Using tools for compliance is beneficial but cost concerns persist
We have been using Coverity for quite a long period. It has been fine for our needs. I would rate Coverity between eight to nine, though the cost is high. I would rate their support from Coverity as six. That is the main complaint, but we still appreciate having it.

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

"We were very comfortable with the initial setup."
"This solution is easy to use."
"The most valuable feature is the integration with Jenkins."
"The app analysis is the most valuable feature as I know other solutions don't have that."
"I encountered a bug with Coverity, and I opened a ticket. Support provided me with a workaround. So it's working at the moment, or at least it seems to be."
"It provides reports about a lot of potential defects."
"The solution effectively identifies bugs in code."
"It's very stable."
"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."
"The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."
"Simple and straightforward GUI."
"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... 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."
 

Cons

"When I put my code into Coverity for scanning, the code information of the product is in the system. The solution could be improved by providing a SBOM, a software bill of material."
"The level of vulnerability that this solution covers could be improved compared to other open source tools."
"Sometimes it's a bit hard to figure out how to use the product’s UI."
"Reporting engine needs to be more robust."
"The solution's user interface and quality gate could be improved."
"Coverity's implementation cycle is very slow when integrating changes, especially for problems related to event handling and memory leaks."
"The setup takes very long."
"Zero-day vulnerability identification can be an add-on feature that Coverity can provide."
"It requires understanding the Defensics protocol."
"You can't implement proprietary ciphering algorithms, nor can you modify protocol models if you need to test customized public protocols."
"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."
"Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install."
"It does not support the complete protocol stack. There are some IoT protocols that are not supported and new protocols that are not supported."
 

Pricing and Cost Advice

"It is expensive."
"Coverity is quite expensive."
"I rate Coverity's price a ten on a scale of one to ten, where one is cheap and ten is expensive."
"Offers varying prices for different companies"
"Depending on the usage types, one has to opt for different types of licenses from Coverity, especially to be able to use areas like report viewing or report generation."
"Coverity is very expensive."
"The pricing is very reasonable compared to other platforms. It is based on a three year license."
"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."
"Licensing is a bit expensive."

What needs improvement with Coverity?
The price is a concern, and there are a lot of false positives coming through. Support with Coverity is adequate, but they take a longer time to respond. The core support is not straightforward, an...
