Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"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.""There are no issues that we are aware of. It does its job silently in the background.""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.""A good intrusion prevention system and filtering.""Provides good integrations and reporting.""Web filtering is a big improvement for us. The previous version we used, the AC520, did not have that feature included. It was not very easy for us, especially because the environment had to be isolated and we needed to get updates from outside, such as Windows patches. That feature has really helped us when we are going outside to pull those patches.""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.""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."

"The configuration was kind of straightforward from the command line and also from the ASDM. It was very easy to manage by using their software in Java.""It's a flexible solution and is well-known in the community.""On the network side, where you create your rules for allowing traffic — what can come inside and what can go out — that works perfectly, if you know what you want to achieve. It protects you.""The remote VPN and IPsec VPN or site-to-site VPN features are valuable. The clustering feature is also valuable. We have two ISP links. Whenever there is a failover, users don't even get to know. The transition is very smooth, and the users don't notice any latency. So, remote VPN, site-to-site VPN, and failover are three very powerful features of Cisco ASA.""Technical support services are excellent.""The best features are stability and scalability.""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.""I have found the stability of this solution really good. This is why I use it."

"The most valuable features in OPNsense are reporting and visibility.""OPNsense is easy to scale when running on the hardware.""We have found pretty much all the features of the solution to be valuable.""The initial implementation process is simple.""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 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 system in general is quite flexible.""The graphic user interface is very good and it is user-friendly which makes the product easy-to-use."

Cons
"In a future release, it would be ideal if they could offer an open interface to other security products so that we could easily connect to our own open industry standard.""The price and SD-WAN capabilities are the areas that need improvement.""Implementations require the use of a console. It would help if the console was embedded.""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 solution could offer better control that would allow the ability to restrictions certain features from a website.""This product is managed using the Firepower Management Center (FMC), but it would be better if it also supported the command-line interface (CLI).""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.""I would like to see improvement when you create policies on Snort 3 IPS on Cisco Firepower. On Snort 2, it was more like a UI page where you had some multiple choices where you could tweak your config. On Snort 3, the idea is more to build some rules on the text file or JSON file, then push it. So, I would like to see a lot of improvements here."

More Cisco Firepower NGFW Firewall Cons →

"They need a user-friendly interface that we could easily configure.""On firewall features, Fortinet is better. Cisco needs to become more competitive and add more features or meet Fortinet's offering.""Cisco ASA Firewall could improve by adding more advanced features such as web filtering, which is available in the next-generation firewalls. However, the Cisco ASA Firewall I am using could be old and these features have been updated.""It is expensive.""Other products are becoming easier to access and configure. They are providing UI interfaces to configure, take backup, synchronize redundant machines, and so on. It is very easy to take backup and upgrade the images in those products. Cisco ASA should have such features. If one redundant machine is getting upgraded, the technology and support should be there to upgrade other redundant machines. In a single window, we should be able to do more in terms of backups, restores, and upgrades.""We have more than one Cisco firewall and it is difficult for me to integrate both on the single UI.""We don't have any serious problems. The firewall models that we have are quite legacy, and they have slower performance. We are currently investigating the possibility of migrating to next-generation firewalls.""This is an older product and has reached end-of-life."

More Cisco ASA Firewall 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 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.""The ability to set the VPN IP address would be a welcome addition.""The solution could be more secure.""The solution would not be suitable for anything large-scale.""I would like to see better SD-WAN performance.""The interface needs to be simplified. It is not user-friendly.""There are issues with stability and reliability."

Pricing and Cost Advice
  • "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."
  • "For me, personally, as an individual, Cisco Firepower NGFW Firewall is expensive."
  • "The price of Firepower is not bad compared to other products."
  • "The solution was chosen because of its price compared to other similar solutions."
  • More Cisco Firepower NGFW Firewall Pricing and Cost Advice →

  • "In terms of costs, other solutions are more expensive than Cisco. Palo Alto is more expensive than Cisco."
  • "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."
  • "Cisco is expensive, but you do get benefits for the price."
  • "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."
  • "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."
  • "Always consider what you might need to reduce your wasted time and invest it in other solutions."
  • "Cisco is considered to be an expensive solution."
  • More Cisco ASA Firewall 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."
