Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"I have integrated it for incidence response. If there is a security event, the Cisco firewall will automatically block the traffic, which is valuable.""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.""There are no issues that we are aware of. It does its job silently in the background.""The most valuable feature is the Intrusion Prevention System.""I have experience with URL filtering, and it is very good for URL filtering. You can filter URLs based on the categories, and it does a good job. It can also do deep packet inspection.""The feature set is fine and is rarely a problem.""The most valuable features of this solution are the integrations and IPS throughput.""The most important features are the intrusion prevention engine and the application visibility and control. The Snort feature in Firepower is also valuable."

"It has been stable so far.""The only firewall able to monitor traffic from a CCTV network. Can detect unauthorized devices plugged into the network, which standard firewalls can't do."

More Hillstone T-Series Pros →

"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.""The most valuable features are reporting, the Sensei plugin, and firewall capabilities.""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.""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.""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 system in general is quite flexible."

Cons
"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.""The solution could offer better control that would allow the ability to restrictions certain features from a website.""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.""Cisco Firepower NGFW Firewall can be more secure.""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.""Web filtering needs improvement because sometimes the URL is miscategorized.""The application detection feature of this solution could be improved as well as its integration with other solutions.""They need a VTI. I know it's going to be available in the next software version, which is the 6.7 version. However, the problem with that is that the 6.7 is going to deprecate all the older IKEv1 deployment tunnels. Therefore, the problem is that we have a lot of customers which are using older encryptions. If I do that, update it, it's not going to work for me."

More Cisco Firepower NGFW Firewall Cons →

"Licensing is not cheap.""They have a very good technical support team, but I think there are some communication issues due to language differences."

More Hillstone T-Series Cons →

"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.""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.""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.""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.""The logging could improve in OPNsense."

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."

  • "We got a much cheaper price than that provided by Fortinet right now."
  • More Hillstone T-Series 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."

    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. "

    Hillstone’s T-Series intelligent Next-Generation Firewall (iNGFW) uses three key technologies to detect advanced attacks and provide continuous threat defense for today’s networks. First, it uses statistical clustering to detect unknown malware, leveraging the patented Hillstone Advanced Threat Detection engine (ATD). Second, it uses behavioral analytics to detect anomalous network behavior, which is based on the Hillstone Abnormal Behavior Detection engine (ABD). Finally, it leverages the Hillstone threat correlation analysis engine to correlate threat events detected by disparate engines – including ATD, ABD, Sandbox and other traditional signature-based threat detection technologies – along with context information to identify advanced threats.

    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. The firewall provides users, developers, and organizations with an advantageous environment through transparency. The development of this project is driven by a strong focus on security and code quality.

    The solution offers a variety of components, such as:

    • Weekly security updates. These updates provide the user with the ability to reach new emerging threats in a timely manner through small increments.

    • Two major releases every year. These yearly releases are on a fixed release cycle and provide organizations with the ability to plan ahead of an upcoming upgrade.

    • A roadmap of instructions. Each major release provides a guide and a set of clear goals.

    A team of professionals developed OPNsense. Other professional and experienced software architects, engineers, and developers are encouraged to join in the development of the solution to make it as successful as possible. OPNsense offers a variety of rich features with each release. Each upgrade is based on FreeBSD for continual, long-term support and utilizes a freshly advanced MVC framework based on Phalcon. OPNsense is committed to helping businesses, school networks, remote offices, hotels, and other markets in keeping their data protected.

    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."
