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

"Its initial setup was straightforward."

"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."

"The console is cloud-based, which is something I really appreciate."

"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."

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

"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."

"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."

"Technical support is pretty sharp and very responsive."

More iboss pros

"The most valuable features for us include tenant lock, content filtering, and DLP solutions, looking for PII and information being exfiltrated."

"For me, it's important that I get a connection to my corporate network in a secure and fast way. This product just runs in the background and doesn't need any attention. For me, as a user, it's perfect."

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

"The interface is well organized, so you can easily find everything. Even if you don't have much experience with Cisco, you can easily navigate the solution and find your way around. Everything has been done well, from the deployment to monitoring."

"The most valuable features are the dashboard, visibility, and reporting capabilities. Our customers can see how much Umbrella is protecting their organization. If you don't know what you've got, you can't protect it. With Umbrella, you get the visibility and see the protection that it's providing. We can get PDF reports on a weekly basis of any malware activities and any denial of service or command-and-control-type activities."

"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 security and access control features."

"The best possible thing is that it is very easy to deploy, easy to configure, and very fast to get onboarded with a customer because this is a cloud-based service."

More Cisco Umbrella pros

"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 most valuable feature of Zscaler Private Access is we do not have to connect to a VPN, it is seamless. It is more convenient for us because we use one agent to cover the internet and VPN access."

"It is a very scalable solution. Scalability-wise, I rate the solution a ten out of ten."

"The platform offers advanced threat protection features and embedded AI/ML capabilities, making it more proactive in blocking threats."

"The product’s most valuable features are inbound and outbound scanning and API control."

"The most valuable features of Zscaler Private Access are its ability to integrate with multiple IDPs and application segmentation."

"The ZPA is a unique feature which offers VPN along with all the additional security needed."

"The scalability is pretty good."

More Zscaler Zero Trust Exchange Platform pros

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."

"I'd like to see them accelerate development on the security side, particularly around data loss prevention."

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

"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."

"To scale up, a new iboss Node Blade Chassis must be purchased."

"The dashboards for local use could be better."

"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."

"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."

More iboss cons

"It would be good if the more complex versions of Umbrella are simplified so that we can offer them in a more standardized way. We, as a telco, do not operate the same as a traditional integration partner would, who can sell all its services. We try to have a standardized approach as much as we can so that we can sell the solution with as many services added to it as possible. If you look at the structure of businesses in Switzerland, 95% of them have 10 persons or less, and they do not have a security specialist. Therefore, the higher the automated and standardized features, the better it is for them."

"If we're trying to deploy it to a Mac through Meraki, it's impossible. The method of deployment for a Mac, and the features available in Meraki, are not compatible at all."

"The product can be pretty expensive."

"One of the issues with Umbrella is as you get into endpoint detection and response, such as EDR point solutions, some of them will not integrate well with Umbrella. Sometimes when you want to use technology, such as Always On VPN, it will not work. There are some looming issues as one type of technology starts to crossover with Umbrella. That is the challenge and Umbrella should find a way to be more compatible with some of the endpoint response solutions that are coming out on the market."

"Sometimes there are some lags, and I have to refresh multiple times to access parts of the dashboards. Sometimes the dashboard pages crash and I'm not sure why, so that's one area for improvement."

"Although Cisco Umbrella has an excellent global network footprint, there is still room for improvement and growth in this area. Additionally, there are bandwidth limitations associated with the connectors that need to be addressed. To be a viable solution for larger offices, Cisco Umbrella must continue to expand and improve its capabilities in these areas."

"Cisco Umbrella can be improved in terms of limited coverage and wind vulnerability. The product can only shield a small area, making it less effective for larger spaces or multiple users."

"The locks and management could be better. The product is fairly new, and it may take some time to get all the features up and running."

More Cisco Umbrella cons

"The pricing for Private Access seems to be on the expensive side, and I believe they should consider making it more competitive with other solutions."

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

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

"The tool must provide IP-blocking features."

"The product must allow users to check logs for an entire year in the local console."

"In the next release, I would like to see RE2 Regex supported."

"There could be a feature to view the VPN tunnel activities in terms of configuration."

"Setup is a bit complex because there are many steps that need to be taken before onboarding and activating the solution."

More Zscaler Zero Trust Exchange Platform cons

Pricing and Cost Advice

"We have not priced the solution recently, but they were competitive with other vendors in the past."

"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 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 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."

"The product is pricey compared to Cisco Firepower."

"Its value exceeds its pricing."

"In the region I'm from, that of EMAR, Europe, the Middle East, Eastern Asia and Africa, our organizations do not have many liquid cash assets, so the price could be better."

"We have a security Enterprise Agreement with Cisco, so the pricing is good."

"Cisco should make the solution cheaper."

"In my opinion, Cisco Umbrella now has a good price in the basic packages. When it comes to Cisco Umbrella SIG Essentials package and Cisco Umbrella Secure Internet Gateway (SIG) Advantage package, it depends on whether the project has a good price or not"

"The price depends on the use case, and it's a bit linear. But it depends on the customer's strategy and how Cisco plans to optimize the costs."

"You get what you pay for if you break the solution up into tiers."

More Cisco Umbrella pricing and cost advice

"Zscaler SASE software is quite expensive compared to other solutions"

"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."

"The product has reasonable pricing."

"The pricing is expensive and on the higher end. Honestly, in my opinion, it is not worth the price."

"There is definitely an ROI."

"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 is a bit expensive."

"My company is a Zscaler Private Access partner, so the customers pay for the license fees."
