Quotes From Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
"Everything is all documented in the file or in the command line script that gets uploaded to the device. It gives us great visibility.""The user interface is easy to navigate.""It is very stable compared to other firewall products.""The management aspect of the product is very straightforward.""The best features are stability and scalability.""Unfortunately in Cisco, only the hardware was good.""The most valuable feature must be AnyConnect. We have quite a few customers who use it. It is easy to use and the stablest thing that we have. We have experienced some issues on all our VPN clients, but AnyConnect has been the stablest one.""The traffic inspection and the Firepower engine are the most valuable features. It gives you full details, application details, traffic monitoring, and the threats. It gives you all the containers the user is using, especially at the application level. The solution also provides application visibility and control."

"The most valuable features in OPNsense are reporting and visibility.""The interface and the dashboard are the most valuable features of this solution.""The solution is good for a basic firewall for a small business or for home use.""The graphic user interface is very good and it is user-friendly which makes the product easy-to-use.""The initial setup is easy. It only takes 15-30 minutes to deploy.""The feature I find most valuable, is that the program helped me to realize all the requested functionality that was needed.""I find the solution to be user-friendly. It has a lot of reports and easy settings.""We can open a new VPN connection easily. It's much easier than with Fortinet in our experience."

More OPNsense Pros »

"The initial setup was simple and fast.""The initial setup is easy.""Great extensibility of the platform.""Good basic firewall features.""The solution is very robust.""The most valuable features are the VPN and the capture photo.""The scalability is very good, where you can do an HA configuration and then bring in another box, if necessary.""This solution has increased the level of security, given us more control, provided a deep insight into network traffic, and is a great VPN solution."

Cons
"I would say that in inexperienced hands, the interface can be kind of overwhelming. There are just a lot of options. Too much, if you don't know what you are looking for or trying to do.""The annual subscription cost is a bit high. They should try to make it comparable to other offerings. We have a number of Chinese products here in Pakistan, which are already, very cheap and have less annual maintenance costs compared to Cisco.""They need a user-friendly interface that we could easily configure.""It would be nice if you didn't have to configure using a command-line interface. It's a bit technical that way.""You shouldn't have to use the ASDM to help manage the client.""In NGFW, Cisco should be aligned with the new technology and inspection intelligence because Cisco is far behind in this pipeline.""One of the problems that we have had is the solution requires Java to work. This has caused some problems with the application visibility and control. When the Java works, it is good, but Java wasn't a good choice. I don't like the Java implementation. It can be difficult to work with sometimes.""Security generally requires integration with many devices, and the management side of that process could be enhanced somewhat. It would help if there was a clear view of the integrations and what the easiest way to do them is."

More Cisco ASA Firewall Cons »

"There are issues with stability and reliability.""There should be more technical documentation.""The solution would not be suitable for anything large-scale.""The ability to set the VPN IP address would be a welcome addition.""On the customer-side, because I'm a small business, I need a cheaper or free solution option.""OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server."

More OPNsense Cons »

"ClamAV AntiVirus can cause some crashes. That service should be improved.""As an open-source solution, there are so many loopholes happening within the product. By design, no one is taking ownership of it, and that is worrisome to me.""User interface is a little clumsy.""Layer 7 advanced firewall features are not included in the solution.""The solution requires a lot of administration.""If a user doesn't have a large amount of experience in Linux systems, they will have problems using this solution. Users need to be highly skilled in troubleshooting competency. Users who do not have such skills will find the product difficult to use.""I would like to see different graphs available in the reporting.""We would like to see ready-made profiles to cover most users' needs."

Pricing and Cost Advice
"We pay about $200 yearly and we have two firewalls.""It's very competitive with other products.""Cisco is considered to be an expensive solution.""Always consider what you might need to reduce your wasted time and invest it in other solutions.""The licensing is a bit off because the physical firewall is cheaper than the virtual one. We only have the physical ones as they are cheaper than the virtual ones. We only use the physical firewalls because of the price difference.""There is room for improvement in the pricing when compared to the market. Although, when you compare the benefits of support from Cisco, you can adjust the value and it becomes comparable, because you usually need very good support. So you gain value there with this device.""When it comes to Cisco, the price of everything is higher. Cisco firewalls are expensive, but we get support from Cisco, and that support is very active.""It's a brilliant firewall, and the fact that it comes with a perpetual license really does go far in terms of helping the organization in not having to deal with those costs on an annual basis. That is a pain point when it comes to services like the ones we have on Fortigate. That's where we really give Cisco firewalls the thumbs up."

"OPNsense is a well known open-source tool.""OPNsense is open source software so at this time it is free for us to use.""There are no licensing costs for OPNsence.""It costs about $1000.""We are not paying any licensing fees. OPNsense is completely free for us."

More OPNsense Pricing and Cost Advice »

"It is an open source firewall.""This solution provides enterprise-level features at a fraction of the cost of an enterprise firewall.""All costs are low compared to other solutions. The hardware is stable and cheap.""There is no licensing fee except for the enterprise support, if you want it.""This solution was about $150,000 cheaper than the closest competitor over a three year period."
