Henry Rosenstiehl - PeerSpot reviewer
Solution Architect at Sonda S.A.
Comprehensive support and ease of implementation enhance operational efficiency
With Cisco Catalyst SD-WAN, I have centralized orchestration and management. The transport independence of MPLS or connectivity and internet connectivity is another excellent feature. End-to-end segmentation is also provided. I use the application-aware routing feature. Cisco Catalyst SD-WAN supports dynamic police-based routing decisions based on application type or different performance metrics such as jitter or latency. The benefit of that feature is that it improves user experience. The principal benefit of application-aware routing is that critical applications are prioritized or routed over the best performing paths to reduce outages and service degradation. There is full visibility of applications. Cisco Catalyst SD-WAN has integrated security features which include base firewall, URL filtering, IPS, and secure segmentation, and it supports integration with other Cisco products such as Umbrella or Snort. This feature is beneficial for the client because the information is secure. It is important that Cisco Catalyst SD-WAN supports cloud, on-premises, and hybrid environments for my organization because it allows for scalability and faster deployment in the cloud. It reduces operational needs because I don't need to manage physical controller hardware, and updates and maintenance can be centralized and automated. The zero-touch provisioning feature is very important for the speed of deploying new branch locations. I can deliver the device to the branch, and it is important because simplified deployment makes the implementation start more easily since devices are auto-configured and authenticate without manual intervention.

A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

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…
