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.

Integrates seamlessly and helps with real-time threat response

Since the solution we offered was a complete suite with Fortinet FortiGate-VM, it was easier for them to manage because they have FortiManager as well. The main reason they wanted to position FortiGate in the cloud was so that they could easily deploy through FortiManager. That was the selling point we had for them. Especially for their multiple branches, where they had approximately 60 sites, and some assets were in AWS, it was really a good deployment opportunity. FortiManager and FortiAnalyzer were also part of that solution.

A highly scalable solution that helps monitor and block undesired, non-standard traffic

Zscaler Cloud Firewall is a cloud-based solution. Zscaler Cloud Firewall is a good product. Since it's a SaaS product, most of the maintenance of devices is eliminated, and it is bundled with your secure web gateway. People should use Zscaler Cloud Firewall for their remote users or work-from-home users. Overall, I rate Zscaler Cloud Firewall a nine out of ten.

Quotes from Members

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

Pros

"FortiGate also makes GRE tunneling possible."

"Fortinet FortiGate protects against internet-based threats, both internal and external. It is scalable, stable, easy to use, and easy to install."

"Its stability is the most valuable."

"The reporting and monitoring are very good."

"It is easy to set up."

"The most valuable feature of the solution revolves around SSL VPN."

"We use the filtering feature the most. It has filtering and inbuilt securities. We can create customized rules to define which users can access a particular type of site. We can create policies inside the firewall."

"Fortigate is very scalable to serve our customers' needs. We have scaled already from fifty to more than a hundred instances of Fortinet FortiGate. Around 20 staff are required for deployment and maintenance, mostly engineers."

More Fortinet FortiGate pros

"What I appreciate the most about Fortinet FortiGate-VM is that it is not much different than hardware appliances."

"The most valuable features of this solution are the integration within the environment, with centralized reporting."

"The ease of access and user-friendly setup is a valuable feature. Fortinet proves to be particularly straightforward to configure, offering simplicity without complexity. Moreover, visibility is easily attainable due to certain factors. Price, implementation, and budget considerations play a role. When it comes to Cisco implementation, the process tends to be more intricate, which many customers find unfavourable for their business needs."

"The most valuable features are the web proxy for protection and web gateway for deployment."

"Fortinet FortiGate has positively impacted our organization by allowing us to scale fast."

"Fortinet FortiGate-VM is easy to use."

"I've found the UTM features and the SD-WAN to be most valuable."

"The performance overall is very good."

More Fortinet FortiGate-VM pros

"I like the ease of deployment and its flexibility. We don't need to deal with license, quotes, procurement, delivery, and installation. Everything is software-based, and it's very easy to operate."

"It is a stable solution."

"If malicious traffic attacks our on-premises servers, then it gets blocked by Zscaler Cloud Firewall."

"The scalability is okay. We have around 2200 people using this solution."

"Zscaler Cloud Firewall understands the applications in the current generation and adapts to the present generation cloud applications."

"Most of the features that Zscaler has to offer, we will deploy."

"The solution offers good sandboxing."

"The initial setup is straightforward."

More Zscaler Cloud Firewall pros

Cons

"It would be ideal if they had some sort of GUI interface for troubleshooting and diagnostics."

"With the reports, you can see it, and you can get good feelings so upper management can go, "Oh, wow. That looks pretty." However, it's very basic."

"There could be more modifications."

"I think that the infrastructure for the VPN could be improved. The way that it is bundled also made it difficult to use and sell as it is too expensive."

"The main thing they have to improve in Fortinet FortiGate is the technical support; the rest of the features are good enough. We can handle them, but sometimes you really need support, and in that case, we are not getting it at the proper time."

"The firewall engine is not so strong as of now, in my opinion... My second concern is that, while they have Zero-day vulnerability and anti-malware features, the threat engine needs to be strengthened, its efficiency can be increased."

"The performance can be improved."

"There is a lot of improvement needed with SSL-VPN."

More Fortinet FortiGate cons

"The scalability feature of the solution has certain shortcomings, making it an area where improvements are required."

"Data backup functionality could be included in the product."

"It would be better if it could provide you with options before completely blocking anything through the web filter. If you are doing a deep SSL inspection on the site if it says it's expired, it doesn't give you the option to continue at your own risk. I can't say that it's bad, but SSL internally isn't really a requirement. However, its security features can help. Right now, we have people going out and spending on purchasing the SSL certificates for internal sites."

"In the next releases, it would be nice to see central cloud management."

"The block, the clarity, the quarantine command, is not very user-friendly. You would have to do everything through the command line and I would have preferred if it wasn't a CLI."

"The management tools should be more user-friendly."

"In the Philippine market, where cybersecurity is still growing but not yet fully mature, we have many clients who have Fortinet FortiGate-VM or hardware. However, we cannot really position the Fabric if the licenses, renewal parts, or other components have monetary requirements that hinder full utilization."

"It has a monitoring tool, but it could be improved."

More Fortinet FortiGate-VM cons

"If I can get rid of Jetscaler, I will use Twingate for sure."

"It would be better if they improved their policy, package visibility, and flexibility while we're creating rules for inspection. It could also be cheaper or more things could be included in the basic package. In the next release, I would like better coverage in the Asia Pacific region and better quality of service."

"Because it's on cloud, it doesn't allow application of extra settings."

"Instead of the standard license, they should certainly provide customers with the visibility to access and view the logs."

"Zscaler Cloud Firewall should have a better understanding of all dynamic cloud applications."

"Certain criteria need to be met if you want to scale this solution."

"They do not provide a few components that are fundamental to differentiate the products"

"There are several areas for improvement. Firstly, the GUI is outdated, with noticeable lags and delays, especially when generating reports for past transactions."

More Zscaler Cloud Firewall cons

Pricing and Cost Advice

"The license of Fortinet FortiGate should be reduced."

"It has a competitive price."

"Fortinet has one or two license types, and the VPN numbers are only limited by the hardware chassis make."

"Fortigate's pricing is competitive."

"It is not the cheapest one, but its price is very competitive."

"It has been two years. I don't remember the actual price, but it was affordable. We buy the boxes and then use the license for three years."

"They are more expensive than others."

"It's an expensive solution"

More Fortinet FortiGate pricing and cost advice

"It has a flexible pay-as-you-go pricing model."

"It's not a cheap solution but it comes with its benefits."

"We have been waiting a long time for the vendor to give us licenses, it has been five months and we are still waiting. However, the price is reasonable."

More Fortinet FortiGate-VM pricing and cost advice

"There is an annual license required for the use of the Zscaler Cloud Firewall."

"It is expensive for small businesses."

"There are different subscription models available."

"There are licensing costs, and I would not say that it's a cheap vendor."

"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing an eight out of ten."
