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.

NAC Support at Rah Infotech Pvt Ltd
Currently, we are experiencing a general outage of one of the main internet service providers of the Dominican Republic, and we have not been impacted in our operations because with SD-WAN, we have another internet service provider and we are working with the second WAN connection without any disruption.

Room For Improvement

Fortinet FortiGate users seek better integration, pricing, stability, security, support effectiveness, GUI ease, and documentation improvements.

When I reach the technical support, they give solutions that do not help me much, so I try to search the internet for other users' experiences to find solutions.

When I'm doing filtering at times, it doesn't filter the items properly.
Systems Analyst at a construction company with 1,001-5,000 employees
 

Setup Cost

Fortinet FortiGate offers cost-effective, scalable solutions with competitive pricing, yet some users find advanced feature costs high.
Portnox offers flexible, fair pricing with annual licenses, negotiable fees, and subscription-based options, appealing to larger organizations.
Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us.

It offers cost savings as it is generally cheaper than the competition.

We got a firewall and gave an SSL VPN to my client to connect to their servers, after which, such kind of activities involving ransomware attacks stopped.

They put in a thing called the FortiCookbook, which is very easy to read with real-life scenarios that make networking tasks like joining networks very straightforward.

Windows Server Administrator/ IT Support Officer at a financial services firm with 5,001-10,000 employees
It is possible to find the MAC address in the switch, but in Portnox, it is very useful to see the status of those ports, and that increases our security.

Network Security Engineer at Arrow PC Network Pvt Ltd
Unified security and sd-wan have improved uptime and cut wan costs for multi-site branches
Users report stability issues in certain versions, which requires regular updates. Real-world attacks have also highlighted the need for urgent patching of vulnerabilities.Fortinet FortiGate, while a powerful and feature-rich web firewall, could improve in areas like firmware stability, documentation, and ease of use. The learning curve can be steep for some users. For beginners, support quality can vary, and frequent updates with occasional vulnerabilities call for careful patch management. However, once Fortinet FortiGate is configured, it remains highly reliable and efficient. Customer support needs improvement, as I find it very slow, with reports from other users reflecting that customer support is inadequate.
Maurice Mwaura - PeerSpot reviewer
Product Manager at Applied Principles Limited
Unified access control has improved compliance visibility and simplified passwordless access
There is work to be done when it comes to making the solution more seamless. For example, when a user is denied access, they would need a way to maybe self-resolve themselves, perhaps a way to generate a ticket on their own, something around resolutions. When it comes to users using the product, that is where good products are differentiated from products that are a bit of a challenge. Portnox has much to do in terms of their reporting. The generated reports need improvement. Things that other tools would say are normal are usually not present. For example, there is a page called NAS devices or NAS network that is able to show the switches that have been managed. Currently, there is no way of generating an easy report or an easy way of just generating something to tell the customer what they have been able to achieve so far. This is not done yet and is still very manual. I think there is work to be done there. More integrations around the various products being used would be beneficial. So far I have not encountered any major challenge. Where there was a challenge, I think support came in and helped us resolve. In fact, most of the challenges are not with the product; they are with the customer environment. I think that is just to update their documentation where they have come across a new vendor for easier integrations in the future.

Sophos UTM vs. Fortinet FortiGate
I have used both Sophos and Fortinet products in production and I have found the Sophos UTM appliances (hardware and virtual) to be a better fit most of the time -- with a few caveats which I will touch on below. In both instances, the transition from TMG will be mostly straightforward. The main…
