grappling with the resulting security implications: How do they observe, govern, and secure agents? How do they secure their foundations in this new era? How can they use agentic AI to protect their organization and detect and respond to traditional and emerging threats?
The answer starts with trust, and security has always been the root of trust. In this agentic era, security must be woven into, and around, every layer of the AI estate. It must be ambient and autonomous, just like the AI it protects. This is our vision for security as the core primitive of the AI stack.
At RSAC 2026, we are delivering on that vision with new purpose-built capabilities designed to help organizations secure agents, secure their foundations, and defend using agents and experts. Fueled by more than 100 trillion daily signals, Microsoft Security helps protect 1.6 million customers, one billion identities, and 24 billion Copilot interactions.2 Read on to learn how we can help you secure agentic AI.
Secure agents
Earlier this month, we announced that Agent 365 will be generally available on May 1. Agent 365-the control plane for agents-gives IT, security, and business teams the visibility and tools they need to observe, secure, and govern agents at scale using the infrastructure you already have and trust. It includes new Microsoft Defender, Entra, and Purview capabilities to help you secure agent access, prevent data oversharing, and defend against emerging threats.
Agent 365 is included in Microsoft 365 E7: The Frontier Suite along with Microsoft 365 Copilot, Microsoft Entra Suite, and Microsoft 365 E5, which includes many of the advanced Microsoft Security capabilities below to deliver comprehensive protection for your organization.
Secure your foundations
Along with securing agents, we also need to think of securing AI comprehensively. To truly secure agentic AI, we must secure foundations-the systems that agentic AI is built and runs on and the people who are developing and using AI. At RSAC 2026, we are introducing new capabilities to help you gain visibility into risks across your enterprise, secure identities with continuous adaptive access, safeguard sensitive data across AI workflows, and defend against threats at the speed and scale of AI.
Gain visibility into risks across your enterprise
As AI adoption accelerates, so does the need for comprehensive and continuous visibility into AI risks across your environment-from agents to AI apps and services. We are addressing this challenge with new capabilities that give you insight into risks across your enterprise so you know where AI is showing up, how it is being used, and where your exposure to risk may be growing. New capabilities include:
Secure identities with continuous, adaptive access
Identity is the foundation of modern security, the most targeted layer in any environment, and the first line of defense. With Microsoft Entra, you can secure access and deliver comprehensive identity security using new capabilities that help you harden your identity infrastructure, improve tenant governance, modernize authentication, and make intelligent access decisions.
Safeguard sensitive data across AI workflows
With AI embedded in everyday work, sensitive data increasingly moves through prompts, responses, and grounding flows-often faster than policies can keep up. Security teams need visibility into how AI interacts with data as well as the ability to stop data oversharing and data leakage. Microsoft brings data security directly into the AI control plane, giving organizations clear insight into risk, real-time enforcement at the point of use, and the confidence to enable AI responsibly across the enterprise. New Microsoft Purview capabilities include:
Defend against threats across endpoints, cloud, and AI services
Security teams need proactive 24/7 threat protection that disrupts threats early and contains them automatically. Microsoft is extending predictive shielding to proactively limit impact and reduce exposure, expanding our container security capabilities, and introducing network-layer protection against malicious AI prompts.
Defend with agents and experts
To defend in the agentic age, we need agentic defense. This means having an agentic defense platform and security agents embedded directly into the flow of work, augmented by deep human expertise and comprehensive security services when you need them.
Agents built into the flow of security work
Security teams move fastest with targeted help where and when work is happening. As alerts surface and investigations unfold across identities, data, endpoints, and cloud workloads, AI-powered assistance needs to operate alongside defenders. With Security Copilot now included in Microsoft 365 E5 and E7, we are empowering defenders with agents embedded directly into daily security and IT operations that help accelerate response and reduce manual effort so they can focus on what matters most.
New agents available now include:
Scale with an agentic defense platform
To help defenders and agents work together in a more coordinated, intelligence-driven way, Microsoft is expanding Sentinel, the agentic defense platform, to unify context, automate end-to-end workflows, and standardize access, governance, and deployment across security solutions.
Strengthen with experts
Even the most mature security organizations face moments that call for deeper partnership-a sophisticated attack, a complex investigation, a situation where seasoned expertise alongside your team makes all the difference. The Microsoft Defender Experts Suite brings together expert-led services-technical advisory, managed extended detection and response (MXDR), and end-to-end proactive and reactive incident response-to help you defend against advanced cyber threats, build long-term resilience, and modernize security operations with confidence.
Apply Zero Trust for AI
Zero Trust has always been built on three principles: verify explicitly, use least privilege, and assume breach. As AI becomes embedded across your entire environment-from the models you build on, to the data they consume, to the agents that act on your behalf-applying those principles has never been more critical. At RSAC 2026, we're extending our Zero Trust architecture, the full AI lifecycle-from data ingestion and model training to deployment agent behavior. And we're making it actionable with an updated Zero Trust for AI reference architecture, workshop, assessment tool, and new patterns and practices articles to help you improve your security posture.
See you at RSAC
If you're joining the global security community in San Francisco for RSAC 2026 Conference, we invite you to connect with us.
