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

"Provides software security, and helps to find potential security bugs or defects."
"It's very stable."
"The most valuable feature is that there were not a whole lot of false positives, at least on the codebases that I looked at."
"Considering the analysis part and the benchmarking process involving the product that my company carried out, the solution is good for finding bugs and violations"
"We were very comfortable with the initial setup."
"The most valuable feature is the ability to find vulnerabilities in our code."
"Coverity provides developers with a good, best practice, coding advice, and tracks risks of poor coding quality."
"It's pretty stable. I rate the stability of Coverity nine out of ten."
"The stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
"Simple and straightforward GUI."
"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."
"The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."
"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."
 

Cons

"We'd like it to be faster."
"This is a pretty expensive solution. The overall value of the solution could be improved if the price was reduced."
"Coverity is not stable."
"Sometimes it's a bit hard to figure out how to use the product’s UI."
"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."
"Coverity is too costly, which is why we are trying other tools."
"I am not a fan of using both SOAP and REST APIs and Coverity offers a mix of functionality depending on the interface used."
"The solution could use more rules."
"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."
"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."
"It requires understanding the Defensics protocol."
 

Pricing and Cost Advice

"The price is competitive with other solutions."
"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."
"I would rate the tool's pricing a one out of ten."
"Coverity is quite expensive."
"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."
"The solution's pricing is comparable to other products."
"Coverity’s price is on the higher side. It should be lower."
"The solution is affordable."
"Licensing is a bit expensive."
