Identity attacks no longer hinge on who a cyberattacker compromises, but on what that identity can access. As organizations manage growing numbers of human, non-human, and agentic identities, their access fabric multiplies across apps, resources, and environments, which increases both operational complexity for identity teams and risk exposure for security teams.

The challenge isn’t just scale, it’s fragmentation. From our latest Secure Access report, research shows that 32% of organizations say their access management solutions are duplicative, and 40% say they have too many different vendors. That fragmentation for security vendors makes it harder to maintain consistent access controls and correlate risk across identities. When risk is distributed across dozens of disconnected accounts and permissions, visibility fragments and blind spots emerge—creating ideal conditions for cyberattackers to move laterally without detection. Securing identity in this reality requires more than incremental improvements. It calls for a shift from fragmented controls to an integrated, end-to-end approach that treats identity as a shared control plane that is informed by a continuous, foundational security signal.

Why fragmentation fails—and what must replace it

With the traditional model of identity security—built on siloed directories, disconnected access policies, and bolt-on threat detection—cyberattackers don’t have to break defenses, they just move between them. Permissions go uncorrelated, access policies drift as environments evolve, and lateral movement hides in the gaps.

For defenders, this creates a dangerous imbalance. Identity signals flood the security operations center (SOC) without the context to act, while identity teams enforce access without visibility into active cyberthreats. Risk accumulates across systems, but responsibility—and insight—remains fragmented.

Fixing this doesn’t require more alerts or point solutions. It requires an integrated fabric that brings together all of the identities, access, and signals.

A modern identity security solution must unify three critical layers:

• The identity infrastructure: The systems and services that underpin every access decision. This includes the identity provider, authentication services, single sign-on (SSO), user and group management, and the systems that establish and maintain trust across the enterprise. Without this foundation, there is no authoritative source of truth for who an identity is, what it can access, or how it should be governed. It’s the layer many security vendors lack—and the one Microsoft delivers at global scale.
• The identity control plane: Where privileged identity management and access decisions are enforced in real time, based on dynamic risk signals, behavioral context, and policy intent. This is where identity and security converge to adapt access as conditions change, powering real-time response to identity threats.
• End-to-end identity threat protection: Before a cyberattack, it proactively reduces posture risk by eliminating excessive access and closing identity exposure gaps. When threats emerge, it detects identity misuse in real time, surfaces lateral movement, and drives rapid containment—connecting integrated signals and response across the full attack lifecycle.

When these layers operate in isolation, risk is missed. When they operate as one, identity becomes a powerful security signal—enabling earlier detection, smarter decisions, and faster response.

Redefining identity security for real-time defense

Microsoft is delivering a new standard for identity security solution—one that unifies identity infrastructure, access control, and threat response into a single, real-time platform built for speed, precision, and autonomy.

We start with the identity infrastructure: the foundational identity layer powered by Microsoft Entra. As one of the most widely adopted identity platforms in the world with billions of authentications managed daily, it provides resilient SSO, user and group management, and trust establishment at global scale—a layer many security vendors simply don’t have access to.

We collapse identity sprawl, correlating related accounts across cloud and on-premises into a single identity view, so risk assessment is no longer scattered across disconnected systems. This gives security teams a real‑time understanding of what an identity and its correlated accounts can access, not just who it is—allowing them to spot dangerous access paths early, limit impact, and disrupt lateral movement before attackers turn access into impact. Likewise, it gives identity teams visibility into whether a user flagged as a high risk was just a one-off or if its associated with other accounts, informing what access decisions to make.

On top of that foundation is a real-time identity control plane designed for how attacks actually unfold. Microsoft Entra Conditional Access continuously evaluates risk as access is used, not just when it’s granted—tracking signals from identity, device, network, and broader threat intelligence throughout the session. As conditions change, access adapts in real time, helping identity teams limit exposure and prevent risky access while giving security teams the ability to interrupt attack paths while activity is still in motion. This is adaptive access driven by connected intelligence—not static policy.

And when risk turns into a threat, we act—automatically and inline, which results in a faster response. Microsoft’s threat protection is differentiated by automatic attack disruption: a capability that intervenes mid-attack to isolate compromised assets by terminating user sessions, revoking access, and applying just-in-time hardening to stop lateral movement and privilege escalation. It’s not just detection—it’s defense in motion.

To accelerate response, we’ve extended Microsoft Security Copilot’s triage agent to identity. It uses AI to filter noise, surface high-confidence alerts, and guide analysts with clear, explainable insights—reducing time to action and analyst fatigue.

This end-to-end approach shifts identity from an expanding source of exposure into a strategic advantage. Instead of reacting after access has already been abused, it helps ensure that risk is evaluated continuously, access decisions are made in real-time, and organizations can defend more effectively as attack paths emerge to stop identity‑based attacks before they escalate into business impact.

Innovation that moves the industry forward

At RSAC 2026, we announced a set of innovations in identity security that are designed to help organizations move from fragmented awareness to confident, identity-centric protection:

• The new identity security dashboard in Microsoft Defender doesn’t just summarize alerts, it reveals where identity risk actually concentrates across human and nonhuman identities, account types, and providers. Instead of hopping between consoles, teams can immediately see which access paths matter most, where blast radius is largest, and where action will have the greatest impact.
• A new unified identity risk score correlates together more than 100 trillion signals across Microsoft Security including identity behavior, access risk, and threat signals into a single, actionable view of risk. This allows teams to move directly from understanding exposure to enforcing protection—applying controls at the point of access, natively through risk-based Conditional Access policies.
• Adaptive risk remediation helps identity and security teams contain modern cyberattacks more efficiently while maintaining strong protection. When risk is detected, users easily regain access and Microsoft Entra ID Protection adapts risk remediation based on the type of cyberthreat and the credentials used. This reduces reliance on help desk processes and lowers manual response effort.
• Automatic attack disruption fundamentally changes the outcome of identity-based attacks. Instead of detecting suspicious behavior and waiting for the security teams to respond, it intervenes while cyberattacks are in progress—terminating sessions, revoking access, and applying just-in-time hardening to shut down cyberattacker movement before lateral spread or privilege escalation can occur.
• Security Copilot’s triage agent now extends to identity. Using AI to collapse signal overload into clear, recommended action, the agent surfaces high confidence threats, explaining why they matter, and guides analysts to the right response while attacks are still unfolding. The result is faster containment with far less analyst fatigue.
• Expanded coverage across the modern identity fabric, including deeper visibility into non-human identities and new integrations with third-party platforms like SailPoint and CyberArk—providing protection that spans the full ecosystem, not just first-party assets.
• A new coverage and maturity view helps organizations assess their current identity security posture, identify gaps, and prioritize next steps—transforming identity protection from a static checklist into a dynamic, guided journey.

These innovations are deeply integrated, continuously reinforced, and designed to work together—enabling security and identity teams to operate from a shared source of truth, with shared context, and shared urgency. Read more about redefining identity security for the modern enterprise.

They are designed to help organizations shift from reactive identity management to proactive identity defense—and from fragmented tools to a unified platform built for real-time security across human, non-human, and agentic identities.
