The Cisco Identity Services Engine (ISE) offers a network-based approach for adaptable, trusted access everywhere, based on context. It gives the user intelligent, integrated protection through intent-based policy and compliance solutions.
Well suited... I've used it for both wired and wireless access, and it's perfect for that. In addition to enforcing security on the port, you can also lock down east-west traffic. When you get to the point where you're configuring secure group tags and things like that, you can keep people from getting to places they shouldn't. Basically, you could turn your entire network into a firewall if you wanted to. You can secure access based on the identity of any given user through role-based authentication. For example, if you have salespeople and you don't want them accessing your financial or PCI environment, they authenticate as a salesperson and you can completely stop them from getting to any of that. That's really important, especially for us. Our payment card infrastructure servers are heavily locked down. Granted, in our situation, we firewall all that off anyway, but you still don't want some random individual to be able to even attempt that sort of thing. That's what it's really good for. I'm trying to think of a weakness. I don't know. We don't really struggle with it. There's nothing that I use it for where I wish it were better, at least not that I can think of offhand. I'm sure there are things, I just can't think of anything off the top of my head.
For us the solution is very easily useable on its own. Perhaps that has to do because we started using ISE in the 1.2 days and have seen it grow during the years. Policy creation, etc. is all very visible and thus easy to use. Deployment of multiple nodes is also incredibly easy and flexible. You can easily add or remove nodes as you wish.
We do have to occasionally reboot the servers when they get low on memory, but we're also a few versions behind. Availability has generally been pretty good though with no major outages in the time that we've had it implemented.
Cisco support is second to none, both in terms of how you access support but also the knowledge of the individual support teams. If you focus on one technology and provide "manufacturer support" then you can rest assured that you are accessing Cisco's top individuals. I feel like this is a USP for Cisco support.
I think our system integrators lacks some competencies and this has led to an implementation that is still perfectible. (i.e. dedicating an interface for intra-cluster communication)
I think all give some visibility of device monitoring and management, but Cisco Identity Services Engine gives a good way to manage more details about the device in a centralized way that gives a wider range of monitoring and control than the other softwares individually. I don't think Cisco Identity Services Engine eliminates the need for these other software as of now, but there is potential for Cisco Identity Services Engine to be able to take over more of these roles.
It's fully customised and comprehensive. only thing is you need to know what you want. Proper research and planning would save lots of time and effort .
I don't know about negatives because we haven't seen it right now, but positive impact is one is the roadmap we have. And now since we are going ahead with doing the deployment of Cisco ISE, we see that we are getting closure to, so at the end of the day, we have to make sure that operationally we stay excellent. So that's where operational excellence comes in. Cisco ISE is basically addressing that for us. Right now we are in a situation if there is a WIFI issue or if there is an authentication issue, it gets really difficult to isolate the problem. But with Cisco ISE , this functionality is going to come in. So we believe that it would be a good ROI.
