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

"For the moment, this is a solution that I could recommend."
"​We use Kiuwan to locate the source of application vulnerabilities."
"It provides value by offering options to enhance both code quality and the security of the company."
"I have found the security and QA in the source code to be most valuable."
"I like that it provides a detailed report that lets you know the risk index and the vulnerability."
"This solution helps us to catch issues early on, and find problems that we never knew we had."
"I've tried many open source applications and the remediation or correction actions that were provided by Kiuwan were very good in comparison."
"We switched because Kiuwan covers the entire SDLC; provides direct information to act upon, for the developer, architects, QA, CIO and CISO, in a few seconds; automatically, fully integrated in any CI/CD setup."
"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."
"I like not having to dig through false positives. Chasing down a false positive can take anywhere from five minutes for a small easy one, then something that is complicated and goes through a whole bunch of different class cases, and it can take up to 45 minutes to an hour to find out if it is a false positive or not."
"Klocwork has reduced the manual analysis for a lot of scenarios like checking for internal standards and has saved a lot of time in developing code through the on the fly analysis mode."
"It's integrated into our CI, continuous integration."
"The most valuable feature of Klocwork is its reduced setup time."
"Klocwork is a good product, but keep in mind that before building the code you have to get a report."
"Technical support is quite good."
"The ability to create custom checkers is a plus."
 

Cons

"The configuration hasn't been that good."
"More languages and frameworks would enhance this tool."
"It would be beneficial to streamline calls and transitions seamlessly for improved functionality."
"The QA developer and security 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."
"I would like to see additional languages supported."
"The pricing and licensing models are poor."
"The development-to-delivery phase."
"There are many things that can be improved. The code used between projects is one of the very painful points in Klocwork."
"We bought Klocwork, but it was limited to one little program, but the program is now sort of failing. So, we have a license for usage on a program that is sort of failing, and we really can't use the license on anything else."
"I hope that in each new release they add new features relating to the addition of checkers, improving their analysis engines etc."
"I believe it should support more languages, such as Python and JavaScript."
"Klocwork has to improve its features to stay ahead of other free solutions."
"The main problem is that since it only parses the code, the warnings or the problems that are given as a result of the report can sometimes require a lot of effort to analyze."
"Under NIST cybersecurity standards, we must address vulnerabilities within a specified time after discovering them. When we try to propagate those updates and fixes through the system, it would be nice if the clients could reconnect to the existing server or have the server dynamically updated in some way. I know that isn't easy, but maybe processes could be enhanced to make that more streamlined from a DevOps perspective."
"Every update that we receive requires of us a lengthy and involved process."
 

Pricing and Cost Advice

"Nothing special. It's a very fair model."
"The price of Kiuwan is lower than that of other tools on the market."
"It follows a subscription model. I think the price is somewhere in the middle."
"I recommend contacting a sales person who will create the best plan payment plan for you, as we did."
"Check with your account manager."
"Kiuwan is an open-source solution and free to use."
"This solution is cheaper than other tools."
"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."
"This solution offers competitive pricing."
"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."
"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."
"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."
"Licensing fees are paid annually, but they also have a perpetual license."
"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."
