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. Zscaler needs to work on connection stability and support for legacy systems. Introducing a single-tenant option and pricing adjustments would better position it in the market.

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.

Secure access has improved remote work and has reduced vulnerabilities across our workforce

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. However, according to discussions with Zscaler Zero Trust Exchange Platform, they said that by the end of mid-2026, they are exploring these features, and probably those features can be incorporated or embedded into this particular system. That is the only major negative point.In terms of responses, Zscaler Zero Trust Exchange Platform is good. In terms of controlling vulnerability, it is good. The only cons I have noticed is that it is a bit slower, and sometimes it is unable to identify the source. These are the key areas for improvement.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."

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

"Our primary use case for this product is DLP,"

"Its initial setup was straightforward."

"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."

"The console is cloud-based, which is something I really appreciate."

"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."

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."

"Cisco Duo scales very well with the growing needs of my company; during COVID, when we had a higher number of users, there were no problems at all."

"All features of the solution are effective, particularly those involved in identifying vulnerabilities and updates."

"It is a great system regarding multi-factor authentication, specifically after we did the integration with Active Directory, allowing us to manage the users who use the VPN, our main gateway for VPN Cisco ASA Secure, with full administration."

"The product is reliable and easy to use."

"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."

"It's easy to deploy. It's easy to manage. It's easy to integrate with other applications."

"The Verified Duo Push feature is valuable. It gives an extra level of security beyond just the regular push."

More Cisco Duo pros

"With SASE, we have a single platform that covers multiple task services with which we need to control access. All the features are equally valuable."

"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."

"The most valuable features of Zscaler CASB are API integration and DLP."

"I like its ease of use. It has a single pane of glass for the ZIA and ZPA pieces. It is very manageable. It is also very easy to deploy for secure access, and it gives half-decent coverage for visibility in terms of what the users use and what data is being proxied through the access gateway."

"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 Live Logs are a cool feature. We can directly identify issues and divert user traffic."

"SASE's most valuable features are proxy and content filtering."

"The tool's scalability is good."

More Zscaler Zero Trust Exchange Platform pros

Cons

"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."

"Iboss is growing so fast that it is often hard for them to keep up with the challenges."

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

"I'd like to see them accelerate development on the security side, particularly around data loss prevention."

"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."

"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."

"Sometimes when you call in support, you get someone who is just following a sheet. It feels like a runaround. You feel that you are running into that support wall."

"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."

More iboss cons

"We use Yubikey for pushing it to the phones. Yubikeys can get expensive because people tend to lose those for some reason. Fifty dollars a device is pretty high."

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

"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."

"Regarding the pricing, setup costs, and licensing, I find that for some companies using Azure, they question why they should switch when they already have Microsoft Authenticator, which can make it commercially challenging when explaining why they need to transition to Cisco Duo."

"General announcements when new features come out with Cisco Duo should be broadcasted to customers who are using it, which might bring more accessibility to their documents so users can be more in tune with updates."

"The price of Cisco Duo could be better."

"Its documentation must be in French because we are a French-speaking country. They should also provide more training documentation. Its management interface should also be improved. They should also improve its update period. If I compare its update period with other products such as Palo Alto firewalls, this solution is really slow in updates."

"I think we'd need more experience to learn Cisco Duo because we're just at the beginning of using it."

More Cisco Duo cons

"Zscaler Cloud DLP needs to improve its compatibility with other security tools."

"Sometimes applications crash on some machines, and we’d like Zscaler to give us some information as to why that may have happened. We’d like more detailed reports."

"There is some issue while accessing the portal. It takes too long."

"Conflicts arise if you do not have the same management teams on the product."

"To enhance their offering, it is advisable for them to focus on strengthening the foundation of their architecture. Additionally, they should consider integrating a broader range of services that go beyond what managed service providers typically offer independently."

"There is improvement in enhancing proper manageability, policies, and logs. So, log management could be improved."

"We faced certain migration and implementation challenges in executing the tasks, so I would suggest improvement related to the stability of the solution."

"Occasionally, there are certain delays in report generation."

Pricing and Cost Advice

"It is probably in line with other solutions, but I do not deal with the financial side."

"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 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."

"It is expensive compared to one of its competitors."

"The product’s pricing is reasonable."

"The cost was reasonable. Licensing was pretty straightforward for a change."

"I haven't seen any information on the pricing in four years, so I can't comment on that."

"Its price is reasonable. It is not highly expensive."

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

"It was very reasonable."

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

"I haven't seen it in a while, but it's at par with everything else licensing-wise."

More Cisco Duo pricing and cost advice

"Zscaler DLP solution is expensive, with a fixed pricing structure that is billed annually and monthly. There are no additional costs for licenses."

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

"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."

"As per industry leads, Zscaler CASB is an expensive solution."

"There is definitely an ROI."

"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."

"Pricing for Zscaler Private Access is moderate. It's acceptable, though I can't give you the exact price currently. It's not too expensive, and on a scale of one to five, I would rate it a four out of five in terms of pricing."

"Zscaler SASE software is quite expensive compared to other solutions"
