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

"SonarQube is one of the more popular solutions because it supports 29 languages."
"There are many options and examples available in the tool that help us fix the issues it shows us."
"The stability is good."
"We were trying to serve two purposes; work quality and code security, with one tool."
"SonarQube is admin friendly."
"The most valuable features are the segregation containment and the suspension of product services."
"I would recommend SonarQube to other users as it is a good solution and the security issues we experienced are being fixed."
"It automatically scans for code, detects vulnerabilities, and generates daily reports."
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

"A robust credential scanner would be a huge bonus as it would remove the need for yet another niche product with additional cost, also gives the benefit of a single pane of glass view, although we still need WhiteSource Bolt for third-party library scanning."
"Although it has Sonar built into it, it is still lacking. Customization features of identifying a particular attack still need to be worked on. To give you an example: if we want to scan and do a false positive analysis, those types of features are missing. If we want to rescan something from a particular point that is a feature that is also missing. It’s in our queue. That will hopefully save a lot of time."
"For improvement, this solution could be offered on Docker and the cloud and the support for this solution could be improved. Customizing rules could also be made simpler."
"In discussions with the security team, there are many other products that are available that perform better."
"The exporting capabilities could be improved. Currently, exporting is fully dependent on the SonarQube environment."
"There are a lot of features missing in the free version of SonarQube that I want to have that already exist in Checkmarx."
"There is need for support for the additional languages and ease of use in adding new rules for detecting issues."
"I think the code security can be improved."
More SonarQube cons
"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."
"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."
 

Pricing and Cost Advice

"I do not know about the pricing as I am using the community edition, which is free. But I compared the pricing with Sigma, and it is higher than SonarQube."
"The licence is standard open source licensing"
"The price of the solution could be reduced."
"A low cost long-term solution for non-critical situations."
"The current pricing is quite cheap."
"It is very expensive. Its price should be improved."
"Compared to similar solutions, SonarQube was more accessible to us and had more benefits, with regards to size of the code base and supported languages. Apart from the Enterprise licensing fee, there are no additional costs."
"Get the paid version which allows the customized dashboard and provides technical support."

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.
