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.

Ensures comprehensive protection with seamless threat logging and efficient policy management
My favorite feature of Cisco Umbrella is probably just the DNS and the fact that when a security threat happens, all of that gets logged in their Umbrella portal, and it's very easy to find who's been accessing the site and how many people have accessed it, so that we can go to them and make sure they're not compromised. The features of Cisco Umbrella benefit my company by providing less time to search for things through logs, to look for what we need. It's just one place to go, and we just search for it, and we find it really fast. The fact that there's a virtual database that has all that information is great on our portal.

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."
"Our primary use case for this product is DLP,"
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"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 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."
"The most valuable feature is the ability to block users from reaching places that they should not even try to reach has been a boon."
"Cisco's Umbrella client product is superb, it worked so well for us and was easy to deploy."
"The feature I appreciate most about Cisco Umbrella is the dashboard and how easy it is to see the reporting, what is blocked and allowed, and it makes it very user-friendly."
"The most valuable features of this solution are the Web Filtering and the APT."
"As far as the IT infrastructure team goes, we're all happy with the product; it definitely takes a lot of load off of our plate and it's been functioning very efficiently and effectively, doing everything we need it to do."
"Improves security through DNS visibility, which can block malware, phishing, C&C, etc."
"With the Experience Insights feature of Cisco Secure Access, we've seen impacts on the management of user connectivity by allowing us to deliver safe connectivity."
"I was pretty amazed by the wide variety of security features and reports on a single dashboard."
"Zscaler's technical support is quite good."
"The most valuable feature is its seamless integration capabilities, streamlining the process by eliminating the need for extensive installations."
"The tool's scalability is good."
"What I find most valuable in Zscaler Private Access is that it's a VPN, and its connectivity as a VPN is its most valuable feature."
"The product’s most valuable features are data discovery, activity control, and zero trust exchange."
"Overall, Zscaler Zero Trust Exchange Platform, especially Zscaler Private Access, has been a strong and reliable solution for enabling secure access without any need for traditional VPNs."
"The best feature is the ability to establish the connection between your public network and automatically connect to the intranet connection."
"The most valuable features of this solution are the CASB solutions, which is protecting their Office 365."
 

Cons

"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"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."
"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."
"The dashboards for local use could be better."
"The solution's technical support is not very good."
"I think it's a very basic solution, and because of that, Cisco Umbrella would not be a suitable solution for large companies."
"It needs a better price point."
"If the security issues are taken care of it would be better."
"They need to improve analytics so they report on more of the specifics of user activity."
"The different levels of security, such as backend security and internet security, need improvement."
"This solution is difficult to configure."
"All in all, I can not recommend OpenDNS as a one-size-fits-all solution for security and compliance, especially for larger organisations."
"We faced certain migration and implementation challenges in executing the tasks, so I would suggest improvement related to the stability of the solution."
"Occasionally, issues arise in the LogStack by a third party, particularly for government websites accessed by numerous users."
"Sometimes, support takes time since the solution has some bugs that need fixing."
"SCMP support would be one of the biggest improvements in my opinion. More speed improvements are also required."
"The pricing is expensive and on the higher end. Honestly, in my opinion, it is not worth the price."
"On a scale from one to ten, I would rate Zscaler Private Access at only a three or four."
"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."
"The connectivity monitoring part should be included in the core license without any extra charges."
 

Pricing and Cost Advice

"It is expensive compared to one of its competitors."
"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."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"The overall pricing for iboss is very competitive and transparent."
"It was a little bit expensive on a per seat basis, but the company I was running was only a midsize Australian company, and it was a reasonable budget per computer for that system. It started off being a free product, and then Cisco bought it, and it went to a reasonable price. I was using Cisco AMP as well. So, my per computer cost was reasonably high, but for a small company, it was within an acceptable level."
"The price should be slightly lower than the current price because if you look at the whole solution, it is simply a threat intelligence solution to block blacklisted things. The price should be lower looking at the features provided by the solution. The price isn't too high either, but it could be lower."
"We did a good negotiation, and at the moment, its price is fine."
"Pricing and licensing of Cisco Umbrella is a bit confusing because you have to separate the DNS solution and the full-feature solution. Cisco in Portugal helped us understand which one was the right one for us."
"You can request an evaluation license​."
"Cisco uses subscription models for the pricing and there are three subscription plans."
"Our licensing fees are on a yearly basis."
"The price is quite good."
"Zscaler Private Access can be an expensive solution, depending on the license type you will purchase."
"The cost is expensive. It depends on the number of users."
"In terms of market positioning, I would describe Zscaler Private Access as offering optimal pricing. Based on our experience, Cato Networks tends to be slightly more expensive."
"Zscaler Private Access is extremely expensive."
"The product has reasonable pricing."
"The price is competitive."
"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."
"There is definitely an ROI."
