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

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"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."
"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"As I mentioned, the return on investment is significant, as it saved our office locations' bandwidth because when you are working remotely at home, your internet traffic routes directly to iboss and will not go to your office building, saving bandwidth bottlenecks and ensuring that issues with our building internet circuits will not impact your internet connectivity because you are directly going to the iboss data center."
"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"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."
"Technical support is pretty sharp and very responsive."
"Duo Security just adds another layer; it's a great addition to the security of any network infrastructure."
"Cisco Duo benefits my organization by making it easy for me to reach out to customers using Cisco Duo so they can integrate on my platform using their credentials."
"What I most appreciate about Cisco Duo is the ease of use."
"My overall rating for the solution is ten out of ten."
"The two-factor authentication is valuable because that is the use case for which we are using it."
"Cisco Duo benefits the company by increasing the security footprint, and it is easy to manage users, disable users, or bypass if needed in case of an emergency."
"It is very easy. Having just wrapped up my tenure at Cisco, it was used day in and day out for security. It was always easy to log in and not have to worry about logging in multiple times."
"The flexibility is the most valuable feature. We use it for the app on the phone. When we're at different locations, the phone is usually there, so we can use that. It has just been a very flexible option."
"Has a good zero trust feature."
"I would recommend Zscaler Cloud DLP to others because it's the best proxy product in the market at the moment."
"The agent's versatility is notable, used for digital experience monitoring to collect valuable endpoint metrics for troubleshooting."
"I like its ease of use; it has a single pane of glass for the ZIA and ZPA pieces, is very manageable, is very easy to deploy for secure access, and gives half-decent coverage for visibility in terms of what the users use and what data is being proxied through the access gateway."
"The best feature is the ability to establish the connection between your public network and automatically connect to the intranet connection."
"From a cost perspective, I would say fair market value, and then from an efficiency perspective, I notice a very good user experience, which is easy to use with Zscaler Zero Trust Exchange Platform."
"It has been helpful in maintaining our infrastructure. The granular level control it offers allows us to set application policies per application for each user."
"It is easy to use."
 

Cons

"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"The endpoint-type solution is an area that needs some 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."
"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."
"SSL decryption: We had issues with learners using apps instead of using web browsers. This type of encryption is tough for any appliance in a BYOD environment."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"File integrity monitoring would be very advantageous as an additional feature."
"I have not seen ROI with Cisco Duo; probably the opposite, because it impedes productivity time to be able to get into the system. You have to authenticate and do your regular login and your Active Directory logins."
"I believe Cisco Duo needs to be improved on the delay process because there is a delay when we send a Duo Push or when we are signing into any applications."
"Improving Cisco Duo might involve alerting us about telephony credits when people receive texts. We hit zero at one point, and we were running around in circles without any idea until I discovered it."
"I think we'd need more experience to learn Cisco Duo because we're just at the beginning of using it."
"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. I wish there was more of a self-service option than there is currently, at least to my understanding of Duo."
"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."
"An improvement for Cisco Duo would be a simplification of the licensing model since it's quite complicated to know what's included or not, especially now as it's part of Cisco Secure User Suite, and there are many modifications happening regarding the licensing."
"We had a lot of trouble configuring the password reset function, and as a result we now have a second channel that bypasses Duo to allow users to reset their password."
"We faced certain migration and implementation challenges in executing the tasks, so I would suggest improvement related to the stability of the solution."
"Price-wise, it is a costly product and it should be reduced."
"The interface needs a bit of work."
"It's an expensive solution."
"In the next release, I would like to see RE2 Regex supported."
"There is improvement in enhancing proper manageability, policies, and logs. So, log management could be improved."
"While Zscaler supports client-initiated connections, it does not support server-initiated connections. This is a feature that Zscaler may consider adding in the future."
"We would like to extend the SASE applications for Zscaler."
 

Pricing and Cost Advice

"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 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 expensive compared to one of its competitors."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"The pricing is pretty competitive. It's pretty cheap. Anybody can adopt it."
"It has a fair pricing model. I know they have different tiers, but it would be nice to have different types of licenses for certain groups of users in our organization. That way, we wouldn't have to lump everybody into one group. That would be also one complaint."
"The pricing was a lot more than what we were paying for our previous solution."
"My experience with pricing, setup costs, and licensing has been good, with no issues. I am pleased that the prices remained stable after Cisco acquired the solution."
"The licensing is very good because it does not cost a lot of money. It's affordable for all-sized customers, including enterprises. There is an additional cost for premium support."
"With regard to pricing, for a small business buying a one off, it's pretty expensive. If it's an enterprise that has thousands of employees, however, it's really nothing to protect your data because if your network goes down or it's breached, you're losing millions of dollars every minute. When it comes to a large enterprise, it's priced where it should be because you're talking business to business. You're not talking business to consumer."
"It was very reasonable."
"It is affordable for what's coming to the table with it, but in this day and age, the cost is looked at under a microscope, and companies need to very finely define what is needed versus what is critical. In some cases, it might not be cost-effective for a company to have it. In a lot of other cases, it is the cost of doing business."
"It has been relatively reasonable for what it does. Some of the additional license costs based on the advanced next-generation firewall functions are quite high, and they should have certain features ready and available as a baseline rather than having to purchase additional licenses for it. Overall, the cost seems reasonable."
"It's an affordable solution"
"Zscaler CASB is an expensive solution."
"The product is a little more expensive than other tools."
"It is an auto-renewal subscription service."
"The licensing model for Zscaler Cloud DLP allows you to only buy what you need. You don't need to buy it as a whole, so it's good."
"My company is a Zscaler Private Access partner, so the customers pay for the license fees."
"As per industry leads, Zscaler CASB is an expensive solution."
