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.

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 most valuable feature is that it analyzes data in real-time."
"Fortify Application Defender's most valuable features are machine learning algorithms, real-time remediation, and automatic vulnerability notifications."
"The solution helped us to improve the code quality of our organization."
"The information from Fortify Application Defender on how to fix and solve issues is very good compared to other solutions."
"The most valuable feature is the ability to automatically feed it rules what it's coupled with the WebInspect dynamic application scanning technology."
"Its ability to find security defects is valuable."
"Its ability to find security defects is valuable."
"The most valuable features of Fortify Application Defender are the code packages that are default."
"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 workbench is a little bit complex when you first start using it."
"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."
"Support for older compilers/IDEs is lacking."
"Fortify Application Defender could improve by supporting more code languages, such as GRAAS and Groovy."
"The false positive rate should be lower."
"The solution could improve the time it takes to scan. When comparing it to SonarQube it does it in minutes while in Fortify Application Defender it can take hours."
"The solution is quite expensive."
"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."
"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."
 

Pricing and Cost Advice

"Fortify Application Defender is very expensive."
"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 product’s price is much higher than other tools."
"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."
"The base licensing costs for the SaaS platform is about $900 USD per application, per year."
