Executive SummaryUpdated on Feb 8, 2026

Cisco Duo and Zscaler Zero Trust Exchange Platform compete in the cybersecurity space, each offering unique features and services to enhance network security. Based on the comparisons, Cisco Duo takes an edge with its ease of deployment and customer service, whereas Zscaler's strength lies in integration and connectivity features.

Features: Cisco Duo offers multi-factor authentication (MFA) with options beyond smartphones, making it flexible for all users. Its cloud-based management supports VPN security through a single-pane-of-glass interface. For Zscaler, its Zero Trust Exchange Platform excels with seamless VPN-centric connectivity, security features like Data Loss Prevention (DLP) and Cloud Access Security Broker (CASB), and easy cloud integration.

Room for Improvement: Cisco Duo could improve by removing the telephony credits system and extending on-premises support. Compatibility with additional products would also enhance its offering.

Enhances web security with a single pane of glass and flexible deployment

I don't see any need for improvement; one of the really good things about iboss as a company is that they listen to customer feedback. I have suggested enhancements, and they are responsive, making changes for the better, and they do a lot of testing. To improve iboss, although we haven't used it, we considered the VPN solution that comes with the highest tier licensing, which includes DLP and various other add-ons. We prefer using another product which automatically logs you back onto your network when turning on your PC. With iboss, the connection is manual, which doesn't meet our needs. Additionally, sizing can be tricky because, although the initial recommendations may seem adequate, actual usage may require more gateways than anticipated.

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 among the few products providing inline filtering where no application is needed on the device."

"Its initial setup was straightforward."

"Granular setup, which was able to set different levels of filters using the OUs in the AD."

"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."

"We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times."

"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."

"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."

More iboss pros

"The UI of Cisco Duo is easy to use, especially the web backend, and it's really intuitive and easy to set up."

"It meets our security needs very well. It is easy to use, and documentation is also available. It is also very stable and scalable, and its support is also very good. We are satisfied with this solution."

"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."

"As a former employee, I think it's top-notch when it comes to protecting internal and external threats and preventing unauthorized access to the network."

"For me and my customers, the best feature is that it's very easy to integrate with the existing infrastructure. It takes a few minutes to configure it."

"It has definitely made our company more secure."

"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."

"Regarding the valuable features, I would say that Duo Security is easy to use, has speed, and is dependable."

More Cisco Duo pros

"It is a very scalable solution. Scalability-wise, I rate the solution a ten out of ten."

"Zscaler Cloud DLP provides you with basic DLP features that you get out of the box such as keywords, regular expressions, and data identifiers, for example, your social security numbers, and credit card numbers, with everything built into the product, so you can directly use those features within the policies. You don't need to create it from scratch, and to me, this is the biggest benefit of Zscaler Cloud DLP. You have a lot of templates to choose from in the solution, rather than having to create templates from scratch or reinvent templates."

"The solution is cloud-based with the latest inspection engines, which I find to be amazing."

"This is a very good and stable solution that has all the requirements for your security solutions."

"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 most valuable features of Zscaler SASE include web filtering, application control, and the private access configuration."

"The agent's versatility is notable, used for digital experience monitoring to collect valuable endpoint metrics for troubleshooting."

"The product's most valuable features are cloud-based services and secure internet access. We don't have to set up any physical appliances."

More Zscaler Zero Trust Exchange Platform pros

Cons

"The reporting feature needs improvement."

"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."

"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."

"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."

"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."

"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."

"SSL decryption: We had issues with learners using apps instead of using web browsers."

More iboss cons

"We have had instances where Duo Security stops working on a user's device, which we have fixed by uninstalling and then reinstalling it."

"They could just continue to add more integrations."

"Compared to other vendors, Cisco Duo is on the pricey end."

"Cisco Duo is definitely not doing things that others are not doing, so there is no unique selling proposition."

"I would like to see some features simplified, such as securing, configuring, and implementing Microsoft Remote Desktop."

"I would like to see Duo Security increase the time that the users have to log into the devices. The maximum time interval is 50 minutes at the moment, and I would like it to be 60 minutes. When you try to log into a device and have to authenticate yourself, sometimes it's not very pleasant. It's not the best thing particularly if you have to do this every 50 minutes, which is the maximum time that Duo gives. This makes it difficult to use and does not save time."

"There is a little bit of apprehension for some users thinking, well, "How do I know this app is not collecting personal information from my personal device?""

"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."

More Cisco Duo cons

"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 solution needs to improve a lot of aspects."

"The pricing is expensive and on the higher end. Honestly, in my opinion, it is not worth the price."

"The product is not reliable."

"The tool must provide IP-blocking features."

"The interface needs a bit of work."

"Zscaler CASB should include integrations with other SaaS applications."

"SCMP support would be one of the biggest improvements in my opinion. More speed improvements are also required."

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."

"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 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 expensive compared to one of its competitors."

"I rate the product pricing a seven out of ten."

"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."

"The pricing was a lot more than what we were paying for our previous solution."

"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."

"During testing we are allowed a certain number of licenses for free."

"The product’s pricing 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."

More Cisco Duo pricing and cost advice

"The product is a bit expensive."

"It is an auto-renewal subscription service."

"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."

"The solution has increased prices this year."

"The pricing is quite high, especially when it comes to the gateway."

"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."

"There is definitely an ROI."
