Quotes From Members

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

Pros
"I like the firewall features, Snort, and the Intrusion Prevention System (IPS).""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.""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 most valuable features of this solution are the integrations and IPS throughput.""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.""If configured, Firepower provides us with application visibility and control.""One of the nice things about Firepower is that you can set it to discover the environment. If that is happening, then Firepower is learning about every device, software operating system, and application running inside or across your environment. Then, you can leverage the discovery intelligence to get Firepower to select the most appropriate intrusion prevention rules to use for your environment rather than picking one of the base policies that might have 50,000 IPS rules in it, which can put a lot of overhead on your firewall. If you choose the recommendations, as long as you update them regularly, you might be able to get your rule set down to only 1,000 or 1,500, which is a significant reduction in a base rule set. This means that the firewall will give you better performance because there are less rules being checked unnecessarily. That is really useful.""The most valuable feature that Cisco Firepower NGFW provides for us is the Intrusion policy."

"Cisco is head-and-shoulders above all of the competition when it comes to technical support.""What I have used the most and received the most benefit from is the IPsec technology.""The hardware is pretty stable. It's also a very good product performance-wise. Initially, it wasn't mature like a firewall and there were other leaders, but now they have included almost all the features of next-generation security. Basically, it's a good product to work with.""We are able to filter a lot of traffic especially when a lot of the traffic is in layer 7.""It covers everything we need it to without looking to secondary solutions.""One of the main features is that the hardware is extremely reliable.""The solution is very user-friendly and easy to deal with.""Cisco has always been a premium product. There's a lot of other entry-level solutions. This is more robust."

More Cisco IOS Security Pros »

"The initial implementation process is simple.""The graphic user interface is very good and it is user-friendly which makes the product easy-to-use.""The system in general is quite flexible.""The most valuable features are reporting, the Sensei plugin, and firewall capabilities.""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 most valuable features in OPNsense are reporting and visibility.""OPNsense is easy to scale when running on the hardware.""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."

Cons
"On the VPN side, Firepower could be better. It needs more monitoring on VPNs. Right now, it's not that good. You can set up a VPN in Firepower, but you can't monitor it.""Report generation is an area that should be improved.""It would be great if some of the load times were faster.""It's mainly the UI and the management parts that need improvement. The most impactful feature when you're using it is the user interface and the user experience.""Web filtering needs improvement because sometimes the URL is miscategorized.""The change-deployment time can always be improved. Even at 50 seconds, it's longer than some of its competitors. I would challenge Cisco to continue to improve in that area.""The initial setup can be a bit complex for those unfamiliar with the solution.""The intelligence has room for improvement. There are some hackers that we haven't seen before and its ability to detect those types of attacks needs to be improved."

More Cisco Firepower NGFW Firewall Cons »

"The user interface needs to be improved.""The company needs to make its solution more affordable to make it more accessible to larger markets. Otherwise, it's seen as an enterprise-level solution that small or medium-sized organizations can't afford and therefore they won't even look at it.""With respect to user-friendliness, it is a command-line interface and those with such experience will get along just fine, whereas others may struggle.""I would love it if it has a link-by-link feature, integration with Unified Threat Management (UTM), and load balancers. They haven't got any link-by-link feature right now, which can be a very attractive option. This link-by-link feature can also be made available for Cisco's UTM firewalls. The link-by-link feature is available in some of the other firewalls. Currently, integration with UTM is missing. Cisco IOS Security also doesn't have the load balancers and a few things that need to be done to get a good UTM firewall. Normally, other firewalls have UTM. As a next-generation firewall, it's good, but as a UTM, it has to do some work.""The configuration should be easier in the solution.""I think they should bring back remote VPN for users.""The pricing is the only con for this product.""There could be a bit more functions on offer that could make it easier to use."

More Cisco IOS Security Cons »

"The interface isn't so friendly user. But we have some technicians here who are quite confident with this tool. OPNSense could maybe add sets of rules so it's simpler to manage different groups with particular needs.""The solution could be more secure.""The ability to set the VPN IP address would be a welcome addition.""There are issues with stability and reliability.""The logging could improve in OPNsense.""The solution would not be suitable for anything large-scale.""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."

Pricing and Cost Advice
"There are additional implementation and validation costs.""Pricing is the same as other competitors. It is comparable. The licensing has gotten better. It has been easier with Smart Licensing.""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 are fighting against other competitors for customers, whether it is a small or big business, we feel very comfortable with the price that Firepower has today.""The price for Firepower is more expensive than FortiGate. The licensing is very complex. We usually ask for help from Solutel because of its complexity. I have a Cisco account where I can download the VPN client, then connect. Instead, I create an issue with Solutel, then Solutel solves the case.""Its pricing is good and competitive. There is a maintenance cost. It includes SecureX that makes it cost-effective as compared to the other solutions where you have to pay for XDR and SOAR capabilities.""This product requires licenses for advanced features including Snort, IPS, and malware detection.""I know that licensing for some of the advanced solutions, like Intrusion Prevention and Secure Malware Analytics, are nominal costs."

More Cisco Firepower NGFW Firewall Pricing and Cost Advice »

"Price is certainly something that the IOS technology has fallen behind the competition on.""It is an expensive solution.""The price of the solution should be cheaper, and the license is purchase annually.""The pricing is okay. It is competitive. It costs more when you need get more features.""It is necessary to pay for a license in order to use the solution. It is on a yearly basis and the price is high.""Palo Alto networks are more expensive than this solution and this is why you will see more products like this one in Mexico."

More Cisco IOS Security 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.""OPNsense is an open-source solution and it is free to use.""OPNsense is a well known open-source tool.""OPNsense is open source software so at this time it is free for us to use.""As an appliance, it's in the medium price range.""The solution is not expensive."
