CTO at Abcl
Useful for fast code review in devOps pipelines
I rate the tool's scalability a seven out of ten. However, I'm concerned about how it handles an increasing number of lines of code. As the complexity grows, so does the time it takes for the tool to review everything. I want more clarity on how Fortify Application Defender handles multiple threats. We have numerous endpoints, but the tool runs in our pipeline, meaning it operates in the cloud. All our code is configured there, and the tool runs integration testing, unit testing, user testing, and final production code tests. It's a day-to-day experience. It's utilized almost every day as part of our pipeline runs. Each team responsible for integration testing, human testing, user access testing, and preproduction testing runs it whenever they take a build.

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.

Pros

"I find the configuration of rules in Fortify Application Defender useful. Its integration is also easy."
"It is one of those things that once you see it in action, it is pretty impressive."
"The solution helped us to improve the code quality of our organization."
"Fortify Application Defender's most valuable features are machine learning algorithms, real-time remediation, and automatic vulnerability notifications."
"We are able to provide out customers with a secure application after development. They are no longer left wondering if they are vulnerable to different threats within the market following deployment."
"This is a great tool and the kind of support it provides is very helpful."
"The most valuable feature is the ability to automatically feed it rules what it's coupled with the WebInspect dynamic application scanning technology."
"The product saves us cost and time."
"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 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 that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms."
"Nucleus Security has fundamentally changed how we manage our vulnerability lifecycle and made our entire incident response process much more proactive, organized, and reliable."
 

Cons

"The false positive rate should be lower."
"Fortify Application Defender could improve by supporting more code languages, such as GRAAS and Groovy."
"The licensing can be a little complex."
"The workbench is a little bit complex when you first start using it."
"Fortify Application Defender gives a lot of false positives."
"The biggest complaint that I have heard concerns additional platform support because right now, it only supports applications that are written in .NET and Java."
"Support for older compilers/IDEs is lacking."
"The product should integrate industry-standard code review tools internally with its system. This would streamline the coding process, as developers wouldn't need multiple tools for code review and security checks. Many independent and open-source tools are available, from Apache to various libraries. Using multiple DevOps pipeline tools can slow the turnaround time."
"While the platform is incredibly powerful, the initial configuration curve of Nucleus Security can be a bit steep."
"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."
 

Pricing and Cost Advice

"The product’s price is much higher than other tools."
"I rate the solution's pricing a five out of ten. It comes as an annual cloud subscription. The tool's pricing is around 50 lakhs."
"The price of this solution could be less expensive."
"The base licensing costs for the SaaS platform is about $900 USD per application, per year."
"Fortify Application Defender is very expensive."
"The licensing is very complex, it's project based and can range from $10,000 to $200,000+ depending on the project type and size."
