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 solution has massively improved our security posture, giving us full visibility into what our staff does online."

"The security aspect of the solution, particularly the malware behind it, is excellent."

"The iboss system is highly reliable. The false positive rates are small compared to some other systems we've experienced through other partner agencies who use competing solutions."

"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."

"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."

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

"iboss is easy to use despite its complexity. Multiple engineers manage it, but it's significantly more straightforward to administer than traditional VPNs and web proxies."

"Granular setup, which was able to set different levels of filters using the OUs in the AD."

More iboss pros

"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."

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

"We have seen an ROI; this is a well published product, and you get value for your money."

"The solution is scalable and stable."

"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."

"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."

"Tech support is good."

"Stability-wise, I rate the solution a nine and a half out of ten...The setup phase was easy."

"Zscalar Internet Access is for Internet security, like an Internet security gateway. I like how it runs seamlessly in the background with a single sign-on. The controls you can have on devices for Internet security are good, and it doesn't impact speed wherever you're connected. Overall, I think it's very good so far."

More Zscaler Internet Access pros

Cons

"Fold that in with the risk intelligence they're getting from all of the different subscriptions they are a part of. Now, these security companies subscribe to things like emerging threats, databases, etc. You can fold all this intelligence to decide what's happening on an endpoint. I would love to see them start moving into that space. That would compete directly with Microsoft. Maybe that's why they haven't. Having that ability native within the solution would be great. The other area in which I would love to see improvement is more detailed descriptions of why they block websites."

"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."

"It is stable, but due to growth, it can sometimes be less stable than wanted."

"I'd like to see them accelerate development on the security side, particularly around data loss prevention."

"The reporting feature needs improvement. It doesn't give you the expected results. It is quite difficult to get the specific reports needed, and it is not as intuitive as the rest of the platform."

"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."

"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."

"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."

More iboss cons

"The solution's logging system should be improved because its logs are not precise and are a little confusing."

"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."

"In Sangfor Internet Access Gateway (IAG), its speed is an area of concern where improvements are required."

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

"The tool should improve the predefined dictionaries."

"For the stability of Zscaler Internet Access, I would recommend it, but for the price, I think it's too expensive."

"One thing that needs to be improved is their presence in China. I'm not sure if that's a Zscaler thing or if it's a problem with all vendors in this space, but it would be nice to have better coverage in China. This concern is a common one for vendors across the board when dealing with the Chinese market."

"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."

"I would like to see more training and video documentation."

"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."

"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."

Pricing and Cost Advice

"The overall pricing for iboss is very competitive and transparent."

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

"It is expensive compared to one of its competitors."

"It is probably in line with other solutions, but I do not deal with the financial side."

"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 not expensive, and it is also not cheap. iboss is priced right in the sweet spot for the number of features it offers."

"I rate the product pricing a five or six out of ten on a scale of one to ten."

"The solution’s pricing is cheaper than any other solution."

"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."

"It is a few pounds per user per month."

"The pricing for Zscaler Internet Access could be made cheaper."

"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."

"Our monthly fee is around R3000."

"We have found the solution to be expensive."

"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."

"Zscaler is an expensive solution, but it's worth the price. Their services are unmatched by competitors. Some may come with half the features that Zscaler can offer and be much cheaper. However, they do not have the global coverage that Zscaler has, and they will not provide the same low latencies and the same speeds that Zscaler can."

"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
