I would rate their support for FortiGate a nine out of ten.
They offer very accurate solutions.
The quick resolution of issues with Fortinet FortiGate is due to the support of the company and the fact that the equipment is easy to work with.
I must study the best version to install to avoid previously found bugs.
In some cases, you need to come prepared because the people there work by the book and ask for particular things. If you don't have them, you cannot proceed, but if you know what they need, after some time, it's pretty easy to get support or whatever you need.
FortiGate offers good support.
I mainly rely on community support since the solution is open source.
 

Scalability Issues

Sentiment score
7.3
Fortinet FortiGate scales well for diverse enterprises, though planning and licensing are crucial to avoid hardware limitations.
Sentiment score
7.6
FortiGate NGFW is effective for businesses of all sizes but faces scalability and cost challenges for larger enterprises.
Sentiment score
6.5
OPNsense is scalable for diverse organizations, efficiently supporting different user volumes, with some challenges in high-volume voice traffic.
They scale up really well from smaller models like the FortiGate 40 and 50 to bigger sites with the FortiGate 100 for more throughput - up to enterprise datacenters.
The variation comes in terms of the interfaces and throughputs, but from a security perspective, you get the same benefit, irrespective of whether you have an entry-level unit or an enterprise.
We determine sizing based on multiple factors: number of users, available links, traffic types, server count, services in use, and whether services will be published.
What it allows us in terms of connections to other companies is a straightforward solution that you don't have to use something else.
In my organization, there are 400 users, and OPNsense serves as our gateway and proxy for all of them.
Aside from these aspects, it demonstrated good scalability.
It supports routing, VPN setups, and traffic monitoring with additional packages like Snort and Suricata.
 

Stability Issues

I would rate the stability of Fortinet FortiGate a ten out of ten.
We have not had any problems with the operating systems or maintenance of subscriptions.
In some cases, you need to restart it, but mostly, it's working flawlessly, especially if you have an HA environment, high availability.
In my experience, there are usually no significant stability issues with FortiGate Next Generation Firewall (NGFW).
Stability-wise, I rate the solution a ten out of ten.
It just doesn't respond, so I have to restart it over and over again to try to figure out what the problem is.
OPNsense is the same, but it does have a way of installing the Realtek drivers, which gives you a lot more stability overall on the system.
 

Room For Improvement

Fortinet FortiGate needs enhancements in firmware, usability, integration, support, reporting, VPN, cloud integration, and documentation for seamless use.
FortiGate NGFW requires improvements in user-friendliness, integration, support, costs, and compatibility, with enhancements needed in key features.
OPNsense faces challenges with integration, user interface, documentation, scalability, performance, and security features, needing enhancements in various areas.

Investing in a solution that can accommodate such growth would be more cost-effective than repeatedly purchasing new hardware.
The constant daily revisions necessitate meticulous identification of the relevant documents to prevent the use of outdated information that could jeopardize our environment.
Improvements could be made when companies expand and need better equipment and more licenses.
Configuring these services is quite complex and not very user-friendly, requiring technical steps that are difficult for normal users to understand.
When a site is blocked, it is necessary for me to consult the logs to understand what the Next Generation Firewall policy has blocked.
For high availability, it's crucial to have a method in place where a designated component oversees the entire process.
The user experience when we create policies can be made easier.
Some of the features include classified traffic and better blocking of newly registered DNS domains.

Featured Reviews

Jorge Martínez - PeerSpot reviewer
Offers good SD-WAN capabilities and integrates easily with Fortinet devices
I am not part of the initial setup or deployment process since I work in presales. The setup or deployment is quite easy, as you can do a one-touch deployment that automatically connects to the FortiManager cloud when you connect it to a broadband or dynamic IP, allowing you to start the configuration from that point. We usually sell it for on-premises setups. It's on the cloud only when the client has virtual machines or their own service. Sometimes they have a service on the cloud like AWS, but it's more difficult to sell now because AWS has an e-commerce option where you can buy FortiGate directly. The only thing you need is someone to manage and configure.
Juan Solano - PeerSpot reviewer
Implementation improves efficiency and provides greater visibility over issues
One of the most valuable features of FortiGate Next Generation Firewall (NGFW) ( /products/fortigate-next-generation-firewall-ngfw-reviews ) is the ease of usability it offers. It is quite easy for me to learn to use. Additionally, FortiGate Next Generation Firewall (NGFW) has improved our efficiency in setting up security and provided us with more visibility over some issues and incidents we previously faced.
Akram Zaki Hussein - PeerSpot reviewer
Robust network security and management offering a user-friendly interface, open-source flexibility, and cost-effectiveness, with challenges regarding initial setup and the absence of official support
The interface is user-friendly, but there's room for improvement in terms of intuitiveness. The bundle management aspect requires additional attention to make it more intuitive, especially for inspecting high-level traffic. This is crucial, especially for larger companies where the existing features might not be the most optimal choice, given limitations like printer constraints. For high availability, it's crucial to have a method in place where a designated component oversees the entire process. Given that OPNsense plays a pivotal role as a firewall, safeguarding against various threats, having a reliable backup ensures uninterrupted protection even if unforeseen events impact the primary virtual machine. It would be beneficial if OPNsense supported additional virtualization platforms like Hyper-V from Microsoft and VMware, similar to how Kaspersky has integrated them.
