It has an excellent API interface to pull APIs.
Assess has brought our development time down because it helps create code the first time. Instead of going through the Jenkins process to build an application, they can see right off the bat that if there are errors in the code and fix them before it even goes to build.

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

"In our most critical applications, we have a deep dive in the code evaluation, which was something we usually did with periodic vulnerability assessments, code reviews, etc. Now, we have real time access to it. It's something that has greatly enhanced our code's quality. We have actually embedded a KPI in regards to the improvement of our code shell. For example, Contrast provides a baseline where libraries and the usability of the code are evaluated, and they produce a score. We always aim to improve that score. On a quarterly basis, we have added this to our KPIs."
"I am impressed with the product's identification of alerts and vulnerabilities."
"The accuracy of the solution in identifying vulnerabilities is better than any other product we've used, far and away."
"It is a stable solution...Contrast Security Assess is one of the first players in this market, so they have experience and customers, especially abroad. Overall, it's a good product."
"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."
"Contrast was a very complete solution; it met all of our technical requirements and it was really the only IAST product that felt like a real product."
"The accuracy of the solution in identifying vulnerabilities is better than any other product we've used, far and away. In our internal comparisons among different tools, Contrast consistently finds more impactful vulnerabilities, and also identifies vulnerabilities that are nearly guaranteed to be there, meaning that the chance of false positives is very low."
"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."
"​QualysGuard web-based scanner is very useful for performing external penetration and PCI scans from remote locations.​"
"Its most valuable features are patch management, vulnerability management, and PCI compliance."
"I have found the detection of vulnerabilities tool thorough with good results and the graphical display output to be wonderful and full of colors. It allows many types of outputs, such as bar and chart previews."
"It is a very stable solution."
"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."
"The most valuable feature is that we are able to scan the services and put credentials like a user ID password, and we can verify the vulnerability level."
"The most valuable feature is that we are able to scan the services and put credentials like a user ID password. We can verify the vulnerability level."
"The Qualys Web Application Scanning solution offers a single comprehensive console and consolidated reporting, covering all aspects from on-prem to cloud and compliance, etcetera."
 

Cons

"The solution needs to improve flexibility...The scalability of the product is a problem in the solution, especially from a commercial perspective."
"Contrast's ability to support upgrades on the actual agents that get deployed is limited. Our environment is pretty much entirely Java. There are no updates associated with that. You have to actually download a new version of the .jar file and push that out to your servers where your app is hosted. That can be quite cumbersome from a change-management perspective."
"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."
"Their level of support and troubleshooting for the product is limited because of how they handle troubleshooting. It's done through a log file that's very cumbersome to work with."
"Personalization of the board and how to make it appealing to an organization is something that could be done on their end. The reports could be adaptable to the customer's preferences."
"The solution should provide more details in the section where it shows that third-party libraries have CVEs or some vulnerabilities."
"My primary hurdle is that it doesn't support all of the technologies that we use."
"I would like to see them come up with more scanning rules."
"There should be better visibility into the application."
"The UI is not user-friendly and you don't have a yearly reporting facility where you can slice and dice in different jobs."
"I have experience with adaptive scanning for single-page applications, which was not very effective."
"It is unclear how to build automation on Qualys. We do some automation, but not fully, because working is difficult."
"It should have better automatic reporting."
"The tool should have a live HTTP editor and more configuration options for some situations, such as handling applications that have URL rewriting enabled."
"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 software’s pricing could be improved."
 

Pricing and Cost Advice

"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 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."
"The product's pricing is low. I would rate it a two out of ten."
"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."
"The solution is expensive."
"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."
"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."
"It is an expensive platform."
"The product has a very good licensing model."
"We are on an annual license for the solution and the pricing could be more affordable."
"The product pricing is fair and reasonably priced."
"The product is expensive, at least initially, in comparison to other products in this category."
"Try the free trial of the product to understand the basic working mechanisms.​"
"​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​."
"From my perspective, it is a budget-friendly option."
