Health Care Specialist at a healthcare company with 11-50 employees
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.

Web scanning needs improvement but offers good vulnerability detection
The downside of Qualys Web Application Scanning is that it cannot crawl automatically. If I provide an IP address and a login form, it does basic testing, but it doesn't go deep as IBM AppScan does. If Qualys Web Application Scanning could improve its crawling capability, it would be more user-friendly. Qualys Web Application Scanning does IP-level testing, requiring direct input of credentials, and can only scan a few pages to provide known generic vulnerabilities, which isn't as beneficial from my point of view. The Vulnerability Management also relies heavily on version numbers and will flag vulnerabilities based on the component version, but it doesn't check if a real fix exists, leading to flags on components that actually have workarounds available.

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."
"Qualys Web Application Scanning is very stable and reliable."
"Network scanner has good reporting, coverage was also good."
"Qualys' process of updating signatures is something we really appreciate, and it's way ahead of its industry peers."
"The simplicity of exporting reports and the simplicity and clarity of the reports included with the product are good."
"The features of Qualys Web Application Scanning are impressive as the scan is faster and gets completed quickly, the dashboards look great, the option for scheduled scans makes it fully automated, and customizable reports can be downloaded anytime in CSV, PDF, or whichever format required."
"By using QualysGuard, we are able to finish external scans with assured results in half the time.​"
"It is a cloud-based solution, so it is easy to scale."
"It combines both web application vulnerability management and internal vulnerability management on one platform and dashboard. Usually, you have to purchase separate tools."
 

Cons

"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."
"The reporting contains too many false positives."
"The virus code updates are not frequent enough."
"The support could be faster."
"Qualys Web Application Scanning is very complex to use, and its graphical interface is not very user-friendly."
"We receive false positives sometimes when using a solution that could be improved. However, the technical team provides us with the exact explanation why it was giving us that kind of error."
"The downside of Qualys Web Application Scanning is that it cannot crawl automatically. If I provide an IP address and a login form, it does basic testing, but it doesn't go deep as IBM AppScan does."
"The organization of the assets was a little confusing and overwhelming."
"The GUI could be a little less complicated as it opens a lot of new windows for creating search lists, templates, reports, or for scanning purposes."
 

Pricing and Cost Advice

Information not available
"Try the free trial of the product to understand the basic working mechanisms.​"
"Qualys has an IT-based licensing based on a yearly license, which is a good way of handling it. However, in some cases, when we do the PCI scanning, the host will not like the scanning and we lose the IT license. So, this could be improved."
"The product pricing is fair and reasonably priced."
"Qualys WAS' pricing is competitive."
"​It is best to be an institutional buyer and directly contact the sales team, as they can provide over-the-top discounts for bulk orders​."
"The product has a very good licensing model."
"It is an expensive platform."
"From my perspective, it is a budget-friendly option."
