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.

Unified vulnerability view has improved risk-based decisions but reporting still needs work
One of the main issues with Nucleus Security is its lack of reporting capability. The user interface resembles an early 2000s application style, and although its speed is decent, it could be improved as more data is ingested. The overall appearance and feel need work, especially compared to modern applications from Rapid7, Qualys, and Tenable, which have more engaging user interfaces. The reporting capability is severely lacking; not being able to filter to granularity or have custom built queries is an annoyance that needs an overhaul. Additionally, there are bugs that have not been resolved, such as when you create a report and remove an asset, the asset still appears in the report despite not being present in the system anymore, leading to issues that need to be addressed quickly. Nucleus Security can become a difficult investment because I already have a vulnerability management solution, and I question where Nucleus Security fits with its licensing model. While I acknowledge automation has been described, it would be amazing to control the entire vulnerability management workflow from Nucleus Security without needing to log onto other systems. Having controls or actions that can be sent from the console down to the scanner for rescans would be beneficial. If Nucleus Security is going down this path, it should ensure that it becomes a one-stop shop for vulnerability management across multiple applications.

Quotes from Members

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

Pros

"We switched because Kiuwan covers the entire SDLC; provides direct information to act upon, for the developer, architects, QA, CIO and CISO, in a few seconds; automatically, fully integrated in any CI/CD setup."
"I like that it provides a detailed report that lets you know the risk index and the vulnerability."
"Lifecycle features, because they permit us to show non-technical people the risk and costs hidden into the code due to bad programming practices."
"The feature that I have found the most valuable in Kiuwan is the speed of scanning. Compared to other SaaS tools I have used, Kiuwan is much quicker in performing scans. I have not yet used it on a large code base, but from what I have experienced, it is efficient and accurate. Additionally, I have used it both manually and in an automated pipeline, and both methods have been effective. The speed of scanning is what makes it valuable to me."
"I like that I can scan the code without sending it to the Kiuwan cloud. I can do it locally on my device. When the local analyzer finishes, the results display on the dashboard in the cloud. It's essential for security purposes to be able to scan my code locally."
"We are using this solution to increase the quality of our software and to test the vulnerabilities in our tools before the customers find them."
"I advise using Kiuwan because it's very straightforward and totally easy to understand."
"I find it immensely helpful because it's not just about generating code; it's about ensuring efficiency in the execution."
"Nucleus Security has impacted my organization positively by providing a single pane view of vulnerabilities from different connectors and enabling the automation of reporting and alerting on findings that are out of due date or out of SLA."
"The best features Nucleus Security offers, in my opinion, are that it is really great in showcasing things and providing centralized vulnerability management."
"Nucleus Security has fundamentally changed how we manage our vulnerability lifecycle and made our entire incident response process much more proactive, organized, and reliable."
"The best features that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms."
 

Cons

"I would like to see better integration with Azure DevOps in the next release of this solution."
"The solution seems to give us a lot of false positives. This could be improved quite a bit."
"Improvement could be made with the integration of the programming tools."
"More languages and frameworks would enhance this tool."
"The development-to-delivery phase."
"It could improve its scalability abilities."
"The QA developer and security could be improved."
"The pricing and licensing models are poor."
"On a scale of one to ten, I would rate Nucleus Security overall a six."
"Nucleus Security needs a better view into exposure management, as exposure management and attack path management are missing."
"One of the main issues with Nucleus Security is its lack of reporting capability."
"While the platform is incredibly powerful, the initial configuration curve of Nucleus Security can be a bit steep."
 

Pricing and Cost Advice

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