Manager, Information Technology Operation/Presales at TechMonarch
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.

Service provider benefits from effective email security management and seeks enhanced customer support
Reporting could be one of the areas for improvement, as they could put more reporting into Microsoft Exchange Online Protection (EOP) natively rather than requiring additional licensing or connecting to other parts of the Microsoft suite, but it depends on the license you have. There aren't significant concerns with Microsoft Exchange Online Protection (EOP), as it depends on what customers expect; if they expect more features, then it depends on what Microsoft 365 license they have. The important thing is to ensure they are using all the security features they get with their licensing. The basic one is Microsoft Exchange Online Protection (EOP). While it's nice to have more functionality, that's available through other licensing programs with Microsoft. While we'd prefer more features, as a basic tool, it's fine, but more advanced features come with the add-ons from other parts of the Microsoft 365 licensing. One feature that could improve Microsoft Exchange Online Protection (EOP) is automated malware detection, where it actually analyzes the file offline in a sandbox to determine if it's safe, potentially reducing false positives.

Makes defining policies simpler but lacks performance and modern features
WatchGuard Firebox is only deployed in one location within my customer's organization, and at the other locations, we are using Meraki and FortiGate. We plan to replace WatchGuard Firebox soon. My impression of the spam blocking capabilities of WatchGuard is not very favorable, as I don't think it is very capable. I haven't noticed effective web ratings or IPS signatures, which may be due to managing an older OS; I'm not certain about the performance of the newer versions. I am not aware of whether the transition to faster ports on WatchGuard Firebox supports maintaining productivity levels during peak usage times. Based on my experience, I would rate WatchGuard Firebox as five out of ten overall.
