I have never had any stability issues with it. It has been available 100% of the time that we have needed it.

The stability for our virtual machines is good if you follow the best practice and give it the reservations the virtual machines need, and you're making sure that you're following how many recommended devices are going to be authenticating to it. We don't have stability issues with ISE.

The stability is good. It is a cybersecurity product. It needs a lot of fine-tuning but that is part and parcel of the requirement. New things are coming, new technologies are coming, new softwares are coming but it is more or less stable.

My impression of the stability of Cisco ISE is that we don't have an issue with it, it's pretty stable. Even when things went down system-wise, Cisco was able to help us figure out what was wrong. So from my experience, which is limited because I only have one year of experience with ISE, is that it's been pretty stable.

Cisco ISE is extremely stable.

The stability is ten out of ten. We have not really had issues with it. We've had one or two small things, however, in the 12 years that I've been there, I've had very few issues with their platform.

It's now way more stable than 2.0 was.

Cisco ISE has consistently performed as expected, and we have not experienced any stability issues.

The solution is pretty stable. I haven't had any problems.

So far, I have no issues with the solution’s stability. My primary and secondary systems are working fine. I have the least to worry about. It has run smoothly for seven years.

The stability of the Cisco Identity Services Engine has continued to improve over time as the product has matured. Anytime you're dealing with something like a database product that has millions or hundreds of thousands of endpoints and entries in it, inevitably you're going to have performance creep over time. Because of the scale of the Cisco purpose-built UCS appliances, the SNS appliances that predominantly run identity services engine, we've seen an enormous advantage by staying up to date on the most current Cisco SNS appliances. We've also seen an enormous advantage by leveraging ISE in a hybrid capacity. So the ability to deploy PSMs on a hybrid cloud environment, on a public cloud environment, as either additional capacity or as a failover point for that on-premise install base is a really nice advantage to have.

It's been around for many years now. Since version three, stability-wise, it's been pretty reliable. We know the versions to avoid. We know the stable versions.  Besides some upgrades and that type of thing, it's generally pretty solid.

It works like a champ until you try to upgrade it, and then it becomes risky and fragile. I don't know whether that is because of the complexity of the architecture. We have what I would call a twin database environment. Where we're trying to keep two copies, at a great distance from one another, synchronized. One misstep and there it goes.

When it comes to the stability of the product, for the most part, it is stable. But when it breaks, it breaks on a grand scale as well. And that's why, for us, most of the time, we don't always jump to the latest and the greatest when it comes to software updates because we wanna make sure that the software goes through our internal change control and make sure that a lot of bugs have been ironed out and straightened out before we update. But even then, we are still running into unforeseen bugs and unexpected situations. But I'd say, overall, it's relatively stable.

We encountered a few bugs that were resolved using the SMUs. However, when the solution is built properly, there are no performance issues.

After I set it and forget it, upgrading Cisco ISE is the only thing to do.

One thing with Cisco is that we haven't ever had issues with stability, and ISE lines right up with that. We're using the virtual appliance and we're using VMs. We haven't had any issues there, as long as you know the caveats that go along with their setup.

There have been no issues as far as performance or uptime.

Uptime is great. I don't have a complaint with ISE with uptime. It's been a rockstar. As far as I'm aware, we have probably had 95 percent uptime, or even 99 percent. Nothing is 100 percent. When there's an issue, it's usually not ISE.

It is very stable.

I do not like the stability of Cisco ISE in the virtual environment. That might have been more of an underlying host issue rather than an ISE issue. But we've moved to hardware right now, and I wouldn't have looked back. The next place we're looking to explore is potentially in the cloud, but that's still up in the air because our environment is not small. We're one of the larger 700,000-plus endpoints.

For the most part, Cisco ISE is stable, good, and functional. However, when it fails, we are left clueless as to the reason behind it, and that's the frustrating aspect.

The stability is good.

Now, the stability is pretty good. I've been working on it since the product launched and it was a bit sketchy. Its current state is really good right now.

The only thing we have run into was a bug when we ran virtual appliances, but that turned out to be an issue with our storage networking QoS policies. That wasn't really an ISE problem, it was more of a storage problem.

The stability is good. There are no bugs or glitches. It doesn't crash or freeze.

Because of the numerous bugs we've been hit with, on a scale of one to 10, the stability is a four or five.

This is a stable product. The features that do work, work well, and we use it on a daily basis.

Once configured properly, Cisco ISE shows good stability.

We have never experienced any stability issues with Cisco ISE.

I haven't had many issues in terms of its stability. It doesn't really ever go down. Anytime we ever have any issues with it, it's usually human error.

It's very stable.

I rate the tool’s stability a six out of ten. It breaks down a lot.

The solution’s stability is good to go so far. Some vulnerabilities had popped up like any other solution, but Cisco remediated them. There was no problem.

The product is stable. We don't face many challenges. It's stable, so  I would rate it around a nine out of ten.

It's stable. We never had any issues.

Overall, it's pretty stable.

It's very stable for us.

It has been very stable. There's no problem with that, as we have redundancy in place.

The stability solution is really good. Once we get it up and running, it's great. We have to do a major upgrade, and I'm not as thrilled with the upgrades as I am with just a day-to-day job integration. Upgrades aren't my favorite thing.

Sometimes, they push an update that breaks the whole deployment. It happened to me with update two. It was my fault. I updated right after it came out, and I won't ever do that again. I will wait at least a month or two or three, because the update was taken down a week later.

I was lucky enough because I had updated from update one to update two. So it didn't really break the whole deployment, just parts of it. But they fixed it in a week with update three, so I was able to put it back together. Roll back is also always an option.

The stability is fairly good. Since we went to the 2.6 version, it has been a lot better.

So far, from what we've been using, we haven't had any problems even with any of the additional patches that we've added. It has been great.

Cisco ISE is extremely stable.

Like most products, as Cisco ISE evolves with different software versions over time, it becomes more stable and feature-rich. Initially, when it first came out, it was playing catch up with other vendors and solutions. However, now Cisco ISE is probably at the forefront of Open NAC solutions.

Cisco ISE is a stable solution. We haven't faced any major issues with the product.

With patches and a little bit of babysitting, it is totally stable now.

ISE is pretty stable. If it does have an issue then you need to call TAC and work through the bug in it. They are very responsive and very quick to help us eliminate the issue and also come up with a plan, such as how to move forward with additional issues or different things that are coming down the pipe with Cisco ISE. When you're talking to them, you feel like they are a partner and not just a disconnected entity.

The solution is highly-stable. I rate it a perfect ten.

I've had no issues with stability.

If you have someone taking care of it, it can be quite easy to manage the solution. Otherwise, if you don't look after it and take care of it day-to-day, then it will become more complex to run. However, if you have someone taking care of it, maintenance is not that difficult.

The stability has been perfect. Our company has been using it for more than 10 years and it's stable. It's really good.

The stability of the solution is a 10 out of 10.

Its stability is great.

I've had very few issues with stability and haven't run into any bugs.

Cisco ISE has come a long way when it comes to stability. It's getting better.

So far, we have had no issues with the stability. 

The solution is stable.

There are no stability issues with version 3.1.

It's stable but there's a limitation of up to 200,000 users. If you have a big number of users, then you have to customize the installation process. 

The stability of the solution needs to be improved. It's not ideal. It's lacking overall. If we have five or six items activated, the box shakes and we're scared to touch anything. When we do have to reconfigure things, it's a nightmare as it can go down and it can take us a day or two to sort things out.

We have been using it, especially during alternative working arrangements (due to the COVID-19). Using it, it's been stable. We have not had any issues. The only reason we are looking to upgrade is we didn't know the benefits that the newer version offered. When we checked with Cisco, they advised us that we were missing a few items that actually gaps caused by the partner's setup which we realized we missed during the health check.

We haven't had bugs or glitches. It doesn't crash or freeze. It's good.

The solution is stable. I haven't witnessed bugs or glitches. It doesn't freeze or crash. It's reliable.

In terms of stability, they are rock solid. If you set the policy and you implement it, it's not going to break.

If the customer has more than 200,000 users, the performance becomes a bit laggy.

It is stable. Any time we found an issue we would get in touch with the reseller to help fix it. Then they tell us where the problem is and we'll know where to look. 

ISE is very stable - since it was installed, I've had no issues with it.

The solution is stable.

It's very stable.

It is stable.

The solution is stable. We have maybe 4,000 users for the Next 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.

Cisco ISE is stable.

The stability of the solution is pretty good. I've only had a couple of issues.

The stability of the solution depends on how you scale it. If you have set it up properly, it will be great. If you put all your eggs in one basket, in one part of the network, and that goes down, then you have lost everything.

It is very stable. I would rate the stability as 10 out of 10.

It's really stable.

This is a very stable solution with many integrations.

A co-worker of mine had some issues with the solution crashing unexpectantly or some processes went down. 

I have had a very good impression of its stability.

ISE is stable.

It is stable and scalable. We have 5,000 to 6,000 users. 

The stability, from a users' perspective, is very good. I haven't encountered any issues before, and we've used it for quite a long time. It doesn't freeze. It doesn't crash. There aren't bugs or glitches. It's pretty reliable overall.

I rate the solution’s stability an eight out of ten.

The solution is stable. 

Cisco ISE is very stable.

The solution provides excellent stability and reliability. There are no bugs or glitches. It doesn't crash or freeze. 

The solution takes a while to get up and running before it becomes stable. There is a lot of fine-tuning that needs to be done to make sure that users are authenticated properly and not denied access. I have had the experience of redeploying the ISE several times because of false denial of services or access to services but once it is configured correctly the stability is fine.

It is stable.

It's very stable. We have it in on a big car rental company. We manage and we support the Cisco ISE platform for them. It's very stable and it adds a lot of value to the network.
