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

"This product is solid, fairly easy to use, and reliable."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"Technical support is pretty sharp and very responsive."
"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 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."
"The security aspect of the solution, particularly the malware behind it, is excellent."
"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"iboss is among the few products providing inline filtering where no application is needed on the device."
"Cisco Duo is very user-friendly."
"It's a great solution for securing access to the applications and network because we can integrate the solution with all types of applications."
"Duo Security provides a high level of certainty regarding the identity of the individual performing an action. Whether it's logging into a system, using VPN, or utilizing Autopay, establishing that trust is crucial. I can't imagine any security company, organization, or IT team that wouldn't prioritize having multifactor authentication enabled when accessing critical systems."
"Cisco is the perfect product for our current size, and I don't think we'll have problems with scalability as we grow."
"The feature of Cisco Duo that I prefer the most is the policies, being able to control what we need to within the policies."
"The thing that I appreciate the most about Cisco Duo is the ease of setup."
"Overall, it provides functionality and security with the two-factor authentication, enabling us to mitigate rogue access requests to our network and giving our workers the ability to work hybridly and tackle day-to-day jobs securely without having to come into the office."
"Multifactor authentication and secure two-factor authentication are the most valuable features. It's been around for a while, but now it's becoming an enforced behavior as opposed to something that you used to do as optional."
"Overall, the solution does a pretty good job at web filtering."
"The most valuable features of Zscaler Private Access are reliability, scalability, and availability."
"The most valuable feature is its ability to establish connectivity for remote users and remote endpoints. It offers a high level of granularity compared to typical VPNs, which also encapsulate a lot of I/O."
"The customer service and support are very good."
"I like the web filtering capabilities, which are very good, and it offers sound internet security notifications with a stable, scalable solution and an easy-to-use user interface."
"Sandboxing, DLP, and SSL inspection engine are the most valuable features of Zscaler SASE."
"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."
"The most valuable features of Zscaler Private Access are its ability to integrate with multiple IDPs and application segmentation."
 

Cons

"The endpoint-type solution is an area that needs some improvement."
"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."
"The dashboards for local use could be better."
"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."
"I am currently doing a PoC of the zero trust aspect of it. Compared to other similar solutions, it is hard to get around each feature. It takes a while to get used to it."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"SSL decryption: We had issues with learners using apps instead of using web browsers."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"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."
"The deployment experience was more difficult than we expected because we had some problems with the version of the OS that we have in our servers."
"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."
"We have users who move throughout the world, and their levels of connectivity change. It can be a challenge, if someone is in Bahrain, to authenticate via Duo."
"One area that might be improved is that setting up SMS texting is not as easy as using the app, even though it does support it."
"Integration between Duo Security and FTDs needs improvement. Integrating Next Generation Firewall safety with Duo Security currently requires a proxy agent between Active Directory and the appliance. It's an additional factor that we need to think about. It would be great to have direct integration with FTD so that we don't have to worry about middleware products. For the rest of the Cisco Secure solutions, the APIs need improvement."
"Duo Security should have more customized use cases. For example, if a client needs to have more customization, it would be better to connect directly with Duo's R&D to try to discuss the issues together in order to add customizations."
"The only challenge is finding the right person sometimes. From what I've seen, being a named account is a big deal."
"There are some performance issues with the solution once the module addition begins"
"The connectivity monitoring part should be included in the core license without any extra charges."
"The interface needs a bit of work."
"I rate it a seven because I am still working through some kinks from a performance and a support perspective."
"Zscaler Private Access's reporting is poor. We should have more insight into the reports regarding what is blocked and allowed."
"Users report application access or latency issues with Zscaler Private Access."
"Zscaler Zero Trust Exchange Platform probably needs to be more efficient because scanning takes a lot of time. Some vulnerabilities create issues, and when we wanted to identify the source of the vulnerabilities, specifically focusing on mobile ID and related areas, it was unable to provide assistance."
"They should work on a replica account. There could be alerts and replica files sent to the DLP team during data collection."
 

Pricing and Cost Advice

"It is probably in line with other solutions, but I do not deal with the financial side."
"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."
"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."
"I rate the product pricing a seven out of ten."
"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 is pretty competitive. It's pretty cheap. Anybody can adopt it."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"It falls in line with everything else."
"Cisco's licensing is always a bit complicated to understand, but the price is fair. It could be more expensive than others, but the way they integrate everything, it has a fair price."
"The pricing was a lot more than what we were paying for our previous solution."
"In the long run, cloud services are not inherently costly."
"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 cost is expensive. It depends on the number of users."
"As per industry leads, Zscaler CASB is an expensive solution."
"It is an auto-renewal subscription service."
"It's expensive currently. But when purchasing for a large number of users, there's room to negotiate. It's really up to the procurement team."
"The solution has increased prices this year."
"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."
