Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

Unified vulnerability workflows have transformed how our teams prioritize and resolve critical risks
While the platform is incredibly powerful, the initial configuration curve of Nucleus Security can be a bit steep. When first setting up complex, multi-layered automation rules and asset groupings, the interface can feel a little overwhelming. Having more intuitive step-by-step visualized wizards or guided templates for building complex triage workflows would make the onboarding process much smoother for new team members. Dashboard customization and reporting would definitely be on my wish list. While the default dashboards are great for a general overview, it can take a bit of manual tweaking when building highly tailored workspace views for different engineering groups. Having a more flexible drag-and-drop widget system where individual teams can prioritize exactly what metrics they see first on their layout would be a huge quality of life update. On the reporting side, the data it generates is solid, but I would like to see more granular control over formatting within the platform itself. Sometimes leadership wants data tailored in very specific ways, and currently, we occasionally have to export the data and clean it up externally to meet those exact visual preferences.

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

"If someone were to ask me to review Qualys TotalCloud, I would summarize it as an end-to-end solution for cloud security with visibility and governance-grade controls without needing to manage multiple disconnected tools."
"Qualys TotalCloud's most valuable feature is its agent versatility."
"Qualys TotalCloud fulfills all these needs."
"Qualys TotalCloud provides a single, prioritized view based on requirements such as identifying the most vulnerable assets and calculating the average time to remediate vulnerabilities."
"I appreciate Qualys TotalCloud's ability to onboard any type of device with ease, including containers."
"Qualys TotalCloud is an excellent platform, and the beauty of the platform is that we can get all the vulnerabilities, see all the reports in a single dashboard, view them segregated, and easily learn about critical, high, and medium findings with appropriately provided remediation steps."
"Qualys TotalCloud provides unified vulnerability and threat assessment for IaaS and SaaS and a single prioritized view of risk, which helps reduce my workload by not having to combine multiple sources."
"In my opinion, this is the best tool."
"Nucleus Security has fundamentally changed how we manage our vulnerability lifecycle and made our entire incident response process much more proactive, organized, and reliable."
"The best features that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms."
"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."
"What I like about Qualys VM is the dashboard presentation. It's very good."
"I like Qualys because it is a very complete product, more so than Tenable."
"There are fewer false positives when using this solution, and we are also cutting the need for news monitoring with this solution."
"The Qualys Agent is most valuable for getting insight into what is happening on what device with all its metadata."
"Qualys VMDR provides a real-time response and reporting feature, which is excellent."
"The solution, overall, is very useful for our organization; it is very easy to use and there are lots of options, and we can usually easily go through it and all of the things we want to configure, and we can configure everything to our specifications very easily."
"It gives a very good overview of the inventory assessment process, and it can be accessed across our company because it's a global tool."
 

Cons

"With the growing integration of AI, I would like Qualys to enhance its service offerings to better accommodate AI-related risks."
"Qualys TotalCloud needs to enhance its scanning capabilities in the IP domain, as it currently lacks the functionality to resolve IPs to their corresponding domain names."
"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."
"I think Qualys TotalCloud needs to improve its handling of zero-day vulnerabilities and supply chain management because modern ransomware attacks not only target prime critical infrastructures but also the supply chain system."
"There is a lack of data segregation according to criticality or inventory."
"Overall, we are satisfied with it. However, the response part of the Cloud Detection and Response (CDR) module can be improved. It is not yet in place according to requirements; it is not completely available even though the module has been released."
"Although TotalCloud is a helpful tool, some of its advanced features are still under development."
"Regarding technical support from Qualys, they respond, but the response time can be too long. Sometimes we need to wait weeks for solutions to simple questions."
"While the platform is incredibly powerful, the initial configuration curve of Nucleus Security can be a bit steep."
"Nucleus Security needs a better view into exposure management, as exposure management and attack path management are missing."
"Support could be a little bit faster."
"The reporting section needs improvement as running reports can take several hours."
"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."
"The disadvantage of working with Qualys is that the graphical interface is quite outdated."
"Qualys VM's scanner doesn't pick up every vulnerability, so we have to use multiple scanners to cover that gap."
"There needs to be better documentation."
"I do not like that all of the data is stored on the cloud."
"There are scenarios where a vulnerability is reported once yet not in subsequent scans, even if we have not fixed it."
 

Pricing and Cost Advice

"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
