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

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

"Technical support is pretty sharp and very responsive."

"Valuable features: Within the filter: Controls (Web categories, applications, and Allow/Block list) and Network (local Subnets). Within the reporter: Logs (Event Log) and Reports."

"Granular setup, which was able to set different levels of filters using the OUs in the AD."

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

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

"Our primary use case for this product is DLP,"

"The solution has massively improved our security posture, giving us full visibility into what our staff does online."

More iboss pros

"If you have to log in to something, you must go to Duo Security to confirm that you're who you are on your phone."

"I lead an IT organization that has a significant amount of technical debt, and we're not in a zero-trust architecture yet. I'm pushing in that direction. Duo helps me considerably with my identity in an environment where I don't have zero trust. It's helping me bridge the gap until I can build a zero trust architecture."

"The Verified Duo Push feature is valuable. It gives an extra level of security beyond just the regular push."

"My overall rating for the solution is ten out of ten."

"The most valuable feature of Duo Security is the ability for the user to easily approve access. The application prompts the user, and they can see the location and the IP address. This makes it easy for the user to approve it and go through the process of logging in to the VPN."

"The ability for users to authenticate via phone, from any random phone number, has been very helpful for managing a distributed workforce. Using it across a distributed network for securing access to our applications is big for us."

"Cisco is the perfect product for our current size, and I don't think we'll have problems with scalability as we grow."

"It was a simple way of providing two-factor authentication for remote access when we hit the COVID pandemic. It was very easy and quick to get it going."

More Cisco Duo pros

"The best feature is the ability to establish the connection between your public network and automatically connect to the intranet connection."

"On DLP terms, Zscaler Cloud DLP ensures that data doesn't go outside of the organization. So on the network level, Zscaler does a pretty good job."

"The agent's versatility is notable, used for digital experience monitoring to collect valuable endpoint metrics for troubleshooting."

"The product's most valuable features are cloud-based services and secure internet access. We don't have to set up any physical appliances."

"Yes, it is very stable. I have never seen it go down, not once."

"This secure connection allows users to connect to the Zscaler VPN and access the resources on the office network, making it a highly valuable component of our system."

"The policies are very easy to implement."

"The UI is easy to use."

More Zscaler Zero Trust Exchange Platform pros

Cons

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

"Sometimes, obviously, there are bugs."

"Sometimes the agent stops working in iboss, and we have to reinstall the agent."

"Iboss is growing so fast that it is often hard for them to keep up with the challenges."

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

"Fold that in with the risk intelligence they're getting from all of the different subscriptions they are a part of. Now, these security companies subscribe to things like emerging threats, databases, etc. You can fold all this intelligence to decide what's happening on an endpoint. I would love to see them start moving into that space. That would compete directly with Microsoft. Maybe that's why they haven't. Having that ability native within the solution would be great. The other area in which I would love to see improvement is more detailed descriptions of why they block websites."

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

"The dashboards for local use could be better."

More iboss cons

"Technical support could be improved. I don't think all support should have to go through an agreement."

"Smart Licensing needs improvement. It's terrible. We have problems with it every year and we need to involve support to fix it."

"It took me a while to figure it out. I went to every user and forced them to set it up. I might have done it the long way."

"Duo Security could improve by being more compatible with other vendors."

"Sometimes, it's a little harder for customers to adopt."

"Certain customers can not use this product because it is cloud-based."

"I'm unsure how to disable the ping notification sound on my phone when using Cisco Duo."

"It already integrates with lots of products, but it can integrate with more products. There should be easy integration with Cisco products because sometimes, it can be quite complicated."

More Cisco Duo cons

"There aren't really any missing features that I have witnessed."

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

"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."

"Occasionally, there are certain delays in report generation."

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

"The product must allow users to check logs for an entire year in the local console."

"Zscaler Cloud DLP needs to improve its compatibility with other security tools."

"Setup is a bit complex because there are many steps that need to be taken before onboarding and activating the solution."

More Zscaler Zero Trust Exchange Platform cons

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."

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

"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."

"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."

"It's a bit confusing because we're on a three-year plan with a certain number of licenses, and we've gone over that number. They told us that when we renew, they will add all these licenses. We've expanded quickly, so everyone's kind of scared because no one knows what the bill is with the long pricing cycle."

"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."

"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."

"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."

"Duo Security's pricing is good, fair, and very comparable to today's market."

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

"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."

More Cisco Duo pricing and cost advice

"Zscaler Private Access is extremely expensive."

"The solution has increased prices this year."

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

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

"The price is competitive."

"Zscaler SASE software is quite expensive compared to other solutions"

"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."

"It is an auto-renewal subscription service."
