Pricing and Cost Advice
  • "I had to pay for the license for the firewall, but it is guaranteed to have updates. I expect a good service for it. It was about €1000 for a year, and there was no additional cost."
  • "It is more expensive than Sophos. Fortinet is overall more expensive than Sophos. The small range of Fortinet, such as 60F and 80F, is more expensive than the small range of Sophos. Sophos is cheaper. In addition, if you jump from 80F Series to 100F Series, the price doubles."
  • "The license is yearly. We pay for the top end. It's called 360."
  • "Here in Brazil, we're going through difficult economic times and the tax on the dollar is high. All the solutions from minor competitors are growing in the market. The prices have come more competitive."
  • "Licensing for Fortinet FortiGate is on a yearly basis. Pricing for it is a bit high. It could be cheaper."
  • "The licensing scheme of Fortinet is better than Cisco. It is more logical."
  • "The solution requires a license annually, it is not a user license, you can have as many users as your want. I must renew the license regularly per device."
  • "It was probably about $2,500 per firewall. It was all included. It included support, services, threat management software, and 24/7 FortiCare on it. Cisco products are more expensive."

    • More Fortinet FortiGate Pricing and Cost Advice →

  • "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."
  • "The price of OPNsense is good."
  • "I'm using the free version of OPNsense. I didn't check the pricing for the solution because I still need to test it before getting the approval to purchase OPNsense, and it isn't easy to get approval from the higher-ups."
  • "It's a free solution."
  • "It's not expensive."

    Overview

    Fortinet FortiGate is an innovative line of firewalls that aim to protect organizations from all types of web-based network threats. They come in a wide variety of product types. Fortinet FortiGate’s solutions are available in a large range of sizes and form factors and are key components of the Fortinet Security Fabric, which enables immediate, intelligent defense against known and new threats throughout the entire network.

    Fortinet FortiGate provides users with next-generation firewall solutions that provide proven protection with unmatched performance across the network, from internal segments to data centers to cloud environments. You can protect every part of your network without exception. Additionally, your protections can be managed from a single central location. This ensures that the task of protecting your network is infinitely easier to accomplish.

    Benefits of Fortinet FortiGate

    Some of the benefits of using Fortinet FortiGate include:

    • The ability to manage your firewalls from a centralized automated control console. Fortinet FortiGate’s FortiManager enables administrators to exercise control of their firewalls in a streamlined manner. Administrators have full visibility and control over their system from a single location. It utilizes automation that collects information in real time, which greatly simplifies and reduces the cost of running various types of workflows. Administrators can free up resources by automating the most basic tasks.
    • The ability to produce uniform, appropriate, and coordinated responses to threats across networks. Fortinet FortiGate’s FortiGuard feature generates system protections in near real time. This allows administrators to address threats to the system with custom-made solutions that can be uniformly enforced.
    • The ability to scale up your security to fit your changing security needs. Fortinet FortiGate’s design allows users to accelerate the transfer of data between users and escalate the number of users that are covered without compromising security of performance. This means that users can grow their networks and continue to collaborate without worrying about the system slowing down or coming under attack.

    Reviews from Real Users

    Fortinet FortiGate’s firewall solutions are cutting edge. They stand out from competitors for a number of reasons. Two major ones are the robustness and power of their firewalls. Fortinet FortiGate’s firewall provides users with many valuable features that allow them to maximize what they can do with the solution. These firewalls enable users to use a single piece of software to accomplish tasks that often require the use of multiple pieces of software.

    PeerSpot user Eric S., a Solutions Engineer and Consultant at a tech-services company, notes the robustness of this solution when he writes, "One of the nice things about FortiGate is that it can be deployed on the cloud or on-premises. You can actually do both. That's the biggest reason why I stick with this solution as opposed to something like Cisco Meraki. Another nice thing is that I can log directly into a FortiGate or get to it through their FortiCloud access products. They're pretty reliable and consistent. One of the reasons why I started using the product was their single pane of management. I can deploy their line of firewalls in conjunction with their switching and access points, and I can manage the entire network from one interface.”

    PeerSpot user Jim M., a network admin at Penobscot Valley Hospital, notes the power of Fortinet FortiGate’s security software when he writes, "It does a lot for you for intrusion protection and as an antivirus. The threat management bundle is worth the money. You don't need another company to monitor your web traffic for you. You can do everything yourself on the firewall. You restrict your own black list for people on the firewall.”

    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.

    • 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."
