We are a system integrator and Cisco ISE is one of the products that we sell and implement at our customers side. I have built ISE's POC and provided training to our customers.
I also used real rent lab which was including; Active Directory integration, network access and core switches, access points, wireless access controller, and end points. (some end points have cisco client - anyconnect, and have not), and Web Server for creating wireless authentication portal solution end to end
The AAA features were awesome and have important attributes, and also the security groups (SGTs) concept to enforce policies for each group of users, regardless they coming via wired or wireless network devices. also i see the guest authentication is very rich and easy tom implement
Cisco ISE offer one central point to create different policies for different group of users and enforce policies to each entity regardless it connected to network through wired or wireless network devices. it provide in this way more mobility and wireless-wired converged network. Also it integrates very well with network devices to control ports configurations services authentication and authorization. ISE also integrate with DNA center and stealthwatch to enable customer have SDN (Software defined Network) Fabric.
Combines authentication,authorization,accounting(AAA),posture,and profilerinto one appliance
Provides for comprehensive guest access management for Cisco ISE administrators.
Enforces endpoint compliance by providing comprehensive client provisioning measures and assessing the device posture for all endpoints that access the network,including 802.1X Environments
EmploysadvancedenforcementcapabilitiesincludingTrustsecthroughthe use of SecurityGroup Tags(SGTs) and Security Group Access Control Lists (SGACLs)• Supports scalability to support a number of deployment scenarios from small office to large enterprise environments
The ISE software needs to be improved in role to be easier to administer. SOftware enhancement required to have easier way to find the featured required to implement and also need enhancement of features sorting. Completing processes can be complex when try to implement some solutions. also steps are complex and the troubleshooting as well. As an example, if you intend to make AAA policy and enforce it on a group of users, you will find the software very confusing................................
I have been using Cisco ISE for three months.
We did not use another similar solution prior to this one.
The initial setup was fine.
The price for Cisco ISE is high.
We did not evaluate other options before adopting this solution.
We may have borrowed ideas from other sources, but I do not think so. More based on years of experience with ACLs, firewall rule sets and working on the ISE flow and best practices. Also creating a flow chart of ISE flow is great. If you can create it prior to configuration it will guide you. And then create or adjust after implementation. Remember that if your flow chart is clumsy or difficult to organize chances are that your logic is also clumsy or even incorrect. With that said if you are new to ISE (and Dot1x, EAP and RADIUS) a poor flow chart may not reflect an incorrect implementation but a lack of understanding of the underlying principles. GOOD LUCK again!
