The configuration and access VPN functionality in OPNsense are satisfactory and work well. Currently, I prefer using Azure Firewall for my firewall needs, even though it might not be the absolute best option. My preference is due to a lack of experience with other Windows-based solutions.

We used to use Cisco or Nortel Solutions. We also worked with Linux. It was very manual in terms of configurations.

I used another one a long time ago. I don't remember the name. I went for this because it has an open license and a lot of people use it. I don't remember why, but I prefer this one over pfSense.

I’ve used pfSense and openWRT before.

A few years back, cybersecurity was not a problem for small and micro businesses, but since 2019 or so, that has seen a massive uphill, then, we were using built-in features of different types of OS-level firewalls with basic filtering, blocking the ports, orchestrating based on local FQDN based filtering, NATing, few BIND/DNS based filtering, implementing proxy's like Squid, etc. Best since these techniques are not good for business, we have to find other methodologies to protect clients' environments. Till recently, we also tried using Hardware firewalls, which most of our clients did not like because of known/unknown reasons.

I have experience with Cisco as well. I moved to OPNsense because it is free.

As technical people, we have used many solutions previously for our company and customers. For customers, we have used Fortinet, Palo Alto, and others.

I didn't switch from Palo Alto to OPNsense. I use OPNsense because Palo Alto is used for enterprises. For me, I prefer open-source products. It's more flexible for us.

I use Fortinet before in another company.

I have used FortiGate. For security reasons, we moved to OPNsense.

Before using OPNsense, we used Cisco Fortinet. Other solutions are more expensive than OPNsense.

We are using several VPN gateways. We are using our primary solutions in our company, making all the IT for the complete caller group. The caller group has around about 1,600 people in 10 companies. They are part of this group. We have one, main office and several branch offices.

We are using Juniper SSG Firewalls for Site2Site IPsec connections to customers and this Equipment is working really good. Unfortunately this devices will be running out og supprot soon, so we have to look for some alternatives.

The central equipment we use is Sophos UTM/SG and Sophos XG configured as high availability. The branch offices are connected by Sophos RED and we mainly use Sophos RED 50 with the AP 55 access points configured as WPA2 Enterprise. For central management, everything is managed in the main office. We are using SMTP proxy with anti-span and anti-virus on SG solutions. This is the only one that doesn't work because we have a problem in that our exchange users are too many, and there are too many accounts - this fact caused the Appache runnig out of ressources.

An example would be if you have one workstation with two smartphones, and each person has maybe three or four sessions opened on the exchange. If you have 1,400 accounts, you can reach 8,000 sessions. If the Appache message scoreboard is full is comming up, no further users can connect. We have contacted Sophos support to solve this but they were not able to do this - the only effect was a correction of the sizing guide from Sophos. 

I used pfSense before using OPNsense, and OPNsense covered most of my environment's needs. My organization uses only one firewall, and that's OPNsense.

We are also using pfSense.

In the past we used pfSense. We have also used Sophos and Palo Alto Firewall but have replaced many of these solutions.

We did previously use another solution, but I don't recall the name. We didn't like the performance we were getting out of it.

I have experience with Check Point and other products like Fortinet. They're different types of tools for different purposes. 

My experience is that OPNsense is great for installing and setting up, and then I almost forget about it. It is a good tool for everyday use.

If I require many site-to-site connections or prioritize advanced features, I might look at the other products.

I primarily work with FortiGate, but I am currently dabbling in OPNSense to see if I can learn it. I've also installed Cisco in the past, as well as Sophos.

FortiGate is a better firewall but that is commercial software that you have to buy a license for. OPNsense is suitable for small to medium-sized businesses. FortiGate is definitely quicker to install because you just buy the appliance. It's also more user-friendly.

If you dabble a bit with OPNsense, it can do about 90% of what FortiGate can do, but FortiGate is more user-friendly. Of course, with OPNsense being open-source, it will always beat FortiGate on price.

I think that with FortiGate, it is easier to log a support call. I haven't really needed technical support for OPNsense, but I know that FortiGate has the score logging facility, whereby you can just quickly log a call. There's also support in South Africa and I know company people that I can just call for help with FortiGate. But with OPNsense, I haven't really had a complicated setup, so for me, it has been okay and it hasn't been an issue.

The SD-WAN is also better on FortiGate. I think that they are heavily focused on security, so they might have better application profiles and other things, such as application threat detections.

Although about 80% of our clients ask for FortiGate, some of our clients ask for Sophos instead. For example, there are some banks and commercial institutions that ask for Sophos.

I used pfSense two years ago, but I was not so happy with our system protection. I have also previously used Cisco ASA appliance. It was a 5505 model, but it failed because of the hardware issues. It was prone to hardware failure, and in one month, we lost both firewalls. It was also not so easy to see traffic with Cisco ASA. I could not easily identify traffic issues. 

I was not at the company when they had a different solution, so I am unsure as to what it was.

Currently, I'm looking for another firewall and I am working on upgrading. We may use an Ignition firewall in the near future.

I've also deployed a couple of different firewalls in the past, including Huawei.

Previously, we used the Fortinet FortiGate switch because of the devices we have. They were limited to maybe 100-200 MB and were slowing down very drastically with Fortinet. 

For many different reasons and because I need to do IP implementation that was not very compatible with our VPN, we switched. Now we have no problem integrating the VPN. 

We switched to this open source solution and so far we are happy with it.

I compared pfSense vs OPNSense. I used to use pfSense. I switched because OPNSense is modern and new. The graphic interface is good. And sometimes pfSense is not stable. Sometimes it breaks the line and stops.

I was previously using pfSense but I switched to OPNsense because it was a newer kernel, which would have worked better with our upgraded hardware.

I have used ClearOS for a long time prior to pfSense.
