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.

Test assurance improves compliance and products with good performance

The user interface could be improved to facilitate easier navigation. The most significant issue I encounter with the solution is the user interface. It would be beneficial if I could remain on one screen most of the time. Even if the system navigates me to another screen, it should effectively return me to the main screen.

Quotes from Members

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

Pros

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

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

"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."

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

"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."

"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."

"No other tool does the runtime scanning like Contrast does. Other static analysis tools do static scanning, but Contrast is runtime analysis, when the routes are exercised. That's when the scan happens. This is a tool that has a very unique capability compared to other tools. That's what I like most about Contrast, that it's runtime."

More Contrast Security Assess pros

"Our customers use it to check for unauthorized file transfer."

"The testing compliance feature is particularly impressive."

"CyberFlood's best features are its user-friendliness and scheduling function."

"CyberFlood is flexible."

"The testing compliance feature is particularly impressive."

"The feature I find most valuable is the traffic generator."

Cons

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

"Regarding the solution's OSS feature, the one drawback that we do have is that it does not have client-side support. We'll be missing identification of libraries like jQuery or JavaScript, and such, that are client-side."

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

"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."

"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 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."

"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."

"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."

More Contrast Security Assess cons

"The initial setup is not straightforward and can be quite challenging."

"The user interface could be improved to facilitate easier navigation."

"The solution needs more ports, more speed, and more gigabytes."

"CyberFlood's accessibility and support for multiple browsers could be better."

"I would also like to see updates on a more frequent schedule."

"Sometimes, when you configure parameters the hardware can't run, it will get stuck at those points without telling you what happened. It would be helpful if the error reporting provided more details about why the test setting is not running. It would be nice if there were a space in the hardware module for you to add some external hardware for more rigorous testing."

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."

"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."

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

"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'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."

"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."

"CyberFlood is reasonably priced."
