IP Network Security Specialist at MTN Ghana

Process-Level CPU Visibility: Introduce detailed CPU-usage metrics per subsystem (e.g., IPS engine, logging) so administrators can quickly identify and address performance spikes.

Analytics with FortiAnalyzer. Being able to pull in logs not just from our FortiGates but from all our other firewalls and then get them in one view has been a game changer. Whether I’m building an executive dashboard or doing a deep dive forensics session, I get everything I need without navigating consoles.Straightforward Application Control. FortiGate spots and blocks unwanted apps (eq. like BitTorrent or streaming services) with accuracy. Segmentation with VDOMs. We’ve carved our data center into four logical ‘mini-firewalls’ enterprise, core, billing, and WAF—all on one box. Each has its own rules and logs, and any traffic between them still gets inspected. It’s like having multiple appliances without the extra hardware. Always-Up-to-Date Threat Feeds. Daily signature updates and AI-driven threat sensing mean we’re blocking the latest vulnerabilities almost as soon as they’re announced.

Offers good features like URL filtering, IPS, and IDS to users

We received an update for the tool in July. The update was provided for the tool as there was a problem with the firewall, where too much memory was consumed, and the firewall was hanging a lot. When we updated the tool's features, everything became okay. The tool only had some memory-related problems. It took the tool a month to fix the issues.

Carlos Snel

Director at Aquila ICT Solutions

Has streamlined secure deployments across large enterprises while offering reliable protection and intuitive management

The centralized management console, also referred to as the Zscaler dashboard, impacts the ability of my customers to respond to security incidents significantly. I see it as user-friendly, and clients are really happy with using it, which motivates them to keep using Zscaler Cloud Firewall because they enjoy the GUI. It's very intuitive, making it easy to navigate alerts and incidents. My clients rarely have questions about where to find specific information once Zscaler Cloud Firewall is running. The interface speaks for itself, requiring little to no additional training, which is a major plus. Advanced threat protection features in Zscaler Cloud Firewall are practically the key component that every customer wants. Unfortunately, it is an option and not included in the basic package. Clients need to pay for the next higher bundle to access it, but practically all clients I have dealt with want this feature 100%. Regarding visibility, I can confirm that Zscaler Cloud Firewall indeed includes a feature for application layer visibility embedded in the service. It provides visibility into what you're doing, which is especially interesting nowadays when discussing AI tools, as companies do not want their employees to copy-paste sensitive information into AI systems. We have seen cases such as Samsung's chip design where sensitive info got exposed. The visibility of applications, including cloud applications and AI tools, is significant for compliance with data policies, and you can also run reports and alerts on it.

Quotes from Members

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

Pros

"Fortinet FortiGate is a stable and affordable product."

"Virtual Domains (VDOMs) are a feature that we found valuable."

"The most valuable features are SD-WAN, application control, IPS control, and FortiSandbox."

"I am "headache free" that I don't have to categorize all the websites and that security has been pre categorized by the people, and that the services are getting updated. At least one part of my problem is over."

"Fortinet FortiGate has many valuable features, such as IDS, and intrusion detection. It has security features that are in part with the technologies that are available in the market."

"The combined license for the network, the next-generation firewall, and the integration with SD-WAN for all branches are what I consider to be the best features. It's effective for multi-branch customers."

"This is an easy solution to deploy."

"I like the common administration and the possibility of adding Fortinet defense systems."

More Fortinet FortiGate pros

"Very reliable solution with good scalability and straightforward implementation."

"The initial setup was straightforward. It only took a few hours to deploy."

"The most valuable feature of the solution is the ransomware protection that the tool offers."

"Stability-wise, I rate the solution a ten out of ten."

"Five out of five ROI."

"The most valuable features of the Hillstone E-Series are its hardware capacity, innovation, and the throughput that the hardware can take."

"Working with the Hillstone E-Series has, from a remote perspective, allowed me to give my clients secure connectivity from a remote location to their offices or their servers."

"This solution has two main features that we find very valuable; a threat-intelligence option, and a web/application filtering option. The technical support team are very good and very quick."

More Hillstone E-Series pros

"With regards to ease, with regards to scalability, with regards to performance and support, those are the kind of top features that I would always look at and I have had a great experience in general."

"It helps a lot of companies to reduce their downtime. Also, It helps businesses in terms of being secured and protected from any threats."

"Zscaler is the Rolls Royce for this kind of solution."

"Zscaler Cloud Firewall can be used for blocking all the malicious IPs, unauthorized IPs, unauthorized sites, and unsanctioned sites, such as when many users use PDF converters and can upload confidential data that we can detect and block."

"Zscaler is still a very good product."

"Includes advanced tech protection."

"The solution offers good sandboxing."

"The product’s firewall and VPN package are fantastic compared to any other solution."

More Zscaler Cloud Firewall pros

Cons

"It claims it does DLP, but the degree and level of controls are very basic."

"However, apart from this, I don’t see a significant differentiator between FortiGate and other firewalls."

"One area for improvement involves FortiAnalyzer, specifically regarding the SOC part and log interpretation. Sometimes interpretation is very difficult."

"FortiGate is a complete solution, but it is very expensive compared with other solutions."

"Fortinet FortiGate can be improved by being more stable because when we look for logs or open a case, we always find a bug and then we have to upgrade it."

"The cloud management and automation capability could be improved."

"One issue that I have had is that sometimes I need to monitor the traffic, so I need to filter it according to the user and which user is using it the most. I experience a bottleneck most of the time, particularly at the peak time when the number of contracts and users are at maximum."

"One drawback of Fortinet FortiGate is that they provide two types of models: one with a hard disk and another without. The model without a hard disk has very low ROM where you can store very few logs, after which you need to upload it to the cloud or purchase a firewall with SSD. That's the only drawback."

More Fortinet FortiGate cons

"SSL VPN license cost is not cheap."

"The licensing model is very complex with many subcategories of licenses you can purchase. They could make it more simplified for customers to understand."

"Having frequent live webinars on a monthly basis would really help."

"The current usage reporting is very basic. I would like to be able to access more granular data."

"Support from Hillstone E-Series has a shortcoming that needs improvement."

"The tool provides just a general report. It does not provide a granular report. Hence, the tool should work on its reporting feature."

"The solution doesn't have a web proxy built into the system like Sophos. This is something they should work to change."

"The room for improvement would be the SSL VPN license cost."

More Hillstone E-Series cons

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

"There are some areas it could improve when it comes to blocking, we have to block some things manually. For example, if we block a top-level domain we have seen that the new IPs come through, the IPs are not blocked. There should be some more granular way of doing it. My only request is if you're blocking something at a top level, the sub-level sub-domains and all those other IPs should be blocked too automatically."

"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."

"Currently, the Data Leak Prevention is only for web filtering and there is nothing for email and the USB, so it would be an improvement if that could be included."

"The issue right now is probably that Zscaler is not providing web browser isolation."

"The issue right now is probably that Zscaler is not providing web browser isolation. Another solution, Menlo, offers this. For one customer, we had to send traffic to Menlo to do the isolation for us. It was requested by the customer so that they could integrate any iframe. Zscaler needs to add this type of feature in their next release."

"When it comes to customer support, there is room for improvement in Zscaler's service."

"The needed improvements involve scalability, which is something I wish they would address."

More Zscaler Cloud Firewall cons

Pricing and Cost Advice

"Fortinet FortiGate has different licensing models, depending on what you're going to do. Services included would depend on the license model. Licenses can be renewed annually."

"Its pricing is fine. It is on a yearly basis. Other than the licensing fee, there is no extra fee."

"Fortinet's pricing is more straightforward than other solutions. If Fortinet doesn't stick out when you're searching for a solution, you are a glutton for punishment. You only need to know two things when purchasing a Fortinet solution: your total bandwidth and bandwidth at the site. You need to estimate the future bandwidth with other solutions if your customer plans to upgrade."

"It is around $50,000 per month."

"FortiGate Next Generation Firewall costs our company around $12000 per year."

"While Fortinet FortiGate has a higher price point compared to Sophos XG, its user-friendly interface justifies the cost."

"Each feature costs money, so it is important to study your needs."

"Setup costs and pricing depends on many variables, but it's mostly affordable."

More Fortinet FortiGate pricing and cost advice

"The tool's pricing is reasonable. It depends on the model. The product's pricing is around 600 USD. You need to buy a software license to activate the features. You need to pay around 150 USD for that."

"Hillstone's pricing is economical and neither very high nor very low."

"The cost per year for licensing, and hardware, is approximately $850 for the basic plan."

"The licensing model is very complex with many subcategories of licenses you can purchase. They could make it more simplified for customers to understand."

"It comes at a significantly reduced cost while ensuring control and effectiveness."

"Zscaler is priced too high compared to the cost of Fortinet."

"It is not the most budget-friendly solution, but it's important to consider its overall value."

"The licensing is on a yearly basis. It is somewhere around 30 or 40 pounds per user for our organization."

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

"It is expensive for small businesses."

"There are different subscription models available."

"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."
