Executive SummaryUpdated on Nov 2, 2025

Cisco Umbrella and Zscaler Zero Trust Exchange Platform are major contenders in the network security solutions category. Cisco Umbrella appears to have the upper hand due to its ease of integration and strong DNS-based security capabilities, compared to Zscaler's focus on comprehensive access controls and application-level security.

Features: Cisco Umbrella delivers in-depth DNS-based security features, web content filtering, and malware protection with customizable categories, offering effective visibility and user safeguarding on unmanaged networks. Zscaler emphasizes secure access, user management, and application-level security, providing a robust suite with strong cloud integration and seamless protection, making it an asset for complex environments needing comprehensive access controls.

Room for Improvement: Cisco Umbrella users express a need for stronger malware protection engines, enhanced policy flexibility, and better reporting integrations. They also seek improved IPv6 support and more efficient purchasing processes. Zscaler faces criticism for latency issues, limited multi-tenancy and legacy system support, and calls for better user interface intuition and configuration granularity.

Ease of Deployment and Customer Service: Cisco Umbrella is praised for easy deployment in cloud and hybrid settings, requiring minimal on-premises infrastructure, and is backed by strong technical support, though some desire quicker response times. Zscaler offers robust deployment options and smooth cloud integration, but its deployment can be complex in certain areas, with varied support responsiveness.

Pricing and ROI: Cisco Umbrella is perceived as costly yet offers good ROI with flexible licensing and reduced hardware investment, seen as favorable given its features. Zscaler, noted as pricier, requires additional licenses for full coverage but provides significant ROI by integrating essential security features within a single platform, enhancing security posture and operational efficiencies.

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 internet navigation safety and boosts productivity

The features of Cisco Umbrella I prefer most are DNS protection and traffic redirect. With Cisco Talos's threat intelligence, we reduce the impact of malware traffic in our network, and we currently see the behavior of equipment and choose the correct sites. Cisco Talos has helped us reduce the impact of malware traffic. We can see the behavior and choose the correct sites. We're currently testing secure access with Umbrella in order to secure access to core applications. It's a product that the user doesn't even know is there, even though it is protecting them. It's not hard on the equipment. And, for us, it centralizes everything, which improves productivity. 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. We are testing the Secure Access product with Cisco Umbrella to improve our connectivity with our users in order to secure access to the corporate applications. Cisco Umbrella is in the cloud, which is nice.

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."

"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."

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

"The security aspect of the solution, particularly the malware behind it, is excellent. That's something that really helped us out. It's not just a simple proxy that just blocks the insights of potential threats that come on behind it. They do malware detection and that helps us a lot."

"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."

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

"We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times."

"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."

More iboss pros

"The most valuable feature is that it secures our network against blacklisted or malicious websites."

"A single pane of glass saves time... This does have a lot of options available for us to see who's doing what, what trends, what errors. We can set up our alerting through it as well. It is definitely a great dashboard."

"The most valuable thing is how easy it is to deploy. We did it with 9,000 users at my last job, and it took a week to get to all the endpoints. Doing that without having to physically touch all those endpoints was very simple."

"The feature that we find most valuable is to be able to filter out those web requests that you don't want."

"Some clients only want DNS security, while others want more of the advanced features that it has available."

"It will protect, give you more robustness, and faster responses, compared to any firewalls or any of the proxy web servers."

"Cisco Umbrella is the first layer of security that protects me while surfing the net, identifying untrusted websites to prevent access."

"Any time someone went off the network, the AnyConnect client had the Umbrella agent built in, and it would realize when their computer connected that they were not on the corporate network. It would monitor and they would have pretty close to the same rules that they had to follow when they were in the office, regarding what kind of website browsing they could do."

More Cisco Umbrella pros

"The most valuable aspect of Zscaler Cloud DLP is its automatic DLP feature."

"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."

"SASE's most valuable features are proxy and content filtering."

"I like its ease of use. It has a single pane of glass for the ZIA and ZPA pieces. It is very manageable. It is also very easy to deploy for secure access, and it gives half-decent coverage for visibility in terms of what the users use and what data is being proxied through the access gateway."

"The most valuable features of Zscaler CASB are API integration and DLP."

"The most valuable feature is its seamless integration capabilities, streamlining the process by eliminating the need for extensive installations."

"The most valuable features of Zscaler Private Access are reliability, scalability, and availability."

"It is a stable solution."

More Zscaler Zero Trust Exchange Platform pros

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 solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."

"One thing I would like to see differently with their Zero Trust platform is that some of the AI aspects related to high-risk activities have more false positives."

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

"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."

"File integrity monitoring would be very advantageous as an additional feature."

"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."

"Sometimes, obviously, there are bugs."

More iboss cons

"With any Cisco product, it's the licensing side of things that needs improvement."

"There are some situations where we would like to block things for specific user groups. I know that Umbrella does that, but it's not that easy.... when you want a specific task for specific rules and policies for user groups, you have to go three levels down in the menu, and it's hard to find where you do that task."

"There are a couple of different pieces that have different portals. I know they're working on getting them all into one portal, but that's probably the biggest thing that needs improvement right now. It's not a single pane of glass yet."

"The product can be pretty expensive."

"This solution does not give us full, 360-degree protection."

"Customization for basic users can be complex, as it is targeted toward only technical users."

"I would like to see more integrability with other products."

"I would like for them to continue building on IPS and IDS functionalities."

More Cisco Umbrella cons

"We'd like to have two-factor authentication that is quite simple."

"SCMP support would be one of the biggest improvements in my opinion. More speed improvements are also required."

"User management can be improved."

"We have issues with the tool's maintenance and networking. It should be able to work in offline mode as well."

"There is improvement in enhancing proper manageability, policies, and logs. So, log management could be improved."

"I can't speak to any missing features."

"Price-wise, it is a costly product and it should be reduced."

"There is some issue while accessing the portal. It takes too long."

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."

"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."

"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."

"Cisco Umbrella is not a cheap product. However, it's not a matter of the cost; it's more a matter of the value of security. It is easy to measure this value when you have a security incident. I think the price is a good trade-off for a product that can help you avoid security threats."

"It has a reasonable price. It is certainly not as expensive as it used to be. It is in line with other offerings on the market. There are a number of different flavors of Umbrella. They could bring Umbrella SIG down a bit because its price is a little bit high for what it does, but I also understand why its price is high."

"Cisco has a model called ELA. With ELA, if you buy the solution you will have the complete security portfolio and you can pay it yearly or after three years, it depends on the contract."

"The licensing and pricing structure of Cisco Umbrella is in line with standard systems on the market, and we have no specific requirements in this area. Overall, we have found it to be an acceptable pricing model for our organization."

"Pricing depends on the automation requirements of the organization."

"The licensing part for Umbrella is really flexible."

"The price is fair, and the licensing cost is based on the number of users. We have seen a good ROI."

"The licensing fee is paid on a yearly basis."

More Cisco Umbrella pricing and cost advice

"Pricing for Zscaler Private Access is moderate. It's acceptable, though I can't give you the exact price currently. It's not too expensive, and on a scale of one to five, I would rate it a four out of five in terms of pricing."

"It is an auto-renewal subscription service."

"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 CASB is an expensive solution."

"Zscaler Private Access is extremely expensive."

"The cost is expensive. It depends on the number of users."

"The price is competitive."

"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."
