Room for Improvement: Qualys VMDR could enhance report customization, API speeds, and cloud integrations. The interface can be updated to ease handling false positives and integrating IoT and SCADA systems. Microsoft Defender for Cloud Apps requires better integration with non-Microsoft environments, reduction in false positives, and a simplified deployment process. Improved reporting for granular visibility and handling of multi-cloud environments are suggested improvements.

Ease of Deployment and Customer Service: Qualys VMDR offers diverse deployment options, including on-premises and hybrid cloud, providing flexibility for organizations.

Managing Director

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.

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

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

"Technical support is pretty sharp and very responsive."

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

"Granular setup, which was able to set different levels of filters using the OUs in the AD."

"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."

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

"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."

"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."

More iboss pros

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

"It gives our clients a sense of confidence that in case there are activities on some of their applications, they will get an alert and the issue will be mitigated, based on the action that has been set."

"Microsoft Cloud App Security brings them together onto the same platform from a security standpoint, and the application can run seamlessly across different clouds, which helps."

"The solution does not affect a user's workflow."

"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."

"The favorite feature of Microsoft Defender for Cloud Apps is the categorical blocking capability, which appears to be fed from Microsoft Security Intelligence feeds that seem to be better than other solutions and allows for dynamic configuration, cutting down on potential issues from manually managing block lists."

"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 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."

More Microsoft Defender for Cloud Apps pros

"This is one of the best products I have worked with so far."

"This is one of the best products I have worked with so far. I like the power of Qualys, and it's a better solution because you can scan a compact file, a BIT file, or batch files. The product already knows what's happening inside, and you don't need to expand the package. Tenable will do the same thing, but you need to have a package issuance claim. With Qualys, we can immediately understand the file, even a compact file. If there's some kind of discovery or incident, you will know what happened in the environment."

"The initial setup is straightforward."

"Qualys VMDR provides a real-time response and reporting feature, which is excellent."

"Qualys VM had a recent upgrade and the newer version is supporting the cloud."

"If you are familiar with or have hands on experience with Qualys Asset Inventory, this is a better tool, as it will give you in-depth details of all the assets and the managing inventory will be better, and it will also give you advanced features compared to those of other inventory tools."

"If you are comparing Nexpose and Qualys, I would prefer Qualys."

"What I like about Qualys VM is the dashboard presentation. It's very good."

More Qualys VMDR pros

Cons

"Fold that in with the risk intelligence they're getting from all of the different subscriptions they are a part of. Now, these security companies subscribe to things like emerging threats, databases, etc. You can fold all this intelligence to decide what's happening on an endpoint. I would love to see them start moving into that space. That would compete directly with Microsoft. Maybe that's why they haven't. Having that ability native within the solution would be great. The other area in which I would love to see improvement is more detailed descriptions of why they block websites."

"The dashboards for local use could be better."

"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."

"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."

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

"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."

"File integrity monitoring would be very advantageous as an additional feature."

"Sometimes, obviously, there are bugs."

More iboss cons

"I believe it's only set to be integrated with Microsoft Defender for identity and identity protection. I would like to see it available for use with something like Office 365 Defender."

"Sometimes the support is actually lacking."

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

"I would like more customization of notifications. Currently, you either get everything or you get limited information. I would like to have something in between where we can customize the data that is included in notifications."

"They should continue integration with all other Microsoft security-related products."

"There are some features, such as user navigation content filtering, that are disabled by default, and it probably makes sense to enable them by default."

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

More Microsoft Defender for Cloud Apps cons

"Qualys VMDR could improve in reducing the occurrences of false positive vulnerabilities."

"Regarding improvement, compliance features haven't been utilized much."

"Support could be a little bit faster."

"The reporting needs improvement. It should generate much more stuff like field reports."

"Every time they make a change, it's not always super smooth, and it's a little quirky with bugs sometimes."

"The customer support is very bad; when we submit a ticket, we do not get a response immediately."

"This solution could be improved by extending the agent capabilities to different operating systems including Mac and Linux. We would also like the capability to easily check for vulnerability in assets in the IOTs."

"There's a need to upgrade or fix the potential vulnerability rate. Around 20,000 potential vulnerabilities were showing in Qualys VMDR, but none of the other tools showed them. When we checked, it wasn't the case. Support explained that even small issues were being counted as vulnerabilities, causing issues in our audit. So, the security features could be improved to identify vulnerabilities accurately."

More Qualys VMDR cons

Pricing and Cost Advice

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

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

"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."

"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."

"The pricing is fair."

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

"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."

"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."

"We are an MST and we do not pay for the solution. However, the price of the solution could be better."

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

"It has pretty good pricing."

More Microsoft Defender for Cloud Apps pricing and cost advice

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

"They have recently changed the pricing model, which is now better than it was before."

"The solution is reasonably priced for the value it provides."

"Qualys VM is quite expensive. It's a subscription-based license, and it's yearly. Right now, it's open for me, and I don't have any limitations or caps on the licenses. They are seeing if the product is viable for 4500 users. I can add as much as I want, and at the end of the subscription, they'll let me know how many licenses were actually used and bill me accordingly. On a scale from one to five, I would give their pricing a three. It's still expensive."

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

"Qualys Virtual Scanner Appliance isn't expensive right now. But the price for their product bundles could be better."

"The pricing is very competitive."

"Qualys is cheaper and more affordable than other solutions."
