Cloud features enhance security measures and simplify network management
I've dealt with many firewalls, such as SonicWalls, UniFi, pfSense, and Cisco. We found SonicWall very confusing for the average network engineer or network administrator. I don't recommend SonicWall due to its hard-to-find auditing process for exploits. Although they have fewer exploits, when they do occur, they're significant. With Fortinet FortiGate, you can access the whole firewall, with no hidden spots. pfSense is great, however, it requires a lot of manual work and has no Cloud Connect or easy management from an MSP's perspective. Palo Alto is another option that's great, but their price point isn't for everyone, especially for medium and small businesses; a $10,000 investment doesn't necessarily fit into most budgets. UniFi is another product we've started to use more alongside Fortinet FortiGate, as they have almost all features without a license, with advanced rules that are relatively inexpensive compared to Fortinet FortiGate's $1,500 a year. Fortinet FortiGate and UniFi are the two firewalls we primarily deal with. My opinion is that UniFi has better integration and oversight of the environments compared to Fortinet FortiGate.

Beneficial AI detection, helpful support, but modern UI needed
The initial setup of the Hillstone I-Series Server Breach Detection System requires a bunch of steps starting with installing the hardware and setting it up. However, most of the setup is done by the vendor. I rate the initial setup of the Hillstone I-Series Server Breach Detection System an eight out of ten. The vendor provides free training in the software provided.

Centralized security management has improved VPN reliability and simplified daily operations
WatchGuard Firebox is a strong and reliable platform overall, but there are a few areas where improvements could make the experience even better. One area is the user interface and navigation in some management tools. While the platform is powerful, certain configurations and troubleshooting workflows can feel less intuitive compared to some newer cloud-native firewall platforms. Another point is reporting and log analysis. Although the logging features are very useful, deeper analytics and more customizable reporting dashboards would make security monitoring much more effective. Firmware upgrades and policy synchronization can sometimes require careful planning to avoid security interruptions. Overall, the core security and VPN functionality are very solid, but improving usability, reporting, and automation would make the platform even stronger. One area that could be improved is the learning curve for new administrators. While experienced engineers can work with the platform effectively, some advanced networking and security configurations can be a bit complex for junior technicians. More guided configuration workflows, smarter recommendations, and simplified troubleshooting tools would make onboarding easier. Another improvement would be more flexible reporting customization for executive-level and client-facing reports.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We receive substantial help from Fortinet, which is very valuable as they assist us in choosing the right solutions. If we need configuration assistance, they can send specialists who help design the solution."
"FortiGate is a scalable product and our customer has approximately 2,000 users."
"We’ve gone from only selling Fortinet FortiGate as an accessory to creating an entire department in our business dedicated to selling Fortinet products in the span of three years."
"The features that I have found most valuable are that it is good to use, and most importantly, the pricing, and the customer especially likes the discount when they trade up or something like that."
"The firewall engine is very good, very suitable for picking up Zero-day threats, and it has protected us from two or three instances, thanks to this engine."
"Their reliability and their policy of pre-shipping replacements when a unit has failed."
"We never had any issues or problems related to stability."
"Fortinet FortiGate protects against internet-based threats, both internal and external, and is scalable, stable, easy to use, and easy to install."
"The most valuable features of the Hillstone I-Series Server Breach Detection System are the AI detection and monitoring of common threats."
"One or two people can maintain and support the solution. The maintenance is not difficult."
"WatchGuard Firebox is the most powerful firewall for Wi-Fi security."
"The policy monitoring and allowing different traffic flows are the most useful features for us; regulating which traffic comes in and out."
"I think it is the best solution in the world, judging by its price and quality."
"I find this solution very easy to manage. The web manager and Firebox key features are particularly impressive for cloud applications. That's why I often recommend this solution to our clients. It has good threat management capabilities and works against different types of threats."
"The tool's most valuable feature is the dashboard."
"It saves us a lot of money over MPLS connections, about $125,000 per year."
"[A] valuable feature would be the branch office. We have five offices throughout the United States, and it coordinates the connections of those offices."
"The basic functionality is fantastic. It has been performing well. I generated a report on one machine, using that as the deployment machine. When scanning the network, it discovered machines on the network and deployed the same endpoint protection from that one machine I have on my network."
 

Cons

"The solution is very expensive."
"I would like to see improvements in the IPS/IDS feature to enhance protection against attacks from attackers, including ransomware protection."
"The support is not good because I generally search for solutions online. When I open a case, they usually identify it as a bug they are working on."
"We sometimes have issues when carrying out inspections because the system slows down and our clients complain about it."
"Its load balancing feature could be easy to configure."
"I believe there is room for improvement in machine learning and AI in Fortinet FortiGate. I would like to see more automation regarding AI and machine learning in Fortinet FortiGate."
"MTBF: Hardware failure is more common when compared to SonicWall or Cisco ASA."
"Lacks training for new features."
"The UI dashboard view needs to be improved because it is ugly. If it was more modern it would be better. Additionally, better integration with other databases would be good."
"Hillstone I-Series Server Breach Detection System can improve by having more anti-spam features that will hopefully eliminate all of the other threats."
"The performance of the solution's processor needs to be faster."
"There is a problem with the RAM - it's eating up resources. The RAM utilization sometimes reaches up to 80% - 95%, and what we do is just restart the firewall."
"The user interface and configuration can be improved."
"I would like to see the devices made more flexible by adding modules to increase the ports that we can use."
"The user interface for WatchGuard Firebox has room for improvement. Right now, it's a bit complex to work with and could be easier."
"In terms of usefulness and reducing frustration, at my level, it's a three."
"The solution is a bit confusing and there are unusual complications with setup."
"The solution needs to improve its accessibility."
 

Pricing and Cost Advice

"Fortinet FortiGate's price can be reduced."
"The solution is more expensive than Sophos. It could be cheaper. The licensing is on a yearly basis. We have had it for about three years. We must only pay extra for the license, additional requirements, and the hardware box."
"If you are looking for a quality product, it will come at a higher price. Expecting them to be significantly cheaper is unrealistic. In terms of pricing, it is a bit costly. However, the functionality and support offered are worth it."
"There is a licensing fee; it is on a yearly basis."
"Its price is good."
"The price of Fortinet FortiGate is better than Cisco, Check Point, and Palo Alto. In terms of pricing, it's probably a better-priced firewall solution overall."
"The pricing depends on the FortiGate model we are using, ranging from $3,000 to $20,000 US dollars."
"Currently, we are paying about $1,500 a month for three sites."
"The price of the solution is good. It is less expensive than the other solutions in the market. There are not any additional features or hidden costs."
"The cost was somewhere in the vicinity of $2,000 to $3,000 for each one..."
"The subscription that was purchased is for three years, but it is usually for one year at a time."
"There is a license required to use the solution and we pay annually. The price could be reduced because it is a bit expensive."
"I buy a three-year renewal on the main device, which is usually around $3,000 to $4,000. They usually upgrade the device when I do it. You get a big discount when you do three years."
"I spent $600 or $800 on this product and I'm paying a couple of hundred dollars a year in a subscription service to keep the lights on, on it... It works out to $100 or $200 a year if you buy several years at once. It's fair."
"I usually tell people that it's really affordable as well, particularly compared to Cisco."
"The two larger devices are about $1,000 each and the smaller ones are about $500 or $600 each... It's cheaper and you have more control because it's self-managed."
"Despite the fact that there is always room for improvement, the current pricing of the solution is still lower compared to its competitors."
