We're gathering vulnerability data from multiple environments in real time, fundamentally changing how we identify issues in applications

The solution is very accurate in identifying vulnerabilities. In cases where we are performing application assessment using Contrast Assess, and also using legacy application security testing tools, Contrast successfully identifies the same vulnerabilities that the other tools have identified but it also identifies significantly more. In addition, it has visibility into application components that other testing methodologies are unaware of. Assess also provides the option of helping developers incorporate security elements while they're writing code. It depends on whether individual developers decide to utilize the information that's provided to them from the solution, but it definitely gives them visibility into more environments. It gives them an opportunity to remediate vulnerabilities well before production deployments.

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

Pros

"The solution is very accurate in identifying vulnerabilities. In cases where we are performing application assessment using Contrast Assess, and also using legacy application security testing tools, Contrast successfully identifies the same vulnerabilities that the other tools have identified but it also identifies significantly more. In addition, it has visibility into application components that other testing methodologies are unaware of."

"By far, the thing that was able to provide value was the immediate response while testing ahead of release, in real-time."

"The most valuable feature is the continuous monitoring aspect: the fact that we don't have to wait for scans to complete for the tool to identify vulnerabilities. They're automatically identified through developers' business-as-usual processes."

"I am impressed with the product's identification of alerts and vulnerabilities."

"Assess has an excellent API interface to pull APIs."

"We use the Contrast OSS feature that allows us to look at third-party, open-source software libraries, because it has a cool interface where you can look at all the different libraries. It has some really cool additional features where it gives us how many instances in which something has been used... It tells us it has been used 10 times out of 20 workloads, for example. Then we know for sure that OSS is being used."

"When we access the application, it continuously monitors and detects vulnerabilities."

"This has changed the way that developers are looking at usage of third-party libraries, upfront. It's changing our model of development and our culture of development to ensure that there is more thought being put into the usage of third-party libraries."

More Contrast Security Assess pros

"Licensing is the most valuable. Qualys provides the best licensing for companies. It is the best product for the development purposes of web applications. The product has a lot of integrations."

"It combines both web application vulnerability management and internal vulnerability management on one platform and dashboard. Usually, you have to purchase separate tools."

"By using QualysGuard, we are able to finish external scans with assured results in half the time."

"The advantage of Qualys Web Application Scanning lies in its user-friendly dashboard and appealing reports, which are useful for presentation to leadership."

"With our vulnerabilities under control, it's putting our services in compliance and minimizing our risk for exposure."

"It scans web applications to identify vulnerabilities during deployment."

"Key features include: Cloud-based, so the installation is not so tedious. Easily deployed. Highly scalable. Comprehensive reporting."

"The interface is user-friendly and easy to understand."

Cons

"The solution needs to improve flexibility...The scalability of the product is a problem in the solution, especially from a commercial perspective."

"I think there was activity underway to support the centralized configuration control. There are ways to do it, but I think they were productizing more of that."

"To instrument an agent, it has to be running on a type of application technology that the agent recognizes and understands. It's excellent when it works. If we're using an application that is using an unsupported technology, then we can't instrument it at all. We do use PHP and Contrast presently doesn't support that, although it's on their roadmap. My primary hurdle is that it doesn't support all of the technologies that we use."

"Contrast Security Assess covers a wide range of applications like .NET Framework, Java, PSP, Node.js, etc. But there are some like Ubuntu and the .NET Core which are not covered. They have it in their roadmap to have these agents. If they have that, we will have complete coverage."

"I would like to see them come up with more scanning rules."

"The product's retesting part needs improvement. The tool also needs improvement in the suggestions provided for fixing vulnerabilities. It relies more on documentation rather than on quick fixes."

"The setup of the solution is different for each application. That's the one thing that has been a challenge for us. The deployment itself is simple, but it's tough to automate because each application is different, so each installation process for Contrast is different."

"The solution should provide more details in the section where it shows that third-party libraries have CVEs or some vulnerabilities."

More Contrast Security Assess cons

"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 area of false positives could be improved. There are quite a number of false positives as compared to other solutions. They could probably fine tune the algorithm to be able to reduce the number of false positives being detected."

"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 solution needs to adjust its pricing. They should make it more affordable."

"The product's pricing could be better."

"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."

"It should have better automatic reporting."

"The downside of Qualys Web Application Scanning is that it cannot crawl automatically."

Pricing and Cost Advice

"The good news is that the agent itself comes in two different forms: the unlicensed form and the licensed form. Unlicensed gives use of that software composition analysis for free. Thereafter, if you apply a license to that same agent, that's when the instrumentation takes hold. So one of my suggestions is to do what we're doing: Deploy the agent to as many applications as possible, with just the SCA feature turned on with no license applied, and then you can be more choosy and pick which teams will get the license applied."

"It's a tiered licensing model. The more you buy, as you cross certain quantity thresholds, the pricing changes. If you have a smaller environment, your licensing costs are going to be different than a larger environment... The licensing is primarily per application. An application can be as many agents as you need. If you've got 10 development servers and 20 production servers and 50 QA servers, all of those agents can be reporting as a single application that utilizes one license."

"You only get one license for an application. Ours are very big, monolithic applications with millions of lines of code. We were able to apply one license to one monolithic application, which is great. We are happy with the licensing. Pricing-wise, they are industry-standard, which is fine."

"I like the per-application licensing model... We just license the app and we look at different vulnerabilities on that app and we remediate within the app. It's simpler."

"The solution is expensive."

"For what it offers, it's a very reasonable cost. The way that it is priced is extremely straightforward. It works on the number of applications that you use, and you license a server. It is something that is extremely fair, because it doesn't take into consideration the number of requests, etc. It is only priced based on the number of onboarded applications. It suits our model as well, because we have huge traffic. Our number of applications is not that large, so the pricing works great for us."

"The product's pricing is low. I would rate it a two out of ten."

"Qualys Web Application Scanning's pricing is a bit expensive compared to other solutions available in the market."

"We are on an annual license for the solution and the pricing could be more affordable."

"The product has a very good licensing model."

"There are different options available with respect to licensing."

"We normally purchase an annual license."

"Pricing was reasonable and competitive. It was not too far above the other products."

"Qualys WAS' pricing is competitive."

"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."
