Its stability is good. Stability-wise, there aren't any major differences among Azure WAF, OCI WAF, Google Cloud Armor, and Fortinet FortiWeb.

FortiWeb is highly stable. I can't recall an instance when we've had any issues. Our services are used constantly. For example, we have a fraud prevention tool that various banks and FinTech companies access, and FortiWeb is deployed behind it. We've never had a problem with availability due to FortiWeb. The solution is 100 percent stable and available. 

The version we use is stable and reliable with no issues. 

It has been reported that the latest version has some stability issues. 

FortiWeb is highly stable. We haven't seen any bugs. The solution is reliable once configured properly.

FortiWeb seems to be stable so far. 

The solution is very stable. 

The stability is a 10 out of 10. We haven't had any issues.

The stability is good.

This is a stable, reliable solution. There are no bugs or glitches. It doesn't crash or freeze. 

The solution is stable and I rate it an eight out of ten. 

It has been very good. In the time we've had it, we've had only one issue when they had some sort of outage for themselves that affected us. That was the only one that I've encountered so far.

The solution is stable. 

There are no complaints on our side. The performance and stability are fine. We used to have a cluster of two appliances. Everything seems to be fine when we update the firmware. We haven't had any issues.

The only instance where we have had issues with stability was a recent one where the solution was blocking some websites that we did not intend to block and which were even whitelisted in some instances.

Our partners explained that this happened because of an issue with the SSL setup. I'm not sure if they then sorted it out or if they just switched off that functionality.

But for the past 10 years that we've used it, that was the first error or problem that we ran into. Maybe it was just teething problems since we only deployed it end of last year.

Sometimes it is not as stable as it could be. We've had some issues. Sometimes the loading will be disrupted for no apparent reason. It might be due to the WAF.

The product’s stability is normal. I rate it six out of ten.

The solution is pretty stable. I'd rate it a three out of five in terms of stability. Sometimes the upgrades don't go as smoothly as we would like. 

Stability is very important and yes, the product is stable.

The stability has been good over the years. It does not crash or freeze. There are no bugs or glitches. The performance is reliable. 

Based on what I know and see during the testing mode, it is stable. There has been no major incident. It has not stopped during this time.

In my experience, it's mostly stable. But, when new versions come out, we've found issues. It seems like new versions fix some problems from older releases, but they also introduce new issues that we have to discover later. So, I'm not a big fan of always going to the latest and greatest version, particularly with Fortinet, since this might be a newer product area for them. 

I need to be very careful with availability and reliability when upgrading versions. In comparison to vendors who have been in the business longer – like AWS WAF, or even desktop solutions with more experience – those tend to be more stable. They've been around longer, they've seen more issues, and they've fixed them. 

So, FortiWeb's stability is a bit… it depends on how you use it. Let me put it that way. If you want to use something more advanced, be prepared for potential issues.

I would rate the stability a five out of ten because we've encountered a few issues that weren't great. We only discovered later that they were bugs in the system that would get fixed in future updates. So, Fortinet needs to work on that in my opinion. There wasn't the level of thoroughness I would have expected. 

I think it's quite reliable so long as it's configured. 

This is a good solution, stability-wise.

We haven't had any issues with it so far. 

As a hardware device, the solution is very stable. This is true when compared with other web application firewalls. 

FortiWeb is a stable solution.

Stability is very good.

In the first few months, we had some issues but with a custom patch, we are good.

This solution is stable and w have had no issues with its stability.

I have not yet encountered any stability issues.

I did not encounter any stability issues.

It's very stable. I've never had any issues. 

I've never seen any issues, but when you turn on all the features or every single scanning, that's when it slows down a bit.

Its stability is fine wherever we have implemented it.

It's a stable solution and we run it 24/7. In the past five years, we have had four cases where there were some inconsistencies with the firmware. There are times where we experience crashes because of issues with the firmware.

It's really stable. There was only one issue in the past two and a half years and with the help of the technical support from Fortinet, it was quickly fixed.

This is a stable solution. 

FortiWeb is a stable product.

It really is a powerful WAF; more than one year running with no stability issues.

Fortinet FortiWeb has been extensively used by us previously, but we are going to decrease the usage now because of cost. 

One of our customers recently experienced a stability problem. The customer has two FortiWeb appliances in an HA cluster (A-P). Something happened and both FortiWeb units became MASTER. Only a reboot of one of the units helped them. We opened a ticket.

Fortinet FortiWeb is stable. It is able to detect the latest vulnerability from Log4j that happened on The Verge.

The solution's attack signature receives its update from Fortinet Developer Network, and many of the updates are immediate. The attack signatures are updated regularly due to the connection to Fortinet Developer Network.

I have not encountered any stability issues, but it always consumes a lot of memory.

So far, the stability has been okay.

The solution is stable.

It is stable. You obviously need to assign and write configurations correctly.

The stability is okay, sometimes. It could be more stable.

We have encountered very few stability problems. In six years, we had one device that need to be shipped back to Fortinet. We had HA set up at that location, so there was no down time.

We did not have a problem upgrading their firmware updates.

The stability of the product has been good. There are no bugs or glitches. It doesn't crash or freeze. It's reliable. When you look at the specs and if you do what they say in the specs, in terms of ensuring that you're not overlooking anything, it's a good product.
