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.

Centralized security testing has improved vulnerability remediation and compliance reporting
I recommend more enhancements focusing on penetration testing for both SSL over HTTP and non-SSL over HTTP, specifically targeting the RCP Rich Client Platform and Equinox frameworks that allow on-premises desktop applications to be tested simultaneously. I believe those would significantly improve the tool in the future. I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities. Once we build this installer—rather than just working on the codebase—sometimes, we face gaps considering the build parameters and conversions to the installer. Identifying those gaps is an area that could use improvement after the installer or desktop application testing, which would be beneficial. That is the only reason; otherwise, I could easily rate it a ten out of ten given its smooth operational process.

Quotes from Members

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

Pros

"I am impressed with the product's identification of alerts and vulnerabilities."
"Overall, the product is strong and improving, support is responsive and effective, and supported integrations work for many customers."
"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."
"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."
"From a percentage perspective, somewhere around 90 percent of the time we used to spend has been given back to our team, because the false positive rate with Contrast is less than 5 percent."
"The time it saves us is on the order of one US-based FTE, a security person at an average pay level, and at a bare minimum Contrast helps us like that resource; it's like having a CISSP guy, in the US, on our payroll."
"One of the key takeaways is that in order to have a secure application, you cannot rely on just the pentest, vulnerability assessments, and the periodicity of the reviews; you need the real-time feedback on that, and Contrast Assess offers that."
"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."
"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."
"I think the best features that Nucleus Security offers are purely the faster remediation to dev tools, which is crucial for managing, prioritizing, and fixing vulnerabilities while helping operational pipelines run these vulnerability management tools."
 

Cons

"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."
"Personalization of the board and how to make it appealing to an organization is something that could be done on their end."
"The out-of-the-box reporting could be improved. We need to write our own APIs to make the reporting more robust."
"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."
"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."
"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."
"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."
"I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities."
"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."
 

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."
"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."
"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."
"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."
