IT Business Manager at Telefónica
Simple, works well, and has a lot of features
Pros and Cons
- "It's scalable."
- "We are very happy with the solution and we have no problem using Cisco ISE solutions."
- "The price here in Brazil is very expensive."
- "Sometimes we face some infrastructure where there are multiple vendors and sometimes the ISE is not the best tool to manage multiple vendor infrastructure."
What is our primary use case?
This solution provides access to the employees of the company.
What is most valuable?
It works. It is simple. It works very well. We have a good strategic setup. We are very happy with the solution and we have no problem using Cisco ISE solutions.
The solution is stable.
It's scalable.
What needs improvement?
I'm not working in the IT team. I'm working the sales team. While there are a lot of features that we could improve in our organization, I can't speak to the exact changes that should be made.
We'd like to be able to integrate the product with our solutions. Sometimes we face some infrastructure where there are multiple vendors and sometimes the ISE is not the best tool to manage multiple vendor infrastructure.
The price here in Brazil is very expensive.
Configurations can be a bit complicated.
Sometimes we have problems integrating logs into SIEM solutions. We have to deliver some logs to a SIEM secret platform, and sometimes it does not work well. It would be better if we had better integration or a better way to deliver the logging SIEM platforms.
For how long have I used the solution?
I've been using the solution for five to six years.
What do I think about the stability of the solution?
The stability is good. There are no bugs or glitches. It doesn't crash or freeze.

We have 6,000 people in Brazil using the solution.
How are customer service and support?
I consider technical support to be perfect. Anytime that I have problems with shifting solutions, they work well with me and I have no problems with working with them.
Which solution did I use previously and why did I switch?
I'm a reseller from Fortinet and Cisco solutions. I also have experience with Check Point.
How was the initial setup?
I can't speak to how the setup goes. I'm not working directly in deployment. What I've heard from my customers, for example, is that it is not difficult to set up, however, it may be to run all the features.
What I've heard is the first setup is very, very easy and to do some adjustments is very easy, however, when you want to go further in the configuration, that could be a bit easier.
What's my experience with pricing, setup cost, and licensing?
I can't speak to the exact pricing of the product.
What other advice do I have?
I work with various versions of the solution.
We're resellers.
Others should know it's a very good solution, very stable. There are a lot of features, and it is a secure solution. It's the first solution that we indicate to our customers and most of the time, the decision of the customer is to deploy a Cisco product.
I'd rate the solution nine out of ten.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Cisco Identity Services Engine (ISE)
July 2026
Learn what your peers think about Cisco Identity Services Engine (ISE). Get advice and tips from experienced pros sharing their opinions. Updated: July 2026.
906,960 professionals have used our research since 2012.
Network Engineer at a manufacturing company with 201-500 employees
Allows us to create different vendor and employee access groups
Pros and Cons
- "The policy sets give us more granular groups for end-user access."
- "It has also given us a lot of extra security as the backbone of authentication for our VPN and wireless network."
What is our primary use case?
It's mostly for authentication to our network for our end-users.
How has it helped my organization?
It's allowed us to create groups for different vendors and for employees in various groups in our company, without giving everyone access.
It has also given us a lot of extra security as the backbone of authentication for our VPN and wireless network.
What is most valuable?
The policy sets give us more granular groups for end-user access.
For how long have I used the solution?
I've been using Cisco ISE (Identity Services Engine) for five years.
What do I think about the stability of the solution?
The stability is really great. We haven't had any issues with it. We've had it for a long time. We ran an old version for three or four years without any issues.
What do I think about the scalability of the solution?
From what I have read, the scalability seems good. We haven't had to deal much with that. We have two nodes and about 2,000 sessions going at once.
How are customer service and support?
Technical support is very good. They've always been there to answer any questions, and if they don't know the answer they make sure to find someone who can give me the answer.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
Cyber security resilience has been at the top of our list since 2020 because we had so many people working from home and that increased as time went on. That opened our eyes.
How was the initial setup?
I was involved when we upgraded at the beginning of this year. It was pretty straightforward, although we reached out for outsourced help.
What about the implementation team?
We used a CDW consultant.
What was our ROI?
For us, the return on investment is that it gives us easy ways to divide up our end-users for authentication, especially for our VPN.
What's my experience with pricing, setup cost, and licensing?
The pricing seems fair. The licensing can be confusing, but it is still pretty good.
Which other solutions did I evaluate?
I was asked a couple of years ago, when we were having issues with ISE, if there were alternatives, and I said I didn't want to switch because we're so embedded in this solution already.
What other advice do I have?
Talk to someone outside of Cisco too, if you're thinking about ISE. That way, you can get all the information.
We wanted to outsource some of our work because I only have two years of admin experience and another of our network engineers has about a year. This way, if the system goes down, we have a quick way to get it back up.
I would tell leaders who want to add cyber security resiliency to make sure they include team members who are involved and not just make decisions on their own.
Which deployment model are you using for this solution?
On-premises
Disclosure: My company does not have a business relationship with this vendor other than being a customer.
Technical Leader at Línea Directa S.A.S / Aplicación e Ingreso
We are very secure now because only corporate endpoints can be authenticated on our wireless
Pros and Cons
- "Authentication is the most valuable feature because it puts our company at another level of security."
- "We are a very secure enterprise now because only our corporate endpoints can be authenticated on our wireless."
- "It's expensive to scale Cisco ISE, but our situation is stable so we don't need to scale it for now."
What is our primary use case?
We use it for MAC Authentication Bypass, 802.1X authentication, and certification and validation against Active Directory. Because MAC devices can't be enrolled in the domain, we were doing a manual installation of certificates.
How has it helped my organization?
We are a very secure enterprise now because only our corporate endpoints can be authenticated on our wireless. Before, any device could be connected to our production network. And the corporate endpoints have antivirus and anti-malware. Things are more and more secure.
What is most valuable?
Authentication is the most valuable feature because it puts our company at another level of security. It establishes trust for every access because we use only corporate endpoints. If somebody has another device, they can't connect it to the enterprise network because we haven't implemented bring-your-own-device yet. We have five warehouse buildings and all our operations are around logistics and that means external people don't come to our buildings.
For how long have I used the solution?
I have been using Cisco ISE (Identity Services Engine) for three years.
What do I think about the stability of the solution?
It's very stable.
What do I think about the scalability of the solution?
It's expensive to scale Cisco ISE, but our situation is stable so we don't need to scale it for now. In the future, we will need a more scalable solution.
It is used for all our departments, all end-users, all corporate endpoints. And when we use MAC Authentication Bypass, we include printers and VIP cell phones.
How are customer service and support?
Tech support is very good.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We didn't have a previous solution.
How was the initial setup?
The deployment was a little complex, but not because of the solution. It was more an issue for our people because it was a mindset change.
It took us about six months to deploy. Because we didn't have a previous solution, we just deployed it one department at a time across our four departments.
What about the implementation team?
We used an integrator, ITS Infocom. Experience-wise, it was very good. On our side, we had three people involved.
What was our ROI?
Since implementing Cisco ISE, we haven't had any attacks against our application.
What's my experience with pricing, setup cost, and licensing?
Pricing is not a problem for Cisco because it has a lot of features and not much competition, although it's more expensive than other products. But if I do a cost-benefit analysis, Cisco provides high quality.
Which other solutions did I evaluate?
We looked at Aruba. Cisco ISE is much better.
What other advice do I have?
Be patient with the implementation. It can be very difficult for the clients, the people using it, because it requires a change of mindset.
Which deployment model are you using for this solution?
On-premises

Network engineer at a financial services firm with 1,001-5,000 employees
Enables us to define our policies and authenticate users based on them, eliminating threats
Pros and Cons
- "It integrates with the rest of our platform, like our firewall, and helps us a lot. It also does a good job establishing trust for every access request."
- "The ROI we have seen is because Cisco gives us what they promised us; they deliver, our requirements are being met, and that results in getting value for what we pay."
- "With the recent release of the solution, we had a bunch of bugs and we had to delay our deployment. Other than that, the solution is good."
What is our primary use case?
We use it for network device administration and for user access.
How has it helped my organization?
It has really helped us when it comes to security. It has eliminated trust from our network architecture because, with the solution in place, you tell us who you are and, based on who you are, we give you access. The solution provides us with a platform to define our policies. Users get into our system based on those policies. That eliminates threats. If you are not who you say you are, it will block you completely from our network.
What is most valuable?
It integrates with the rest of our platform, like our firewall, and helps us a lot. It also does a good job establishing trust for every access request.
What needs improvement?
With the recent release of the solution, we had a bunch of bugs and we had to delay our deployment. Other than that, the solution is good.
For how long have I used the solution?
I have been using Cisco ISE (Identity Services Engine) for 10 years.
What do I think about the stability of the solution?
Cisco ISE has come a long way when it comes to stability. It's getting better.
What do I think about the scalability of the solution?
It's very scalable. We have it deployed in two data centers, and we're managing about 10,000 endpoints.
How are customer service and support?
TAC is very responsive whenever we call them.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
Currently we have two solutions that do the same kinds of things. For our wireless infrastructure, we use Aruba, but for our wired access, we use ISE.
What was our ROI?
The ROI we have seen is because Cisco gives us what they promised us. They deliver. Our requirements are being met and that results in getting value for what we pay.
What's my experience with pricing, setup cost, and licensing?
Since we have a complete Cisco portfolio, including an Enterprise Agreement, it's not simple for me to compare what we're paying with the prices of other platforms.
Which other solutions did I evaluate?
We evaluated other companies and what they each do differently and looked at what was the better fit for our requirements.
Cisco TAC is really good. Whenever we have issues, we know they are there and that they will help us out with troubleshooting. The support of the other companies we looked at is not that great.
When I compare it with Aruba ClearPass and other solutions out there, I prefer Cisco. Cisco is number-one for user access, managing devices, and for network devices.
We don't leverage Cisco ISE for application access. We have another solution for that.
What other advice do I have?
Get some hands-on familiarity with it first. Do a PoC and get people who really know the solution to help you out during phase one before you deploy it.
Which deployment model are you using for this solution?
On-premises

Allows you to automate the collection of information
Pros and Cons
- "I like the automation of the collection of information."
- "If you deploy it with the correct policies, it's a wonderful product."
- "One of the issues that we used to have was with profiling because we're working with a service provider that uses a lot of bring your own devices."
- "Setup wasn't easy, especially if you haven’t worked with it intensively."
What is our primary use case?
We're using version 3.1, which is very stable. There have been a lot of improvements.
What is most valuable?
I like the automation of the collection of information.
What needs improvement?
We have only been deploying this version for three months. We haven’t had any issues, but we'll see how it goes. One of the issues that we used to have was with profiling because we're working with a service provider that uses a lot of bring your own devices. We haven't had any issues since we started using version 3.1.
For how long have I used the solution?
I have been using this solution for over 12 years.
What do I think about the stability of the solution?
There are no stability issues with version 3.1.
What do I think about the scalability of the solution?
It's stable. We deployed with a client in petroleum with about 200 users worldwide, and it was stable.
How was the initial setup?
Setup wasn't easy, especially if you haven’t worked with it intensively. VM is a little bit easier. If you don't deploy ISE with correct policies, it will be difficult.
If you deploy it with the correct policies, it's a wonderful product. You don't need to attach anything like your firewalls or creating rules.
What's my experience with pricing, setup cost, and licensing?
ISE has always been expensive compared to other products in terms of what it does on a user level. I haven't had a client who didn't say that ISE wasn't expensive. I’ve had an issue where I was just selling four boxes, and it was four million. It was a high-end box, and the client didn't take it. They end up going with VM.
What other advice do I have?
I would rate this solution 9 out of 10.
It's one of the more difficult products to deploy.
You can learn a lot about ISE from their training videos. I would suggest watching the videos before deploying the solution. They have created good videos for ISE, from version 1.3.

Stable and easy to install network administration solution; provides network access control and fast support
Pros and Cons
- "Stable network administration solution that can be installed easily, and comes with fast technical support."
- "Cisco ISE (Identity Services Engine) is the best solution for Cisco network customers."
- "Compatibility with other vendors is what needs to be improved in Cisco ISE (Identity Services Engine). We should be able to use it with other vendors, for all specifications."
What is our primary use case?
Our customers use Cisco ISE (Identity Services Engine) as a network access control solution. Before they can get network access, you can do posture check, e.g. in the Windows version, or another version, then it is only after this posture check that the clients can enter the network.
What needs improvement?
Compatibility with other vendors is what needs to be improved in Cisco ISE (Identity Services Engine). We should be able to use it with other vendors, for all specifications. There should be integration with different vendors, e.g. Cisco ISE (Identity Services Engine) working with AccuPoint networks.
For how long have I used the solution?
I've worked in my current company in product pre-sales for one year, and prior, I worked for a different partner company in Turkey, so my total usage of Cisco ISE (Identity Services Engine) spans eight years.
What do I think about the stability of the solution?
Cisco ISE (Identity Services Engine) is a stable solution. It has good performance.
How are customer service and support?
If we need support from the vendor side, we can open a case, then the vendor replies to us as soon as possible. Support for Cisco ISE (Identity Services Engine) is fast.
How was the initial setup?
The installation of Cisco ISE (Identity Services Engine) was easy.
What's my experience with pricing, setup cost, and licensing?
Our customers pay for the license of Cisco ISE (Identity Services Engine). They have an annual subscription, rather than a monthly subscription.
Which other solutions did I evaluate?
I evaluated Fortinet.
What other advice do I have?
I'm a technical person, and I've worked for a company that does system integrations, including network pre-sales. My company sells Cisco ISE (Identity Services Engine) and Fortinet products in Turkey. I can also sell these products. My company is a gold partner of Cisco.
I've sold the on-premises version of Cisco ISE (Identity Services Engine).
Cisco ISE (Identity Services Engine) is the best solution for Cisco network customers. It is the best solution for Cisco network devices. As for network products from other vendors, we can use, or we could offer other network access control (NAC) solutions, e.g. Fortinet NAC, or Aruba Secure NAC, etc.
I'm part of the pre-sales team at our company. There are other people who are responsible for installing Cisco ISE (Identity Services Engine) post-sales, e.g. they install the solution for the customers. For this reason, I am unable to give information on how long it takes to install the solution.
We currently have over 30 users of Cisco ISE (Identity Services Engine).
I can recommend Cisco ISE (Identity Services Engine) to other users.
My rating for Cisco ISE (Identity Services Engine) is eight out of ten.

Stable security policy management that offers automation, visibility, and control; could be a little easier to implement
Pros and Cons
- "Cisco offers automation, visibility, and control as well as third party integration capabilities."
- "I would like for the next release to be easier to implement and to limit its dependencies around ISE, Windows, the network as a whole, etc."
- "This solution is a bit more complex to set up than in comparison to other options - it can take anywhere from two to five months depending on the use case."
What is our primary use case?
We are a partner with Cisco and am a part of an information security team that uses Cisco to provide security policy management via network, device and wireless access.
What is most valuable?
Cisco offers automation, visibility, and control as well as third party integration capabilities.
What needs improvement?
I would like for the next release to be easier to implement and to limit its dependencies around ISE, Windows, the network as a whole, etc.
For how long have I used the solution?
I have been using Cisco ISE for over six years.
What do I think about the stability of the solution?
This is a very stable solution with many integrations.
What do I think about the scalability of the solution?
Cisco's scalability depends on the design - small deployments are not scalable.
How are customer service and support?
Cisco support is good.
How was the initial setup?
This solution is a bit more complex to set up than in comparison to other options - it can take anywhere from two to five months depending on the use case.
What's my experience with pricing, setup cost, and licensing?
The price for Cisco ISE itself is very low, however, Cisco professional services are quite expensive. Subscription amount is dependent on number of users.
Which other solutions did I evaluate?
We looked at Forescout which is more user-friendly but they have a very vulnerable network.
What other advice do I have?
This is a good solution for security teams. If you do not have a security team, I would not recommend this product.
Overall, I would rate Cisco a seven out of ten.
Which deployment model are you using for this solution?
On-premises

Allows you to control or restrict access on your network and has a scalable licensing structure
Pros and Cons
- "The best features are the scalability and the license structure."
- "If someone is looking for a concrete solution to control the access, then ISE is a better solution."
- "The licensing documentation needs to be better."
What is our primary use case?
The solution is used for controlled access in the network, like if you want to restrict access.
The solution is deployed on-prem. I am an integrator of this solution.
What is most valuable?
The best features are the scalability and the license structure. The license structure is like a tier. If a customer doesn't actually want the highest features, then they can just start with the basic license package and upgrade it if their network is growing. For the smaller customers, they can start with the smaller plans and so on. If you have a financial customer or banking customer, they can go for the full features, and if it's not that critical, the customer can get the basic license package and implement that.
What needs improvement?
The licensing documentation needs to be better. We found some old documents describing the license names, like the Base license and Apex license. Cisco used both names. We have found that they changed the Advantage license and Premier License. If someone misunderstands that, they might end up with a hassle. I don't know if it's possible or not for Cisco to remove the older documents from the official website.
For how long have I used the solution?
We have been working with this solution for more than two years.
We were using two solutions on Cisco's network, so we had a few ISE plans in that network.
What do I think about the stability of the solution?
The solution is stable. We have maybe 4,000 users for the Next solution.
How are customer service and support?
We haven't used technical support very much, but in general, Cisco's support is always responsive.
How was the initial setup?
Initial setup was straightforward from our point of view because we have engineers who did that, so of course it was not an issue with us.
The accesses took maybe three or four months to complete, but the Next part took about three weeks.
For deployment and maintenance, the team was average sized. You need to follow the correct documents for deployment. There can be misunderstandings if you use old documentation.
What's my experience with pricing, setup cost, and licensing?
The licensing is subscription-based and based on the user account.
What other advice do I have?
I would rate this solution 8 out of 10.
I would recommend this solution.
If someone is looking for a concrete solution to control the access, then ISE is a better solution.

Great network access control lets you know who's in your network at any time
Pros and Cons
- "I've had no issues with scalability. I started using it on two campuses, and now I'm using it across the country and scaling it across subsidiaries in other countries."
- "The most valuable feature is network access control for the users coming into the network, which allows us to know who is in the network at any given time."
- "The intuitiveness of the user interface could be improved."
What is our primary use case?
My main uses are device administration, wireless access authentication, and ethernet access.
What is most valuable?
The most valuable feature is network access control for the users coming into the network, which allows us to know who is in the network at any given time.
What needs improvement?
The intuitiveness of the user interface could be improved. They could also make the deployment process more user-friendly.
For how long have I used the solution?
I have two years of experience with this solution.
What do I think about the stability of the solution?
ISE is very stable - since it was installed, I've had no issues with it.
What do I think about the scalability of the solution?
I've had no issues with scalability. I started using it on two campuses, and now I'm using it across the country and scaling it across subsidiaries in other countries.
How are customer service and support?
I've worked closely with Cisco for many years and have no complaints about their support. Sometimes it takes less than a couple of minutes to get through to their support team.
Which solution did I use previously and why did I switch?
I previously used Portnox, but it only gave us network access control, so we switched to ISE, which has more features like device administration.
How was the initial setup?
Deployment is usually tough the first time, though once you get it working, it works well.
What about the implementation team?
We used in-house engineers and an integrator.
What's my experience with pricing, setup cost, and licensing?
We have a three-year license. Standard licensing gives backup access and very few features, and then there's VM licensing - each VM we use needs to be licensed. VM licensing comes in different sizes: small, medium, and extra-large. There are also licenses for features, posturing licenses, and profiling licenses.
What other advice do I have?
Before deploying, it's a good idea to read up on the product first and then get some training so that when deployed, someone in the organization understands the solution. I would rate this solution as nine out of ten.
