Lets you find defects during the development phase, so you don't have to wait till the development is over to find and address flaws

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.

Automated code reviews and good scalability with custom rule adaptability

We use Semgrep to check custom user pipelines and test their claims for any vulnerabilities. We process the code by passing it through the testing process for any operability issues before sending feedback to the developers and providing the final product. This is part of the static testing…

Quotes from Members

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

Pros

"On-the-fly analysis and incremental analysis are the best parts of Klocwork. Currently, we are using both of these features very effectively."

"The ability to create custom checkers is a plus."

"The tool helps the team to think beforehand about corner cases or potential bugs that might arise in real-time."

"The reporting helps us understand the trend of our results and whether we improve over time. We can see the history within Klocwork's server architecture and know that we're making things better. It creates a great story for our management. We can demonstrate value and how our software is developing over time."

"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."

"The most valuable feature of Klocwork is its reduced setup time."

"One can increase the number of vendors, so the solution is scalable."

"There is a central Klocwork server at our headquarter in France so we connect the client directly to the server on-premises remotely."

More Klocwork pros

"The most valuable feature is the ability to write our custom rules."

Cons

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

"Modern languages, such as Angular and .NET, should be included as a part of Klocwork. They have recently added Kotlin as a part of their project, but we would like to see more languages in Klocwork. That's the reason we are using Coverity as a backup for some of the other languages."

"I believe it should support more languages, such as Python and JavaScript."

"Every update that we receive requires of us a lengthy and involved process."

"There are too many warnings, and it requires expertise to determine the correct category for them."

"Klocwork has to improve its features to stay ahead of other free solutions."

"Klocwork does have a problem with true positives. It only found 30% of true positives in the Juliet test case."

"I would like to see better codes between projects and a more user-friendly desktop in the next release."

More Klocwork cons

"There should be more information on how to acquire the system, catering to beginners in application security, to make it more user-friendly."

Pricing and Cost Advice

"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."

"This solution offers competitive pricing."

"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."

"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."

"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 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."

"Klocwork should not to be quite so heavy handed on the licensing for very specific programs."

"Licensing fees are paid annually, but they also have a perpetual license."
