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

"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."

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

"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."

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

"Its initial setup was straightforward."

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

"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."

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

More iboss pros

"We were considering purchasing other products, like AMP for Endpoints, and it was not properly integrated with the firewall function. It might be better now with SecureX."

"The biggest return on investment for me when using Cisco Duo is gaining time, as I don't have to look at ten different MFA apps, and I know it will work."

"The decision to choose Cisco Duo is based on the many features it offers that we did not find in other applications, and since we were already using Cisco for our other needs, it made sense not to switch to a competitor."

"Cisco Duo has provided substantial value, primarily in saved time, but also in low cost because administrators do not have a significant workload with Cisco Duo."

"The winning point for Cisco Duo over others is its simplicity; it is just a security solution in a box, and it integrates very easily."

"You can do online and offline authentication."

"It's a lot easier for our end users to connect to our network. You don't have to type in a code. You get push notifications, that's probably the best thing about it. The fewer clicks they have to do to be online, the better it is. They can easily get into the network and do remote work."

"Duo Security just adds another layer; it's a great addition to the security of any network infrastructure."

More Cisco Duo pros

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

"The policies are very easy to implement."

"The user interface of Zscaler Private Access is excellent. With proper knowledge and expertise, one can efficiently handle intricate enterprise environments without feeling overwhelmed. This leads to exceptional productivity for managed service providers. The user experience is remarkably streamlined, enabling the management of even the most complex enterprise setups without any excessive complications."

"As a cloud-based service, it is very easily implemented."

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

"Zscaler's technical support is quite good."

"It is straightforward to set up."

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

More Zscaler Zero Trust Exchange Platform pros

Cons

"The reporting feature needs improvement."

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

"Sometimes, obviously, there are bugs."

"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."

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

"Its pricing could be better."

"The dashboards for local use could be better."

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

More iboss cons

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

"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."

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

"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."

"The only time I really had some negative feedback for them was about the UI of their mobile app, but they improved it in the last version. It is good on the functionality side, but their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. If you are on a monthly term or a yearly contract, you basically pay the same price, and that is very unusual. Normally, there is a discount when someone signs up for the 12-month system."

"There might be a little slowness, but that could be my connection."

"We had a lot of trouble configuring the password reset function, and as a result we now have a second channel that bypasses Duo to allow users to reset their password."

"They could just continue to add more integrations."

More Cisco Duo cons

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

"Sometimes, support takes time since the solution has some bugs that need fixing."

"More on-prem infrastructure is required when Zscaler Private Access is to be implemented as a single point of entry."

"There could be a feature to view the VPN tunnel activities in terms of configuration."

"What could be improved in Zscaler Private Access is its notification. For example, if there's a speed issue, there should be a pop-up that alerts the user about it. If there is a network quality issue, for example, it isn't good enough to connect to, or the network quality is bad, there should be a notification from the solution. Zscaler Private Access also needs improvement in terms of its interface and security."

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

"It's an expensive solution."

"From a user interface perspective, while the platform is powerful, the policy configuration and navigation can feel complex, especially for new users."

Pricing and Cost Advice

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

"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 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."

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

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

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

"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 has a fair pricing model. I know they have different tiers, but it would be nice to have different types of licenses for certain groups of users in our organization. That way, we wouldn't have to lump everybody into one group. That would be also one complaint."

"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."

"Their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. There are no additional costs to the standard licensing costs."

"It falls in line with everything else."

"Our licensing fee is currently on an annual basis."

More Cisco Duo pricing and cost advice

"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."

"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."

"The product is a bit expensive."

"The product is a little more expensive than other tools."

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

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

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

"My company is a Zscaler Private Access partner, so the customers pay for the license fees."
