Ease of configuration and seamless integration enhance operational efficiency
The App Control feature in the Fortinet FortiProx * Deep Packet Inspection (DPI): FortiProxy analyzes traffic at the application layer to detect applications even if they use non-standard ports or are encrypted. * Application Signatures: Uses FortiGuard’s application signature database (constantly updated) to recognize thousands of applications. * Policy Enforcement: You can create policies to Allow, Block, Monitor, or Shape (QoS) based on application type, category, or specific apps.

User access management and threat prevention are enhanced with user-friendly controls
The best features Zscaler Internet Access offers include application control, tenant segregation, and PoP center regions which have low availability zones. The internet access is very successful and bandwidth speed is excellent. It also has application-based control, URL-based control, and SSL inspection capabilities, which are very useful. Additionally, the in-depth CASB segregation is very beneficial to us. One unique feature I found helpful is the tenant level restrictions, which we use to only access our organization's tenant level mail IDs, drives, and specific tenant level access while restricting public access. Zscaler Internet Access has positively impacted our organization as we have noticed substantial outputs and income. It has improved our security environment control and endpoint protection. It prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses. It has a toggle button to enable features entirely at the tenant level for all users onboarded into Zscaler Internet Access, resulting in much better outcomes.

Quotes from Members

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

Pros

"It is a really stable solution."
"The App Control feature in the Fortinet FortiProxy Deep Packet Inspection (DPI): FortiProxy analyzes traffic at the application layer to detect applications even if they use non-standard ports or are encrypted."
"It seamlessly integrates with various security products, enhancing threat intelligence and improving indicators of compromise."
"The most valuable features of Fortinet FortiProxy are its simplicity and performance."
"We can use Fortinet FortiProxy configuration for your network."
"It helps to secure the networks at the DNA level and ensure proper identification and filtering of DNS traffic."
"The most valuable feature is intrusion prevention (IPS) and antivirus profiles. These features help control user activity, ensuring that they access only permitted websites and protects from downloading viruses."
"The solution's stability is good."
"Overall, it's a good solution; we had very few issues during implementation, technical support is quite helpful and responsive once you get a hold of them, it has private access and has a lot of features inbuilt including DLP and CASB, and the solution is scalable and stable."
"Zscaler has helped protect our employees wherever they are working, by delivering safe web access."
"Zscaler is an expensive solution, but it's worth the price."
"Whether you are in a hotel somewhere, or in Africa, it does not matter. You will get the Zscaler protection presence anywhere."
"The cloud proxy and integration are some of the key features. Since there is cloud waste, we can quickly provision it and start working on the configuration. On top of that, they have added a few more features. They have integrated CASB, and file sandboxing is part of it."
"Zscaler Internet Access is very scalable, and requests for scalable solutions are met quickly."
"The most valuable features of Zscaler Internet Access include its capacity to scale, the security implementation capabilities, the ability to integrate public IPs related to clients so traffic presents on the internet as a client, and the facility to interoperate with SSEs while maintaining the same security mechanisms from on-premises to cloud environments."
"Zscaler, on the other hand, is more stable and also more secure."
 

Cons

"Fortinet FortiProxy should improve by adding more documentation and guides."
"Its web filtering capabilities could be improved."
"For IT administrators and managers, the reporting features are the main issues that should be addressed in order to improve the performance, security, and effective utilization of the product."
"Integration with existing infrastructure was generally easy, especially if you had tools like LDAP. However, I had to go through a lot of documentation as it was my first time working with a proxy server. We did experience some issues with certain web applications not working properly after implementing Fortinet FortiProxy."
"The hardware version is stable, but the VM version is not stable and contains bugs that cause issues."
"The tool's most valuable feature is its granular access control. For example, users can browse the main site if you allow access to Amazon, but it stops them from visiting secondary Amazon websites without specific permission. This granular control is really helpful."
"Fortinet FortiProxy should integrate AI/ML technologies. Its pricing needs to be more flexible."
"Its power supply process for some of the proxies needs improvement."
"I would like to see the ability to choose a pool of IPs for my company, set up rules based on them, and know that those IPs are not used by other companies."
"Zscale is providing a proxy IP, and most government sites will block traffic from a proxy. Also, we see some performance issues on the cloud side during DC failover."
"We use other similar products and find them to be a bit more preferable to Zscaler."
"Zscaler is one solution. It's a good solution, but it doesn't do everything."
"The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again."
"The deployment process of Zscaler Cloud Connector needs to be more user-friendly."
"They should enhance the audit reporting feature."
"Zscaler Internet Access's troubleshooting is very limited, and their textbook logs need to be more informative."
 

Pricing and Cost Advice

"It is a cost-effective solution."
"The tool's pricing is in the middle."
"It offers a more cost-effective solution than alternatives like FortiMail, FortiGate, and various Barracuda devices."
"It can be considered expensive, with a limited lifespan and support that eventually requires updating to newer solutions."
"The solution is neither too expensive nor very cheap."
"Price-wise, Fortinet FortiProxy is moderate - not the highest among competitors, but not cheap either."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"The pricing is fair based on its competitive market."
"It is costlier than other solutions."
"We have found the solution to be expensive."
"Zscaler is transparent about its pricing model."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."
"Price-wise, the tool is reasonable compared to the other products in the market but it is not a very low-priced tool. The solution does provide value for money."
