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

"The solution was very simple to set up."
"Coverity provides excellent compliance and other features, which is a very good part."
"Coverity is helping us identify some of the critical defects at the early stages of the development life cycle, so overall, it is giving us a greater ROI and making our application more mature and robust."
"The product is easy to use."
"Coverity is quite stable and we haven’t had any issues or any downtime."
"Coverity is easy to use and easy to integrate with CI."
"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"
"The app analysis is the most valuable feature as I know other solutions don't have that."
"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 stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
"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."
"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... Because of that, we can eliminate a lot of unwanted test cases, so we can execute the tests and complete them very quickly."
 

Cons

"Reporting engine needs to be more robust."
"Coverity is not stable."
"Coverity could improve the ease of use. Sometimes things become difficult and you need to follow the guides from the website but the guides could be better."
"The solution is a bit complex to use in comparison to other products that have many plugins."
"The setup takes very long."
"Ideally, it would have a user-based license that does not have a restriction in the number of lines of code."
"Reporting engine needs to be more robust. Custom reporting is a must have."
"It would be great if we could customize the rules to focus on critical issues."
"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."
"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."
"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."
 

Pricing and Cost Advice

"I would rate Coverity's pricing as a nine out of ten. It's already very expensive, and it's a problem for us to get more licenses due to the price. The pricing model has some good aspects - for example, a personal license gives access to all languages without code limitations, which is better than some competitors. However, it's still a lot of money for us to spend."
"The tool was fairly priced."
"The licensing fees are based on the number of lines of code."
"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."
"The pricing is very reasonable compared to other platforms. It is based on a three year license."
"I would rate the tool's pricing a one out of ten."
"Coverity is very expensive."
"Licensing is a bit expensive."
