I rate FortiGate nine out of 10 for stability. 

I would rate the stability of Fortinet FortiGate an eight out of ten. 

FortiGate is now stable. We experienced some difficulties in the beginning, possibly due to some bugs we encountered. However, for approximately the past six months, we have been closely monitoring various ratings for FortiOS versions. As a result, we are currently running only on mature versions. Since then, we have observed that the device is significantly more stable than before.

The solution is very stable. It is a robust unit.

Whenever we install a new release of an OS we should expect lots of bugs on the system that could break the system. Something that is working fine in the previous system, if we upgrade it, it could break it. Fortinet should work a lot on this to remediate it before releasing any OS. This includes any update and upgrade of FortiOS because I have seen issues when I upgraded, such as the memory and CPU jumping to 100 percent, and some or all functions were not operational. These bugs should be fixed in the firmware.

If there is a need for some upgrade or update on an existing system then I will plan ahead, but if it is not stable I will not do it. We have new releases being tested now and once they are rated stable I will upgrade.

It's stable.

Secure SD-WAN is stable, but when it comes to the firewall, sometimes there are issues with the throughput and related factors. Improper handling of these can lead to a memory surge, a well-known bug that can cause the entire system to freeze. When this happens, the system appears to be running but no traffic is processed, causing disruptions to applications, users, and overall internet connectivity. This can be confusing because the firewall appears to be functioning correctly. Typically, the solution is to restart the firewall. However, when we contact support, they require logs before restarting, which can be challenging in urgent situations. As a result, we prioritize quick resolution over troubleshooting. This is a common drawback of the operating system.

The solution is very scalable and reliable. There are no bugs or glitches. 

FortiGate is a very stable product.

I would rate the stability of Fortinet FortiGate ten out of ten. As long as we configure FortiGate properly.

Fortinet FortiGate is stable. I have not encountered any performance issues.

The solution is very stable. You don't have to worry about bugs or glitches. I tend to wait and not upgrade to the latest version right away to ensure this is the case.

I would rate the stability of Fortinet FortiGate a ten out of ten.

I rate FortiGate an eight out of ten for stability. It is less stable than Palo Alto Networks and Check Point firewalls because there are lots of bugs in the latest firmware. 

The solution is pretty stable and reliable. There are no bugs or glitches, and it doesn't crash or freeze. 

I think FortiGate is going to be around forever. If I don't see their stock price double in the next two years, I'm going to be surprised. I think it's a very underrated solution. 

I rate the stability of Fortinet FortiGate ten out of ten.

I rate the stability of FortiGate an eight out of ten.

Fortinet FortiGate is stable which is why we have stuck with it for almost 12 years.

I'm happy with what they got. It is a great product. Sometimes, you're going to get a lemon—the way it initially happened with FortiAuthenticator 300F—but that doesn't happen very often.

If there is a problem, the next business day, they send it and get the replacement, and they help me configure it.

It's very stable.

The tool is stable. 

If you have the firmware version 6.4.3 and are using FortiLink in VLAN, it has trouble with tunneling networks for a wireless network. It won't give it a route to the internet. I found it just last week. There was a version back in 6.2 where it required 12 characters for the password of a wireless network on Web 2.0 as opposed to the traditional eight characters. The problem came when you wanted to edit it. If you upgraded to that firmware from a previous version, it wouldn't let you save any changes without changing the password, making it a requirement. That was kind of problematic for a while, but for the most part, it has been pretty stable and responsive.

I've only experienced stability issues a few times.  One was with the v5.4.0 and .1 releases. Also, there was an issue during the v5.2.x series where there was an SSD issue that was fixed with later firmware. Overall, the devices have been very stable.

I'd rate it a seven out of ten in terms of stability.

I rate FortiGate an eight and a half out of ten for stability.

It is stable.

Their devices are quite stable. We have not had any problems with the operating systems or maintenance of subscriptions. It is a robust device.

It has been very stable over the past two years.

It is reasonably stable.

Fortinet FortiGate is approximately 80 percent stable.

Fortinet FortiGate is a stable solution. However, my issue is the performance only. When I use all the profiles, this affects the performance. From the beginning, I should have had a better sizing of the box.

Stability could be improved.

The solution is quite stable. It doesn't give us issues. There are no bugs or glitches. It doesn't crash on us. It doesn't freeze. It's reliable. Fortinet has created a really reliable solution.

The solution is very stable.

I haven't had any problem with the stability of the product.

This is a good, stable solution. 

Fortinet FortiGate is highly stable. It has high availability.

Fortinet FortiGate is a stable solution.

The stability depends on the FortiGate model. You need the right model for the amount of GB traffic. If a customer deploys a smaller model on more traffic, there may be issues. Otherwise, it handles traffic well. Overall, it's a stable solution. I'd rate stability nine out of ten. 

Apart from the disruption in the service because of the IP address change, it has been quite stable.

It is a stable product. We had some issues in the beginning while setting it up, but we received an update of the firmware, and since then, it has been stable.

Its stability is okay for us. Since we have put this new cluster, we haven't had any problems or crashes. It's okay for us from this point of view.

We got this firewall just less than a year ago, and we hope to see good performance in three or four years.

The stability has been excellent. It's very reliable and the performance is great. They have not failed in three years. There are no bugs or glitches. It doesn't crash or freeze. 

Fortinet FortiGate is stable. It's used across all the countries, this is the way most multinationals run their system.

It is 100% stable.

Fortigate firewalls are very reliable- in the past 15 years I believe only 2 devices in a 100 have failed.  The failures were due to harsh environments (dust and water will ruin any electronic device).  The input I can give to any technology person or client looking to choose a firewall / threat management device I would highly recommend the stability / reliability of fortigate.  Once installed it will do it's job efficiently and effectively for several years.

Fortinet FortiGate has high availability, which means that we have deployed two firewalls. In case of any failure of a device, the other one will continue to work. Our university stays online 100% of the time.

Fortinet FortiGate is quite robust. I haven't had any kind of hardware issue. The system has been running very smoothly with all the upgrades as far as I have continued my support with Fortinet. We keep renewing the support every year, which gives us the eligibility for all the updates.

There is no downtime with this solution. The last time the users could not connect to the VPN was an issue with the internet.

I am sure there are bugs or glitches from time to time, but it's not anything that's been problematic or had multiples where it's been an issue.

Fortinet FortiGate is stable.

I would rate stability a nine out of ten. It's a stable product. For the most part, it's very reliable.

The solution is stable. 

Fortinet FortiGate is a stable solution. The main risk was the devices and systems that the end-users are using, whether inside or outside the network. The VC was not secure enough. This causes some threats to our headquarters servers.

The product is very stable. It's a powerful product.

It is very stable. When you compare it with Palo Alto, it is stable.

The product is stable. Normally we are selling Fortinet for customers who have 100 or 150 users, not more than that. Over time, there is a lot of worry about insecurity. For big accounts, we are not able to satisfy the customer with the Fortinet firewall because they ask for a lot of features. Even in PLC, we have some challenges in that.

Stability has been fine. I've had no questions about the stability of it. It seems so far it is staying up. I haven't had any issues to speak of.

Small models (up to FG-90) are build on SoC (System on a Chip), so they need to be mounted in places with enough airflow and right temperature, otherwise they could hang, slow down traffic processing, but more often you just can't log in to the device's web-interface (reboot won't help you until it cools down). Actually, that's not an issue. It is a technical requirement for operating environment to be 5-40 degrees (but at 35 degrees with poor airflow there may be issues mentioned above).

Fortinet FortiGate offers good stability. I have been using it for around two years.

Fortinet FortiGate is a stable solutions. Other solutions, such as Palo Alto, Cisco, and Forcepoint are less stable.

The stability has been great. There are no bugs or glitches. It doesn't crash or freeze. It's reliable. 

Fortinet FortiGate is pretty stable.

It is hard to judge this year because of everybody working from home. Everybody is using up a lot of bandwidth so I'm not sure if that is a cause for some of the instability with the Forti client. The only place we've seen instability would be updating Forti client with their software called EMS.

So pushing out the client with EMS, like a client update to remote users, has proven a pain in the butt. But that could be because the end users' VPNs are maybe a little bit unstable just because of the high bandwidth demands. It is hard to determine. Maybe it is because some of these users are in remote areas, or non-urban or smaller towns, as opposed to being in an urban area where bandwidth is a little better.

We never jump ahead and say, "Oh, yes. 6.5 just came up. Let's jump on that." We'll probably just wait six months and see what goes on first. And I guess that's probably what a lot of people do because it's protecting your intellectual property and everything which that company owns.

I'm not saying that there's no instability. People will generally just wait and not jump out unless they're testing in the lab. They're not going to jump out and put the first revision that comes out on their firewalls.

Stability-wise, they are good at the job of a data center firewall. For a perimeter firewall, it is for smaller customers, preferably.

No issues encountered.

It's a very stable product.

I found Fortinet FortiGate to be a stable product.

FortiGate is a highly stable system.

The stability is very good in Fortinet FortiGate. If there are bugs or problems the issues are fixed quite quickly with updates. Palo Alto has a similar level of stability, they support their appliance from updates to the OS.

FortiGate is a very stable firewall.

If I compare with the open source, it has really frustrated me for a couple of things. Whenever my students or faculty goals increase, then in Fortinet, I need to change the model for going with the higher model, or better model more better first tier it can deal with it.

The solution is very stable.

We're happy with its performance. I would rate it a 10 out of 10 in terms of performance.

Overall stability of the solution is good. I am totally dependent on this device. Basically, it's deployed on the edge of our network. All the software and HR, admin, every department is behind this network. And every user connects their internet services via the VPN. 

The solution is very stable. That's not a problem at all. There aren't bugs or glitches. It doesn't crash or freeze. It's quite reliable.

There are some bugs you have to deal with. There's some troubleshooting that needs to be done. 

Before version 6.0, FortiGate's firewall performed well enough, but lately, they've introduced so many features. After that, its stability has been somewhat lacking. This is because they're constantly updating their firmware. So it was pretty stable, but nowadays, it's not that stable.

I have had no concerns with the stability so far.

No issues encountered.

In terms of stability, there are some areas in which they need to improve. There are different versions and we understand from past implementations which will work best according to our client's needs. The wrong one may not be as stable as they would like. 

Its stability is quite good.

There are some stability issues when move to a newer version. It's always good to be a couple of steps behind when you upgrade as usually the latest major releases are a not stable. We are quite cautious to update.

They are pretty stable. We never had any real issues with them.

6.4.2 is our current version. The latest is 6.4.3. It's available like I say, however, we have not installed it. We'll wait until around December, then we will then install that one. We like to wait to witness its stability. Once we know it is bug-free, then we allow it to run as the latest platform.

Fortinet FortiGate is super stable, one hundred percent. Just works 24/7 without any issues like you would expect from an enterprise product.

It is stable.

We have not encountered any stability issues. Stability has dramatically improved over the previous main version branch of FortiOS; 5.2.x and 5.4.x are stable enough for critical environments.

It is used on a daily basis and in general, stability is okay.

There were two instances where the memory was full and the WLAN was blocked. The system had to be restarted. This may not have been a problem directly related to FortiGate. It may be that I didn't have enough to support the product. Perhaps a larger model would solve this issue.

It is stable, and I don't see any cons of this. 

In m company there are around seven technical engineers required for deployment and maintenance.

Fortinet FortiGate is very stable. We use it for 20 hours a day only. It is a firewall so it cannot be shut down.

Sometimes we found that the traffic to the internet froze, I don't know exactly the reason. The only way to get it to work again was to turn it off and then run it again, a hardware reset. Overall it is a very stable platform but sometimes there is this problem.

There were no issues with stability.

I never encountered any stability issues. It is a very stable product.

No. I always used the latest qualified-stable firmware recommended by Fortinet and check by own testing methods the stability of HW and SW before deploying anything into customer premises.

There were quite a few problems with the stability of the system but now it's working fine. I think it had to do with the complex environment, not because of the product itself.

I'm satisfied about the stability of this solution.

Since we have been using FortiGate there haven't been any major problems so far. Especially nothing too serious like a major bug or anything like that.

The only issues that we have come across have had to do with simple configuration errors like missing configuration values from a previous implementation.

It's a stable project. We plan to keep using it.
