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 data has transformed risk prioritization and optimized remediation effort
The best features that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms. It is helping quite a lot to unify all of that. It also offers good prioritization based on the EPSS or the CVSS score, as well as different other factors including Mandiant threat intelligence and similar aspects. It helps bring it all into one big picture instead of different silos of vulnerabilities. The integrations make my job easier because I can connect my other tools, which is the most important part of this tool to bring in all the vulnerabilities from the different other tools. The prioritization changed it from chasing vulnerabilities or pushing colleagues to patch vulnerabilities to providing colleagues with their vulnerabilities and requesting remediation and patching. Nucleus Security positively impacts my organization by bringing awareness to vulnerability management since we can actually determine how many vulnerabilities we have and how critical the risk is, or we can quantify the risk overall for the company.

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:

"The platform's unified view of the organization proves particularly valuable for leadership team meetings."

"In my opinion, this is the best tool."
"TruRisk Insights is the most important innovation they've released this year."

"I find the most valuable features are the continuous monitoring. Even on premises, there is constant monitoring."
"It gives you a lot of options, and it integrates with our ServiceNow for ticketing and all."
"I am impressed with the VMDR feature."
"The advantage with Qualys is that you get a lot of features because it has been a market leader for quite a long time."
"Great web application security for scanning."
"In a world of the hybrid workforce and work from home, if you're looking for a more effective vulnerability management tool, you have to go to the agent-based vulnerability management tools that are out there, and we've been extremely happy with Qualys."
"What I like about Qualys VM is the dashboard presentation. It's very good."
 

Cons

"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"The downside is only in container security, but it has not been a long time since they introduced these models."
"Their customer support needs improvement."
"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."
"It has been working very well, but it would be helpful if the dashboard could generate reports tailored to specific compliance needs. For example, in India, we have to comply with RBI and SEBI guidelines. It w"
"The cost of Qualys TotalCloud is high and could be more competitive."
"Their support could be improved."
"Nucleus Security needs a better view into exposure management, as exposure management and attack path management are missing."
"Web application security model needs some work."
"For a beginning, the initial setup is complex. You have to have some knowledge for setting it up and using it."
"They should make it accessible for more operating systems."
"It's too early for me to say if there is any room for improvement since we're in the first couple of months of using this solution."
"One of the biggest issues from the clients' perspective is that all Qualys computing is on the cloud."
"Certain integration factors between different options could be improved."
"Its integration with ServiceNow and other similar products is complicated and can be improved."
"Qualys VMDR should improve authenticated scanning capabilities."

Information not available
"The product is more expensive than that of any other vendor."
"Qualys VM is reasonably priced."
"Qualys VM is better suited for medium to large companies because the price can be too much for smaller customers."
"The tool's pricing is expensive and I would rate the pricing a seven out of ten."
"The price is very reasonable."
"I used to work there, so I never paid for the product. As an employee, we get a lifetime license for personal use, and that's what I'm using. It is a comprehensive platform, so there is a lot more to it. There could be other solutions that are probably a little bit cheaper, but it depends on what people need. Different people have different needs. It offers many things on the same platform. If you add all the things up, it should be cheaper, but I have not done any analysis specifically."
"The pricing and licensing for Qualys could be improved."
"The solution is reasonably priced for the value it provides."
