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."
"It is a stable solution."
"The most valuable feature is the connection of threat intelligence information with identified vulnerabilities, which means you can prioritize vulnerabilities according to actual attacks."
"The prioritization mechanism is the most valuable aspect of the solution."
"Qualys VMDR provides us with a quick response to threat findings through regular scheduled scanning, which improves our security operations."
"The most valuable feature of Qualys Container Security is the detailed information in the reports and the remediation, which is done to make sure there are no vulnerabilities."
"Qualys VM's best feature is vulnerability management."
"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."
"The most valuable features of Qualys VMDR include patch management and the use of virtual scanners to scan appliances and devices, especially those provided by vendors where we cannot manage them ourselves."
 

Cons

"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."
"I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities."
"Support could be improved since the response can be slow."
"Sometimes the scanning can get overwhelmed and start to drag when a lot of users are trying to scan at once."
"When tested on Zero day, there were errors."
"The IoT scan is not great and we would like to see some improvements to it."
"It would be helpful to have features for better tracking, including options for adding relevant owners or supporting groups for each asset."
"The disadvantage of working with Qualys is that the graphical interface is quite outdated."
"I would like to have CSPM, a continuous scan-like cloud added to the solution."
"Ticket management"
