Helps us identify security vulnerabilities in the development phase and provides a plugin for the developer IDE
The initial setup is good. When I use the product to scan the code in the DevOps pipeline, the issue coverage can be greater, which can help speed up risk identification in the CI/CD pipeline. That is one area where improvement can be made. Corresponding steps can be taken for that. It integrates with most of the tools, like ticketing tools, configuration tools, Jenkins, and the pipeline. That is fantastic.

Product security tests for switches and router sections
Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install. What I see in the documentation isn't that. Even if something doesn't malfunction, sometimes it is hard to install and execute. The product needs video documentation. This would help a lot more.

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 the integration with Jenkins."
"The most valuable feature of Coverity is its interprocedural analysis, which is advantageous because it compares favorably with other tools in terms of security and code analysis."
"The tool as it is can be used for code quality improvement."
"The solution has helped to increase staff productivity and improved our work significantly by approximately 20 percent."
"In my opinion, the most effective Coverity feature for identifying critical vulnerabilities is the extra checks, which offers deep analysis."
"It is a scalable solution."
"The ability to scan code gives us details of existing and potential vulnerabilities. What really matters for us is to ensure that we are able to catch vulnerabilities ahead of time."
"If you have enough budget, it is one of the best solutions right now."
"ROI was 100%. Since there are no product suites available that provide the level of testing available with Codenomicon, the development, quality and security assurance departments know that the investment was correct."
"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."
"Simple and straightforward GUI."
"The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."
"Whatever the test suit they give, it is intelligent; it will understand the protocol and it will generate the test cases based on the protocol: protocol, message sequence, protocol, message structure, and because of that, we can eliminate a lot of unwanted test cases so we can execute the tests and complete them very quickly."
"The stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
 

Cons

"We'd like it to be faster."
"The product should include more customization options. The analytics is not as deep as compared to SonarQube."
"Coverity is far from perfection, and I'm not 100 percent sure it's helping me find what I need to find in my role. We need exactly what we are looking for, i.e. security errors and vulnerabilities. It doesn't seem to be reporting while we are changing our code."
"There is an extra step in my organization that involves uploading to servers, which adds overhead."
"My personal opinion is that the webpage of the last version of Coverity is not very easy to use."
"The setup takes very long."
"It is an expensive solution. Their sales team is very arrogant."
"Sometimes it's a bit hard to figure out how to use the product’s UI."
"It requires understanding the Defensics protocol."
"Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install."
"You can't implement proprietary ciphering algorithms, nor can you modify protocol models if you need to test customized public protocols."
"It does not support the complete protocol stack. There are some IoT protocols that are not supported and new protocols that are not supported."
"Sometimes, when we are testing embedded devices, when we trigger the test cases, the target will crash immediately. It is very difficult for us to identify the root cause of the crash because they do not provide sophisticated tools on the target side. They cover only the client-side application... They do not have diagnostic tools for the target side. Rather, they have them but they are very minimal and not very helpful."
 

Pricing and Cost Advice

"The tool's price is somewhere in the middle. It's neither cheap nor expensive. I would rate the pricing a five out of ten."
"The price is competitive with other solutions."
"Coverity is very expensive."
"The solution is affordable."
"The tool was fairly priced."
"This is a pretty expensive solution. The overall value of the solution could be improved if the price was reduced. Licensing is done on an annual basis."
"Coverity is quite expensive."
"Coverity’s price is on the higher side. It should be lower."
"Licensing is a bit expensive."
