Qualys VMDR and Microsoft Defender for Cloud Apps are top competitors in vulnerability management and cloud security. Qualys VMDR stands out with its strong scanning capabilities and integration flexibility, making it ideal for comprehensive vulnerability management. Microsoft Defender for Cloud Apps shines in environments heavily reliant on the Microsoft ecosystem, thanks to its seamless integrations and robust threat detection features.

Microsoft Defender for Cloud Apps excels in identity management, threat detection across cloud applications, and extensive Microsoft ecosystem integration, providing a seamless identity and security management experience.

Room for Improvement: Qualys VMDR could enhance report customization, API speeds, and cloud integrations.

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.

Continuous risk-based monitoring has strengthened incident response and vulnerability prioritization

I haven't explored Qualys VMDR's vulnerability lifecycle automation yet. One of my analysts mentioned that queries lack grouping operators in Qualys VMDR. From my experience, I would appreciate improvements in the query options in Qualys VMDR, specifically in the query-building process where I would need more features and operators. Additionally, we have been facing issues with Qualys on the cloud level. We cannot download the configuration profile from the cloud agent, and it is showing a pending action for download. During 2025, we noticed outages of Qualys a couple of times. I want to mention that there is an issue with receiving timely RCA deliveries. While this is not necessarily about the tool, it relates to support. The support has not been very responsive, and we are receiving RCAs a little delayed whenever we raise support cases or communicate with the TAMs. Additionally, the UI has a slight latency, which I and my team have experienced. They have also reported this latency issue when navigating through different pages.

Quotes from Members

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

Pros

"iboss is among the few products providing inline filtering where no application is needed on the device."

"The security aspect of the solution, particularly the malware behind it, is excellent."

"From a corporate perspective, I understand that it's important to keep the company data safe."

"Our primary use case for this product is DLP,"

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

"iboss is definitely very good in terms of service."

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

"The console is cloud-based, which is something I really appreciate."

More iboss pros

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

"It has helped identify areas where we should improve, make changes to improve, the reason why we should make a change, and the impact of making the change."

"The solution is helping a lot; we get very detailed reporting on security that really shows what users are doing, including what they've opened, what they're sharing, downloading, viewing, and when they are logging in."

"The major benefit is that it is a Microsoft tool, so if you're in a Microsoft ecosystem, this is the best tool that you can get in the market."

"The compliance capabilities of Microsoft Defender for Cloud Apps are quite extensive."

"We have seen a 35% to 45% cost reduction with this solution."

"There are a lot of features with benefits, including discovery, investigation, and putting controls around things. You can't say that you like the investigation part but not the discovery. Everything is correlated; that's how the tool works."

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

More Microsoft Defender for Cloud Apps pros

"Qualys VM has allowed us to know the vulnerabilities we need to prioritize based on the threat levels and the possible impact if there's an intrusion."

"Almost all of the features are great."

"The platform's most valuable features include its robust vulnerability detection capabilities and automated remediation workflows."

"It is quite easy to implement."

"I find most valuable to achieve a channel system and we can also use it to track when we actually close the ticketing of the sites, and in addition, it is quite easy to implement."

"The integrations for this solution are very good. I use a different product for virtual patching of vulnerabilities and Qualys integrates well with that product."

"The most valuable features are that it is a simple solution that makes scanning easy."

"I like the solution's web application security for scanning, the solution is flexible with good integration."

More Qualys VMDR pros

Cons

"It is stable, but due to growth, it can sometimes be less stable than wanted."

"The endpoint-type solution is an area that needs some improvement."

"I have heard they are doing DDoS filtering, but I am not certain if they are implementing it correctly."

"Sometimes, obviously, there are bugs."

"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."

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

"SSL decryption: We had issues with learners using apps instead of using web browsers."

More iboss cons

"Defender for Cloud Apps could come with more configured policies out of the box. Also, integration could be easier. Integration is moderately difficult because Microsoft hasn't developed a solution that unifies device onboarding and management. You have to use Intune to manage devices and Defender for Endpoint to enforce policies. They need to fix their integration, but I believe they will straighten it out by the end of the year."

"Licensing cost is a significant concern. With Defender Plan 1, Microsoft Defender for Cloud Apps comes with a pay-per-use model."

"The insights could be improved, especially in reporting."

"Sometimes, we'll get false positive alarms. For example, when a SharePoint path has no file sharing, but there is an external user, it will trigger an alarm that the file has been shared with an external user."

"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."

"Generally, the pricing can always be improved along with the management system."

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

"The documentation could be improved as it is not updated immediately when Microsoft makes changes. Users must wait a few weeks for the changes to be reflected in the documentation."

More Microsoft Defender for Cloud Apps cons

"There needs to be better documentation."

"They're still evolving their platform in terms of reporting capabilities."

"The tool needs to improve the adding assets and report generation features. I would like to see the policy scan of offline appliances in the product's future releases."

"When you want to cover yourself for scalability, you will be charged for the number you place on the scan itself."

"Integration could be better. When you think about scanning, it's not used just with this product alone but with other Qualys products."

"For a company with over 100,000 assets, there are challenges with scalability."

"Qualys VM could improve by having more skilled support personnel."

"Qualys Container Security can improve the interface. It could be easier to navigate and be enriched."

More Qualys VMDR cons

Pricing and Cost Advice

"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."

"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."

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

"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 pricing is fair."

"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."

"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."

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

"I'm not totally involved in the pricing part, but I think its pricing is quite aggressive, and its price is quite similar to Netskope. Netskope has separate licensing fees or additional charges if you want to monitor certain SaaS services, whereas, with MCAS, you get 5,000 applications with their Office 365. It is all bundled, and there's no cost for using that. You only have the operational costs. In the country I am in, it is a bit difficult to get people with the required skill sets."

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

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

"The E5 license offers everything bundled. People are moving to Microsoft because you buy one license and it gives you everything."

More Microsoft Defender for Cloud Apps pricing and cost advice

"An annual license for a single scanner costs around $3,000."

"The pricing and licensing for Qualys could be improved."

"It is more expensive than other products on the market."

"The solution is costly."

"It is a high cost product. Compared to the other solutions, it is around 15 to 20% higher in cost."

"Usually every implementation is different and the quote is in function of number of assets."

"Qualys VM is better suited for medium to large companies because the price can be too much for smaller customers."

"The product is more expensive than that of any other vendor."
