It's about 95% stable, not perfect, but quite reliable.

The solution is very stable.

It is stable. I would rate it a nine out of ten in terms of stability.

The stability of pfSense is exceptional. I've only encountered one instance of hardware failure, which was due to an electrical issue. Otherwise, all other deployments have been reliable. I would rate it nine out of ten.

Stability is not a concern. I've enabled the HA features, and spread them across multiple ESXi hosts. The only thing that could take down my network, would be a lack of power to the hosts, or all of my ISP tanks at the same time.

Everything is very smooth, with a user-friendly interface. You can use the user interface or CLI as a command.

I've experienced certain issues with Netgate pfSense in the past, particularly with the previous version, which was 2.5. It posed several problems. However, the current version appears to be more stable. Nonetheless, I still encounter troubleshooting challenges. For instance, there is an issue where it initially blocks an IP range but releases it after ten minutes. This behavior is somewhat peculiar, and it pertains to IP filtering.

If I think about pfSense, I would rate the stability around six. There have been some issues with stability, causing occasional downtime. I haven't extensively worked with pfSense in the last year, so my experience is limited.

pfSense is stable. 

Not very stable.

I've had no issues with stability whatsoever. I'm quite happy letting it run for days, months, weeks, et cetera. We have no requirements to actively manage it. In terms of performance, we just need to go in and make changes as required by the customer. Other than that, it's set and forget. There are no bugs and glitches to navigate. It doesn't crash or freeze.

pfSense is very stable. My own disappointment is the appliance only worked for a year and two months. It might be just bad luck, but that was very disappointing.

I had to use pfSense Community Edition on a general desktop. That was done within three hours. It took me three hours just to get the hardware, download the software, and then set it up to get everything working again. 

After that, I ordered the new server with two servers: one has to be active and the other standby. I am going to try higher scalability on it using pfSense. 

The configuration is already on the servers. I did all this myself because of my experience. The utilization of the CPU, etc., it's very low. 

I like pfSense. It doesn't take too many resources and it's very stable.

It is stable. I would rate it an eight out of ten for stability.

The tool is stable.

It is very stable. Both pfSense and Netgate appliances are very stable. I have had some of these solutions working non-stop for about a year and a half.

I rate the solution’s stability a ten out of ten.

The solution is stable.

The stability has been great so far. there are no bugs or glitches. It doesn't crash or freeze. Its performance has been great.

It is working fine for me. I never had any problem with this firewall.

It is a very stable product.

The stability of the solution is very good. There are no bugs or glitches. it doesn't crash or freeze. Its performance is reliable. It's been very good over the years.

It is very stable as long as you don't change the winning theme. When it is working, leave it working. My rule number one is one computer, one function. So, pfSense does that one function, and I don't try to use it for anything else. I could do some File Transfer Protocol or things like that, but it is not made for them. I don't restart it and move it. I only do the security updates and change the username and password very often.

It is stable.

The solution is pretty stable, that's why we use it. There aren't any problems.

A little... BUT, this was contributed to a failing Arista switch that would do a coredump and reboot. The pfSense installation at high speeds failed over perfectly though.

It has been pretty rock solid.

The solution is very stable. We've had zero issues. There aren't bugs or glitches. It doesn't crash or freeze. It's been reliable.

We have not encountered any stability issues and have upgraded to each version over the years. They've really made a rock solid solution.

It seems to run stable, as long as the hardware is good. I tried running pfSense on a USB flash drive. After a month, I was having to re-install/re-configure pfSense on a new flash drive. I did that for a couple of months and collected a bunch of broken flash drives.

Even though their online documents claim that pfSense can run on flash drives, it really just breaks the flash drive after a month or less.

Sometimes there are issues with package deployment and one must refer to the forums for support.

The solution is stable. Since last upgrade there hasn't been a crash, freeze or need for reboort. It's quite reliable.

It's a stable solution.

The solution is stable.

Stability-wise, it's fine. I've only experienced one issue in the last 10 months. But in general, I am happy with it. Scalability-wise, as I said, our organization is just about 10 to 15 people, so we have not had much of a problem. I can't comment on how it would scale up with hundreds of VLANs and tens of thousands of people operating on it. But in general, for a small organization, I think it's very stable.

The stability isn't bad, but there can occasionally be bugs within the system. The likelihood is lessened if you follow a few key protocols.

It's important to have a proper license, otherwise, you run the risk of bugs.

It's important to upgrade the solution regularly. This also helps users avoid running into bugs. If you experience a bug, it's a good idea to check the release and make a grid.

Those that have experience in troubleshooting will benefit from their knowledge when using this solution. Sometimes packages will not work and you'll have to be strategic with workarounds.

I am satisfied with the stability.

I got terrible kernel crashes on HP laptops while trying to setup WLAN, but it worked better on Fujitsu ones.

The stability of pfSense is standard. It is rated as one of the good solutions in this area.

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

The product is stable. There are no issues with bugs and glitches. It doesn't crash or freeze. It's reliable. 

I've never had any problems with stability. You plug it in, set it up, and it works.

This solution is stable. 

The stability could improve.

That's the fun part. It's completely reliable in terms of resources that it needs to run. In terms of stability, once it's configured and properly tuned, it will do its job. Still, with firewalls these days, you can't simply configure and forget — it's not like that. You have to look into it every day or every once in a while and if any new traits or new protection mechanisms need to be built, upgraded, or re-tuned, you have to do that. Otherwise, the platform is rock solid. It doesn't fail.

This solution is good for small businesses but it is not as stable as other competitors such as Fortinet.

pfSense is rated as one of the good solutions in it's field and stability is good. 

This solution is absolutely stable. With some systems there's a necessity to regularly redo the configurations inside the system. With Pfsense that's not the case. I have no issues with it at all. 

Companies in Africa have issues with budgeting for IT. An open-source solution like pfSense gives us stability and provides us with good reports. It's amazing. It makes the solution reliable.

I depend on and use VMware ESXi with vSphere in my deployment, virtualization. pfSense is more stable and reliable if you install it directly on the server, i.e. not being installed as a virtual machine. That makes it very stable.

I rate the product's stability a nine out of ten. 

I'd like to see its stability improved. I know the BSD Kernel is more capable than what pfSense provides at this time.

Stability has been excellent. We have experienced no issues; it never fails.

Our appliance is under constant heavy load by several services, and it's rock solid stable.

I had stability issues only with a GUI that used to hang. It didn't affect any services, but it was a little annoying that we needed to restart the PHP often.

The solution is stable.

It just works.

Never had any issues. In fact, I've had a pfSense firewall with the uptime of a year.

We had a stability issue. A handful of times the firewall box froze and needed a power cycle.

Rarely and almost always due to bad configuration or failing hardware.

We did not encounter any issues with stability.

No, in fact I have one more than 4 years ago in production and it works perfect

Yes, sometimes there are issues if there are some complex configurations. When working with load balancing ADSL modems, I've noticed that pfSense "fools" the modem and it becomes unresponsive until it is restarted. This issue doesn't affect pfSense, but it is the root cause of a hung ADSL modem.

This is a very stable solution.

PfSense is stable.

The stability of the solution is very good. My only complaint is when there is a power outage pfSense requires a manual reset.

Stability is great. That's a strong point.

The solution is very stable. There are no bugs or glitches. It doesn't crash or freeze. It's excellent.

We never had any stability issues, even during high load usages.

The solution is stable. 

pfSense is a very stable solution.

The stability is rock-solid. 

Close to none. One time, while upgrading, the system crashed and had to install from scratch. After some research, it was due to an unsupported package that I had installed which the new version didn't like. I just installed and restored my configuration and that was it. No biggy.

We've had no issues with stability.

There were no stability issues.

There were stability issues with certain versions, but fixes were released and the right hardware helped.

No, I didn't have any issues. Every issue I had with pfSense was with hardware (not caused by pfSense).

There was an issue with the Layer 7 filters on an old PC.

pfSense is a stable product.

This solution is stable.

pfSense is a stable solution.

The stability is very good.

The stability is very good, it's just that it's not as easy to use as SonicWall. There are limits as to who we can put to work on the solution, a limited number of our engineers work with it.

Just once. One of our customers had an issue with their electrical stability. The electrical supply was jumping, and playing about, and when it was happening pfSense stopped.

No issues encountered.

It is a stable product.

In the last two weeks, we moved a few resources to the pfSense and it's been stable. 

When compared to SonicWall there were some issues but it could be that SonicWall was doing too much. It was doing almost everything. It was doing IDS, IPS, and contextual training. It may be that it was overwhelmed.

The stability of the product is very good. We haven't had any issues. There aren't bugs or glitches. It doesn't crash or freeze. It's reliable.

The stability is questionable. There are glitches. Since no one is really managing the solution, and no one takes ownership of it, there aren't many fixes that happen on it.

No issues encountered.

I consider it very stable.

With regard to this configuration, I consider it a stable solution.

There were no stability issues. If there are issues, they usually stem from a hardware fault.

Not at all.

We've only had to do one reboot in six months.

There were no issues during the time I used it.

It seems to be relatively stable. I haven't had very many issues.

If I do have any issues, it is more to do with the way that I have configured it. Other than that, it works fine.

The stability could be better. 

The stability is good.

I've never had any problems.

No issues encountered yet.

None

I believe that the issue of stability that we encountered was linked to our hardware limitation. For example, we would need to soft reboot the system manually after a power failure to get the DHCP functioning again.

When they make an update available, the problem is that pfSense service packages are not updated, it's just the OS. The pfSense OS is stable, but if the service packages are not updated to their new version when the OS is updated, we can't use those features.

Absolutely not, as the product is stable like a rock.

I have found pfSense to be stable.

pfSense is quite stable. It is one of the pros.

We had no issues with instability.
