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.

Designed to provide comprehensive and secure internet access with high visibility into users
After my purchase, I noticed a need for improvements, particularly in the area of identifying the source user of the device, which can sometimes roll back to the base. Additionally, there were challenges with SSL gate traffic, which wasn't functioning as effectively as expected. Even though there have been fixes to these issues, they should be inherent to the product and need further attention. These aspects, especially sub-features, aren't very robust and seem complex. Regarding integration, while Sangfor Internet Access Gateway (IAG) integrates well with its own products, its compatibility with third-party tools like QB is limited. There's room for improvement in making protocols compatible with various third-party products.

Cloud security has transformed remote access and now supports zero trust for all users
The best features Zscaler Internet Access offers are Secure Web Gateway, URL filtering, SSL inspections, and policy-based access control. I find myself relying on Secure Web Gateway, URL filtering, SSL inspection, and policy-based access control the most because these are the main and top-most features I use regularly. Zscaler Internet Access has all of these types of features for securing all internet access and web inspections, allowing me to control all traffic through these features. Zscaler Internet Access features include a Secure Web Gateway for URL filtering, file type control, and inline SSL inspections. The second feature is a cloud firewall with Layer 3 to Layer 7 filtering control and stateful inspections. No hardware inspection or hardware firewall is required. I can also perform segmentations by users, location, and application. There is a cloud CASB solution available as well. Additionally, there is an advanced threat protection feature with signature-based behavioral detections, inline IPS, and zero-day threat protections. The cloud sandboxing solution scans unknown files and provides machine learning-based verdicts to prevent zero-day malware delivery in my environment. There is also a DNS security feature that provides DNS tunneling detections, malicious domain controls, and faster threat containment at the DNS layer. The data protection feature includes inline DLP and CASB-style cloud app control, data sovereignty enforcement, and browser isolation, which executes risky sites in isolated cloud browsers and prevents endpoint compromises. 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. It has resulted in a drop in security incidents related to web threats and improved visibility into user activity. An area for improvement includes fine-grained troubleshooting tools, better policy simulations, and optimizations around initial configuration complexity.

Quotes from Members

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

Pros

"The security aspect of the solution, particularly the malware behind it, is excellent. That's something that really helped us out. It's not just a simple proxy that just blocks the insights of potential threats that come on behind it. They do malware detection and that helps us a lot."
"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"Its initial setup was straightforward."
"Valuable features: Within the filter: Controls (Web categories, applications, and Allow/Block list) and Network (local Subnets). Within the reporter: Logs (Event Log) and Reports."
"Technical support is pretty sharp and very responsive."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"I would say iboss is a very good product; its scalability is very good, and it's seamless for the user."
"The solution is interoperable and has centralized management."
"The most significant aspect is the control it offers over internet traffic, like managing computer access to specific sites such as Facebook. I find particular value in its ability to control the depth of internal traffic, enabling actions like blocking specific file extensions on social media or specific IPs. This control by categories is a standout feature for us in Sangfor Internet Access Gateway (IAG)."
"Stability-wise, I rate the solution a ten out of ten."
"The solution replaces multiple vendor technologies with one which makes it worth the cost."
"The solution is stable."
"Zscaler excels in security protection and the cloud is always up-to-date. It does not matter if you are a small or big organisation, you will receive the same security quality."
"Overall, we're very happy with our product."
"Zscaler covers all the features needed to replace a VPN or proxy solution; they are good, and they've been on the market for 15 years now, so they are mature enough."
"The protection is most valuable."
"Basically, the standard traditional model of a firewall becomes obsolete when you implement Zscaler."
"One on the main benefits is protection all time from anywhere."
 

Cons

"I appreciate that iboss's single pane of glass console gives centralized visibility into web traffic, user activity, security policies, and alerts from one dashboard, allowing us to quickly investigate incidents and monitor policy violations without switching between multiple tools, improving operational efficiency; however, the dashboard customization and reporting could be more flexible."
"Sometimes, obviously, there are bugs."
"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."
"The area I would like to see improvement in is the ability with in the reporter to navigate directly to the content the user is traversing. It is kind of there, but it's not perfect. Quite frequently, I receive links that lead me to pages with error messages."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"I would like to see simpler dashboards, more detailed reporting, and faster performance in iboss."
"Sometimes when you call in support, you get someone who is just following a sheet. It feels like a runaround. You feel that you are running into that support wall."
"File integrity monitoring would be very advantageous as an additional feature."
"After my purchase, I noticed a need for improvements, particularly in the area of identifying the source user of the device, which can sometimes roll back to the base. Additionally, there were challenges with SSL gate traffic, which wasn't functioning as effectively as expected. Even though there have been fixes to these issues, they should be inherent to the product and need further attention. These aspects, especially sub-features, aren't very robust and seem complex. Regarding integration, while Sangfor Internet Access Gateway (IAG) integrates well with their own products, its compatibility with third-party tools like QB is limited. There's room for improvement in making protocols compatible with various third-party products."
"The solution's logging system should be improved because its logs are not precise and are a little confusing."
"In Sangfor Internet Access Gateway (IAG), its speed is an area of concern where improvements are required."
"Zscaler should continue to make the user interface better. They should also improve the backup network and continue to expand it so that it can handle larger numbers of customers."
"The solution is quite expensive. It's around double what others are offering."
"Zscaler Internet Access's troubleshooting is very limited, and their textbook logs need to be more informative."
"I don't know whether it's Zscaler or not, however, sometimes I can't access my time management. I need to wait and try again a few hours later. Typically, if I let some time pass, I can access it again."
"An improvement would be if they could provide an out-of-the-box experience, like 20 to 30 features all ready to go. In comparison, LogRhythm offers out-of-the-box features. With Zscaler Internet Access, there is firewall IPS, multiple security services, filtering, DLP, and CASB browser isolation. These are things that all users are going to be using. However, when an administrator or architect would start building this, I would definitely need to engage professional services to help clients do it."
"We did hit a problem a while back where they didn't scale properly and we had some major issues."
"The reporting functionality could be a bit easier to use. There is a reporting function, but it's quite hard to do any good reporting, from a user-management perspective. For example, if a department manager wants to know how his department is using the web, there is a way to get the data, but it's quite cumbersome to get it and show it well. And that's true for comparing between departments."
"Zscaler does not provide dedicated IPs to each customer. Hence, they share a pool of IPs provided by Zscaler. There is a chance of blacklisting these IPs. I also do not like the multi-management portal."
 

Pricing and Cost Advice

"It is not expensive, and it is also not cheap. iboss is priced right in the sweet spot for the number of features it offers."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"The overall pricing for iboss is very competitive and transparent."
"We had the cost of purchasing a new appliance along with the implementation and licensing costs. However, the following year, the cost of just licensing was similar to what was paid the previous year for a new appliance along with the implementation and licensing costs."
"It is probably in line with other solutions, but I do not deal with the financial side."
"It is expensive compared to one of its competitors."
"I rate the product pricing a five or six out of ten on a scale of one to ten."
"It is one of the reason for choosing it over other available products. However, recently, this year, there have been recurring concerns. I believe we might consider migrating to another solution."
"The solution’s pricing is cheaper than any other solution."
"Licenses are available on a per-host basis. Some features like sandboxing require an additional fee, but most standard features are included in the license."
"The tool is moderately priced."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"It is costlier than other solutions."
"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."
"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
"If we need any extra features, the price will increase."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
