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.

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

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

"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."

"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."

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

"Technical support is pretty sharp and very responsive."

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

"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 is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."

More iboss pros

"The experience of deploying Cisco Duo is great; it is fast and not too complex in my opinion, as you can integrate basically anything into Duo, so I would say the experience is overall very great as an administrator."

"Cisco Duo helps minimize the risk of attack vectors and prevents unauthorized access to our data since it's tied with multi-factor authentication, which helps block threats."

"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."

"Cisco Duo benefits my organization by making it easy for me to reach out to customers using Cisco Duo so they can integrate on my platform using their credentials."

"The most valuable feature of Duo Security is the ability for the user to easily approve access. The application prompts the user, and they can see the location and the IP address. This makes it easy for the user to approve it and go through the process of logging in to the VPN."

"My impression of Cisco's identity intelligence capability to detect and respond to identity-based risks effectively is that it's a great product."

"Cisco Duo is very easy to deploy and the documentation is very thorough, which makes deployment straightforward."

"It was a simple way of providing two-factor authentication for remote access when we hit the COVID pandemic. It was very easy and quick to get it going."

More Cisco Duo pros

"The most valuable features are the File Type Control and SSL bypass policies. We"

"I like the web filtering capabilities."

"What I find most valuable in Zscaler Private Access is that it's a VPN. Its connectivity as a VPN is its most valuable feature."

"The most valuable features of Zscaler Private Access are reliability, scalability, and availability."

"The best feature is the ability to establish the connection between your public network and automatically connect to the intranet connection."

"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."

"We don't need to connect anymore. It is automatically connected when you log on in Windows."

"The scalability is pretty good."

More Zscaler Zero Trust Exchange Platform pros

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."

"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."

"Its pricing could be better."

"File integrity monitoring would be very advantageous as an additional feature."

"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."

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

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

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

More iboss cons

"Cisco Duo can be improved because people have their own personal mobile devices."

"Conversational AI in Cisco Duo is limited in its current application."

"I would appreciate seeing Cisco Duo improved with a tighter integration with Active Directory to secure not just Remote Desktop to a server, but all the remote levels of connection that you can make to a server."

"Cisco Duo could be improved, possibly by adding features for the healthcare space. If you're selling something to a healthcare provider, there needs to be consideration for how to launch Cisco Duo with a handheld device that is not native, where you can install the application."

"Most of my colleagues from other companies use the Microsoft MFA solution because it's included in Office 365. Few people are considering Cisco Duo. That's the primary problem in our area. It's a solution mostly adopted by Cisco users."

"There is always room for improvement."

"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."

"Improving Cisco Duo might involve alerting us about telephony credits when people receive texts. We hit zero at one point, and we were running around in circles without any idea until I discovered it. That's my only complaint."

More Cisco Duo cons

"There aren't really any missing features that I have witnessed."

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

"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."

"It has a limitation, if you are creating a rule or something for a web application or something, you could only add five users, not more than that. Five or four users are only included in a rule. If you want to create a rule for more than five or four users, you have to go through other methods, not particularly with the application. Working within the application with this method would be quite easy as compared to listing a URL or a normal IP address."

"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."

"The solution needs to improve a lot of aspects."

"I can't speak to any missing features."

"We have issues with the tool's maintenance and networking. It should be able to work in offline mode as well."

Pricing and Cost Advice

"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."

"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."

"The overall pricing for iboss is very competitive and transparent."

"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 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."

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

"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."

"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 am not aware of the pricing. There are two departments, and I don't have any information about them."

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

"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."

"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."

"The product has reasonable pricing."

"There is definitely an ROI."

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

"The solution has increased prices this year."

"Zscaler Private Access is extremely expensive."

"The solution is expensive."

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

"It's an affordable solution"
