With iboss, whenever you turn on your laptop, the iboss agent automatically connects to the iboss cloud, enforcing all security policies. So with respect to the security side, it strengthens measures.
Senior Consultant Proxy Engineering at a financial services firm with 10,001+ employees
Deploying iboss leads to good return on investment, estimated around 70% to 80%.
Manager at Cyvogenix
I have seen some cost effectiveness from iboss; it has reduced certain support requirements, making it a more hands-off solution.
Managing Director
I have seen a return on investment, specifically in terms of time saved and needing fewer employees.
SVP IT at AS IT Consulting Pvt. Ltd.
Cisco is a big brand in the networking domain, but in security, they are pushing a lot and improving day by day.
Chief Technology Officer at Binary Global Limited
From my point of view, the biggest return on investment when using the solution is that it makes it a lot easier to delegate some of the tasks that were traditionally used, such as building policies on the firewalls and doing it through Cisco Umbrella.
Network Engineer at a tech consulting company with 501-1,000 employees
The biggest return on investment so far has been visibility, knowing what we have in our environment.
Cloud and data protection engineer at a university with 10,001+ employees
As a small team, Microsoft Defender for Cloud Apps allowed us to manage systems with just one or two people.
Manager, Information Technology Security Compliance at a manufacturing company with 201-500 employees
We have at least saved the costs we had from the Netskope solution this year.
Security and Continuity Manager at Rolinco NV

Sentiment score
7.4
Iboss customer service is fast and knowledgeable, though some desire better transparency and 24/7 availability. Scores range high.
Sentiment score
7.9
Cisco Umbrella's customer service is praised for expertise and professionalism, though some experience delays, particularly with email support.
Sentiment score
6.6
Microsoft Defender for Cloud Apps support has mixed reviews, with high technical proficiency but inconsistent responsiveness and communication delays.
They are very fast, responsive, and knowledgeable.

The quality of the support is fantastic.
Educational Technology Coordinator at a performing arts with 201-500 employees
We had promising discussions about resolving these issues, but no real action followed.
Network Administrator at a educational organization with 51-200 employees
I would rate customer support ten out of ten due to the excellent assistance throughout the POC process.
Manager Cyber Security Department at Mana
Cisco's support is fantastic, providing assistance when needed, especially during the initial installation process.
Director at Infosonik Systems Ltd
If I don't need to go to support all the time, that means the product is working fine, so I'm very happy with them.
Network Engineer at a tech consulting company with 501-1,000 employees
Their customer service is pretty good, but it's frustrating to go through three or four channels before reaching the right person.
Cloud and data protection engineer at a university with 10,001+ employees
The support is excellent, and the speed of response is commendable.
Solutions Architect at a university with 51-200 employees
There were instances where the engineers were knowledgeable and helpful, but at other times it felt like a ping pong game, with unnecessary transfers until the right person was found.
Manager, Information Technology Security Compliance at a manufacturing company with 201-500 employees
 

Scalability Issues

Sentiment score

Iboss scales efficiently, handling heavy traffic and large deployments, with swift resource adjustments and reliable performance for expanding organizations.
Sentiment score
8.1
Cisco Umbrella adapts seamlessly to user growth, offering scalable, cloud-based security with efficient centralized management and flexible licensing options.
Sentiment score
7.5
Microsoft Defender for Cloud Apps offers scalable, cloud-native security but may require extra resources for large-scale policy management.
They are also able to meet on-demand requirements based on your contract with them, and can easily provide adequate resources and scalability.
Senior Consultant Proxy Engineering at a financial services firm with 10,001+ employees
I would rate it a nine out of ten for scalability.
If I start seeing sluggishness or anything like that, I just reach out to my rep, and they connect with their dev team, typically resolving it the same day.
Educational Technology Coordinator at a performing arts with 201-500 employees
Cisco Umbrella scales incredibly with the growing needs of my organization.
Network Engineer at a construction company with 1,001-5,000 employees

Senior Network Engineer at Boys Town
For what I know about the log collector and how much data it can take in, it is super scalable and capable of handling high workloads.
Cloud and data protection engineer at a university with 10,001+ employees
Microsoft Defender for Cloud Apps is very scalable, provided you have the right subscription.
Solutions Architect at a university with 51-200 employees

Educational Technology Coordinator at a performing arts with 201-500 employees
We've experienced zero downtime.
Head of Cybersecurity at SES Water

Room For Improvement

iboss needs better integration, scalability, security, and support, with upgrades in performance, automation, dashboards, and access control.
Cisco Umbrella faces criticism for high pricing, complex integration, support delays, and usability issues, needing streamlined features and documentation.
Microsoft Defender for Cloud Apps needs improvements in pricing, interface, integrations, alert precision, documentation, and multi-cloud support.
It is not as intuitive as the rest of the platform.
Head of Cybersecurity at SES Water
iboss's single pane of glass console gives centralized visibility into web traffic, user activity, security policies, and alerts from one dashboard.
Manager at Cyvogenix
We also had a problem with a transition when we upgraded from one appliance of theirs to another, but their engineer lost a good deal of our data.
Network Administrator at a educational organization with 51-200 employees
Making it more flexible and easy to deploy, particularly when integrating with other technologies like Active Directory and proxies, would be beneficial.
Manager Cyber Security Department at Mana
The product can only shield a small area, making it less effective for larger spaces or multiple users.
Director at Infosonik Systems Ltd
I have to write an email to Umbrella support to get assistance, unlike the other products where I can call the Cisco technical assistance center and get an engineer.
CTO at Next Technologies Ltd
For data loss prevention, it would be useful to be able to drill down into the kind of data being transferred over CloudApp.
Head of Security Operations at a computer software company with 51-200 employees
Defender typically connects to Entra ID, but we have local users on the cloud for database access, SSH, or RDS, and there is nothing produced by Defender regarding those local IAM users.
Network Engineer at Apexon
Microsoft Defender for Cloud Apps would benefit if Microsoft allows users to fine-tune false positives, enabling us to dismiss alerts or make adjustments so that such things don't trigger multiple times in the future.
Security delivery analyst at a tech vendor with 10,001+ employees
 

Setup Cost

Iboss offers competitive, transparent pricing with comprehensive features, fitting security budgets better than pricier competitors like Broadcom and ZScaler.
Cisco Umbrella is deemed costly but valued for security, though license complexity and cost competitiveness could improve.
Enterprise users find Microsoft Defender for Cloud Apps affordable within bundles but expensive standalone, desiring more pricing transparency.
It offers the same features you would get from a vendor that charges 250,000 British pounds for a fraction of the price.
Head of Cybersecurity at SES Water
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.
Network Administrator at a educational organization with 51-200 employees
Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern.
Managing Director
We've bundled that with our firewall stuff and our VPN, which brings the price down and adds the ability to grow.
Senior Network Engineer at Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C.
The only cost associated is the license cost unless additional solutions need to be integrated with Umbrella, which would incur extra costs.
Director at Infosonik Systems Ltd
The prices need to be lower as the current pricing is exceedingly high.
Network Solutions Architect at a financial services firm with 10,001+ employees
The pricing for Microsoft Defender for Cloud Apps is acceptable.
Solutions Architect at a university with 51-200 employees
My organization is currently revisiting pricing, but previously, the cost was a bit expensive, yet comparable to other solutions with similar functionalities and features.
Manager, Information Technology Security Compliance at a manufacturing company with 201-500 employees
It's not the cheapest, but also not the most expensive, placing it in the mid-level range.
IT Architect at a logistics company with 10,001+ employees
 

Valuable Features

Iboss enhances security with Secure Web Gateway and Zero Trust Network Access, improving efficiency and supporting remote users.
Cisco Umbrella enhances network security with DNS protection, easy management, remote integration, and proactive threat detection for organizations.
Microsoft Defender for Cloud Apps offers seamless integration, real-time threat detection, and robust security features for comprehensive cloud protection.
The solution's mental health function can detect if someone needs help.
Head of Cybersecurity at SES Water
It's given us a lot more visibility into our computer assets that may be infected with viruses and also shows us people who have unusually large uploads or might be engaging in high-risk activities, such as searches or going to sites not categorized by their web crawler.
Educational Technology Coordinator at a performing arts with 201-500 employees
iboss was the best solution for us because, no matter what domain you were in, everything is under a single pane of glass, which is exactly what we wanted.
Managing Director
The DNS layer security provided by Cisco Umbrella is very effective for our security posture, offering us vast improvements in visibility over DNS queries and potential threats.
Manager Cyber Security Department at Mana
The most valuable feature of Cisco Umbrella is its DNS security.
Network Solutions Architect at a financial services firm with 10,001+ employees
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.
Chief Technology Officer at Binary Global Limited
It provides excellent suggestions and options for configuration; for example, it can track suspicious files getting uploaded to cloud resources on Azure based on their signatures, generating alerts for those files.
Security delivery analyst at a tech vendor with 10,001+ employees
The product recommends things that need to be blocked and allows for dynamic configuration, which cuts down on potential issues that might arise from going through lists and understanding what needs to be blocked.
Partner & Chief Executive Officer at a consultancy with 51-200 employees
The ability to sanction unsanctioned apps using Secure Score benchmarking, included in Cloud, is also beneficial.
Head of Security Operations at a computer software company with 51-200 employees

Cloud gateway has strengthened remote web security and now needs better Mac and ISP support
The problem our organization had is that iboss failed for the Mac devices. It is not able to give a successful agent for the Mac agents. That is where in 2025, we had to migrate to the Palo Alto-based platform. If your use case is for just Windows laptops,you can consider this platform as an option One issue is the data center resiliency part. In India especially, they are not tied up with the Tier 1 ISPs like Tata or Airtel; they were having Tier 2 ISPs and encountered many issues reaching few major sites that my organization depends on, and they were having problems that they could not fix quickly. They also lack a mechanism to route that traffic within their data center; rather, they ask customers to make a pac file change to route it to Singapore explicitly. It would be better if they route from their backend , i mean even if I send it to India DC, they should be able to route it internally to make that work; however, they fail to do that and ask the customer to route it in the pac file. Another suggestion is that in China, they do not have the proper setup; they used to have numerous problems with slowness and lack of premium circuits in China as well. That leads to multiple sites working slowly with latency-related issues. So the main issue is the ISP-related problems that need to be solved.

Secure browsing has protected users from DNS threats and improves malware defense
The major issue is that sometimes when you install the client, it shows you protected and displays that it is live with the backend servers and everything. However, in reality, it was not getting any feed from the main client and is just sending your traffic to open DNS, which sometimes causes an issue because the protection you have implemented can be breached by users. The primary thing that Cisco Umbrella lacked most of the time is their client. Previously, they had a separate Cisco client. Now they have merged everything into the Cisco Secure Endpoint client—one client for everything, for Cisco Endpoint, for Cisco AnyConnect, and for Cisco Umbrella, which they did probably in 2025.

Enforces dynamic policies and blocks risky behaviors to safeguard sensitive data
The fidelity of the signal in Microsoft Defender for Cloud Apps has been a challenge in some areas. There have been instances where the alerts generated have been false positives. A lot of work has to go into scoping and tuning the policies so that actual value can be achieved, especially when not doing outright blocks. When monitoring is the approach, it can be overwhelming for security teams to review all of the alerts and determine which ones require action. When a legitimate alert is found that requires action, the tools are available to take that direction, but it can take considerable time to determine if an alert is real or not, and that represents a problem. There is uncertainty about how well Microsoft is keeping up with the changing landscape of threats, as new artificial intelligence services and software as a service applications appear every day.
