Sentiment score

Users experienced cost reductions, improved security, enhanced performance, easier scalability, better threat protection, simplified management, and efficient resource utilization.
Clients are now comfortable and not wasting productive hours on IT support.
The automation part is giving us a cost benefit and speed; we can react faster.
It's a very useful tool to mitigate and protect your enterprise.
My ability to monetize it as a gateway security appliance to offer enhanced service offerings allows me to increase our price point.
 

Customer Service

Sentiment score
6.6
Fortinet FortiGate support is generally effective, but some users report delays and issues with complex problem resolution and communication.
Sentiment score
5.5
Untangle NG Firewall is praised for effective support, but challenged by limited resources and phone support availability issues.
Sentiment score
5.0
Zscaler Cloud Firewall offers responsive and knowledgeable support, though occasional escalations might cause delays, with room for improvement.
They offer very accurate solutions.
The quick resolution of issues with Fortinet FortiGate is due to the support of the company and the fact that the equipment is easy to work with.
I would rate the technical support for Fortinet FortiGate a ten out of ten.
They're able to remotely manage the devices if necessary for support.
They got back to me pretty quickly, the response time was fast, and they're knowledgeable.
The response and support are sometimes inadequate, which detracts from the overall experience of an otherwise impressive solution.
The technical support from Zscaler was excellent.
 

Scalability Issues

Sentiment score
7.1
Fortinet FortiGate efficiently scales for SMEs, though hardware upgrades can be challenging, with virtual deployments offering flexibility.
Sentiment score
6.1
Untangle NG Firewall offers high scalability, efficiently supporting diverse user bases from small offices to large corporations.
Sentiment score
5.3
Zscaler Cloud Firewall is scalable and easy to manage, praised for performance and user satisfaction across various regions.
They scale up really well from smaller models like the FortiGate 40 and 50 to bigger sites with the FortiGate 100 for more throughput - up to enterprise datacenters.
The variation comes in terms of the interfaces and throughputs, but from a security perspective, you get the same benefit, irrespective of whether you have an entry-level unit or an enterprise.
We determine sizing based on multiple factors: number of users, available links, traffic types, server count, services in use, and whether services will be published.
Since it can be put on any box, the scalability is fantastic.
In this case, Twingate will be very easy compared to Zscaler.
 

Stability Issues

Sentiment score
7.7
Fortinet FortiGate is praised for its dependable stability, minimal downtime, and robust performance, especially with regular firmware updates.
Sentiment score
8.2
Untangle NG Firewall is stable, with users noting reliability, high ratings, and improvements over time, despite rare hardware issues.
Sentiment score
6.4
Zscaler Cloud Firewall is stable, reliable, and well-rated, with minor performance issues and redundancy minimizing outages.
We're experiencing 99.999% availability consistently.
I would rate the stability of Fortinet FortiGate a ten out of ten.
Currently, we are experiencing a general outage of one of the main internet service providers of the Dominican Republic, and we have not been impacted in our operations because with SD-WAN, we have another internet service provider and we are working with the second WAN connection without any disruption.
I haven't had to mess with it too much; it's pretty stable.
There were some stability issues due to occasional latency and lags, particularly with the GUI and report generation.
 

Room For Improvement

Users seek improvements in FortiGate's performance, web interface, reporting, documentation, licensing, and training resources.
Untangle NG Firewall requires enhancements in support, management, mobile functionality, hardware, security, pricing, and on-premises deployment.
Zscaler Cloud Firewall needs improved features, better integration, enhanced support, wider coverage, affordable pricing, and a modernized interface.
Investing in a solution that can accommodate such growth would be more cost-effective than repeatedly purchasing new hardware.
While Fortinet claims to offer a comprehensive network solution, it falls short in addressing computer application issues, particularly server security.
When considering Sophos XG, which we also use, the logging and reporting functionality is notably more efficient.
The user interface, training, and general product innovation need improvement.
I haven't dug into the advanced features, but I think some of the advanced capabilities are probably where it lacks a little bit, with the filtering and firewall rules.
For now, there is no dashboard or network management system available for Twingate.
The reverse proxy feature for Data Loss Prevention (DLP) is missing.
I believe the integration of AI could improve the dashboard by making it more agile and effective in monitoring and predicting threats.
 

Setup Cost

Fortinet FortiGate offers robust features at a competitive price but can be costly, especially with licenses; long-term pricing negotiation advised.
Untangle NG Firewall pricing is seen as cost-effective but can become expensive with feature bundling and higher user counts.
Zscaler Cloud Firewall is flexible yet expensive, valued for tiered packages, with prices affected by user count and features.
Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us.
It offers cost savings as it is generally cheaper than the competition.
It is about 20% cheaper.
It's less expensive, especially because it has a lot of the pieces integrated into the firewall, so you get savings on that front.
Zscaler Cloud Firewall is quite expensive compared to competitors.
 

Valuable Features

Fortinet FortiGate provides robust security, seamless integration, user-friendly interface, and cost-effective advanced threat management for diverse network environments.
Untangle NG Firewall offers user-friendly, affordable security features ideal for small businesses, including VPN, web filtering, and cloud management.
Zscaler Cloud Firewall offers advanced threat protection, simplified management, and seamless integration, enhancing security with flexible policy customization and traffic control.
In terms of security, we have not experienced any security flaws or loopholes, and it has proven to be quite stable.
FortiGate has helped reduce the risk of cyberattacks that might disrupt our client's production.
These features help reduce our downtime, manage the ISPs, and deploy SLAs for all the website traffic.
The ease of use and the built-in and integrated features, including the apps that include OpenVPN, IPsec, and WireGuard VPN, are all built straight into Untangle NG Firewall.
The all-in-one gateway security functions and the ability to install it on generic equipment stand out.
It is really customized, a security policy that can be applied to the users so they can access only the resources I enable them.
Advanced threat protection features in Zscaler Cloud Firewall are practically the key component that every customer wants.
The biggest advantage of Zscaler Cloud Firewall is its consolidation of products.

Featured Reviews

Vasu Gala - PeerSpot reviewer
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.
MatthewSmith3 - PeerSpot reviewer
Thorough with all-in-one security functions and good affordability
The all-in-one gateway security functions and the ability to install it on generic equipment stand out. The centralized management console is great. I can template my installations and configurations. My ability to monetize it as a gateway security appliance to offer enhanced service offerings allows me to increase our price point. I provide it as a managed device to many of our clients. I take on the initial costs and charge them a monthly fee. They have threat detection.
Carlos Snel - PeerSpot reviewer
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.
