Continuous identity security: secure every account and session
Why securing enterprise identity is harder today
Enterprise identity has changed a lot over the last few years.
Users are no longer sitting behind a single network perimeter, accessing a small set of applications from managed devices. Today, they work from anywhere. Applications sit across SaaS, private data centers, cloud platforms, and partner environments. Devices can be managed, unmanaged, personal, mobile, or sometimes simply unknown.
And then there are the identities.
Human and non-human identities (NHIs), such as service accounts, SaaS accounts, cloud identities, legacy accounts, and now even AI-driven workflows are adding to the mix. Identity sprawl has become one of the biggest challenges security teams are trying to solve.
Attackers have noticed this shift too. They are not always trying to force their way in through exposed infrastructure. Increasingly, they are logging in with valid credentials, abusing excessive privileges, hijacking sessions, and blending into everyday user activity.
That means identity can no longer be treated as a one-time login check.
We need to know which accounts exist, how they are being used, what sessions are active, and whether the level of trust should change as risk changes.
In simple terms, we need to secure every account and every session. Three identity security challenges teams face
When we talk to customers about identity security, three (3) challenges usually come up.
Fragmented identity visibility: Most organizations have more than one identity source. There may be Microsoft Entra ID, Active Directory, SaaS directories, cloud accounts, privileged accounts, service accounts, and third-party identities. Each system has its own view of users, permissions, activity, and risk. The security team is often left trying to piece it all together manually and understand overall identity posture along with this.
Inconsistent access enforcement: Organizations usually have security controls in place, but they do not always work as one system. MFA may sit in one place. Device posture may be checked somewhere else. SaaS access, private app access, and network access may all follow separate policy models. That makes it hard to apply zero trust consistently across users, devices, applications, and environments.
Static decisions in a dynamic world: A user may pass MFA in the morning and get access. But what happens if the account starts behaving unusually later in the day? What if the device posture or device location changes? What if the session becomes risky? What if an account has more privileges than it should?
Identity risk is not static. So, security cannot afford to be static either.
This is where zero trust needs to evolve from a one-time authentication decision into a continuous, per-session context-aware model.
Identity becomes the new control plane.
The solution: how Cisco enables continuous identity security
Cisco brings a platform approach to identity security by connecting identity visibility, access enforcement, network control, and threat response through Cisco Security Cloud.
At the center of this approach is Cisco Identity Intelligence, which helps organizations understand identity activity, discover risky accounts, identify excessive privileges, and close the gap between authentication and access.
But visibility on its own is only half the job. The real value comes when identity intelligence can drive action.
Cisco Duo helps verify trusted users and trusted devices with strong MFA, device trust, posture checks, and risk-based access.
Cisco Secure Access extends identity-aware enforcement across SaaS, internet, and private applications, helping users reach the applications they need without giving them broad access to everything behind the network.
Cisco ISE brings identity deeper into the network, supporting identity-based access for campus, branch, wireless, wired, VPN, and segmentation use cases.
Splunk helps bring identity signals together with broader security telemetry, giving teams better context to detect, investigate, and respond faster across the environment.
Together, these capabilities help organizations move away from static access decisions and toward continuous identity security.
Not just: did the user log in?
But: is this account trusted, is this device healthy, is this session behaving normally, and should this access continue?
Continuous identity security example: finance user login
Let’s make this real.
Imagine a finance user accessing a sensitive application.
In a traditional model, the decision may be fairly simple. The user belongs to the Finance group. MFA is complete. Access is allowed.
That is useful, but it does not tell the whole story.
With Cisco, the decision can include much richer context.
Duo verifies the user and checks whether the device is trusted and healthy.
Cisco Identity Intelligence looks at the account itself. Is this identity behaving normally? Does it have excessive privileges? Has it shown unusual access patterns? Is there a signal that should change the access decision?
Cisco Secure Access applies the right policy at the application level. If the user, device, and session look trusted, the experience stays simple. If something looks risky, access can be challenged, limited, or blocked.
Splunk can correlate that identity activity with other security signals from across the environment. This helps the security team understand whether the event is isolated or part of a larger attack path.
That is the balance customers are looking for: tighter control when risk is high, and a smoother experience when trust is strong.
Why a connected identity platform beats point solutions
Cisco’s approach is different because identity is not treated as a standalone control.
Identity connects to access.
Identity connects to the network.
Identity connects to threat response.
And identity connects to the broader security operations workflow through Splunk.
Every account needs visibility. Every session needs context. Every access decision needs risk awareness. And every control point needs to work together.
This matters even more as organization adopt more SaaS, more cloud, more remote access, more third-party users, and more AI-driven workflows. The number of identities will keep growing. The number of sessions will keep increasing. And attackers will keep looking for the weakest identity path within the ever-growing attack surface.
The answer is not to add yet another disconnected identity tool and create more work for already stretched security teams. The answer is a connected security platform that can see identity risk early, enforce the right access policies, extend control into the network, and help teams respond to incidents faster.
Organizations should assess where identity visibility gaps, inconsistent access policies, and unmanaged risks exist across their environment, and explore how Cisco and its partners can help build a connected zero trust architecture that protects every account and every session.
