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.

Browser security has strengthened web DLP and protects unmanaged devices from data exfiltration
SD-WAN capability is another solution, and it is not Prisma Access Browser; we do not have SD-WAN capability with Prisma Access Browser. I would like to improve the private access to do the ZTNA. I think that Palo Alto has released the versions and integrated the private access in Prisma Access Browser, but I'm not sure. The feature that is missing in Prisma Access Browser is the capability to monitor the private access where a user can access a private app with authentication, posture, and granular access. Regarding the pricing aspect, many customers find that the solution is a little bit expensive. Palo Alto should reconsider the pricing as it is a bit expensive.

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

"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"iboss is among the few products providing inline filtering where no application is needed on the device. It operates on the network side and is not device-based. This feature was one of the main reasons why we stayed with them for so long."
"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"Technical support is pretty sharp and very responsive."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"The console is cloud-based, which is something I really appreciate."
"The security aspect of the solution, particularly the malware behind it, is excellent."
"Content filtering is the most useful feature of iboss."
"Prisma Access Browser improves security because the browser is one of the attack surfaces, it needs more security on the endpoint device and standardization of device usage, and it also helps standardize the access policy to the internet."
"Prisma Access Browser is the most capable, advanced, and flexible product."
"The most interesting use case that interests our customers is the DLP features on Prisma Access Browser; it is a great DLP solution with watermark and prevents data exfiltration."
"The most valuable feature of Zscaler Internet Access is that it is a consolidated solution, it comes with many features, such as DLP."
"The solution replaces multiple vendor technologies with one which makes it worth the cost."
"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."
"In terms of management and visibility, there is a single panel where you can configure the policies for your entire organisation worldwide."
"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 is an expensive solution, but it's worth the price."
"Zscaler Internet Access is less expensive than competitors like Palo Alto, offering a premium service justified by security enhancements and cost-effective scalability."
"I like the granularity of the control of all the traffic, including SSL inspection. I also like the fact that the user interface is intuitive. The latencies with Zscaler are minimal compared to those of any other competitor. Other competitors do not really have the global scale that Zscaler has and cannot promise low latencies."
 

Cons

"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"Sometimes, obviously, there are bugs."
"Their on-premise hardware's network interface is capped at one gigabit, which is sort of a problem. If you stand a filter up where all traffic flows through that, according to them, in order to go above a gigabit, you have to have multiple devices, which in today's IT seems a little bit silly. They could easily put in an SFP port into their device that could accommodate 10 gigs or at least offer a box."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"The reporting feature needs improvement."
"The area I would like to see improvement in is the ability within the reporter to navigate directly to the content the user is traversing."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"Regarding the pricing aspect, many customers find that the solution is a little bit expensive."
"The maturity of the product needs improvement as the implementation is very complex."
"In the beginning, the solution may not be very user-friendly and could be complex."
"Do not expect to pay for the service and start using it, like Gmail. Zscaler requires a proper implementation to be done to make it successful."
"The pricing is an issue. It is expensive if you have all of your users in the same location."
"The solution is expensive. They recently revised the pricing and packaging."
"It also needs better integration with other applications as well. There are some restrictions."
"One feature I am missing is the ability to connect automatically to internal monitoring systems."
"Zscaler Internet Access's troubleshooting is very limited, and their textbook logs need to be more informative."
"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 performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again."
 

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 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."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"It is probably in line with other solutions, but I do not deal with the financial side."
"The overall pricing for iboss is very competitive and transparent."
"It is expensive compared to one of its competitors."
Information not available

"Our monthly fee is around R3000."
