Nice interface, quick to deploy, and easy to expand

This is the first time I've used this kind of software. It was the only one we could apply to analyze with MISRA rules. At my new company, I tried to use Klocwork. I tried to use it, just once so I cannot compare it exactly with CodeSonar. I also have a plugin for my Visual Studio and I try to make it work. It's not easy, however, I don't think that we have this kind of functionality with CodeSonar. It can do some incremental analysis. However, since this feature is also available on CodeSonar, it would be a good idea to have a plugin on Visual Studio just to have a quick analysis.

Though a stable tool, the UI needs improvement

Kiuwan can improve its UI a little more. The user experience can be made better. Kiuwan offers a user interface that is similar to the one offered by Windows 7 or Windows 98, which I saw when I ran the tool and tried to scan the repository to find the security issues. The product's UI has certain shortcomings, where improvements are required.

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 CodeSonar is the catching of dead code. It is helpful."

"CodeSonar’s most valuable feature is finding security threats."

"It has been able to scale."

"What I like best about CodeSonar is that it has fantastic speed, analysis and configuration times. Its detection of all runtime errors is also very good, though there were times it missed a few. The configuration of logs by CodeSonar is also very fantastic which I've not seen anywhere else. I also like the GUI interface of CodeSonar because it's very user friendly and the tool also shows very precise logs and results."

"The tool is very good for detecting memory leaks."

"The most valuable features of CodeSonar were all the categorized classes provided, and reports of future bugs which might occur in the production code. Additionally, I found the buffer overflow and underflow useful."

"There is nice functionality for code surfing and browsing."

"It provides value by offering options to enhance both code quality and the security of the company."

"The most valuable feature is the time to resolution, where it tells you how long it is going to take to get to a zero-base or a five-star security rating."

"We use Kiuwan to locate the source of application vulnerabilities."

"I find it immensely helpful because it's not just about generating code; it's about ensuring efficiency in the execution."

"I personally like the way it breaks down security vulnerabilities with LoC at first glance."

"Lifecycle features, because they permit us to show non-technical people the risk and costs hidden into the code due to bad programming practices."

"I like that I can scan the code without sending it to the Kiuwan cloud. I can do it locally on my device. When the local analyzer finishes, the results display on the dashboard in the cloud. It's essential for security purposes to be able to scan my code locally."

"I have found the security and QA in the source code to be most valuable."

Cons

"In a future release, the solution should upgrade itself to the current trends and differentiate between the languages. If there are any classifications that can be set for these programming languages that would be helpful rather than having everything in the generic category."

"There could be a shared licensing model for the users."

"It was expensive."

"In terms of areas for improvement, the use case for CodeSonar was good, but compared to other tools, it seems CodeSonar isn't a sound static analysis tool, and this is a major con I've seen from it. Right now, in the market, people prefer sound static analysis tools, so I would have preferred if CodeSonar was developed into a sound static analysis tool formally, in terms of its algorithms, so then you can see it extensively used in the market because at the moment, here in India, only fifty to sixty customers use CodeSonar. If the product is developed into a sound static analysis tool, it could compete with Polyspace, and from its current fifty customers, that number could go up to a hundred."

"It would be beneficial for the solution to include code standards and additional functionality for security."

"The scanning tool for core architecture could be improved."

"CodeSonar could improve by having better coding rules so we did not have to use another solution, such as MISRA C."

"The integration process could be improved. It'll also help if it could generate reports automatically. But I'm not sure about the effectiveness of the reports. This is because, in our last project, we still found some key issues that weren't captured by the Kiuwan report."

"The solution seems to give us a lot of false positives. This could be improved quite a bit."

"It would be beneficial to streamline calls and transitions seamlessly for improved functionality."

"Integration of the programming tools could be improved."

"In Kiuwan there are sometimes duplicates found in the dependency scan under the "insights" tab. It's unclear to me why these duplicates are appearing, and it would be helpful if the application teams could investigate further."

"The development-to-delivery phase."

"It could improve its scalability abilities."

"The QA developer and security could be improved."

Pricing and Cost Advice

"Our organization purchased a license to use the solution."

"Pricing is a bit costly."

"The solution's price depends on the number of licenses needed and the source code for the project."

"The application’s pricing is high compared to other tools."

"It follows a subscription model. I think the price is somewhere in the middle."

"This solution is cheaper than other tools."

"The price of Kiuwan is lower than that of other tools on the market."

"Check with your account manager."

"Kiuwan is an open-source solution and free to use."

"I recommend contacting a sales person who will create the best plan payment plan for you, as we did."

"Nothing special. It's a very fair model."

I'm not entirely sure about the price and business aspects, but I assume Checkmarx might be less expensive. I think Checkmarx might offer more affordable options, especially in its smaller business...
