The Imperative: Agents and the Skills Gap
The cybersecurity landscape has reached a historic inflection point. As cyberattackers wield generative AI to automate attacks at speed and scale, the defense must become equally agentic. Relying solely on human resources is insufficient, especially given the daunting challenge of over four million unfilled cybersecurity jobs globally.
The solution is empowering security professionals with intelligent agents and AI collaborators designed to enhance human expertise and transform organizational security. This is why Microsoft is delivering agents right into the everyday flow of work, embedded in the tools security teams already use.
The Imperative: Agents and the Skills Gap
As AI adoption accelerates, managing these intelligent collaborators becomes critical. With IDC predicting there will be 1.3 billion agents by 2028, security leaders urgently need a strategy to manage, govern, and secure this new workforce.
The pivotal Microsoft Ignite announcement addressing this is Microsoft Agent 365, the control plane for AI agents. Agent 365 extends trusted organizational infrastructure to manage agents, regardless of whether they were created using Microsoft tools, open-source frameworks, or third-party platforms.
Agent 365 unites intelligence, security, and governance through five core capabilities:
Registry
Provides a single source of truth for all organizational agents, which allows IT leaders to get a complete inventory and the ability to quarantine unsanctioned “shadow agents”.
Access Control
Manages agent access to resources, enforcing adaptive access policies and blocking compromised agents from organizational resources based on real-time context and risk using Agent Policy Templates.
Security
Delivers comprehensive protection by natively leveraging Microsoft Defender, Microsoft Entra, and Microsoft Purview. This includes protection against AI cyberattacks (like prompt injections), detection of vulnerabilities, and prevention of sensitive data leakage.
Visualization
Offers a unified dashboard and advanced analytics to map connections between agents, users, and resources, helping leaders monitor agent behavior and performance in real time.
Interoperability
Equips agents with Work IQ, apps, and data, accelerating time to value and simplifying human-agent workflows across different platforms and ecosystems.
Furthermore, the Microsoft Agent Factory was announced to help organizations build and deploy agent fleets using Microsoft Foundry and Copilot Studio, all under a single metered plan.
Democratizing AI Security: Security Copilot Inclusion
A major Microsoft Ignite announcement aimed at enabling every customer to benefit from agentic defense is the inclusion of Security Copilot for all Microsoft 365 E5 customers.
Microsoft 365 E5 already provides foundational security capabilities covering threat protection (Microsoft Defender), identity management (Microsoft Entra), endpoint management (Microsoft Intune), and data security (Microsoft Purview). Security Copilot amplifies these existing capabilities with built-in agents.
Inclusion Details
Eligible Microsoft 365 E5 customers receive 400 Security Compute Units (SCUs) per month for every 1,000 user licenses, up to 10,000 SCUs monthly, starting with existing Security Copilot customers immediately and rolling out to all others in the coming months.
Agent Expansion: Beyond making the core platform accessible, Microsoft is dramatically expanding the ecosystem by introducing more than 40 new Microsoft and partner-built agents, adding to the 37 Security Copilot agents already available. This includes 12 new Microsoft-built agents across the core security suite (Defender, Entra, Intune, and Purview).
These agents deliver transformative outcomes by providing specialized assistance:
Security Operations teams
Gain agents to triage alerts and enable natural-language threat hunting. The Phishing Triage Agent in Microsoft Defender has already helped SOC analysts detect malicious emails up to 550% faster in simulated scenarios.
Identity and Access admins
Can deploy new agents in Microsoft Entra that proactively remediate risky users and optimize Conditional Access policies, leading to up to 204% greater accuracy in identifying missing Zero Trust policies.
Data security professionals
Use agents in Microsoft Purview to discover, analyze, and remediate sensitive data risks.
IT admins
Use agents in Microsoft Intune to simplify complex tasks, turning requirements into policies and identifying devices for removal.
Productivity Amplified: Work IQ and Specialized Agents
Work IQ
The next layer of the agentic era is defined by the intelligence that drives agents within productivity workflows. This intelligence layer is called Work IQ.
Work IQ helps Copilot understand the user, their job, and their company through three components:
Data:
Rich knowledge from emails, files, meetings, and chats.
Memory:
Personal style, preferences, habits, and work patterns are unique to the user.
Inference:
Combining data and memory to predict the next best action and suggest the correct agent for a task.
Work IQ for custom agents allows organizations to securely build agents tuned for unique workflows, ensuring secure grounding that respects existing permissions and compliance controls.
Core Copilot and App Updates
- Agent Mode is becoming ubiquitous in Office apps: Word is now generally available; Excel is in preview and allows users to choose between OpenAI and Anthropic models for reasoning; and PowerPoint is available via the Frontier program.
- The Windows entry point for agents, Copilot, and search is Ask Copilot on the taskbar, accessible instantly by voice or text.
New Specialized Workflow Agents
Microsoft also introduced powerful new agents designed as AI teammates to transform business processes:
- The Facilitator Agent in Teams drives the agenda, takes notes, keeps meetings on track, and manages actions.
- The Sales Development Agent works autonomously to build a pipeline, nurture leads, and personalize outreach, connecting directly to CRM tools like Salesforce and Dynamics 365.
- The Workforce Insights Agent gives leaders comprehensive, real-time insights across roles and tenure to support data-driven workforce decisions.
Autonomous Defense: Predictive Protection
To defend at the speed of AI, security must become predictive. A key Microsoft Ignite announcement in this area is Predictive Shielding with Microsoft Defender.
This new capability goes beyond automated disruption by analyzing graph insights and threat intelligence gathered from the 100 trillion signals Microsoft processes daily. Predictive Shielding anticipates cyber attacker movement, forecasting likely attacker pivots, and then proactively applies targeted hardening actions to block exploitation of adjacent resources.
Other autonomous defense enhancements include:
Microsoft Purview Expansion
Enhanced data security and compliance controls for Microsoft 365 Copilot now include comprehensive data oversharing reports, automated bulk remediation of overshared links, and Data Loss Prevention (DLP) for Copilot and chat prompts.
Security Dashboard for AI
This tool centralizes discovery, protection, and governance for AI agents, apps, and platforms by aggregating security signals from Defender, Entra, and Purview, giving CISOs unified visibility.
Defender Experts Suite
A future offering (early 2026) that combines human-led, AI-powered managed Extended Detection and Response (XDR) with proactive incident response services.
Conclusion
Microsoft’s Day 1 announcements at Ignite 2025 make one thing clear: the future of work will be secured and powered by AI agents operating at scale. With Agent 365, expanded Security Copilot access, Work IQ, and autonomous defense capabilities, Microsoft is laying the foundation for organizations to enter the Agentic Era confidently. These innovations give every business the tools to govern agents, strengthen security, and enhance productivity, setting the stage for the next generation of human-led, agent-operated workplaces.
