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

"iboss is among the few products providing inline filtering where no application is needed on the device."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"It was a very easy product to install. It can be deployed very fast."
"Content filtering is the most useful feature of iboss."
"From a use-case scenario, what I like the most is the plug-in. I like the fact that we can do the filtering of these devices offsite independent of the network they are connected to, and we do not have to have traffic coming back inside our network."
"iboss has significantly lowered the number of security incidents. It is crazy how much it blocks and how much it is aware of the outside danger."
"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"The console is cloud-based, which is something I really appreciate."
"They are users who, as mentioned before, utilize RDPAP and MDPAP. It includes functionalities related to finance, specifically in single sign-on."
"The authentication process is very smooth and secure."
"The most valuable feature is the ability for users to connect securely to the office using the VPN."
"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."
"The feature of Cisco Duo that I value the most is that it's easy to use; it monitors all our devices to ensure everything is updated before we're given access to those applications."
"I appreciate the secured push feature of Cisco Duo, which requires you to choose a number, because it enhances the security of your users, especially when combined with geolocation for a Verified Push, benefiting my company and our customers by making logins much more secure."
"The most appealing feature of Cisco Duo is the phone notification system that simply pops up on your phone."
"Cisco Duo has helped my organization reduce its overall authentication-related costs."
"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."
"The scalability of the solution is great."
"I find all Zscaler Private Access features valuable because each replaces flawed technologies, such as EPAs being replacements for VPN and PR as a replacement for PAM, so I can't mention only one valuable feature. Overall, Zscaler Private Access is a good solution."
"From a cost perspective, I would say fair market value, and then from an efficiency perspective, I notice a very good user experience, which is easy to use with Zscaler Zero Trust Exchange Platform."
"The policies are very easy to implement."
"The user interface of Zscaler Private Access is excellent. With proper knowledge and expertise, one can efficiently handle intricate enterprise environments without feeling overwhelmed. This leads to exceptional productivity for managed service providers. The user experience is remarkably streamlined, enabling the management of even the most complex enterprise setups without any excessive complications."
"It has been helpful in maintaining our infrastructure. The granular level control it offers allows us to set application policies per application for each user."
"Overall, the solution does a pretty good job at web filtering."
 

Cons

"Their on-premise hardware's network interface is capped at one gigabit, which is sort of a problem. If you stand a filter up where all traffic flows through that, according to them, in order to go above a gigabit, you have to have multiple devices, which in today's IT seems a little bit silly. They could easily put in an SFP port into their device that could accommodate 10 gigs or at least offer a box."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"File integrity monitoring would be very advantageous as an additional feature."
"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"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."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"SSL decryption: We had issues with learners using apps instead of using web browsers. This type of encryption is tough for any appliance in a BYOD environment."
"Sometimes when you call in support, you get someone who is just following a sheet. It feels like a runaround. You feel that you are running into that support wall."
"When you come to the push in Duo Security, there are some integrations where you have to use the code instead of the push functionality."
"The price of Cisco Duo could be better."
"To improve Cisco Duo, the biggest consideration is the licensing standpoint; the most common issue I've found is customers not setting up the Active Directory sync properly, leading to inflated licensing usage when they try to delete inactive users that are still being charged."
"Compared to other vendors, Cisco Duo is on the pricey end."
"We have users who move throughout the world, and their levels of connectivity change. It can be a challenge, if someone is in Bahrain, to authenticate via Duo."
"I wish that the support would be a little bit more prompt and a little bit more flexible because there are certain things that they will do and certain things they won't do."
"Duo Security should better organize its tile feature to organize applications better."
"We had some trouble with the password reset function."
"There are latency issues with the solution. They are small, however, they are there when you compare it to other vendors."
"Price-wise, it is a costly product and it should be reduced."
"While Zscaler supports client-initiated connections, it does not support server-initiated connections. This is a feature that Zscaler may consider adding in the future."
"They should work on a replica account. There could be alerts and replica files sent to the DLP team during data collection."
"Another area of improvement is implementation through non-client connectors. The solution can be implemented in two ways. One uses the back file; the other one uses client connectors. So the client connector is pretty fast, but when it comes to non-client connectors and procedures, it's kind of delayed and slow."
"Zscaler CASB should include integrations with other SaaS applications."
"It's an expensive solution."
"We faced certain migration and implementation challenges in executing the tasks, so I would suggest improvement related to the stability of the solution."
 

Pricing and Cost Advice

"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 have not priced the solution recently, but they were competitive with other vendors in the past."
"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 not expensive, and it is also not cheap. iboss is priced right in the sweet spot for the number of features it offers."
"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."
"It is affordable for what's coming to the table with it, but in this day and age, the cost is looked at under a microscope, and companies need to very finely define what is needed versus what is critical. In some cases, it might not be cost-effective for a company to have it. In a lot of other cases, it is the cost of doing business."
"The pricing was a lot more than what we were paying for our previous solution."
"The product’s pricing is reasonable."
"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."
"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."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"The technical support is good."
"In the long run, cloud services are not inherently costly."
"Zscaler Private Access can be an expensive solution, depending on the license type you will purchase."
"The pricing is quite high, especially when it comes to the gateway."
"The pricing is expensive and on the higher end. Honestly, in my opinion, it is not worth the price."
"Zscaler Private Access is extremely expensive."
"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 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."
