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

"Content filtering is the most useful feature of iboss."
"From a corporate perspective, I understand that it's important to keep the company data safe."
"iboss is among the few products providing inline filtering where no application is needed on the device. It operates on the network side and is not device-based. This feature was one of the main reasons why we stayed with them for so long."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"The console is cloud-based, which is something I really appreciate."
"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."
"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"Its initial setup was straightforward."
"In the world of network security, it is outstanding and very strong."
"I can say that it is difficult to measure the direct return on investment, but what I can say is that we are safer and feel more comfortable having this security implemented than before."
"The biggest benefit of Cisco Duo for my customers is the license because they count licenses for the user—one user can use many applications integrated with Cisco Duo."
"I believe Cisco Duo is worth the investment, offering a good return on investment, as it is expensive but works very well without any downtime or high maintenance, and the support is also good."
"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."
"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 app has greater stability than rival solutions such as Google Authenticator, and Duo Push authentication is a valuable feature."
"Duo offers dual-factor authentication for our logins. I put in my credentials and hit go. Then I get an alert on my Apple watch, and I approve it. That part is just phenomenal."
"The scalability by definition is kind of intrinsically built-in."
"Zscaler's technical support is quite good."
"The product's most valuable features are cloud-based services and secure internet access. We don't have to set up any physical appliances."
"It is a stable solution."
"The most valuable features of Zscaler Private Access are reliability, scalability, and availability."
"The scalability is pretty good."
"I would recommend Zscaler Cloud DLP to others because it's the best proxy product in the market at the moment."
"With SASE, we have a single platform that covers multiple task services with which we need to control access. All the features are equally valuable."
 

Cons

"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"The reporting feature needs improvement."
"It is stable, but due to growth, it can sometimes be less stable than wanted."
"The endpoint-type solution is an area that needs some improvement."
"I am currently doing a PoC of the zero trust aspect of it. Compared to other similar solutions, it is hard to get around each feature. It takes a while to get used to it."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"Sometimes, obviously, there are bugs."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"Cisco Duo can be improved with better ways to set users up. Currently, we might not be doing it perfectly as we're having them email in phone numbers to get them set up with Duo Mobile."
"My experience with Cisco Duo's strong security authentication system is that sometimes there are difficulties, and sometimes users just won't be able to log in. We have to reset their password so they can use Duo."
"Improving Cisco Duo might involve alerting us about telephony credits when people receive texts. We hit zero at one point, and we were running around in circles without any idea until I discovered it."
"Cisco Duo could be improved by building the agent with the many agents we already use, such as Cisco AMP and Cisco Secure Client, which would simplify our environment by eliminating the need for a third agent for secure applications."
"Duo was clearly purchased, and Cisco has a lot of other panels for their Firepower products, et cetera. They need to continue bringing it, Umbrella, and the endpoint pieces even more together and make the integration a little more seamless among all of them."
"General announcements when new features come out with Cisco Duo should be broadcasted to customers who are using it, which might bring more accessibility to their documents so users can be more in tune with updates."
"At the moment, I believe that more integration between Cisco Duo Identity Intelligence and the classic Cisco Duo console can be improved, since it is still a separate platform, and when I click on Identity Intelligence, I have to open a new window and log in again."
"Cisco can further enhance the integrations, as they possess exceptional integrations with various providers' products and feature sets."
"Price-wise, it is a costly product and it should be reduced."
"The tool must provide IP-blocking features."
"There could be a feature to view the VPN tunnel activities in terms of configuration."
"In the next release, I would like to see RE2 Regex supported."
"They should work on a replica account. There could be alerts and replica files sent to the DLP team during data collection."
"I rate it a seven because I am still working through some kinks from a performance and a support perspective."
"Zscaler CASB should include integrations with other SaaS applications."
"Sometimes applications crash on some machines, and we’d like Zscaler to give us some information as to why that may have happened. We’d like more detailed reports."
 

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."
"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."
"It is expensive compared to one of its competitors."
"Its price is reasonable. It is not highly expensive."
"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."
"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."
"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."
"You pay per user when using this solution and the pricing is fair."
"During testing we are allowed a certain number of licenses for free."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"It's very simple. Its price is fair. We use the hardware tokens as well. You get what you pay for. In terms of licensing, Cisco has very complicated products, but Duo Security was surprisingly easy."
"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 pricing is quite high, especially when it comes to the gateway."
"It's an affordable solution"
"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 product has reasonable pricing."
"Zscaler Private Access can be an expensive solution, depending on the license type you will purchase."
"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."
"Zscaler Private Access is extremely expensive."
