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.

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.

Cloud-based platform simplifies device and data center management

I find it to be good. The solution is cloud-based with the latest inspection engines, which I find to be amazing. We are less dependent on data centers and device management, which reduces our efforts significantly. It improves our device management, data center management, and updating devices. We need fewer engineers for this management, and it reduces time and efforts for data center management, device upgrades, and IT support.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The solution has massively improved our security posture, giving us full visibility into what our staff does online."

"It was a very easy product to install. It can be deployed very fast."

"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."

"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."

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

"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."

"Its initial setup was straightforward."

"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."

More iboss pros

"The most valuable feature is the website protection capabilities because it prevents end-users from entering bad sites that potentially have malware or could be used for phishing."

"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."

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

"My overall rating for Cisco Umbrella is ten out of ten."

"We run a real lean networking team, and cloud deployments are super easy."

"Reports provide insight into internet usage and information helpful in creating QoS rules."

"Cisco is a very efficient and on-point solution that controls the whole network and settings on one page. We can monitor the entire network."

"Improves security through DNS visibility, which can block malware, phishing, C&C, etc."

More Cisco Umbrella pros

"Yes, it is very stable. I have never seen it go down, not once."

"I like the web filtering capabilities."

"This secure connection allows users to connect to the Zscaler VPN and access the resources on the office network, making it a highly valuable component of our system."

"It is easy to use."

"It does the job. What it is needed for. I can use it for VPN, I can use it for secure connections, I can use it as a firewall. So the solution does the job."

"The most valuable features are the File Type Control and SSL bypass policies. We"

"The most valuable feature is its ability to establish connectivity for remote users and remote endpoints. It offers a high level of granularity compared to typical VPNs, which also encapsulate a lot of I/O."

"Sandboxing, DLP, and SSL inspection engine are the most valuable features of Zscaler SASE."

More Zscaler Zero Trust Exchange Platform pros

Cons

"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."

"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."

"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."

"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."

"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."

"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."

More iboss cons

"Client delivery and client updates should be improved. Client delivery was not as easy as expected. Another area for improvement is the integration of escalation procedures for security issues."

"Security, overall, can always be improved."

"Cisco Umbrella could be improved by making the policies more granular, as in some cases, it's difficult to find the correct link to open a specific site securely."

"A feature I would appreciate seeing enhanced in Cisco Umbrella would be the ability to add or remove agents that we have, instead of just relying on how long the devices have been connected to the platform."

"Its price could be better."

"We would like them to add more features to Cisco Umbrella."

"It should have a real-time malware classification engine. It should check the malware on the website. It would be good if it had a real-time malware check for the websites because currently, it just compares the DNS queries of the blacklist. It should also have malware control over file execution and the types of files that the users are allowed to download."

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

More Cisco Umbrella cons

"Sometimes, support takes time since the solution has some bugs that need fixing."

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

"The connectivity monitoring part should be included in the core license without any extra charges."

"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."

"There aren't really any missing features that I have witnessed."

"The only issue with Zscaler Cloud DLP is that it only gives you DLP protection from web traffic, which is flowing out, while a full-blown DLP solution such as Forcepoint or Symantec gives you DLP coverage for multiple channels. Zscaler Cloud DLP doesn't give you coverage for email, fax, and USB channels, and this is the only challenge or room for improvement in the solution. It's just an extension on top of what you're buying on the proxy, so it's just an added layer, and it doesn't cover DLP on a very broad level. I'm unsure if Zcaler is in the business of competing with a full-blown DLP solution, and if there's a plan to expand the features of Zscaler Cloud DLP beyond the web channel because you'll have to deploy a full-blown agent for it. I'm unsure if this is on the cards because the solution is just an added layer that you get with your proxy. I've asked the Zcaler team whether there's a plan to go full DLP in the future, but I didn't get a positive response. There isn't any feature I'd like added to Zscaler Cloud DLP currently, because anything you could think of that should be in cloud or SaaS solutions is already there, except for machine learning, as it's the only functionality that seems to be lacking in the solution. Machine learning is an additional policy available in other DLP solutions in the market, but my team didn't find it in Zscaler Cloud DLP."

"The product is not reliable."

"The pre-defined dictionaries could be improved."

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."

"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."

"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."

"The price could be lower."

"Licensing fees are paid on a yearly basis."

"Cisco is expensive. For example, we are looking at Nexus Dashboard, and it's costing about 250,000 euros. I ask, "What do I get from it?" I'm still not convinced that we have to spend on it, so pricing is a problem."

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

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

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

"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."

More Cisco Umbrella pricing and cost advice

"Zscaler Private Access can be an expensive solution, depending on the license type you will purchase."

"It is an auto-renewal subscription service."

"It's an affordable solution"

"Zscaler Cloud DLP is moderately priced. We pay around 2 million rupees per year."

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

"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."

"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."

"The price is competitive."
