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.

Supports seamless authentication for users across multiple organizations and personal portals
The features I use in Cisco Duo include Duo Pushes to confirm my identity to the device, and eventually as MFA security was increased, I actually had to use exchange passcodes. Sometimes, I have to go into the site and get into Cisco Duo to retrieve the passcode, and many of them have been two-factor, where the sites send a passcode that I have to enter into Cisco Duo. It has been more of the latter. I have not seen issues with lagging or crashing on Cisco Duo's end; it was usually on the client end, often because someone set up a bad upgrade or there were connection issues with the Cisco Duo cloud through the administrative site.

Zero trust access has transformed remote connectivity and now simplifies secure app usage
Zscaler Zero Trust Exchange Platform, especially Zscaler Private Access, is very strong, though there are a few areas where improvements can be made. One challenge observed is around initial troubleshooting and visibility. While Zscaler Private Access provides logs, it can sometimes take time to pinpoint the exact cause of access issues, especially in complex environments with multiple policies and identity integration. Another area is the dependency on identity and connector health. Since Zscaler Private Access is heavily reliant on app connectors and identity providers, any issues with these components can impact user access, making proper monitoring critical. During the initial setup, policy configuration and application onboarding require careful planning, especially for larger environments with many applications. These challenges are manageable with proper design and monitoring. Overall, the platform delivers strong security and user experience. I would recommend a few improvements, especially around user interface, reporting, and troubleshooting experience. From a user interface perspective, while the platform is powerful, the policy configuration and navigation can feel complex, especially for new users. A more simplified and intuitive layout for policy mapping and application access would help reduce the learning curve. In terms of reporting, Zscaler Private Access provides logs, but having more built-in customizable dashboards and analytics would be very helpful. Better visibility into user access patterns, application performance, and real-time troubleshooting insights would improve operational efficiency. From a support and troubleshooting standpoint, it would be beneficial to have more granular centralized visibility, allowing for quick end-to-end tracing of a user request from authentication to application access without switching between multiple views. These improvements would make the platform even more efficient, especially for large-scale enterprise environments.

Quotes from Members

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

Pros

"iboss has significantly lowered the number of security incidents. It is crazy how much it blocks and how much it is aware of the outside danger."
"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."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"From a use-case scenario, what I like the most is the plug-in. I like the fact that we can do the filtering of these devices offsite independent of the network they are connected to, and we do not have to have traffic coming back inside our network."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"The console is cloud-based, which is something I really appreciate."
"It was a very easy product to install. It can be deployed very fast."
"The solution is easy to use."
"It is a great system regarding multi-factor authentication, specifically after we did the integration with Active Directory, allowing us to manage the users who use the VPN, our main gateway for VPN Cisco ASA Secure, with full administration."
"With respect to our users feeling safe, secure, supported, and included, Duo Security is among the best solutions that we have ever used."
"Another feature is the single pane of glass management. That's important for analytics and also for troubleshooting. It means there's one place that you go to at least start the troubleshooting process."
"The two-factor authentication is valuable because that is the use case for which we are using it."
"Duo Security improved my organization by helping us secure all access points within the company infrastructure."
"It is very easy for users to enroll, and there are a lot of insights that we get from using the app on devices that people use to authenticate."
"Cisco Duo helps minimize the risk of attack vectors and prevents unauthorized access to our data since it's tied with multi-factor authentication, which helps block threats."
"The solution is the best for storage."
"The solution is cloud-based with the latest inspection engines, which I find to be amazing."
"The UI is easy to use."
"The most valuable feature of Zscaler Private Access is we do not have to connect to a VPN, it is seamless. It is more convenient for us because we use one agent to cover the internet and VPN access."
"Its impressive scalability allows the combination of multiple dictionaries and using them as one engine, resulting in narrower data loss gaps."
"Zscaler Private Access is a platform that eliminates the complexity of VPN configuration."
"This is a product that I recommend for anybody who wants a scalable, cloud-based solution."
"The product's most valuable features are cloud-based services and secure internet access. We don't have to set up any physical appliances."
 

Cons

"The dashboards for local use could be better."
"The reporting feature needs improvement."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"Sometimes, obviously, there are bugs."
"It is stable, but due to growth, it can sometimes be less stable than wanted."
"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."
"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, and that is where in 2025 we had to migrate to the Palo Alto-based platform."
"Our iboss subscription access should be more secure with an OTP or VPN etc. It is easy to gain access if, for example, hackers obtain my username and password."
"Regarding the Premier licensing, it is a little bit pricey, but it is in the market range with the competitors."
"For upgrades, there should be a better notification of when they're coming out. We always have a testing phase, so we need to be ahead of it. It takes us longer before we can upgrade to the newest version."
"My experience with Cisco Duo's strong security authentication system is that sometimes there are difficulties, and sometimes users just won't be able to log in. We have to reset their password so they can use Duo."
"There could be improvements made to the dashboards and more integration with the rest of the Cisco ecosystem."
"Often, people do not receive expiration messages, and sometimes, for security reasons, accounts get disabled without notifying the end user, so they mistakenly think something has gone wrong when it really just needs to be re-enabled on the external system."
"While two-factor authentication with mobile devices provides a high level of security, it's still not foolproof, as someone could potentially steal your phone. It would be beneficial to have information about the authentication location."
"Cisco Duo is a modern product that does not support older applications, lacking backward compatibility. It should work on supporting legacy applications and legacy approaches."
"Cisco Duo can be improved with better ways to set users up. Currently, we might not be doing it perfectly as we're having them email in phone numbers to get them set up with Duo Mobile."
"There are latency issues with the solution. They are small, however, they are there when you compare it to other vendors."
"The pricing for Private Access seems to be on the expensive side, and I believe they should consider making it more competitive with other solutions."
"The only issue with Zscaler Cloud DLP is that it only gives you DLP protection from web traffic, which is flowing out, while a full-blown DLP solution such as Forcepoint or Symantec gives you DLP coverage for multiple channels."
"I rate it a seven because I am still working through some kinks from a performance and a support perspective."
"The DX layer could be better if it had improved visibility."
"We have issues with the tool's maintenance and networking. It should be able to work in offline mode as well."
"The menu for the ZIA portal could be organized a little bit differently. The most-used modules should be at the top of the menus, not somewhere near the bottom, some of them are not organized well in my opinion."
"The tool must provide IP-blocking features."
 

Pricing and Cost Advice

"We have not priced the solution recently, but they were competitive with other vendors in the past."
"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."
"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."
"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 expensive compared to one of its competitors."
"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."
"You pay per user when using this solution and the pricing is fair."
"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"The product’s pricing is reasonable."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"It's a bit confusing because we're on a three-year plan with a certain number of licenses, and we've gone over that number. They told us that when we renew, they will add all these licenses. We've expanded quickly, so everyone's kind of scared because no one knows what the bill is with the long pricing cycle."
"The pricing was a lot more than what we were paying for our previous solution."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"In terms of market positioning, I would describe Zscaler Private Access as offering optimal pricing. Based on our experience, Cato Networks tends to be slightly more expensive."
"The product is a bit expensive."
"There is definitely an ROI."
"As per industry leads, Zscaler CASB is an expensive solution."
"Zscaler CASB is an expensive solution."
"Zscaler Private Access is extremely expensive."
"The pricing is expensive and on the higher end. Honestly, in my opinion, it is not worth the price."
"Zscaler Cloud DLP is moderately priced. We pay around 2 million rupees per year."
