We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The most valuable feature is the access control list (ACL).""It's got the capabilities of amassing a lot of throughput with remote access and VPNs.""We have not had to deal with stability issues.""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.""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 solution offers very easy configurations.""The Adversity Malware Protection (AMP) feature is the most valuable. It is also very easy to use. Every technical user can operate this solution without any difficulty. The dashboard of Cisco Firepower has every tool that a security operator needs. You can find every resource that you need to operate through this dashboard.""The dashboard is the most important thing. It provides good visibility and makes management easy. Firepower also provides us with good application visibility and control."

"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 initial implementation process is simple.""It has an open license. It works very well, and there is an update every month.""The most valuable features are reporting, the Sensei plugin, and firewall capabilities.""The IDS and IPS features are valuable. From the usability perspective, there is a lot of good documentation. As IT professionals, we found it very easy to configure the firewall. It was easy to configure and use.""OPNsense is highly stable."

Cons
"Report generation is an area that should be improved.""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 was a bit complex. It wasn't a major challenge, but due to our requirements and network, it was not very straightforward but still easy enough.""Licensing is complex, and I'd like it to be simplified. This is an area for improvement.""The performance should be improved.""A major area of improvement would be to have more functionality in public clouds, especially in terms of simplifying it. The high availability doesn't work right now because of the limitations in the cloud.""We only have an issue with time sync with Cisco ASA and NTP. If the time is out of sync, it will be a disaster for the failover.""One of the few things that are brought up is that for the overall management, it would be great to have a cloud instance of that. And not only just a cloud instance, but one of the areas that we've looked at is using an HA type of cloud. To have the ability to have a device file within a cloud. If we had an issue with one, the other one would pick up automatically."

"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 support for OPNsense is good because we have documents available on the internet. The support could improve a little.""We did not like the fact that you have to configure everything with the graphic user interface. We have used other firewalls, such as FortiGate, that you can configure via code. OPNsense is not easy to integrate. When you are deploying via GitHub or another source repository, this is not possible. That's one thing we didn't like much.""I would like to see better SD-WAN performance.""The interface needs to be simplified. It is not user-friendly.""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 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.""Its interface should be a little bit better."

Pricing and Cost Advice
  • "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."
  • "The price is comparable."
  • "It definitely competes with the other vendors in the market."
  • More Cisco Firepower NGFW Firewall 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."
  • "The solution is not expensive."
  • "As an appliance, it's in the medium price range."
  • "Its pricing is unbeatable in comparison to other firewalls. You can have a small instance that could be €80 a month with the hardware underneath. Azure Firewall and FortiGate are out of the question at this price. If you are on a public cloud, you need the underlying infrastructure. Other than that, there is no additional cost. If you have it on-prem, you have to buy the server or the appliance. The hardware cost is replaced with the infrastructure cost in the cloud. You also have costs for the public IPs and underlying VMs, but that's not related to OPNsense. It would be the same for a FortiGate deployment on Azure. You need a FortiGate license, and you need the underlying infrastructure that scales up depending on your needs."
  • "It is open source and free."

    Overview

    Cisco Firepower Next-Generation Firewall (NGFW) is a firewall that provides capabilities beyond those of a standard firewall and delivers comprehensive, unified policy management of firewall functions, application control, threat prevention, and advanced malware protection from the network to the endpoint.

    Cisco NGFW Firewalls include advanced threat defense capabilities to meet diverse needs, from small offices to high-performance data centers and service providers, and are deployed in leading private and public clouds. Available in a wide range of models, Cisco NGFW can be deployed as a physical or virtual appliance. Cisco NGFW firewalls are also available with clustering for increased performance, high availability configurations, and more.

    Key Features of Cisco NGFW Firewalls

    • Breach prevention and advanced security: Prevent attacks before they get inside. Cisco provides its firewalls with the latest intelligence to stop emerging threats and employs filtering to enforce policies on hundreds of millions of URLs. Cisco NGFW offers built-in sandboxing and advanced malware protection that continuously analyzes file behavior to quickly detect and eliminate threats.

    • Comprehensive network visibility: Constantly monitor your network so you can rapidly spot and stop bad behavior. Cisco NGFW provides a holistic view of all activity and provides a clear picture of threat activity across users, hosts, networks, and devices, as well as information on threats and website, application, and VM activities.

    • Flexible management and deployment options: Centrally deploy, customize, and manage all your appliances.

    • Fast detection: Detect threats in seconds and detect the presence of a successful breach within hours or minutes. Cisco NGFW allows you to deploy consistent policy that's easy to maintain, with automatic enforcement across all the different parts of your organization.

    • Automation and product integrations: Seamlessly integrate with Cisco tools and automatically share threat information, event data, policy, and contextual information with email, web, endpoint, and network security tools. Cisco NGFW automates security tasks like impact assessment, policy management and tuning, and user identification.

    Reviews from Real Users

    Cisco NGFW stands out among its competitors for a number of reasons. Two major ones are its extensive discovery abilities that enable you to constantly see what is happening on your network and take action when necessary, and the high level of protection it provides.

    Mike B., a director of IT security at a wellness & fitness company, writes, "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."

    Zhulien K., the lead network security engineer at TechnoCore LTD, notes, " The most valuable feature that Cisco Firepower NGFW provides for us is the Intrusion policy. Again, with that being said, I cannot shy away from giving kudos to all of the other features such as AVC (Application Visibility and Control), SSL Decryption, Identity policy, Correlation policy, REST API, and more. All of the features that are incorporated in the Cisco Firepower NGFW are awesome and easy to configure if you know what you are doing. Things almost always work, unless you hit a bug, which is fixed with a simple software update. "

    OPNsense is a user-friendly, fast-track, open-source FreeBSD-based firewall and routing platform. This software offers features that are generally available from costly commercial firewalls, with the added benefit of open and verifiable sources.

    Reviews from Real Users

    OPNsense is a favorite security solution among reviewers for a number of reasons. Two of those reasons include the user-friendliness of the solution, which makes it easy to use, and its ability to easily scale.

    For many, a user-friendly solution is essential. FiorindoDi A., a system administration specialist at a tech vendor, says, "The graphic user interface is very good and it is user-friendly, which makes the product easy-to-use."

    Peerspot reviewers speak of the scalability of the solution. For example, an anonymous cloud and infrastructure manager at a venture capital and private equity firm reviewer notes, "OPNsense is easy to scale when running on the hardware."
