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 is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"The console is cloud-based, which is something I really appreciate."
"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"The security aspect of the solution, particularly the malware behind it, is excellent."
"Technical support is pretty sharp and very responsive."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"Its initial setup was straightforward."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"My advice to others looking into using Cisco Duo is that it is a great product, and I recommend it for everyone, specifically for those using Cisco Secure Client."
"The app has greater stability than rival solutions such as Google Authenticator, and Duo Push authentication is a valuable feature."
"The best feature Cisco Duo offers is its simplicity."
"Everybody loves it. They feel a sense of security when they get that prompt to send them a text, or an email."
"I appreciate the simple login feature of Cisco Duo; being able to log into your actual page and then having all your apps there is convenient."
"Duo has allowed us to add an additional layer of security to our organization and to establish trust for every access request and secures our environment."
"The most appealing feature of Cisco Duo is the phone notification system that simply pops up on your phone."
"What I appreciate the most is that you can push a notification with your phone and log in to your computer."
"It is a stable 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."
"The most valuable features of Zscaler Private Access are its ability to integrate with multiple IDPs and application segmentation."
"I find all Zscaler Private Access features valuable because each replaces flawed technologies, such as EPAs being replacements for VPN and PR as a replacement for PAM, so I can't mention only one valuable feature. Overall, Zscaler Private Access is a good solution."
"It does the job. What it is needed for. I can use it for VPN, I can use it for secure connections, I can use it as a firewall. So the solution does the job."
"What I find most valuable in Zscaler Private Access is that it's a VPN, and its connectivity as a VPN is its most valuable feature."
"The customer service and support are very good."
"The policies are very easy to implement."
 

Cons

"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."
"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."
"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"The dashboards for local use could be better."
"The dashboards for local use could be better."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"It is stable, but due to growth, it can sometimes be less stable than wanted."
"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."
"To improve Cisco Duo, the biggest consideration is the licensing standpoint; the most common issue I've found is customers not setting up the Active Directory sync properly, leading to inflated licensing usage when they try to delete inactive users that are still being charged."
"It is easy to use when logging in, but at times, there's a delay in getting the pop-up on a phone, requiring users to occasionally retry authentication depending on backend services."
"There are limitations because Cisco Duo does not support Hotmail accounts, which many people use to log in to their systems."
"I wouldn't mind seeing some options for remembering a device for a short period of time or a specific login, particularly for administrative engineering staff, as we may be logging in to four or five different services."
"Cisco Duo can be improved by exploring a way to make it a more seamless integration and by deploying an in-house server."
"The product could be more intuitive on the app."
"Conversational AI in Cisco Duo is limited in its current application."
"We were considering purchasing other products, like AMP for Endpoints, and it was not properly integrated with the firewall function. It might be better now with SecureX."
"The solution needs to improve a lot of aspects."
"From a user interface perspective, while the platform is powerful, the policy configuration and navigation can feel complex, especially for new users."
"We faced certain migration and implementation challenges in executing the tasks, so I would suggest improvement related to the stability of the solution."
"It's an expensive solution."
"What could be improved in Zscaler Private Access is its notification. For example, if there's a speed issue, there should be a pop-up that alerts the user about it. If there is a network quality issue, for example, it isn't good enough to connect to, or the network quality is bad, there should be a notification from the solution. Zscaler Private Access also needs improvement in terms of its interface and security."
"Zscaler Cloud DLP needs to improve its compatibility with other security tools."
"The pre-defined dictionaries could be improved."
"An area for improvement would be the ease of configuration."
 

Pricing and Cost Advice

"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."
"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."
"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."
"Its price is reasonable. It is not highly expensive."
"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."
"Price-wise, the solution has been very, very reasonable...Licensing is the last thing I think about Duo Security because it's so easy, and I had no problems with it."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"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."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"It falls in line with everything else."
"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."
"Zscaler Private Access can be an expensive solution, depending on the license type you will purchase."
"Zscaler CASB is an expensive solution."
"The product has reasonable pricing."
"Zscaler DLP solution is expensive, with a fixed pricing structure that is billed annually and monthly. There are no additional costs for licenses."
"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."
"The price is competitive."
"My company is a Zscaler Private Access partner, so the customers pay for the license fees."
