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. What I'd like added in the next release of Klocwork is the peer code review Cahoots which used to be a part of Klocwork, and the architecture analysis and both have been taken out of Klocwork. I found the two critical for specific deployments, so if those can be brought back to Klocwork, that would be very good.

I utilize Klocwork for identifying defects and early vulnerabilities in the code, conducting code checks, and categorizing and fixing failures The most valuable feature of Klocwork is its reduced setup time. It takes around half a day to set up, making it easier to debug and categorize failures.…

It is not a panacea, because there is no tool that is a panacea. 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. It is a terrrible shame. 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. I would like to have a tool developed by a vendor that picks out all of the NSA Juliet Test Suite cases, then is generous with the licensing. It might be expensive, but it is generous. Klocwork does have a problem with true positives. It only found 30% of true positives in the Juliet test case.

Valuable Features

Klocwork excels in static code analysis with minimal false positives and rapid setup. Users appreciate its custom checker creation, on-the-fly analysis, and integration with various IDEs and CI systems. The incremental analysis and extensive language support enhance development efficiency. Teams value the collaboration fostered by the server-client build and the insightful reporting. Klocwork's capability to identify security threats and errors early in development ensures high-quality, safe code.

"The customer support team is very responsive, proactive, and engages in conversations to ensure our needs are met."
"The best advantage of Klocwork is the reduced setup time."
"The most valuable feature of Klocwork is its reduced setup time."

Room for Improvement

Klocwork needs to improve global variable tracking and reduce false positives. Enhancements in language support and licensing flexibility are required. The user interface, particularly the dashboard, should be more intuitive and integrated with DevOps tools. Reducing analysis time and including automated rule definitions would boost efficiency. Addressing false alarms and offering dynamic analysis capabilities can enhance usefulness. More comprehensive language support, including modern languages, is desired, along with smoother updates and server integration.

"Even though it does the job, there's room for feature enhancements, such as integrations with Git for better tracking and notifications."
"There are too many warnings, and it requires expertise to determine the correct category for them."
"Klocwork sometimes provides too many additional warnings which require expertise to manage."

Pricing

Klocwork's pricing and licensing are seen as competitive and flexible, offering options for both fixed and floating servers. Some users find the initial setup costly but acknowledge its value. Licensing fees can be annual or perpetual, with costs varying based on deployment and license type. While some find Klocwork expensive compared to newer tools like Microsoft Visual Studio, SMBs consider it affordable. The solution is typically cheaper than alternatives like Coverity.

"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."
"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."
