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.

Improved radiation safety and compliance has supported patient care but daily workflows still need refinement
I think it can be improved by making it more practical, integrated, and easier for teams to apply in real-world workflow from a healthcare perspective. The main improvements I can see right now are better user training with real-case scenarios rather than only theory, and clear and simple protocols for day-to-day operations. Strong integration between safety compliance and documentation systems would help significantly in practice for the healthcare field, which is a niche field. The biggest gain would come from making security processes easier to follow consistently, especially in busy environments where teams need to be aware of clarity and really need to rely on the documentation they are using.I chose a rating of seven because it offers strong value in safety, risk reduction, and compliance, especially in healthcare. However, there is still room for improvement in usability and day-to-day integration. Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow.

Streamlines prioritization but reporting needs enhancement
There are several areas needing improvement. The product helps, but the reporting relies heavily on Power BI. It is limited to graphical views and requires additional filtering, posing operational challenges. The inability to download specific asset details directly from the Power BI portal is a drawback, particularly for non-technical users, though it provides high-level executive summaries. The reporting model should be enhanced so that we have the flexibility to download. We have requested a few features, and they are open to accepting those requests. It needs ITSM improvements. It has out-of-the-box integration with ServiceNow, but the customer is using BMC Helix ITSM. We would like an integration with BMC Helix ITSM. When uploading CSV files without an out-of-the-box connector, duplicate entries for assets occur. We have already reported this to them, but we are not sure when they will fix it. It will significantly benefit if we can directly upload business context information from CMDB without manual merging efforts. It can also have automatic remediation capabilities through SCCM or something else.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"CSPM is currently the most used feature, and we are enjoying the new feature, FlexScan, which is valuable for Internet-facing VMs."
"Vulnerability and threat detection and assessment of the criticality of the vulnerabilities exposed are most valuable."
"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other platforms."
"The most valuable feature of Qualys TotalCloud is the visibility it provides."
"I would definitely recommend Qualys TotalCloud to other customers."
"Qualys TotalCloud's most valuable features are its security capabilities that help identify and mitigate risk factors."
"One of the features I appreciate is the ability to generate daily reports without relying on anyone else."
"In my opinion, this is the best tool."
"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."
"It has allowed us to bring together multiple sources of information from different signal sources into a single point."
"Vulcan Cyber has helped reduce our organization’s mean time to remediation."
"The most notable aspects include having prioritization capabilities and custom scripts."
"Out of the three solutions I've used, Vulcan Cyber is the superior option."
"I was part of the initial deployment. It was pretty easy. To fully deploy, it took about three or four weeks."
"Vulcan Cyber gives the remediation team the focus points."
"I find the ability to consolidate information from multiple vulnerability scanners into a single source valuable."
"It is very good when it comes to ingesting information from different sources and then displaying this information in an easy-to-use platform."
 

Cons

"Qualys's ticketing system can be confusing when assigning tasks to individuals, and support could be improved by offering instant call solutions with engineers in addition to ticket replies."
"To improve the user experience, reporting could be simplified for better comprehension by end users and project managers, facilitating issue resolution."
"With the growing integration of AI, I would like Qualys to enhance its service offerings to better accommodate AI-related risks."
"The response part of the Cloud Detection and Response (CDR) module can be improved."
"The onboarding process is a bit difficult. In the initial phase, it is very difficult to understand the features, what the dashboard contains, and what criteria they are using."
"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."
"Although TotalCloud is a helpful tool, some of its advanced features are still under development."
"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."
"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."
"Improvements are needed in providing more concise details on how to apply remedies for particular vulnerabilities."
"Initially, when onboarding Vulcan Cyber, the setup and configuration was more complex than expected with a user-friendly approach. This aspect can be enhanced."
"Monitoring of the evolution of campaigns and perhaps having more customized options for monitoring them would be great."
"Their support is good, but there are some flaws as well. We often encounter some issues that are not applicable to Vulcan Cyber as a whole; they apply only to us because we have customized requirements. In such cases, when we reach out with specific data and issues to their support team, they sometimes come back and say that the issues have been resolved. However, when we test to see if they have been remediated, they are still there."
"It would be extremely helpful to have a community group around the product."
"There are several areas needing improvement. The product helps, but the reporting relies heavily on Power BI. It is limited to graphical views and requires additional filtering, posing operational challenges."
"The fact that we cannot use it for our reporting leads me to rate it three out of ten."
"We wish we had more insights into how they weigh the risks associated with the threat intel."
 

Pricing and Cost Advice

"Qualys TotalCloud offers cost-effective licensing flexibility."
"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"TotalCloud's price is about right where I would expect it to be."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."

Information not available
"Its pricing is quite fair compared to what is out there in the market, especially compared to the tool from Microsoft. It is a SaaS platform that has an annual cost, so it is something that is already used by many companies. It is quite affordable."
"Our leadership knows better about the pricing. As per my knowledge, which might not be accurate, its price can come down."
