Take control of your network with identity at the core
Cisco ISE gives you the visibility, context, and enforcement to make precise, real-time decisions—so you can continuously verify trust and control every connection across your hybrid environment.
Networks are more dynamic than ever, with users, devices, and IoT endpoints connecting across wired, wireless, VPN, and cloud environments. Yet visibility remains fragmented, identity context is incomplete, and enforcement is often inconsistent. Most solutions focus only on granting access—leaving a critical gap in controlling what happens after connection.
Cisco Identity Services Engine (ISE) bridges this gap by unifying visibility, identity, and enforcement into a single platform. It discovers and profiles every user and device—including unmanaged and IoT devices—without requiring agents, then enriches that data with identity context from across your ecosystem.
With this foundation, Cisco ISE continuously verifies trust and enforces least-privilege access—not just at the point of entry, but throughout the entire session. It extends control beyond access using identity-based segmentation, ensuring users and devices only communicate as intended. The result: stronger security, reduced risk, and a complete Zero Trust posture across your hybrid network.

Fragmentation Across Identity, Visibility, and Enforcement Is Slowing Security Outcomes
Rising Complexity Slows Zero Trust Maturity
As organizations adopt Zero Trust frameworks such as NIST and CISA models, many remain stuck in early stages of maturity. Initial efforts often prioritize identity and access, but advancing to continuous verification and adaptive, policy-based control across the entire environment is far more difficult.
A primary obstacle is fragmented identity. Identity data is distributed across directories, MDMs, CMDBs, and security tools—with little real-time exchange of context. This creates inconsistent and incomplete identity context, limiting the ability to make accurate, risk-aware decisions. Without a unified identity foundation that can drive enforcement, Zero Trust cannot evolve beyond basic access control.
SSE and SASE Improve Access— But Not Full Network Control
SSE and SASE architectures including ZTNA solutions have become central to securing application access, especially for remote and hybrid users. However, they primarily focus on north-south traffic and application-layer control. They provide limited visibility into unmanaged and IoT devices and lack the ability to govern how users and devices interact within the network (east-west traffic).
Traditional NAC solutions were designed for static, location-based environments. They rely on IP addresses and VLANs to enforce access at the point of connection but lack the flexibility to adapt to dynamic, hybrid environments or to enforce policy consistently beyond initial access.
As a result, organizations often deploy multiple disjointed solutions— each solving part of the problem but none providing unified, continuous control. Visibility, identity, and enforcement remain fragmented across these solutions and operate independently. Without a common control plane, context is lost between systems.
The Missing Link: Identity-Driven Enforcement
When identity, visibility, and enforcement are not unified, policy becomes inconsistent and reactive. Enforcement points lack full context, policies don’t follow users and devices, and response actions are delayed or manual.
To reach higher levels of Zero Trust maturity, organizations must move beyond isolated capabilities and make identity the foundation for continuous, network-wide control. Without this, the gap between access and control persists—leaving networks exposed to lateral movement, operational complexity, and increased risk.
Recent industry research shows that while organizations are investing heavily in identity and segmentation, most still operate with fragmented tools—limiting their ability to turn insight into real-time enforcement.
Identity sprawl creates operational complexity. IT and security teams use an average of 5 tools to resolve a single identity issue—highlighting how identity, visibility, and enforcement remain fragmented across systems.
Limited visibility leads to identity risk. 75% of organizations lack full visibility into identity vulnerabilities, and 94% say identity complexity reduces overall security, making it harder to make accurate, risk-based access decisions.
Segmentation is a priority—but hard to scale. 79% of organizations identify segmentation as critical, yet only 33% have fully implemented segmentation across their environments, citing complexity and lack of visibility as key barriers.
Disconnected tools delay response. Only 52% of organizations have fully integrated identity and device telemetry, leaving nearly half without the unified context needed for accurate, real-time policy enforcement.
Identity Gaps Are Driving Financial Losses. More than 50% of organizations have experienced financial losses from identity-related breaches, demonstrating that gaps between detection and enforcement have real business consequences.
The takeaway: Organizations are not lacking tools—they are lacking integration. When identity and segmentation operate in silos, policies are inconsistently enforced, threats spread more easily, and response is delayed. Unifying identity, visibility, and enforcement into a single control plane is essential to reduce risk, limit lateral movement, and achieve Zero Trust at scale.

Unify visibility, identity, and enforcement into a single control plane.
Cisco Identity Services Engine (ISE) unifies visibility, identity, and enforcement into a single, network-wide control plane. By connecting context to action, it ensures policy is applied consistently—before, during, and after access—across your entire hybrid environment.
True visibility without agents
ISE discovers and profiles every user, device, and IoT endpoint—including unmanaged assets—using AI-driven analytics and behavioral profiling. This agentless approach eliminates blind spots and accelerates time to value without requiring endpoint software.
One identity-driven control plane, across your network
Cisco ISE builds a unified identity context by integrating with directories, MDMs, and asset systems. Policies enforced across campus, branch, data center, and cloud, based on identity and device posture—not just location—eliminating gaps between environments.
Consistent enforcement and continuous verification
Whether access is established through wired, wireless, cellular, VPN, or ZTNA, Cisco ISE acts as a centralized policy engine—ensuring consistent enforcement across on-premises and cloud environments while continuously verifying trust throughout the session, not just at the point of authentication.
Identity-based segmentation at scale
Using Security Group Tags (SGT), ISE controls how users and devices communicate across campus, branch, data center, and cloud. Policy follows the identity everywhere removing the need for complex network redesigns and significantly reducing lateral movement.
Automated threat containment
ISE shares identity and device context with 70+ Cisco and third-party security solutions through pxGrid integration. This enables automated, network-based response—allowing faster threat isolation and preventing further spread.
Flexible Deployment with Faster Time to Value
Cisco ISE supports deployment across on-premises and cloud environments, giving you the flexibility to align with your architecture and operational model. Its agentless approach simplifies onboarding, reduces operational overhead, and accelerates time to value.
With Cisco ISE, you move beyond fragmented access control to a unified approach that reduces risk, limits lateral movement, and simplifies operations—while delivering consistent, scalable security across your entire network to enable Zero Trust outcomes.
