Executive SummaryUpdated on Jan 4, 2026

Microsoft Defender for Cloud Apps and Cloudflare One both compete in the cloud security category. Microsoft Defender for Cloud Apps appears to have the upper hand due to its seamless integration within the Microsoft ecosystem and comprehensive security features.

Features: Microsoft Defender for Cloud Apps provides robust threat detection, data protection, and investigatory capabilities. Its integration with existing Microsoft tools, including Shadow IT discovery, makes it highly appealing. Cloudflare One is known for its user-friendliness and zero-trust architecture, with effective DDoS mitigation and straightforward integration for ease of management.

Room for Improvement: Microsoft Defender for Cloud Apps could improve integration with non-Windows systems, enhance reporting capabilities, and optimize its user interface. Users mention delays in policy application and false positives as issues to address. Cloudflare One could benefit from improved documentation, better support, and a more streamlined setup process, as rule management can become intricate.

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.

Cloud security has improved remote access and has reduced costs for smaller client sites

I have used Cloudflare One's Identity-Aware Proxy, and it is quite straightforward from what I have seen so far. The app registration on the Azure side integrates fully into Cloudflare, and I am very satisfied with that part because it is easy to set up. The integration of Cloudflare One's Secure Web Gateway and Zero Trust Network Access works without any issues. That part is pretty automatic, and if you complete the rest of the setup, it comes together by itself with no issues from my side. What makes it nice is that we can actually start replacing on-site firewalls at this stage for the smaller clients because it does not matter if they go to a coffee shop or work from home; they are still secured by the same connection. The hops get shorter and you get better latency. We have done testing to see if it is better. One thing that we did notice with our proof of concept with our current client is that they have people connecting from the UK. When they used their previous VPN solution, uploading CAD drawings and other files to the server took a long time. They mentioned that it is much quicker on Cloudflare One's solution. I definitely believe that is part of the improved performance, and I am satisfied with that as well. What is nice about Cloudflare One is that it makes the setup easier and also easier to train technicians to maintain it. Compared to legacy systems, we do not need to get fancy firewalls in place that are costly. That is definitely also a cost-saver with Cloudflare One.

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.

Quotes from Members

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

Pros

"The iboss system is highly reliable. The false positive rates are small compared to some other systems we've experienced through other partner agencies who use competing solutions."

"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."

"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."

"Technical support is pretty sharp and very responsive."

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."

"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."

"iboss is easy to use despite its complexity. Multiple engineers manage it, but it's significantly more straightforward to administer than traditional VPNs and web proxies."

"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."

More iboss pros

"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."

"The best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."

"It is a stable solution."

"Clover is the best product globally."

"The blocking feature is very good."

"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."

"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."

"It will take the blow rather than our applications should an attack occur."

More Cloudflare One pros

"The most effective features for data protection are data loss prevention (DLP) and data classification."

"Defender for Cloud Apps has given us good visibility regarding what we've allowed in our environment until now. It helps us to know our inventory, understand what our customers are using, and steer them toward safer practices."

"The raw logs that come directly from Microsoft Defender for Cloud Apps contain all the data I need, and the ability to track activities happening on cloud applications and the alerts provided is an interesting aspect."

"It does a great job of monitoring and maintaining a security baseline. For us, that is a key element. The notifications are pretty good."

"I would rate it a ten because I have not experienced any stability issues so far with Defender for Cloud Apps."

"Better logging allows us to find problems and take appropriate steps to lock them out."

"The product helps us with privileged identity management to control who has access to what and for how long."

"We have become more aware of what services our users are using, how often they are using them, and what data is being sent out of the organization and to which services. So, it is really a lot about visibility and helping us make decisions based on that. It drives some of our policy decisions for adding extra security controls."

More Microsoft Defender for Cloud Apps pros

Cons

"Iboss is growing so fast that it is often hard for them to keep up with the challenges."

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

"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."

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

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

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

"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."

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

More iboss cons

"They don't have a person to provide support for customers using the solution under their free plan."

"Lacks a VPN feature to provide a secure connection to the data center."

"Cloudflare DDoS has poor technical support."

"Operating and tuning the product is difficult."

"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."

"For the topic of improvement, providing some training material is one of my suggestions."

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

"The response time for support must be reduced."

More Cloudflare One cons

"The technical support team has room for improvement."

"The areas of Microsoft Defender for Cloud Apps that need improvement are related to IAM, as they do not provide much support for local users."

"This service would be better if it had a separate license, only for this service, that could be used to track usage."

"Microsoft Defender for Cloud Apps' initial setup was quite technical but we were prepared. The time of the implementation depends on the job and how many users are being set up."

"It takes some time to scan and apply the policies when there is some sensitive information. After it applies the policies, it works, but there is a delay. This is something for which we are working with Microsoft."

"We sometimes get errors when we create policies, which is somewhat annoying because some policies stop working due to misconfigurations. We find this challenging because it limits our options for troubleshooting an issue."

"The graph displayed in the Defender portal mostly doesn't capture the full picture as we see in endpoint-related or identity-related alerts; we can see a complete graph of what is happening there, but Microsoft Defender for Cloud Apps still falls short in capturing that whole aspect in the graph."

"There have been instances where the alerts generated have been false positives."

More Microsoft Defender for Cloud Apps 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."

"It is expensive compared to one of its competitors."

"The overall pricing for iboss is very competitive and transparent."

"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."

"It is probably in line with other solutions, but I do not deal with the financial side."

"The prices are slightly expensive."

"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"The solution is not that expensive."

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."

"The solution's pricing lacks transparency."

"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."

"Cloudflare Zero Trust Platform's pricing is good."

"Where we are right now, this is an acceptable pricing. I would like to see more transparency given to the end user. The end user given to us is via the cloud service provider. There are different programs and license models. Some include this, and some include that. It is all over the place. There can be a little more consistency or simplification in the pricing so that your parts list is not ten pages long, and you are not trying to determine, "If I have an E3, does this cover that?", or "Do I need to pay separately for the license?" Simplification would probably be better."

"It has fair pricing. You pay for what you get. As far as I know, there are no costs in addition to the standard licensing fee."

"We have an educational licensing agreement. It's a customer agreement for multiple years."

"The product's pricing seems fair."

"It is a little bit expensive. When you want to have the complete package with Office 365, Defender, and everything else, it is expensive."

"The pricing is in the middle. It isn't too cheap or expensive compared to other antivirus or security products. It is priced according to industry standards."

"The pricing is a little bit high but right now, we are okay with it because of the compatibility with Office 365, Teams, and Azure AD."

"Our clients normally use the Microsoft E1 licensing, which is renewed yearly."
