Lead Information Security at GEP Worldwide at ReBIT
Helps us identify security vulnerabilities in the development phase and provides a plugin for the developer IDE
The initial setup is good. When I use the product to scan the code in the DevOps pipeline, the issue coverage can be greater, which can help speed up risk identification in the CI/CD pipeline. That is one area where improvement can be made. Corresponding steps can be taken for that. It integrates with most of the tools, like ticketing tools, configuration tools, Jenkins, and the pipeline. That is fantastic.

Product security tests for switches and router sections
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 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."
"If they have a cluster structure, then definitely they should use Coverity."
"In my opinion, the most effective Coverity feature for identifying critical vulnerabilities is the extra checks, which offers deep analysis."
"The solution was very simple to set up."
"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."
"We were very comfortable with the initial setup."
"Coverity provides excellent compliance and other features, which is a very good part."
"Coverity integrates with issue-tracking systems like Jira and provides email notifications, alerts, and other features."
"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."
"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."
"The stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
 

Cons

"They could improve the usability. For example, how you set things up, even though it's straightforward, it could be still be easier."
"Their technical support isn't so good. That needs improvement. They don't address the problems I bring up. It's not a priority for them."
"The price is a concern, and there are a lot of false positives coming through."
"We'd like it to be faster."
"The solution's user interface and quality gate could be improved."
"We actually specified several checkers, but we found some checkers had a higher false positive rate. I think this is a problem. Because we have to waste some time is really the issue because the issue is not an issue. I mean, the tool pauses or an issue, but the same issue is the filter now.Some check checkers cannot find some issues, but sometimes they find issues that are not relevant, right, that are not really issues. Some customisation mechanism can be added in the next release so that we can define our Checker. The Modelling feature provided by Coverity helps in finding more information for potential issues but it is not mature enough, it should be mature. The fast testing feature for security testing campaign can be added as well. So if you correctly integrate it with the training team, maybe you can help us to find more potential issues."
"Sometimes it's a bit hard to figure out how to use the product’s UI."
"Coverity is not stable but it is sufficient for our organization's requirements."
"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."
"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."
 

Pricing and Cost Advice

"I would rate the pricing a six out of ten, where one is low, and ten is high price."
"The solution is affordable."
"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."
"The solution's pricing is comparable to other products."
"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 rate Coverity's price a ten on a scale of one to ten, where one is cheap and ten is expensive."
"Offers varying prices for different companies"
"Licensing is a bit expensive."
