Regional Manager at Orange
Centralized control has simplified cloud access and has improved operational visibility
If they can have better firewall features as their competitors have, such as Fortinet and Versa, that would help to place this solution better so that we can address security related things. If they can have all the IPS, IDS, everything built on all the edge devices, whether physical or virtual, that could be one improvement. Actually, if customers are existing Cisco customers, if Cisco can be more flexible to leverage the existing investment, that could be another important aspect to save on cost and be more competitive from a pricing perspective. Overall, the pricing or the segment that Cisco deals with is a bit premium, which they charge a bit premium against the competition on the licensing, hardware, and services. The implementation is not straightforward. You need a specialized partner or specialized people who can implement this. It can be simplified a bit from that perspective as well. Mostly the way we implement the policies for a big environment requires a lot of things that we need to take care of. If that can somehow be improved, because they have different components, like they have vManage, they have vSmart, and vBond and all these components have to work with a certain flow that they need to follow.

Practice Head at a consultancy with 11-50 employees
Unified security has protected diverse environments and supports consistent policies everywhere
I would say 8 out of 10 regarding the stability of Fortinet FortiGate. It requires a lot of bug fixing and what I understand, Fortinet is fast enough to provide bug fixes and patches, but usually I suggest Fortinet should do thorough testing of their releases and software releases and once probably they can reduce the frequency of new releases but make it stable. That's what my recommendation is. As far as the core objective of Fortinet FortiGate is concerned, I think they are meeting the targets but I guess for rolling out new features and new updates, they are doing a bit of hurry just to cope with the market dynamics. But possibly, I understand that they are compromising on the quality of the software and stability. So over there they have to improve. Rest of the aspects, I guess they are doing pretty good. We are happy. Regarding my experience with Fortinet FortiGate in comparison to maybe some other vendors such as CyberArk, Fortinet is in the top three and they give a lot of competition to their nearest peers in the market. But I guess Fortinet is really struggling in software-defined LAN, Wi-Fi, and FortiSwitches space. So they have to make their products more affordable in Forti-switching and Forti-WiFi space. They are not able to compete effectively with the nearest competitor HP Enterprise and HP Aruba.

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…
