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.

Centralized license management transforms asset manipulation based on functions and improves security posture

Now that the license is centralized, it's a significant feature to manipulate assets based on their functions. It provides a centralized view from end-to-end to its assets' identities and vulnerabilities. One of the greatest features is Kubernetes. The automated scanning capability is pretty standard in the market, and Tenable's prioritization engine helps improve the security posture.

Cons

"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."

"In certain cases, this product does have false positives, which the company should work on."

"I have dealt with Qualys's technical support, and any enhancements are challenging. I would rate them a five out of ten."

"In terms of the Policy Compliance model which they currently have, not all the platforms are being covered. If they could improve on the Policy Compliance model, since there are policies which are benchmarked against it, this will be helpful for us."

"The reporting contains too many false positives."

"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."

"Qualys Web Application Scanning is very complex to use, and its graphical interface is not very user-friendly."

"The pricing does not seem to be competitive."

More Qualys Web Application Scanning cons

"They have a general dashboard for web application scanning, but the dashboards and reporting can be improved. They probably have some features in their roadmap."

"The market is standard for vulnerability scanning, however, the posture can be improved through Tenable's prioritization engine."

"The technical support needs improvement. Currently, it takes time, which might be due to the free version, but providing some level of support could encourage future purchase decisions."

"It would be great if there were a dashboard that is more user-friendly."

"The report customization needs to be better."

"The platform's technical support services could be better."

"Sometimes it lags with different cloud environments."

"We have encountered some problems with the technical support from Tenable; I would rate it a five out of ten. It is not efficacious, especially the first-level support."

More Tenable.io Web Application Scanning cons

Pricing and Cost Advice

"We normally purchase an annual license."

"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."

"It is an expensive platform."

"Licensing was based on the number of assets that you want to scan on your network. You can also do licensing on subscription. On subscription, it is easier and more flexible. You tell Qualys that you want to move from the 1000 to 2000 band or the 3000 or 5000 band, then they will give you the quotation for it. Once you pay for it, applying the licensing is quite easy and effective."

"Qualys WAS' pricing is competitive."

"I rate the software’s pricing a six out of ten."

"From my perspective, it is a budget-friendly option."

"The product has a very good licensing model."

More Qualys Web Application Scanning pricing and cost advice

"It follows the same licensing scheme as Tenable.io and Tenable. sc."

"The price of the solution is reasonable compared to the competitors. The license cost is based on the number of users and the annual usage."

"The application is extremely affordable. There are no additional costs involved with licensing. We switched to Tenable.io Web Application Scanning from other solutions due to pricing."

"Tenable.io Web Application Scanning is expensive for small businesses."

"I rate the product's pricing a four out of ten."

"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."

"The pricing is okay."
