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.

General Manager at a manufacturing company with 10,001+ employees
Has struggled with performance and integration but supports critical safety verification
Execution speed of the tests and generally the integration into AWS-driven CI work chains or workflows represent how it can be improved in my opinion. Performance issues plus license costs are two main driving factors. The CI environments that we use employ up to around 40,000 virtual CPUs per day in peak, running at the same time. We always have problems distributing licenses accordingly with other products. I can talk to the experts doing the integration, but as far as I know, I was involved with Polyspace Code Prover and we had a lot of difficulties integrating it into our Bazel-driven CI toolchain, plus integrating it on the AWS environments in Linux that we use. It was much more straightforward using Code Sonar there. The reason is the execution speed, integration with Azure and stuff, and pricing. The CI integration and maybe a better-suited license model for CI-driven execution are other areas I recommend improving. That's something we discussed with all of the software companies whose products we use, such as compilers. We have a lot of parallel builds, and each call to a license server is actually problematic in the long run.

Quotes from Members

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

Pros

"The whole package offers a lot of possibilities: add-ons for Eclipse, standalone clients, access via web site, support, documentation, command line."
"Klocwork's most valuable feature is the static code analysis feature, as it detects potential problems earlier to allow the developer to receive feedback quickly and then address issues before they become a problem."
"I recommend this tool as one of the best to be used for static analysis and should at least be tried."
"The most valuable feature of Klocwork is its reduced setup time."
"Technical support is quite good."
"On-the-fly analysis and incremental analysis are the best parts of Klocwork, and currently we are using both of these features very effectively."
"Klocwork is user-friendly, with a client-server architecture that provides all needed compliance."
"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."
"Polyspace Code Prover has made me realize it differs from other static code analysis tools because it runs the code. So it's quite distinct in that aspect."
"Efficiency and speed are the advantages I see in Code Sonar over Polyspace Code Prover."
"The product detects memory corruptions."
"When we work on safety modules, it is mandatory to fulfill ISO 26262 compliance. Using Prover helps fulfill the standard on top of many other quality checks, like division by zero, data type casts, and null pointer dereferences."
"Polyspace Code Prover is a very user-friendly tool."
"The outputs are very reliable."
 

Cons

"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."
"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."
"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."
"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."
"There are some false warnings found which eventually are not considered for a fix after the team reviewed the source code."
"I hope that in each new release they add new features relating to the addition of checkers, improving their analysis engines etc."
"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."
"Using Code Prover on large applications crashes sometimes."
"I'm still trying to use constraints with range propagation, but I can't get it to work properly, and I haven't found any documentation."
"One of the main disadvantages is the time it takes to initiate the first run."
"Automation could be a challenge."
"Because we had difficulties in efficiently integrating Polyspace Code Prover into our CI toolchain, these tests are mostly run manually and only occasionally."
"I'd like the data to be taken from any format."
"The tool has some stability issues."
 

Pricing and Cost Advice

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