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 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."
"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."
"It has the lowest false positives."
"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 app analysis is the most valuable feature as I know other solutions don't have that."
"This product has definitely helped our organization, and based on what I have heard from the development team, they have found a lot of issues before code goes into production."
"The security analysis features are the most valuable features of this solution."
"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."
"The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."
"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."
"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."
"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

"SCM integration is very poor in Coverity."
"The reporting tool integration process is sometimes slow."
"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."
"The price is a concern, and there are a lot of false positives coming through."
"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."
"I would like to see integration with popular IDEs, such as Eclipse."
"The solution needs to improve its false positives."
"It is an expensive solution. Their sales team is very arrogant."
"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."
"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."
"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."
"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."
 

Pricing and Cost Advice

"The price is competitive with other solutions."
"I rate Coverity's price a ten on a scale of one to ten, where one is cheap and ten is expensive."
"Coverity is very 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."
"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."
"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 pricing is on the expensive side, and we are paying for a couple of items."
"Licensing is a bit expensive."
