Sentiment score
7.0
Microsoft Defender for Cloud Apps enhances security and efficiency, offering significant ROI with up to 60% savings and streamlined operations.
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 when using Cisco Umbrella for me is the ease of use of the fact that we've deployed this with our Cisco VPN Secure Client, so every computer has the Umbrella module in it.
Senior Network Engineer at Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C.
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
I have seen some cost effectiveness from iboss; it has reduced certain support requirements, making it a more hands-off solution.
Managing Director
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.

The support is excellent, and the speed of response is commendable.

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
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.

Room For Improvement

Cisco Umbrella needs enhancements in reporting, integration, user-friendliness, protection, licensing, infrastructure, and support for an improved user experience.
iboss struggles with Mac support, integration issues, performance limitations, and needs improvements in security features and user configurations.
Microsoft Defender for Cloud Apps seeks enhanced pricing, integration, user interface, automation, and multi-cloud support, while improving insights and management.
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
It is not as intuitive as the rest of the platform.
Head of Cybersecurity at SES Water
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
Our iboss subscription access should be more secure with an OTP or VPN etc.
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

Cisco Umbrella's pricing is fair yet varies, offering value in security coverage with opportunities to bundle for discounts.
Iboss offers competitive and transparent pricing, often cheaper than Broadcom and Check Point, despite annual cost increases.
Microsoft Defender for Cloud Apps is seen as cost-effective for enterprises within Microsoft ecosystems, despite standalone pricing concerns.
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
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
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

Cisco Umbrella offers DNS-based protection, ease of use, and integration, enhancing productivity, security compliance, and visibility across networks.
iboss provides advanced security features, seamless cloud management, and scalability with user-friendly integration and robust threat protection capabilities.
Microsoft Defender for Cloud Apps integrates well, offering threat detection, management ease, shadow IT discovery, and robust security enhancements.
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
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
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

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.

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.

Deployment has been seamless with insightful data categorization and enhanced control
The features of Microsoft Defender for Cloud Apps that I have found most valuable include the overall portal view, with bubble graphs which give us insight into what goes where in the categorization, nowadays with Generative AI but all kinds of categorization, collaboration, etc. That central view of the portal is very useful for us. The impact of Microsoft Defender for Cloud Apps on our organization's ability to assess and manage app related risks has been significant because we have more visibility. Therefore, we can add more control, and we have already done so. This was not possible in the old solution, in the old CASB solution with Netskope. We now can see on the spot, and we do that almost weekly, what the end users are utilizing, which cloud providers or cloud apps they're using. The visibility into OAuth apps provided by Microsoft Defender for Cloud Apps is very good. The visibility into risk and risk management of our organization's Generative AI apps is very nice, as you can choose the category Generative AI and then see exactly what traffic has been going to and from Generative AI in the cloud. This makes us very insightful on what is used within the company. We have some policies on blocking specific Generative AI, and we use within our company one particular AI part, which is CoPilot of Microsoft. In this way, we can see what the end users are using other than CoPilot, and that makes us more in control. The effectiveness of the integration of Microsoft Defender for Cloud Apps with Defender XDR and defending against SaaS attacks is very intuitive. It works immediately if we create a new policy or in Purview or in Microsoft Defender for Cloud Apps, or when we make an app unsanctioned by blocking it, then it is almost immediately, or at least within a couple of hours, effective on all the endpoints where the EDR is running. This gives us much better control over things than before.
