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.

Experience with compliance improvements and efficiency boosts but static analysis engine shows a need for enhancement
One area for improvement is that when customers use different static analysis tools, they report more issues compared to Klocwork. The static analysis engine of Klocwork has areas that need improvement. Customers using different static analysis tools report more issues than with Klocwork, indicating that Klocwork's engine is not as superior. Klocwork should be able to analyze large codebases efficiently, supporting a desktop version for periodic small delta changes before pushing to the server.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"​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."
"Saving time and money by automatically identifying problems is unbelievable."
"Kiuwan has enabled us to give our customers peace of mind through early identification of code vulnerabilities and remediation before delivery to the customer."
"The feature that I have found the most valuable in Kiuwan is the speed of scanning. Compared to other SaaS tools I have used, Kiuwan is much quicker in performing scans. I have not yet used it on a large code base, but from what I have experienced, it is efficient and accurate. Additionally, I have used it both manually and in an automated pipeline, and both methods have been effective. The speed of scanning is what makes it valuable to me."
"Customer service is excellent."
"With Kiuwan, we were able to help our clients get a better visibility of their development activities and to mitigate risks."
"Lifecycle features, because they permit us to show non-technical people the risk and costs hidden into the code due to bad programming practices."
"Unlike other static code analysis tools, Klocwork integrates seamlessly into desktop IDEs, build systems, continuous integration tools, and any team's natural workflow."
"The ability to create custom checkers is a plus."
"Klocwork has caught up to Fortify and surpassed them; they have a higher detection and false positive rate than Fortify does."
"Technical support is quite good."
"First will be the on-the-fly analysis as it is reducing the time for developing code and report generation."
"The best advantage of Klocwork is the reduced setup time."
"The most valuable feature of Klocwork is finding defects while you're doing the coding. For example, if you have an IDE plug-in of Klocwork on Visual Studio or Eclipse, you can find the faults; similar to using spell check on Word, you can find out defects during the development phase, which means that you don't have to wait till the development is over to find the flaws and address the deficiencies. I also find language support in Klocwork good because it used to support only C, C++, C#, and Java, but now, it also supports Java scripts and Python."
"Now Klocwork has completely removed this and we are very easily checking our internal standards."
 

Cons

"It could improve its scalability abilities."
"More languages and frameworks would enhance this tool."
"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 development-to-delivery phase."
"DIfferent languages, such Spanish, Portuguese, and so on."
"The rate of false positives, where it reports issues that are not really issues, can be improved."
"We faced a lot of problems with the initial setup and support gave us difficulties around the installation."
"The product's UI has certain shortcomings, where improvements are required."
"Klocwork sometimes provides too many additional warnings which require expertise to manage."
"There are too many warnings, and it requires expertise to determine the correct category for them."
"The way to define the rules is too complex."
"There are other solutions on the market such as Microsoft Visual Studio. They have been adding more static code analysis features that come for free."
"Global variables sometimes generate false positives. Variables with global scopes sometimes produce false positives, which is annoying and time consuming because I get violations from Klocwork which after personal analysis turn out to be not true."
"Support for AUTOSAR C++14 by adding a new taxonomy that you can use to ensure compliance with the AUTOSAR C++14 Standard, release 18-03."
"Every update that we receive requires of us a lengthy and involved process."
"I hope that in each new release they add new features relating to the addition of checkers, improving their analysis engines etc."
 

Pricing and Cost Advice

"Check with your account manager."
"This solution is cheaper than other tools."
"Nothing special. It's a very fair model."
"The price of Kiuwan is lower than that of other tools on the market."
"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."
"It follows a subscription model. I think the price is somewhere in the middle."
"There are other solutions on the market such as Microsoft Visual Studio. They have been adding more static code analysis features that come for free. It is getting better all the time. That is one of the possibilities is that we've been considering that we may stop using the Klocwork because it doesn't give us any added value."
"Klocwork should not to be quite so heavy handed on the licensing for very specific programs."
"The limitation that we have is that Klocwork is licensed to certain programs, and if you want to license them to other programs, you have to pay more money."
"This solution offers competitive pricing."
"When it comes to licensing, the solution has two packages, one for a fixed and the other for a floating server, with the former being more cost effective than the latter."
"Klocwork is still tight on their licensing. If Klocwork would loosen up on the licensing, and where the license could be used, and how many different programs could be run on it, then we have several development programs that I would love to be able to use it for going forward."
"Licensing fees are paid annually, but they also have a perpetual license."
"The pricing for Klocwork is very competitive if you compare it from apple to apple. It has competitive pricing regarding the licensing model and the per-license cost. Klocwork isn't a high-end investment for anyone deploying it; even SMBs can afford it. The Klocwork cost per user would depend on the license type, so I'm unable to mention a ballpark figure because it would depend on the type of installation and how the deployment will be, and the nodes to give an accurate calculation or figure. The total price depends on the package, so my company could never publish pricing for Klocwork on the website. My team first collects information from potential clients on the deployment scenario, project environment, etc., before suggesting a package for Klocwork. My rating for Klocwork in terms of pricing is a five because of its flexible license models. There's a license model for every type of organization, whether small, midsize, or enterprise, so it's a five out of five for me."
