It provides us with more in-depth visibility into ongoing attacks.
I rate Contrast Security Protect eight out of 10. Overall, it's a solid product, but I deduct a couple of points because of the interface and some shortcomings in the reporting. If you have a large enterprise where you're dealing with a lot of servers, then it makes sense not to use the internal MySQL database. You should use something like Oracle or Microsoft SQL, but if you don't have many transactions, the embedded MySQL database works great.

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

"The product gives a few false positives. We get 99 percent true positives."
"The Protect solution allows applications to continue to run, even with known vulnerabilities, but will report or block attempts to exploit the vulnerabilities."
"Protect provides us with more in-depth visibility into ongoing attacks."
"Contrast Security's support is great. They're willing to spend a lot of time on your problem."
"The solution has excellent real-time capabilities."
"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

"We're not using it much anymore because we had some performance issues."
"There's room for improvement in the initial setup."
"There's room for improvement in the initial setup."
"Protect's reporting GUI is very basic. To get all statuses from the APIs, we needed to write our own KPI dashboard to provide reports."
"Contrast Security Protect needs to improve integration."
"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."
"I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities."
