Nice interface, quick to deploy, and easy to expand
This is the first time I've used this kind of software. It was the only one we could apply to analyze with MISRA rules. At my new company, I tried to use Klocwork. I tried to use it, just once so I cannot compare it exactly with CodeSonar. I also have a plugin for my Visual Studio and I try to make it work. It's not easy, however, I don't think that we have this kind of functionality with CodeSonar. It can do some incremental analysis. However, since this feature is also available on CodeSonar, it would be a good idea to have a plugin on Visual Studio just to have a quick analysis.

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 features of CodeSonar were all the categorized classes provided, and reports of future bugs which might occur in the production code."
"There is nice functionality for code surfing and browsing."
"What I like best about CodeSonar is that it has fantastic speed, analysis and configuration times. Its detection of all runtime errors is also very good, though there were times it missed a few. The configuration of logs by CodeSonar is also very fantastic which I've not seen anywhere else. I also like the GUI interface of CodeSonar because it's very user friendly and the tool also shows very precise logs and results."
"What I like best about CodeSonar is that it has fantastic speed, analysis and configuration times."
"It has helped us a lot with some issues and has helped us avoid bad code."
"It has been able to scale."
"CodeSonar’s most valuable feature is finding security threats."
"The most valuable features of CodeSonar were all the categorized classes provided, and reports of future bugs which might occur in the production code. Additionally, I found the buffer overflow and underflow useful."
"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."
"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."

Because of that, we can eliminate a lot of unwanted test cases, so we can execute the tests and complete them very quickly."
"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."
"The stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
 

Cons

"CodeSonar could improve by having better coding rules so we did not have to use another solution, such as MISRA C."
"CodeSonar could improve by having better coding rules so we did not have to use another solution, such as MISRA C."
"It would be beneficial for the solution to include code standards and additional functionality for security."
"In terms of areas for improvement, the use case for CodeSonar was good, but compared to other tools, it seems CodeSonar isn't a sound static analysis tool, and this is a major con I've seen from it."
"The MISRA guidelines were not appropriately reported and there were some flags or errors."
"In a future release, the solution should upgrade itself to the current trends and differentiate between the languages. If there are any classifications that can be set for these programming languages that would be helpful rather than having everything in the generic category."
"The scanning tool for core architecture could be improved."
"It was expensive."
"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."
"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."
"You can't implement proprietary ciphering algorithms, nor can you modify protocol models if you need to test customized public protocols."
"Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install."
"Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install."
"It requires understanding the Defensics protocol."
 

Pricing and Cost Advice

"The solution's price depends on the number of licenses needed and the source code for the project."
"The application’s pricing is high compared to other tools."
"Our organization purchased a license to use the solution."
"Pricing is a bit costly."
"Licensing is a bit expensive."
