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

"Our primary use case for this product is DLP,"
"Technical support is pretty sharp and very responsive."
"Content filtering is the most useful feature of iboss."
"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"The iboss system is highly reliable. The false positive rates are small compared to some other systems we've experienced through other partner agencies who use competing solutions."
"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 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."
"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."
"The multi-factor authentication process and the geo-locking features are great."
"It is a great system regarding multi-factor authentication, specifically after we did the integration with Active Directory, allowing us to manage the users who use the VPN, our main gateway for VPN Cisco ASA Secure, with full administration."
"Duo Security provides a high level of certainty regarding the identity of the individual performing an action. Whether it's logging into a system, using VPN, or utilizing Autopay, establishing that trust is crucial. I can't imagine any security company, organization, or IT team that wouldn't prioritize having multifactor authentication enabled when accessing critical systems."
"The deployment and installation process for Cisco Duo is quite straightforward, which is an advantage."
"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."
"Duo Security gives us an additional layer of security that would give us added confidence that our network will be less likely to get hacked, compromised, or otherwise."
"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 push notifications and the integrations they offer are valuable. Their mobile app is very useful. It is very easy to use."
"Overall, the solution does a pretty good job at web filtering."
"The most valuable feature is its seamless integration capabilities, streamlining the process by eliminating the need for extensive installations."
"The scalability is pretty good."
"The most valuable feature of Zscaler Private Access is the categorization of the dynamic URLs which keeps the customer's environment protected. The threats and the malware are correctly categorized."
"I like the web filtering capabilities."
"The most valuable features are the File Type Control and SSL bypass policies. We"
"The VPN is great for the stability on offer and for the cloud updates and insights you can get."
"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

"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."
"The area I would like to see improvement in is the ability with in the reporter to navigate directly to the content the user is traversing. It is kind of there, but it's not perfect. Quite frequently, I receive links that lead me to pages with error messages."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"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."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"The reporting feature needs improvement."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"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."
"Cisco can further enhance the integrations, as they possess exceptional integrations with various providers' products and feature sets."
"I have not seen ROI with Cisco Duo; probably the opposite, because it impedes productivity time to be able to get into the system. You have to authenticate and do your regular login and your Active Directory logins."
"I believe there are two new features. I am interested in adding auto-admin services and incorporating icons for easier navigation. This could contribute to a new business idea platform. I have seen the features, and they make things easier, resolving issues from before. The platform has been updated, and there's now another link in my platform for media access. When it comes to improvements, the UI can be more user-friendly, and there is room for easier navigation. Perhaps there could be enhancements in customization. I haven't faced issues in storage or backup, but I am open to improvements in customization functionality. It's not my environment, but I see possibilities for improvement in the deployment of funds. The addition of new features is appreciated, and for customization, it could provide more freedom for users."
"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."
"The product could be more intuitive on the app."
"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."
"They could just continue to add more integrations."
"Cisco Duo did not help reduce the cost of the overall authentication method that we have in our company; instead, it increased, obviously."
"There is improvement in enhancing proper manageability, policies, and logs. So, log management could be improved."
"We have issues with the tool's maintenance and networking. It should be able to work in offline mode as well."
"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."
"I can't speak to any missing features."
"Zscaler CASB should include integrations with other SaaS applications."
"The pre-defined dictionaries could be improved."
"The stability could be improved."
"They should work on a replica account. There could be alerts and replica files sent to the DLP team during data collection."
 

Pricing and Cost Advice

"The overall pricing for iboss is very competitive and transparent."
"It is expensive compared to one of its competitors."
"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 probably in line with other solutions, but I do not deal with the financial side."
"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."
"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 haven't seen it in a while, but it's at par with everything else licensing-wise."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"During testing we are allowed a certain number of licenses for free."
"It has a fair pricing model. I know they have different tiers, but it would be nice to have different types of licenses for certain groups of users in our organization. That way, we wouldn't have to lump everybody into one group. That would be also one complaint."
"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."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"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 product is a little more expensive than other tools."
"The pricing is quite high, especially when it comes to the gateway."
"Zscaler Private Access can be an expensive solution, depending on the license type you will purchase."
"As per industry leads, Zscaler CASB is an expensive solution."
"Zscaler DLP solution is expensive, with a fixed pricing structure that is billed annually and monthly. There are no additional costs for licenses."
"It is an auto-renewal subscription service."
"It's an affordable solution"
"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."
