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.

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.

Zero trust access has transformed remote connectivity and now simplifies secure app usage

Zscaler Zero Trust Exchange Platform, especially Zscaler Private Access, is very strong, though there are a few areas where improvements can be made. One challenge observed is around initial troubleshooting and visibility. While Zscaler Private Access provides logs, it can sometimes take time to pinpoint the exact cause of access issues, especially in complex environments with multiple policies and identity integration. Another area is the dependency on identity and connector health. Since Zscaler Private Access is heavily reliant on app connectors and identity providers, any issues with these components can impact user access, making proper monitoring critical. During the initial setup, policy configuration and application onboarding require careful planning, especially for larger environments with many applications. These challenges are manageable with proper design and monitoring. Overall, the platform delivers strong security and user experience. I would recommend a few improvements, especially around user interface, reporting, and troubleshooting experience. From a user interface perspective, while the platform is powerful, the policy configuration and navigation can feel complex, especially for new users. A more simplified and intuitive layout for policy mapping and application access would help reduce the learning curve. In terms of reporting, Zscaler Private Access provides logs, but having more built-in customizable dashboards and analytics would be very helpful. Better visibility into user access patterns, application performance, and real-time troubleshooting insights would improve operational efficiency. From a support and troubleshooting standpoint, it would be beneficial to have more granular centralized visibility, allowing for quick end-to-end tracing of a user request from authentication to application access without switching between multiple views. These improvements would make the platform even more efficient, especially for large-scale enterprise environments.

Quotes from Members

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

Pros

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

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

"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."

"This product is solid, fairly easy to use, and reliable."

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

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

"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."

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

More iboss pros

"The solution is pretty secure."

"Cisco Secure solutions are great for detecting and remediating threats across our infrastructure from end to end. The integration of Talos in SecureX is great. Everything is clear in one dashboard. You have a dashboard there, your dashboard, and now you can have one look in your dashboard and see everything. It's on one pane of glass."

"Cisco Duo seems very scalable; in my experience, I started with a small-medium business, and in my last contracting position, it was a large one for a major worldwide airline that had hundreds of thousands of devices that could use Cisco Duo, and it scaled very well."

"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."

"It has definitely made our company more secure."

"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."

"Duo Security improved my organization by helping us secure all access points within the company infrastructure."

"The feature of Cisco Duo that I prefer the most is the policies, being able to control what we need to within the policies. You can get pretty granular."

More Cisco Duo pros

"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."

"Overall, Zscaler Zero Trust Exchange Platform, especially Zscaler Private Access, has been a strong and reliable solution for enabling secure access without any need for traditional VPNs."

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

"The most valuable feature is its seamless integration capabilities, streamlining the process by eliminating the need for extensive installations."

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

"Subsequently, after this, there is a huge reduction, as the vulnerabilities, especially the security bugs that were coming prior to Zscaler Zero Trust Exchange Platform, were about 20,000 to 22,000 and have come down more than 40 percent, which is definitely an advantage over the previous product."

"The VPN is great for the stability on offer and for the cloud updates and insights you can get."

"Sandboxing, DLP, and SSL inspection engine are the most valuable features of Zscaler SASE."

More Zscaler Zero Trust Exchange Platform pros

Cons

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

"Sometimes, obviously, there are bugs."

"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."

"The area I would like to see improvement in is the ability within the reporter to navigate directly to the content the user is traversing."

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

"One thing I would like to see differently with their Zero Trust platform is that some of the AI aspects related to high-risk activities have more false positives."

"The dashboards for local use could be better."

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

More iboss cons

"I believe Cisco Duo needs to be improved on the delay process because there is a delay when we send a Duo Push or when we are signing into any applications."

"We already have Active Directory enabled in our routers and switches. However, if we could do two-factor authentication, then it could go a long way since no one's getting into them unless you want them to."

"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."

"There is a little bit of apprehension for some users thinking, well, "How do I know this app is not collecting personal information from my personal device?""

"The pain point for us at one point was the Duo Authentication Proxy since we're on-premises and not in the cloud. We had to have a proxy machine that's in our DMZ to talk to Duo for us. The configuration of that was a little complicated."

"I wouldn't mind seeing some options for remembering a device for a short period of time or a specific login, particularly for administrative engineering staff, as we may be logging in to four or five different services."

"Removing the need for a password would be a positive change as well as the ability to cover all the different enterprise applications. They don't have coverage for everything."

"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."

More Cisco Duo cons

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

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

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

"This is a great solution, I'm just searching for an alternative because the costing or the commercials for this type of solution tends to be a little high, although we have been using it for a year already."

"The DX layer could be better if it had improved visibility."

"The solution's granularity should be improved because it has limited granular options to control, visible, allow, block, delay, and receive."

"There are latency issues with the solution. They are small, however, they are there when you compare it to other vendors."

"The only issue with Zscaler Cloud DLP is that it only gives you DLP protection from web traffic, which is flowing out, while a full-blown DLP solution such as Forcepoint or Symantec gives you DLP coverage for multiple channels. Zscaler Cloud DLP doesn't give you coverage for email, fax, and USB channels, and this is the only challenge or room for improvement in the solution. It's just an extension on top of what you're buying on the proxy, so it's just an added layer, and it doesn't cover DLP on a very broad level. I'm unsure if Zcaler is in the business of competing with a full-blown DLP solution, and if there's a plan to expand the features of Zscaler Cloud DLP beyond the web channel because you'll have to deploy a full-blown agent for it. I'm unsure if this is on the cards because the solution is just an added layer that you get with your proxy. I've asked the Zcaler team whether there's a plan to go full DLP in the future, but I didn't get a positive response. There isn't any feature I'd like added to Zscaler Cloud DLP currently, because anything you could think of that should be in cloud or SaaS solutions is already there, except for machine learning, as it's the only functionality that seems to be lacking in the solution. Machine learning is an additional policy available in other DLP solutions in the market, but my team didn't find it in Zscaler Cloud DLP."

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 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."

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

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

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

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

"Duo Security is free."

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

"It falls in line with everything else."

"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."

"It was very reasonable."

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."

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

"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."

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

"The technical support is good."

"It's an affordable solution"

"Zscaler Private Access is extremely expensive."

"Zscaler Private Access can be an expensive solution, depending on the license type you will purchase."
