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.

Ease of Deployment and Customer Service: Cisco Duo's deployment is simple in cloud and hybrid environments, and its customer service is noted for promptness and informativeness. Zscaler, while also easy to deploy across diverse cloud setups, faces challenges with slower technical support response times.

Pricing and ROI: Cisco Duo is reasonably priced considering its comprehensive functionality, though it's not the cheapest option. It offers significant ROI through enhanced security. Zscaler Zero Trust Exchange Platform, seen as costly, provides pricing benefits for larger user bases, with value anchored in strong security returns and reliable user protection.

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

"Content filtering is the most useful feature of iboss."

"The security aspect of the solution, particularly the malware behind it, is excellent."

"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."

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

"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."

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."

"From a corporate perspective, I understand that it's important to keep the company data safe."

More iboss pros

"Documentation is the most valuable feature, and if you ever have to reach out to them with a question, their support is also fantastic."

"The most valuable aspect is the authentication and the SSO."

"By deploying Duo, we have virtually eliminated the risk of direct deposit redirection as a result of credentials that have been compromised via phishing."

"The deployment and installation process for Cisco Duo is quite straightforward, which is an advantage."

"The feature of Cisco Duo that I appreciate most is the push notifications."

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

"The two-factor authentication is valuable because that is the use case for which we are using it."

"I believe Cisco Duo is worth the investment, offering a good return on investment, as it is expensive but works very well without any downtime or high maintenance, and the support is also good."

More Cisco Duo pros

"This is a product that I recommend for anybody who wants a scalable, cloud-based solution."

"The scalability is pretty good."

"The tool's scalability is good."

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

"The most valuable feature of Zscaler Private Access is we do not have to connect to a VPN, it is seamless."

"Users get direct secure access to applications over the internet."

"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 UI is easy to use."

More Zscaler Zero Trust Exchange Platform pros

Cons

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

"The dashboards for local use could be better."

"The area I would like to see improvement in is the ability with in the reporter to navigate directly to the content the user is traversing. It is kind of there, but it's not perfect. Quite frequently, I receive links that lead me to pages with error messages."

"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."

"Its pricing could be better."

"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."

"To scale up, a new iboss Node Blade Chassis must be purchased."

"Sometimes, obviously, there are bugs."

More iboss cons

"The price of Cisco Duo could be better."

"Its management interface should also be improved. They should also improve its update period."

"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."

"For the back-end, there could be a few more security features applied."

"We found it difficult to integrate it into our broader product family of Microsoft tools and other applications used across our organization."

"Regarding the Premier licensing, it is a little bit pricey, but it is in the market range with the competitors."

"Integration between Duo Security and FTDs needs improvement. Integrating Next Generation Firewall safety with Duo Security currently requires a proxy agent between Active Directory and the appliance. It's an additional factor that we need to think about. It would be great to have direct integration with FTD so that we don't have to worry about middleware products. For the rest of the Cisco Secure solutions, the APIs need improvement."

"Regarding the stability and reliability of the Cisco Duo solution, we have experienced some outages over the last few years that are significant because people can't log in."

More Cisco Duo cons

"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."

"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."

"We'd like to have two-factor authentication that is quite simple."

"We would like to extend the SASE applications for Zscaler."

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

"We often face performance and latency issues with Zscaler SASE."

"There are some performance issues with the solution once the module addition begins"

"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."

Pricing and Cost Advice

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

"We have not priced the solution recently, but they were competitive with other vendors in the past."

"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."

"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."

"Cisco has the most expensive products because market leaders tend to charge a lot."

"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."

"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."

"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."

"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."

"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."

"It falls in line with everything else."

More Cisco Duo pricing and cost advice

"The solution is expensive."

"The technical support is good."

"Zscaler Private Access is extremely expensive."

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

"The cost is expensive. It depends on the number of users."

"Zscaler CASB is an expensive solution."

"It's an affordable solution"

"There is definitely an ROI."
