Executive SummaryUpdated on Sep 28, 2025

Microsoft Defender for Cloud Apps and Cloudflare One compete in cloud security management, each offering distinct advantages. Microsoft Defender for Cloud Apps has the edge due to its robust threat detection and comprehensive integration with Microsoft services, making it highly valuable within the Microsoft ecosystem.

Features: Microsoft Defender for Cloud Apps provides seamless integration across different clouds, robust threat detection, and comprehensive security posture insights. It excels in managing cloud environments and integrates well with other Microsoft services, offering unified solutions. Cloudflare One offers ease of use, strong DDoS protection, and a user-friendly interface, making it particularly appealing for simpler setups and those needing efficient deployment without extensive configuration.

Room for Improvement: Microsoft Defender for Cloud Apps could improve integration with non-Microsoft products, enhance macOS support, and provide better reporting capabilities. Some users experience occasional false positives and desire more seamless integration across multi-cloud and hybrid environments. Cloudflare One users report challenges with documentation, onboarding complexity, and limited support for free plans. Improved insight into WAF rules and streamlined support processes are also needed.

Ease of Deployment and Customer Service: Microsoft Defender for Cloud Apps offers flexibility in hybrid and public cloud environments and benefits from its integration within the Microsoft ecosystem, facilitating smoother deployment. While technical support is generally positive, responsiveness varies. Cloudflare One is notably straightforward in public cloud settings, though initial setup can be confusing. Its technical support is generally favorable, yet lacks depth in the free-tier support offerings.

Pricing and ROI: Microsoft Defender for Cloud Apps is often bundled with Microsoft’s E3 and E5 licenses, providing a cost-effective solution within a broader Microsoft context, though its licensing model may be considered complex and costly for smaller enterprises. ROI is demonstrated through its prevention capabilities and reduced operational overhead. Cloudflare One offers competitive pricing, especially given its security benefits. Despite a sometimes opaque pricing structure, its ROI is viewed favorably due to the competitive costs and straightforward DNS management.

It's easy to roll out, and their understanding of our business made it seamless

One aspect we value about iboss is its simplicity. Their customer service is brilliant, and they are super responsive and knowledgeable. It's easy to roll out, and their understanding of our business made it seamless. We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times. The user interface is highly intuitive. Our IT team picked it up with minimal training. It's arranged so that it's easy to find where things are. Another advantage is the single pane of glass console, which gives you visibility into what's happening. We're not fully there yet because we haven't implemented zero trust, but we're excited about the possibilities from the demos we've seen. We launched a POC of iboss' ChatGPT Risk Protection feature two weeks ago. AI is a great tool, but you need to be careful what you put into it. My biggest fear is employees inputting sensitive corporate information or customer PII data into one of these chatbots. I was impressed by our trial of the feature. It's exactly what we wanted. Now, when a user goes to ChatGPT, there's a banner warning them not to share information, and we can block conversations containing customer data like bank details and email addresses. I don't want to stop people from using it, but we need visibility. We've only tried it on a test group of 15 people. You can configure it to look for specific keywords or integrate it with your DLP policy if you have that configured

The solution enables seamless security management and fosters a learning environment

Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions. For the solution stopping us for e-learning, I appreciate the concept yet need more resources or courses in Mexico, preferably in Spanish. Certifications are easy, however, I require more real-world environments and instructors.

Integration with existing cloud workflows has simplified compliance and threat detection

Licensing cost is a significant concern. With Defender Plan 1, Microsoft Defender for Cloud Apps comes with a pay-per-use model. Each feature has its own pricing when activated on VMs. For example, the vulnerability assessment has separate pricing, the base model including encryptions has separate pricing, and the compliance features have separate pricing. This applies to each VM and Azure resource individually. It is not straightforward where you can take one license and apply it to everything. Each feature has its own pricing model which can be tedious, as the costs keep accumulating. The only lacking feature currently is XDR (extended detection and response). Apart from that, I have only positive experiences with the whole Microsoft suite, except for the pricing structure.

Quotes from Members

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

Pros

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

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

"We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times."

"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."

"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."

"Its initial setup was straightforward."

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

"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."

More iboss pros

"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."

"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."

"Clover is the best product globally."

"Cloudflare is by far the most effective solution that I have come across."

"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."

"The solution has different options that can be used to differentiate DDoS attacks."

"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."

"I'm very satisfied with the environment and the dashboard."

More Cloudflare One pros

"The feature that helps us in detecting the sensitive information being shared has been very useful. In addition, the feature that allows MCAS to apply policies with SharePoint, Teams, and OneDrive is being used predominantly."

"The most valuable feature is the seamless integration across different clouds."

"If your business requirements are relatively simple, it can get the job done."

"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."

"Shadow IT discovery is the feature I like the most."

"The integration within the entire Defender suite is highly valuable because it allows for communication between different components and offers pretty decent correlations."

"In Microsoft Defender for Cloud Apps, there is an option to enable files. Once you enable that, it will give you all the files in your organization and where they are located in the cloud... That feature is very useful for investigation purposes."

"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

"The dashboards for local use could be better."

"Its pricing could be better."

"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."

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

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

"The reporting feature needs improvement. It doesn't give you the expected results. It is quite difficult to get the specific reports needed, and it is not as intuitive as the rest of the platform."

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

"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."

More iboss cons

"Cloudflare DDoS has poor technical support."

"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."

"The software has automated alerts, but the automated alerts are not available in the mobile app."

"The onboarding process can be improved a little bit."

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

"Our subscription plan for the solution has a limitation of bot signatures."

"Our customers no longer use Cloudflare because its service is subpar."

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

More Cloudflare One cons

"The product is very good so far, however, it would be better if it could include more up-to-date threat protection."

"They need to improve the attack surface reduction (ASR) rules. In the latest version, you can implement ASR rules, which are quite useful, but you have to enable those because if they're not enabled, they flag false positives. In the Defender portal, it logs a block for WMI processes and PowerShell. Apparently, it's because ASR rules are not configured. So, you generally have to enable them to exclude, for example, WMI queries or PowerShell because they have a habit of blocking your security scanners. It's a bit weird that they have to be enabled to be configured, and it's not the other way around."

"There are challenges with detection and there are challenges with false-positive rates."

"In the future, I would like to see more plug-and-play capabilities that use AI to tell you what needs to be done. It would be helpful if it scanned our devices and made security suggestions, on a configuration basis."

"Defender could integrate better with multi-cloud and hybrid environments. It requires some additional configuration to ingest data from non-Azure environments and integrate it with Sentinel."

"I want them to enhance in-session policy."

"I would like for it to be available on Mac and for it to support all of the features of Microsoft financing products. It is really for Windows."

"The insights could be improved, especially in reporting. While it is possible for me to see the usage from different cloud apps, determining if critical data has been uploaded or if it is just normal transport data is difficult."

Pricing and Cost Advice

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

"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."

"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."

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

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

"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."

"The solution is not that expensive."

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

"The prices are slightly expensive."

"The solution's pricing lacks transparency."

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

"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."

"We utilize the Microsoft E5 licensing, which encompasses the entire Microsoft suite; however, it is costly."

"It has pretty good pricing."

"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."

"Its pricing is on the higher side. Its price is definitely very high for a small-scale company. As an enterprise client, we do get benefits from Microsoft. We get a discounted price because of the number of users we have in our company. We have a premier package, and with that, we do get a lot of discounts. There are no additional costs. It only comes in the top-tier packages. Generally, the top-tier license is the best license that you can get for your organization. If you want, you can buy it separately, but that's not a good idea."

"This product is not expensive."

"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."

"Microsoft offers bundle discounts and a pay-as-you-go option."

"The price could be better and should be reconsidered."
