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.

Simplifies the management of complex data networks, but its technical support could be improved
Sometimes, we have to use SD-WAN support for the solution, which can be improved by adapting some features that will help our approach to network services. The solution can adapt some of the tools where we, as network engineers, can adjust to the changing application needs. Also, the solution can provide us with multiple support, allowing us to create a network segment. The solution’s technical support could be improved.
Carlos Snel - PeerSpot reviewer
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

"Anti-Spam web content filterinG."
"We use a southern institution that's audited for IT security and the reporting that automatically comes off the unit makes it much easier to meet compliance standards and makes it easier as far as the amount of time that has to be spent to compile that information. If you get your reporting set up correctly when you initially set it up, you just select the one you want and hit print. The auditing trail on it is the best feature."
"Our experience of using Fortigate is excellent and we strongly recommend it."
"Finally there is a UTM Fortinet. It has given me complete oversight of my network in a centralized fashion, so I know what is going on at all times."
"Fortinet solution has received great feedback."
"Since deploying FortiGate 3401E clusters, we have observed: Dramatic Reduction in Risk Exposure—blocked peer-to-peer and unauthorized applications (e.g., BitTorrent) at the perimeter and east-west segments, eliminating a major source of malware and bandwidth abuse."
"Easy to use support and licensing portal as well as activation process."
"The product is user-friendly and easy to manage."
"GajShield has improved our mobile device-based connectivity."
"It is an easily scalable solution...The initial setup was very easy."
"The solution's outcome is very high, and we often use it in a very high-traffic environment."
"It is a stable solution."
"GajShield Next Generation Firewall's best feature is the network DLP."
"Gajshiled's enterprise cloud and DLP-level features give it an advantage over other products."
"The most valuable feature of the GajShield Next Generation Firewall is the user-friendly settings, dashboards, and anti-threat protection. Additionally, the solution upgrades frequently which is good because we receive new features."
"Once it is configured, it is very stable, and we don't get any calls from our clients unless they have some specific requirement, like port forwarding or something."
"Most of the features that Zscaler has to offer, we will deploy."
"Includes advanced tech protection."
"Zscaler is one of the leading vendors in the cloud space."
"If malicious traffic attacks our on-premises servers, then it gets blocked by Zscaler Cloud Firewall."
"Zscaler is the Rolls Royce for this kind of solution."
"The initial setup is straightforward."
"I like the advanced tech protection Cloud Sandbox, it's a nice feature."
"The technical support from Zscaler was excellent."
 

Cons

"The inability to change passwords when using FortiGate firewall and relying on a local FortiGate database for account creation can be problematic, particularly in non-Active Directory setups."
"Some of the features in the graphical user interface do not work, which requires that we used the command-line-interface."
"There are some complex administration tasks in their administration portal. That needs to be improved."
"Improvement is needed in the Web Filter quotas to restrict users with allocated quotas."
"We have experienced a number of failures when trying to upgrade firmware and the process takes a long time. We only experienced this when doing major upgrades between versions."
"I would rate the technical support of Fortinet FortiGate as a five because it is not as strong as Cisco. Additionally, the turnaround time is very high compared to Cisco."
"I would like to see improvements in the IPS/IDS feature to enhance protection against attacks from attackers, including ransomware protection."
"If I had any criticism that I would give FortiGate, it would be that they need to stop changing their logging format. Every time we do a firmware upgrade, it is a massive issue on the SIM. Parsers have to be rebuilt. Even the FortiGate guys came in and said that they don't play well in the sandbox."
"We face issues with some configuration parts that we don't understand in the solution, and sometimes we face issues with the VPN connection."
"GajShield Next Generation Firewall could improve the flow of the settings. If somebody's using a Cisco firewall or any other brand and they want to use GajShield Next Generation Firewall the platform's UI is a bit different. If it was more similar to the others it would be better."
"Gajshield can improve SD-WAN compatibility at an enterprise cloud level."
"We raised a support ticket, and the project didn't get a proper response. There was a skill issue in TAC support."
"GajShield Next Generation Firewall would be improved with the addition of a load-balancing feature."
"The firewall configuration and administration screens could use some improvement."
"Sometimes, we have to use SD-WAN support for the solution, which can be improved by adapting some features that will help our approach to network services."
"The UI for the administration of the firewall needs a lot of work."
"There are several areas for improvement. Firstly, the GUI is outdated, with noticeable lags and delays, especially when generating reports for past transactions."
"Because it's on cloud, it doesn't allow application of extra settings."
"Its technical support services could be better."
"The product could improve its integration with some legacy systems."
"Zscaler Cloud Firewall should have a better understanding of all dynamic cloud applications."
"Zscaler doesn't do intra site segmentation, therefore, if you want segmentation within a branch office, that kind of traffic flow is not well addressed."
"I don't have the visibility of a control dashboard or a network management system."
"When it comes to customer support, there is room for improvement in Zscaler's service."
