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

"Coverity gives advisory and deviation features, which are some of the parts I liked."
"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."
"I like Coverity's capability to scan codes once we push it. We don't need more time to review our colleagues' codes. Its UI is pretty straightforward."
"The most valuable feature is that there were not a whole lot of false positives, at least on the codebases that I looked at."
"Coverity provides developers with a good, best practice, coding advice, and tracks risks of poor coding quality."
"The solution has helped to increase staff productivity and improved our work significantly by approximately 20 percent."
"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."
"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."
"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."
"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."
"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 stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
 

Cons

"We use GitHub and Gitflow, and Coverity does not fit with Gitflow. I have to create a screen for our branches, and it's a pain for developers. It has been difficult to integrate Coverity with our system."
"My personal opinion is that the webpage of the last version of Coverity is not very easy to use."
"The solution needs to improve its false positives."
"There should be additional IDE support."
"This is a pretty expensive solution. The overall value of the solution could be improved if the price was reduced."
"The product should include more customization options. The analytics is not as deep as compared to SonarQube."
"We're currently facing a primary challenge with automation using Coverity. Each developer has a license and can perform manual checks, and we also have a nightly build that analyzes the entire software. The main issue is that the tool can't look behind submodules in our code base, so it doesn't see changes stored there."
"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."
"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."
"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."
"You can't implement proprietary ciphering algorithms, nor can you modify protocol models if you need to test customized public protocols."
 

Pricing and Cost Advice

"The solution's pricing is comparable to other products."
"Coverity’s price is on the higher side. It should be lower."
"I would rate the pricing a six out of ten, where one is low, and ten is high price."
"Coverity is very expensive."
"The pricing is on the expensive side, and we are paying for a couple of items."
"The licensing fees are based on the number of lines of code."
"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."
"Licensing is a bit expensive."
