Quotes From Members

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

Pros
"The IPS, as well as the malware features, are the two things that we use the most and they're very valuable.""The protection and security features, like URL filtering, the inspection, and the IPS feature, are also very valuable for us. We don't have IT staff at most of the sites so for us it's important to have a robust firewall at those sites""We can easily track unauthorized users and see where traffic is going.""With the FMC and the FirePOWERs, the ability to quickly replace a piece of hardware without having to have a network outage is useful. Also, the ability to replace a piece of equipment and deploy the config that the previous piece of equipment had is pretty useful.""They wanted to leverage something which is equivalent that can give them the next gen features like application awareness and intrusion protection. So that is a major reason they were looking forward to this. The original ASA firewall did not have these features. This was the major reason the customer moved on to Cisco Firepower Threat Defense (FTD). Now they can go ahead and leverage those functionalities.""The Firepower+ISE+AMP for endpoint integration is something that really stands it out with other vendor solutions. They have something called pxGrid and i think it is already endorsed by IETF. This allows all devices on the network to communicate.""Being able to determine our active users vs inactive users has led us to increased productivity through visibility. Also, if an issue was happening with our throughput, then we wouldn't know without research. Now, notifications are more proactively happening.""One of the most valuable features is the AMP. It's very good and very reliable when it comes to malicious activities, websites, and viruses."

"FortiGate is a nice and very good product.""The product is quite user-friendly so we didn't have a lot of issues that needed to be addressed.""The standard features, including the filtering, are quite good. All the basic features are pretty useful for us.""The most valuable features are site-to-site connections and UTM.""The stability of the solution is good. We haven't faced any issues at all while using the product.""The most valuables features are the ease of use and deployment.""In terms of administration, it's perfect.""The most valuable features are the web proxy for protection and web gateway for deployment."

"The graphic user interface is very good and it is user-friendly which makes the product easy-to-use.""The solution is good for a basic firewall for a small business or for home use.""The interface and the dashboard are the most valuable features of this solution.""The most valuable features in OPNsense are reporting and visibility.""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 most valuable features are reporting, the Sensei plugin, and firewall capabilities.""We have found pretty much all the features of the solution to be valuable.""OPNsense is easy to scale when running on the hardware."

Cons
"For the new line of FTDs, the performance could be improved. We sometimes have issues with the 41 series, depending what we activate. If we activate too many intrusion policies, it affects the CPU.""The user interface for the Firepower management console is a little bit different from traditional Cisco management tools. If you look at products we already use, like Cisco Prime or other products that are cloud-based, they have a more modern user interface for managing the products. For Firepower, the user interface is not very user-friendly. It's a little bit confusing sometimes.""We would like to see improvement in recovery. If there is an issue that forces us to do recovery, we have to restart or reboot. In addition, sometimes we have downtime during the maintenance windows. If Cisco could enhance this, so that upgrades would not necessarily require downtime, that would be helpful.""We had an event recently where we had inbound traffic for SIP and we experienced an attack against our SIP endpoint, such that they were able to successfully make calls out... Both CTR, which is gathering data from multiple solutions that the vendor provides, as well as the FMC events connection, did not show any of those connections because there was not a NAT inbound which said either allow it or deny it.""I was just trying to learn how this product actually operates and one thing that I see from internal processing is it does fire-walling and then sends it to the IPS model and any other model that needs to be performed. For example, content checking or filtering will be done in a field processing manner. That is something that causes delays in the network, from a security perspective. That is something that can be improved upon. Palo Alto already has implemented this as a pilot passed processing. So they put the same stream of data across multiple modules at the same time and see if it is giving a positive result by using an XR function. So, something similar can be done in the Cisco Firepower. Instead of single processing or in a sequential manner, they can do something similar to pile processing. Internal function that is something that they can improve upon.""The product line does not address the SMB market as it is supposed to do. Cisco already has an on-premises sandbox solution.""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 feature I would like to see, that Firepower doesn't have, is email security. Perhaps in the future, Cisco will integrate Cisco Umbrella with Firepower. I don't see why we should have to pay for two separate products when both could be integrated in one box."

"FortiGate should be more customer friendly and budgeted better.""Customization needs improvement.""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.""When new versions are deployed they tend to be a little buggy, so they should be more fully tested before release.""The user interface needs to be improved.""In the next release, we would like to see full integration with VMware NSX virtualized networks.""The interface needs to be updated and simplified.""In the next release, I would like to see integration capability with SIEM tools, such as QRadar, and LogRhythm."

More Fortinet FortiGate-VM Cons »

"The ability to set the VPN IP address would be a welcome addition.""The solution would not be suitable for anything large-scale.""There should be more technical documentation.""There are issues with stability and reliability.""The only thing that I would like to see improved is the Insight or the NetFlow analysis part. It would be good to have the possibility to dig down on the Insight platform. Right now, we can easily do only a few analyses. If this page becomes more powerful, it surely will be a well-adopted platform.""I would like to see better SD-WAN performance.""The solution could be more secure.""The interface needs to be simplified. It is not user-friendly."

Pricing and Cost Advice
"Cisco's pricing is high, at times, for what they provide.""The one-time cost is affordable, but the maintenance cost and the Smart Net costs need to be reduced. They're too high.""We normally license on a yearly basis. The hardware procurement cost should be considered. If you're virtual maybe that cost is eradicated and just the licensing cost is applied. If you have hardware the cost must be covered by you. All the shipping charges will be paid by you also. I don't thing there are any other hidden charges though.""Cisco pricing is premium. However, they gave us a 50 to 60 percent discount.""There are additional implementation and validation costs.""Cisco, as we all know, is expensive, but for the money you are paying, you know that you are also getting top-notch documentation as well as support if needed.""This product requires licenses for advanced features including Snort, IPS, and malware detection.""This product is expensive."

More Cisco Firepower NGFW Firewall Pricing and Cost Advice »

"The price of this product is great compared to others.""This solution is very expensive.""The price is similar to Symantec Endpoint, but it's more expensive than Forcepoint solutions. Fortinet is better than Forcepoint.""There is a benefit in terms of the cost of using this solution because the price is very good.""It's not a cheap solution but it comes with its benefits.""Of all the firewalls that we compared, FortiGate is the cheapest and most affordable, so we are satisfied with the pricing.""There is no additional cost. Once you get the licensing fee, you're good.""There should be a reduction in the setup price and licensing costs."

More Fortinet FortiGate-VM Pricing and Cost Advice »

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