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.

There's a feature in Klocwork called 'on-the-fly analysis', which helps developers to find and fix the defects at the time of development itself.

Klocwork's most valuable feature is the static code analysis feature. It detects the potential problem earlier to allow the developer to receive feedback quickly and then address it before it becomes a problem.

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.

Even though it does the job, there's room for feature enhancements, such as integrations with Git for better tracking and notifications.

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.

What needs improvement in Klocwork, compared to other products in the market, is the dashboard or reporting mechanisms that need to be a bit more flexible. The Klocwork dashboard could be improved. Though it's good, it's not as good as some of the other products in the market, which is a problem. The reporting could be more detailed and easier to sort out because sorting in Klocwork could be a bit more time-consuming, mainly when sorting defects based on filters, compared to how it's done on other tools such as Coverity.
