We maintain high code standards with effective static code analysis and integration
SonarQube Server (formerly SonarQube) could be improved on the reporting front. Instead of grouping, I would prefer to scan the code as part of development and then generate a report on a daily basis among different units or projects, which is currently complicated. We need to change it to more of a portfolio report, where configuring or setting up things on the portfolio requires tagging at the ADO level.

Quotes from Members

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

Pros

"It is a good deal compared to all other tools on the market."
"With SonarQube's web interface, it is easy to drill down to see the individual problems, but also to look at the project from above and get the big picture, with possible larger problem areas."
"The SonarQube dashboard looks great."
"Provides local scanning for developers."
"Engineers now feel much more proud of their solution as they gain confidence from these scans and their results."
"The product has a friendly UI that is easy to use and understand."
"We have seen a decrease of about 25% of issues from since we first started using it a few months ago, and my team code bases are getting better."
"Engineers have also learned from the results and have improved themselves as engineers. This will help them with their careers."
More SonarQube pros
"The most valuable features of Synopsys API Security Testing are the metrics, results, and threat vectors that it shares."
"The technical support from Synopsys API Security Testing is amazing."
 

Cons

"Currently requires multiple tools, lacking one overall tool."
"I see a problem with SonarQube Server (formerly SonarQube) because the vulnerability assessment is continuous; if I fix some vulnerabilities today, they reappear in the next scan, and there will be completely different issues that need to be fixed."
"Dynamic scanning is missing and there are some issues with security scanning."
"SonarQube's detail in the security could be improved. It may be helpful to have additional details, with regards to Oracle PL/SQL. For example, it's neither as built nor as thorough as Java. For now, this is the only additional feature I would like to see."
"I am not very pleased with the technical debt computation, it's a bit arbitrary."
"Fortify is a better security tool; it is better than SonarQube in finding errors, and sometimes SonarQube doesn't find some of the errors that Fortify is able to find."
"It utilizes a lot of resources from the servers. I think this issue should be resolved because it takes approx 20% of the CPU utilization."
"The tool needs to be more compatible with C/C++ language"
More SonarQube cons
"The solution required us to use our team and we spoke to Synopsys API Security Testing's support to do the implementation. We use two people from our team for the implementation. and one person for maintenance."
"We haven't covered all the areas yet in our business. It's still being scaled up within the organization. We've probably covered 10 percent of the business. I don't think we've seen a proper ROI yet."
 

Pricing and Cost Advice

"I use the full trial version of SonarQube."
"The current pricing is quite cheap."
"The price of this solution is more expensive than competitors. However, it works better than competitors."
"This solution is free."
"I am satisfied with the pricing."
"I am using the free version of the solution."
"We're using an older version because it is the open-source flavor of it and we can continue using it at no cost. We're not paying any licensing at all, which was another factor in choosing this route so that we can learn and grow with it and not be committed to licenses and other similar things. If we choose to get something else, we have to relearn, but we don't have to relicense. Basically, we're paying no license costs."
"We use the tool's community edition."

SonarSource Sàrl

AppSec testing optimized for the needs of API developers
APIs provide open, flexible interfaces that enable applications and services to talk to each other. But these characteristics can also make it difficult to build secure software—and even more difficult for traditional AppSec tools to test it.
