Centralized security testing has improved vulnerability remediation and compliance reporting
I recommend more enhancements focusing on penetration testing for both SSL over HTTP and non-SSL over HTTP, specifically targeting the RCP Rich Client Platform and Equinox frameworks that allow on-premises desktop applications to be tested simultaneously. I believe those would significantly improve the tool in the future. I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities. Once we build this installer—rather than just working on the codebase—sometimes, we face gaps considering the build parameters and conversions to the installer. Identifying those gaps is an area that could use improvement after the installer or desktop application testing, which would be beneficial. That is the only reason; otherwise, I could easily rate it a ten out of ten given its smooth operational process.

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

"We have seen clear compliance and risk control outcomes more than other operational metrics, including fewer process gaps during documentation and safety checks, strong consistency in following protocols for handling, traceability, and staff awareness, better audit readiness, a lower chance of procedure errors, and faster escalation when something appears out of standard, which is very important for us in the healthcare sector."
"I think the best features that Nucleus Security offers are purely the faster remediation to dev tools, which is crucial for managing, prioritizing, and fixing vulnerabilities while helping operational pipelines run these vulnerability management tools."
"Qualys VMDR has positively impacted my organization by reducing vulnerability exposure time through faster detection and patching, and it has improved compliance reporting with accurate and up-to-date data."
"The most valuable feature is that this solution is very lightweight."
"Qualys VM's best features are vulnerability management and customizable scoring."
"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 process of defining and discovering scans is organized efficiently."
"The biggest benefit is from a security operations perspective, where we are able to drive our security posture upwards by remediating any discovered vulnerabilities."
"Qualys VMDR provides a real-time response and reporting feature, which is excellent."
"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."
 

Cons

"I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities."
"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."
"Regarding improvement, compliance features haven't been utilized much."
"Qualys should improve their customer experience. They need to improve the tech support experience and the turnaround time."
"The price could be better. Asset view is still a legacy feature. I'm not able to extract the information about the asset with complete details. It would be better if they fixed that in the next release. I know Qualys is already working on it, so I'm hopeful it will be available in the next five or six months. That would be something that's changed where I seek improvement."
"It's not very user-friendly at times and requires in-depth understanding. So, a layman or someone new to Qualys won't be able to easily understand it. You need education to use the solution."
"Certain integration factors between different options could be improved."
"Its integration with ServiceNow and other similar products is complicated and can be improved."
"If you're not overly experienced and you're looking for something in their management, it can sometimes be quite difficult because they can move buttons around without sending an update."
"Qualys VM's vulnerability scan could be improved, especially the number of CVE numbers it can manage at a time."
 

Pricing and Cost Advice

Information not available
"The solution is expensive."
"The price is very reasonable."
"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."
"It's very expensive, especially if you want to use multiple modules of Qualys."
"Qualys Virtual Scanner Appliance isn't expensive right now. But the price for their product bundles could be better."
"The solution is reasonably priced for the value it provides."
"They have recently changed the pricing model, which is now better than it was before."
"In Nigerian Naira, we spend about roughly four to five million to use this solution and this is expensive compared to solutions like Nessus."
