Quotes From Members

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

Pros
"I have access to the web version of Cisco Talos to see the reputation of IP addresses. I find this very helpful. It provides important information for my company to obtain the reputation of IP addresses. The information in Talos is quite complete.""The integration of network and workload micro-segmentation helps a lot to provide unified segmentation policies across east-west and north-south traffic. One concrete example is with Cisco ACI for the data center. Not only are we doing what is called a service graph on the ACI to make sure that we can filter traffic east-west between two endpoints in the same network, but when we go north-south or east-west, we can then leverage what we have on the network with SGTs on Cisco ISE. Once you build your matrix, it is very easy to filter in and out on east-west or north-south traffic.""The most important feature is the intensive way you can troubleshoot Cisco Firepower Firewalls. You can go to the bit level to see why traffic is not handled in the correct way, and the majority of the time it's a networking issue and not a firewall issue. You can solve any problem without Cisco TAC help, because you can go very deeply under the hood to find out how traffic is flowing and whether it is not flowing as expected. That is something I have never seen with other brands.""It's got the capabilities of amassing a lot of throughput with remote access and VPNs.""It is one of the fastest solutions, if not the fastest, in the security technology space. This gives us peace of mind knowing that as soon as a new attack comes online that we will be protected in short order. From that perspective, no one really comes close now to Firepower, which is hugely valuable to us from an upcoming new attack prevention perspective.""We get the Security Intelligence Feeds refreshed every hour from Talos, which from my understanding is that they're the largest intelligence Security Intelligence Group outside of the government.""Another benefit has been user integration. We try to integrate our policies so that we can create policies based on active users. We can create policies based on who is accessing a resource instead of just IP addresses and ports.""Firepower has been used for quite a few enterprise clients. Most of our clients are Fortune 500 and Firepower is used to improve their end to end firewall functionality."

"The stability of the solution is good. We haven't faced any issues at all while using the product.""The most valuable feature is that its IPsec works perfectly.""The most valuable feature is the WAN optimization.""The solution offers good documentation.""The most valuable features we have found to be the VPN, ease of use, and overall simplicity.""The most valuable feature is geofencing, where we can block all access from all non-domestic locations.""The thing that I like the most is that they're very willing to work with us to resolve issues that they haven't taken care of before in their product.""Fortinet FortiGate-VM is easy to use."

"OPNsense is easy to scale when running on the hardware.""I have found the solution has some great features overall, such as guest access capabilities, dashboards, and ease of use. There is plenty of documentation and support and it has the plugins that I needed.""The solution is good for a basic firewall for a small business or for home use.""The most valuable features in OPNsense are reporting and visibility.""The interface and the dashboard are the most valuable features of this solution.""The VPN server feature is the most valuable. It is integrated with Radius and AAA for doing accounting and authentication. Insight view is also an important feature for me at this time. It allows me to assess our network traffic. I also like the firewall feature. The BSD kernel has a packet filter. It is one of the most solid frameworks for firewalls. Its user interface is one of the best interfaces I have used.""The initial implementation process is simple.""The most valuable features are reporting, the Sensei plugin, and firewall capabilities."

Cons
"We cannot have virtual domains, which we can create with FortiGate. This is something they should add in the future. Additionally, there is a connection limit and the FMC could improve.""The configuration in Firepower Management Center is very slow. Deployment takes two to three minutes. You spend a lot of time on modifications. Whereas, in FortiGate, you press a button, and it takes one second.""I would like it to have faster deployment times. A typical deployment could take two to three minutes. Sometimes, it depends on the situation. It is better than it was in the past, but it could always use improvement.""There is limited data storage on the appliance itself. So, you need to ship it out elsewhere in order for you to store it. The only point of consideration is around that area, basically limited storage on the machine and appliance. Consider logging it elsewhere or pushing it out to a SIEM to get better controls and manipulation over the data to generate additional metrics and visibility.""The solution could offer better control that would allow the ability to restrictions certain features from a website.""The central management tool is not comfortable to use. You need to have a specific skill set. This is an important improvement for management because I would like to log into Firepower, see the dashboard, and generate a real-time report, then I question my team.""One issue with Firepower Management Center is deployment time. It takes seven to 10 minutes and that's a long time for deployment. In that amount of time, management or someone else can ask me to change something or to provide permissions, but during that time, doing so is not possible. It's a drawback with Cisco. Other vendors, like Palo Alto or Fortinet do not have this deployment time issue.""The performance should be improved."

"The solution is fairly complex.""We are experiencing a failed login issue. There should also be improvements in functionalities we store to enhance our services.""The user interface could be improved.""We haven't attempted to scale the solution just yet. If we want to scale this solution we may have to look at other models. With certain requirements, we probably wouldn't be able to scale it so well as it is right now.""Compatibility and integration with other products or vendors such as Cisco SD-WAN products need improvement.""Technical support could be improved.""There should be more options to use lower-end models in a high availability configuration.""There should be a bit more automation."

More Fortinet FortiGate-VM Cons »

"There should be more technical documentation.""While they do have paid options that actually gives better features, for most of the clients, if they tend to take a paid option will instead opt for Fortinet.""The solution could be more secure.""There are issues with stability and reliability.""The ability to set the VPN IP address would be a welcome addition.""The logging could improve in OPNsense.""The solution would not be suitable for anything large-scale.""I would like to see better SD-WAN performance."

Pricing and Cost Advice
"I am happy with the product in general, including the pricing.""For me, personally, as an individual, Cisco Firepower NGFW Firewall is expensive.""It definitely competes with the other vendors in the market.""The solution was chosen because of its price compared to other similar solutions.""The price of Firepower is not bad compared to other products.""Cisco is not for a small mom-and-pop shop because of the cost, but if you're in a regulated industry where a breach could cost you a million dollars, it's a bargain.""When we purchased the firewall, we had to take the security license for IPS, malware protection, and VPN. If we are using high availability, we have to take a license for that. We also have to pay for hardware support and technical support. Its licensing is on a yearly basis.""There are additional implementation and validation costs."

More Cisco Firepower NGFW Firewall Pricing and Cost Advice »

"The price could be lower.""With Fortinet FortiGate-VM you can bring your own licensing, or it can be paid on a yearly basis.""This solution is very expensive.""Our license is yearly, but we're thinking of going monthly. I think it's somewhere around 100,000 for VM04. Nowadays, everyone wants to be a hacker, so we believe in security. That's why we also have third-party people that we involve to make sure that we're secure. I don't think the costs are too bad. You still want to get advice from people who worked in security for many years, so you add a third party. The third party also said they would give their share like 100K, or 200K or something like that, so I don't think it's too expensive for security. I think it just adds more trust.""It's a mid-ranged product.""Of all the firewalls that we compared, FortiGate is the cheapest and most affordable, so we are satisfied with the pricing.""There is an annual license required to use the solution.""There are yearly or monthly licenses which you can choose from."

More Fortinet FortiGate-VM Pricing and Cost Advice »

"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source.""As an appliance, it's in the medium price range.""OPNsense is a well known open-source tool.""The solution is not expensive.""OPNsense is an open-source solution and it is free to use.""OPNsense is open source software so at this time it is free for us to use."
