Overall, FortiMail is a stable email security solution, but I did encounter a specific issue in the past. There was an instance when the appliance became inaccessible. This issue seemed related to the appliance's durability, as it entered a conserve mode due to performance concerns. Consequently, email traffic ceased to flow through the appliance during that time. To mitigate this problem, we increased the threshold for email traffic, ensuring that the appliance would not enter conserve mode and that emails would be delivered reliably even during peak loads.

The product is stable and I would rate it a ten out of ten. 

I don't remember if I faced any downtimes when using Fortinet FortiMail Cloud.

This product is stable. I actually do not remember the last time I restarted the server or where I have done restarts because of performance or had the system hang. So it is stable, but you need first to do a good assessment to know which product license you need to use. For example, the first time the consultant we used proposed a level of service that was lower than the specs of the one I have now. I disagreed on that at the time but the consultants said it was the better way to go. So we did what he said and it didn't work. If you do a good assessment in the first place you get to work with a stable product. For me now, the product that I'm using is stable and it was only unstable earlier because the assessment was faulty.  

The parts you need to get for a hardware upgrade are very easy to find and inexpensive. It isn't very complex to install them to upgrade. Just put the parts together and upgrade, if it is better it is worth wait. If it doesn't work and there is trouble, you can easily just return back to the old version.

This solution is stable. Currently we have four people managing FortiMail. This includes one IT person in the U.S. and three in Hungary. They watch and fine-tune the solution.

The stability is good, we haven't experienced any problems.

We use this solution every day. The company works also in Arabia, and Qatar, so we work Monday to Monday. There is no stop in service.

The solution is stable and reliable and the performance is good. There aren't bugs or glitches. 

We have not had any issue with the device. It's very stable.

Stability-wise, I rate the product an eight out of ten.

We haven't had any issues with stability.

This solution is stable.

This is a cloud-based solution with a data center, so if site one goes down then site two will continue, it's always available. All of the vendors are this same in this area.

In general, it's a stable product. I didn't face any incident that had to stop my business. It is always running with high performance. It is reliable and can meet our risk needs. You can say it's a good product.

This solution is stable.

It's a stable solution, we have never had any downtime or any complaints from the client.

I am happy with the stability. We haven't had a bug or a crash yet. Normally, it's set and forget, and we don't have to worry about bugs or anything.

I haven't been using this solution long enough to discuss stability.

This solution is pretty stable, overall.
