Yati Gharat - PeerSpot reviewer
Chief Technology Officer at Litmus
Unified security management has simplified data center protection and optimized branch connectivity
In my opinion, a potential area of improvement for Fortinet FortiGate is that while it has a pretty good dashboard, which is not an issue as such, when we talk about hardware parameters, sometimes the hardware gets pretty heated up. Given the amount of traffic going through it, that is fine. However, the heat of the hardware has to be looked into. Fortinet FortiGate firewall is good, but other products like the switching part and all that fabric, in handling very audio-video traffic, sometimes it struggles on the switching part, but on the routing part, it is fine. On the firewall part, it is good; there is no issue as such up till now. Additionally, I suggest that Fortinet can add software which is in a controlled way, particularly regarding AI and ML. It should not happen that the AI/ML takes certain decisions which are not beneficial for the organization. The control should remain with the team members who are responsible for configuring this firewall.
Tejas Jain - PeerSpot reviewer
Principle Cloud Architect at a tech services company with 11-50 employees
Has provided strong traffic visibility and efficient policy management for advanced network environments
Palo Alto Networks K2-Series could be improved, though I don't think of much. I'm unsure how widespread the adoption for K2-Series alone is. Looking at the base Palo Alto capabilities, they are going in the right direction. K2 specifically about its efficacy with all these 5G protocols, the GPRS tunneling protocol performed without many hiccups during testing. With AI, if there is a Precision AI bundle that you're planning on exploring, then that definitely needs a significant uplift because currently it doesn't work for all the known models. There are many false positives that need to be addressed. While it's still ahead of its competitors, on the AI security side, there is quite a room for improvement.

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…

In the best tradition of these questions, Feature-wise both are quite similar, but each has things it's better at, it kind of depends what you value most. PA is good at app control, web filtering and such like, they have always been top of the pile there. The GUI is very good, and their product is very user-focused.
