Senior Consultant Proxy Engineering at a financial services firm with 10,001+ employees
Deploying iboss leads to good return on investment, estimated around 70% to 80%.
Manager at Cyvogenix
We were able to implement zero trust extremely quickly because of the platform and its ongoing developments, including Cisco Duo Network Gateway, which enabled that transition to zero trust extremely quickly.
Global Associate Director, Services at a leisure / travel company with 1,001-5,000 employees
Not having MFA means you cannot put a price tag on that because you will be hit with ransomware immediately.
Director at a tech vendor with 10,001+ employees
The biggest return on investment was the ease of use for the end users to have that secondary authentication when logging into the critical systems.

When I see that I am trying to cut costs, for example, even when replacing Prisma, we have managed to save about over half a million dollars a year.
Cybersecurity Senior Program Manager at Dayforce
In terms of time savings, since users no longer manually connect to the VPN, access became seamless, improving user productivity, especially for remote users.
Technical Team Lead - Content Security at Valuepoint Systems
We don't have to purchase many components such as load balancers and proxy servers that were necessary in traditional setups.
Lead Engineer at FIS Global

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

Cloud gateway has strengthened remote web security and now needs better Mac and ISP support
The problem our organization had is that iboss failed for the Mac devices. It is not able to give a successful agent for the Mac agents. That is where in 2025, we had to migrate to the Palo Alto-based platform. If your use case is for just Windows laptops,you can consider this platform as an option One issue is the data center resiliency part. In India especially, they are not tied up with the Tier 1 ISPs like Tata or Airtel; they were having Tier 2 ISPs and encountered many issues reaching few major sites that my organization depends on, and they were having problems that they could not fix quickly. They also lack a mechanism to route that traffic within their data center; rather, they ask customers to make a pac file change to route it to Singapore explicitly. It would be better if they route from their backend , i mean even if I send it to India DC, they should be able to route it internally to make that work; however, they fail to do that and ask the customer to route it in the pac file. Another suggestion is that in China, they do not have the proper setup; they used to have numerous problems with slowness and lack of premium circuits in China as well. That leads to multiple sites working slowly with latency-related issues. So the main issue is the ISP-related problems that need to be solved.

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.
