Resolving critical software issues demands faster implementation and better integration
We use Coverity primarily to find issues such as software bugs and memory leaks, especially in C++ and C# projects. It helps us identify deadlocks, synchronization issues, and product crashes Coverity has been instrumental in resolving product crashes by detecting various issues like deadlocks.…

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

"In my opinion, the most effective Coverity feature for identifying critical vulnerabilities is the extra checks, which offers deep analysis."
"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 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."
"Ease of development teams to adopt."
"The most valuable feature is the integration with Jenkins."
"One of the most valuable features is Contributing Events. That particular feature helps the developer understand the root cause of a defect. So you can locate the starting point of the defect and figure out exactly how it is being exploited."
"The reporting feature is up to the mark."
"It provides reports about a lot of potential defects."
"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."
"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."
"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."
 

Cons

"The product lacks sufficient customization options."
"We'd like it to be faster."
"The solution needs to improve its false positives."
"SCM integration is very poor in Coverity."
"Its price can be improved. Price is always an issue with Synopsys."
"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."
"Reporting engine needs to be more robust. Custom reporting is a must have."
"They could improve the usability. For example, how you set things up, even though it's straightforward, it could be still be easier."
"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."
"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 requires understanding the Defensics protocol."
 

Pricing and Cost Advice

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