Though a stable tool, the UI needs improvement
Kiuwan can improve its UI a little more. The user experience can be made better. Kiuwan offers a user interface that is similar to the one offered by Windows 7 or Windows 98, which I saw when I ran the tool and tried to scan the repository to find the security issues. The product's UI has certain shortcomings, where improvements are required.

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

"We have been using this solution for one and a half years."
"The solution offers very good technical support."
"Saving time and money by automatically identifying problems is unbelievable."
"We have had an improvement of 20% in our time to market and it significantly improved the quality of our code."
"I personally like the way it breaks down security vulnerabilities with LoC at first glance."
"I like that it provides a detailed report that lets you know the risk index and the vulnerability."
"The technical support is very good, and we have received valid answers to our questions."
"The solution has a continuous integration process."
"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."
"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."
 

Cons

"The QA developer and security could be improved."
"We faced a lot of problems with the initial setup and support gave us difficulties around the installation."
"The next release should include more flexibility in the reporting."
"The development-to-delivery phase."
"The integration process could be improved. It'll also help if it could generate reports automatically, but I'm not sure about the effectiveness of the reports because in our last project, we still found some key issues that weren't captured by the Kiuwan report."
"For mobile development, we are not too experienced, and it is not the perfect tool because the integration with certain products is very manual."
"Different languages, such Spanish, Portuguese, and so on."
"The pricing and licensing models are poor."
"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

"I recommend contacting a sales person who will create the best plan payment plan for you, as we did."
"This solution is cheaper than other tools."
"Nothing special. It's a very fair model."
"Check with your account manager."
"Kiuwan is an open-source solution and free to use."
"The price of Kiuwan is lower than that of other tools on the market."
"It follows a subscription model. I think the price is somewhere in the middle."
