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

"Valuable features: Within the filter: Controls (Web categories, applications, and Allow/Block list) and Network (local Subnets). Within the reporter: Logs (Event Log) and Reports."
"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."
"The security aspect of the solution, particularly the malware behind it, is excellent."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"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."
"This product is solid, fairly easy to use, and reliable."
"The iboss solution gives me the ability to scan the traffic through all the ports, through all the 131,000 PCP and UDP ports, and with this ability, we have the granularity also for consults over social media and applications on mobile, and this is an advantage that the customers are looking for right now."
"My overall rating for the solution is ten out of ten."
"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."
"Cisco Duo seems very scalable—in my experience, I started with a small-medium business, and in my last contracting position, it was a large one for a major worldwide airline that had hundreds of thousands of devices that could use Cisco Duo, and it scaled very well."
"The app has greater stability than rival solutions such as Google Authenticator, and Duo Push authentication is a valuable feature."
"It is a good solution for hybrid environments and VPN."
"Duo offers dual-factor authentication for our logins; I put in my credentials and hit go, then I get an alert on my Apple Watch and approve it, and that part is just phenomenal."
"Cisco Duo is quick to deploy and easy to start."
"Cisco Duo has strengthened the ability to defend against both phishing and identity-based attacks."
"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."
"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."
"I would recommend Zscaler Cloud DLP to others because it's the best proxy product in the market at the moment."
"The customer service and support are very good."
"It is a stable solution."
"Before Zscaler, we used to use a lot of other products, however, when we were introduced to Zscaler we became confident it could meet the use cases."
"The solution offers a simplified network infrastructure and security functions and it enables secure remote access for the users"
"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."
 

Cons

"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, obviously, there are bugs."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"File integrity monitoring would be very advantageous as an additional feature."
"One thing I would like to see differently with their Zero Trust platform is that some of the AI aspects related to high-risk activities have more false positives."
"The endpoint-type solution is an area that needs some improvement."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"It could be a little bit more intuitive when it comes to the sign-up process. I know they send out an email, but sometimes our users get a little confused. It could be an end-user problem, but Cisco could work on that a little."
"The product could be more intuitive on the app."
"Cisco Duo is stable, but occasionally there are emails about incidents that affect some services temporarily."
"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."
"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 think the prices of Cisco Duo are quite fair, but the main problem is that Microsoft Authenticator is built-in with Microsoft 365, so everyone is switching to that and not using Cisco Duo because it is a standalone product that costs extra, despite the price being fair."
"The only thing I can think of to improve for tech support is to have a dedicated engineer but then I would get an engineer that has priorities in one area or another and maybe not the scope I need."
"Reducing or eliminating the "telephony credits" system used by Duo would be great."
"I can't speak to any missing features."
"In the next release, I would like to see RE2 Regex supported."
"The product must allow users to check logs for an entire year in the local console."
"Price-wise, it is a costly product and it should be reduced."
"Those folks will likely have some issues."
"Users report application access or latency issues with Zscaler Private Access."
"Conflicts arise if you do not have the same management teams on the product."
"We would like to extend the SASE applications for Zscaler."
 

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."
"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."
"The overall pricing for iboss is very competitive and transparent."
"It is probably in line with other solutions, but I do not deal with the financial side."
"It is expensive compared to one of its competitors."
"My experience with the pricing, setup cost, and licensing of Cisco Duo has been great. We've been there for 10 years. While we haven't gone through the setup part for a while, licensing is straightforward and convenient for higher education because student populations are included. So, we don't have to pay extra for it. We just pay for our knowledge workers, which has been great, and the cost is reasonable."
"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."
"From a reseller perspective, it's still challenging to explain the whole license strategy to a client, so we really have to be ahead of that for all the true forward conversations."
"I rate the product pricing a seven out of ten."
"The pricing is pretty competitive. It's pretty cheap. Anybody can adopt it."
"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."
"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."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"Zscaler DLP solution is expensive, with a fixed pricing structure that is billed annually and monthly. There are no additional costs for licenses."
"The solution is expensive."
"It is an auto-renewal subscription service."
"The product is a bit expensive."
"The price is competitive."
"The solution has increased prices this year."
"The product has reasonable pricing."
"As per industry leads, Zscaler CASB is an expensive solution."
