Executive SummaryUpdated on Jun 3, 2026

Zscaler Internet Access (ZIA) and Fortinet FortiProxy are key competitors in the cybersecurity industry, particularly in internet access security solutions. ZIA appears to have the upper hand due to its comprehensive security features and low latency global server access, whereas Fortinet is favored for its affordability and granular policy controls.

Features: Zscaler Internet Access offers secure web gateways, data loss prevention, and cloud access security broker (CASB) capabilities. Its cloud-native approach also provides low-latency global server access, making it scalable and reliable. Fortinet FortiProxy focuses on user-friendly attributes, detailed access policies, and DNS filtering, ensuring compliance with security protocols while offering visibility into user behavior.

Room for Improvement: Zscaler could enhance user and role-based access integration and improve local data center availability in specific regions. Fortinet requires improvement in its web filtering capabilities and could benefit from an intrusion prevention system. Its documentation and remote support services also need enhancements. Both products need stronger AI/ML integration and more adaptable pricing models.

Ease of Deployment and Customer Service: Zscaler supports versatile deployment models across public, private, and hybrid cloud environments. However, it faces mixed reviews regarding customer service response times. Fortinet FortiProxy is primarily on-premises, with deployment considered straightforward and support being reliable, albeit sometimes needing clearer scheduling and direct vendor intervention.

Pricing and ROI: Zscaler Internet Access is known for higher costs but justified by robust security features and scalable cost efficiency, yielding good ROI for larger enterprises. Its pricing is considered steep for smaller businesses. Fortinet FortiProxy is budget-friendly, offering effective features for moderate needs, thus being more cost-effective for smaller-scale implementations.

Cloud gateway has strengthened remote web security and now needs better Mac and ISP support

The problem our organization had is that iboss failed for the Mac devices. It is not able to give a successful agent for the Mac agents. That is where in 2025, we had to migrate to the Palo Alto-based platform. If your use case is for just Windows laptops,you can consider this platform as an option One issue is the data center resiliency part. In India especially, they are not tied up with the Tier 1 ISPs like Tata or Airtel; they were having Tier 2 ISPs and encountered many issues reaching few major sites that my organization depends on, and they were having problems that they could not fix quickly. They also lack a mechanism to route that traffic within their data center; rather, they ask customers to make a pac file change to route it to Singapore explicitly. It would be better if they route from their backend , i mean even if I send it to India DC, they should be able to route it internally to make that work; however, they fail to do that and ask the customer to route it in the pac file. Another suggestion is that in China, they do not have the proper setup; they used to have numerous problems with slowness and lack of premium circuits in China as well. That leads to multiple sites working slowly with latency-related issues. So the main issue is the ISP-related problems that need to be solved.

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

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."

"The iboss solution gives me the ability to scan the traffic through all the ports, through all the 131,000 PCP and UDP ports, and with this ability, we have the granularity also for consults over social media and applications on mobile, and this is an advantage that the customers are looking for right now."

"We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times."

"The console is cloud-based, which is something I really appreciate."

"From a corporate perspective, I understand that it's important to keep the company data safe."

"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."

"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."

"iboss is definitely very good in terms of service."

More iboss pros

"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."

"I liked the tool's ability to provide detailed access control. For example, we could allow users to watch YouTube videos but not post comments. This level of control wasn't available in FortiGate."

"It is a really stable solution."

"It seamlessly integrates with various security products, enhancing threat intelligence and improving indicators of compromise."

"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."

"We can use Fortinet FortiProxy configuration for your network."

"The tool's most valuable feature is traffic inspections."

More Fortinet FortiProxy pros

"The solution has reduced cyberattacks."

"Zscaler Internet Access protects using data loss prevention. If you have a CASB exposing your cloud out into the network, then Zscaler Internet Access will go ahead and control that unknown cloud application in the CASB, protecting it. There is also data detection with exact data match. This improves the data coming into your cloud so you are protecting it."

"Zscaler Internet Access has positively impacted my organization by reducing the dependency on on-premises hardware and improving security posture, enabling faster user onboarding, and providing better performance for remote users."

"Zscaler Internet Access is very scalable, and requests for scalable solutions are met quickly."

"Having a centralized firewall that protects the whole topography is quite awesome when you also have users that are not on the plan because it actually improves visibility of those users."

"It is easy to set up the solution."

"The solution’s customer service is good."

"We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."

More Zscaler Internet Access pros

Cons

"Sometimes, obviously, there are bugs."

"To scale up, a new iboss Node Blade Chassis must be purchased."

"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."

"I have heard they are doing DDoS filtering, but I am not certain if they are implementing it correctly."

"The reporting feature needs improvement."

"iboss can be improved because the integration could be better; you need to import all the sites that you access today, and there are a few problems whenever you import thousands of websites, making the integration process messy for the users."

"Its pricing could be better."

"One thing I would like to see differently with their Zero Trust platform is that some of the AI aspects related to high-risk activities have more false positives."

More iboss cons

"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."

"Its power supply process for some of the proxies needs improvement."

"I see that the solution's interface is not in French...It would be good for our company if we could have the tool interface in French."

"Fortinet FortiProxy should improve by adding more documentation and guides."

"Its web filtering capabilities could be improved."

"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."

"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."

"It is quite expensive. It does its job, but it is quite expensive for what we need."

"They block Zscaler IPs when the traffic origin is from Zscaler IPs. They've been blocked by certain government organizations so the end users are not able to visit those websites unless we ask them to unblock those IP. This is a bit problematic."

"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."

"The admin console needs improvement as it loads slowly and sometimes takes two to five minutes to open."

"The pricing is an issue. It is expensive if you have all of your users in the same location. It is expensive compared to other firewalls on the market."

"When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. "

"The admin UI and documentation for Zscaler Internet Access could be more intuitive for new users, specifically during initial rollout and advanced policy design."

"Sometimes it's not easy to use during large deployments of workstations. It's a bottleneck from a network point of view."

More Zscaler Internet Access cons

"We have not priced the solution recently, but they were competitive with other vendors in the past."
