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.

Cons

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

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

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

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

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

"It needs to offer SSO, single sign-on, and items of that nature."

Pricing and Cost Advice

"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."

"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."

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

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

"I only need the solution for IT staff, which makes it relatively cheap. If I deployed it for the whole company, it would be costly, so it depends on the number of users. Duo Security is affordable compared to other products in the segment."

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

"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 pricing, setup costs, and licensing has been good, with no issues. I am pleased that the prices remained stable after Cisco acquired the solution."

"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."

"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."

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

More Cisco Duo pricing and cost advice

"Zscaler Cloud DLP is moderately priced. We pay around 2 million rupees per year."

"The technical support is good."

"Zscaler CASB is an expensive solution."

"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 price is competitive."

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

"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."
