Cisco Identity Service Engine (Cisco ISE)


Network devices are the primary means for wired networks, wireless and VPN connections for users and the terminal to connect to the network to access various services. Using credentials such as passwords, certificates, tokens or at least the MAC address of the endpoints. Now these credentials reach ISE in a process called authentication

Cisco ISE offers distinct configurable personas, services, and roles, which allow you to create and apply Cisco ISE services where they are needed in the network. The result is a complete Cisco ISE deployment that operates as a fully functional, integrated system. Additionally, Cisco ISE nodes can be deployed with one or more of the administration (PAN), monitoring (MnT), and policy service (PSN) characters.

User authentication policies in Cisco ISE allow you to provide authentication for a number of user login session types using various standard authentication protocols, including but not limited to PAP, CHAP, PEAP and EAP password authentication. Cisco ISE specifies the allowed protocol(s) that are available to the network devices against which the user is trying to authenticate and specifies the identity sources from which user authentication is validated. The following features are available in recent versions of ISE:

Cisco ISE Agentless POS

Cisco ISE now supports agentless posture, giving you the ability to identify, classify, and configure an endpoint or device without installing anything on it. This gives your team the flexibility to manage the speed and ease of onboarding new users and devices anytime, anywhere as they see fit.

ISE can also be configured to automatically identify and classify new devices based on their behavior using AI endpoint analysis. This way the policy can be applied dynamically when the device’s position or situation changes and you don’t have to manually reconfigure it.

Cisco ISE on Azure

You can now transfer ISE to the cloud as it is already deployable on VMware and AWS. ISE also supports SSO with Microsoft Azure Active Directory so you can use cloud-based identity to authenticate users. Cisco is leading the migration to the cloud. As your business moves there, ISE is there with you to support and enable your cloud-first strategy.

Finally, to help you manage everything with ease, Cisco has completely redesigned the user experience with ISE to make it more intuitive., Support monitor and easy to set up and use

New Cisco ISE UI

The ISE menu system has been restructured into expandable categories accessible from the Hamburger menu. Everything is logically organized to quickly get you where you need it via expandable drop-down menus.

Cisco Identity Service Engine License

Basically the Cisco ISE license activation has been changed in recent years. So far the Cisco license The structure used in ISE version 2.x was called the Lego model. In this model, there are three different license levels: ISE-based Licence for user and application visibility, ISE Plus license for context and ISE Apex License For compliance. Thus, it is called the Lego model because you can assemble your licenses as and when you need their associated features. The features you can use with one license do not overlap with the features you can use with another license and you must have a base license to use the Plus and/or Apex license.
