Efficient and accurate scanning, and detailed analysis
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. Another issue I've encountered is that Kiuwan only looks at the version of components and doesn't take into account any workaround fixes that have been implemented at the code level. This can result in false positives being reported. Additionally, these issues are in the "insights" tab and not in the code base security aspect. Lastly, when muting findings that are false positives, there should be an option to see the only available at the code level rather than at the organization level because it can lead to missing vulnerabilities if they are muted at the org level. An additional feature that would be helpful is the ability to easily download reports from Kiuwan. Specifically, in the "insights" tab, we have been encountering an error when trying to download the PDF report. We are able to download the code-based security report, but not the insights report. This has been an ongoing issue for the past couple of months and would be beneficial if it could be resolved. My main recommendation would be to address the issues with downloading reports that we have been experiencing. Additionally, it would be helpful if Kiuwan could support a wider range of programming languages, as there are currently some that are not compatible with the tool. If the code of a particular application falls under the category which is not compatible with Kiuwan, then it will not be able to scan it.

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

"I've tried many open source applications and the remediation or correction actions that were provided by Kiuwan were very good in comparison."
"​We use Kiuwan to locate the source of application vulnerabilities."
"The most valuable feature of the solution stems from the fact that it is quick when processing and giving an output or generating a report."
"I like that it provides a detailed report that lets you know the risk index and the vulnerability."
"I personally like the way it breaks down security vulnerabilities with LoC at first glance."
"The solution offers very good technical support."
"Lifecycle features, because they permit us to show non-technical people the risk and costs hidden into the code due to bad programming practices."
"Software analytics for a lot of different languages including ABAP."
"On-the-fly analysis and incremental analysis are the best parts of Klocwork. Currently, we are using both of these features very effectively."
"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."
"The most valuable feature is the Incremental analysis."
"Technical support is quite good."
"The most valuable feature of Klocwork is its reduced setup time."
"The customer support team is very responsive, proactive, and engages in conversations to ensure our needs are met."
"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 best advantage of Klocwork is the reduced setup time."
 

Cons

"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."
"Integration of the programming tools could be improved."
"The integration process could be improved. It'll also help if it could generate reports automatically. But I'm not sure about the effectiveness of the reports. This is because, in our last project, we still found some key issues that weren't captured by the Kiuwan report."
"The QA developer and security could be improved."
"The solution seems to give us a lot of false positives. This could be improved quite a bit."
"It could improve its scalability abilities."
"Kiuwan's support has room for improvement. You can only open a ticket is through email, and the support team is outside of our country. They should have a support number or chat."
"I would like to see better integration with Azure DevOps in the next release of this solution."
"The way to define the rules is too complex. The definition/rules for static analysis could be automated according to various SILs, so as to avoid confusion."
"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."
"This solution could be improved if they offered support of more languages including Ada and Golang. They currently only support seven languages."
"Even though it does the job, there's room for feature enhancements, such as integrations with Git for better tracking and notifications."
"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 would like to see better codes between projects and a more user-friendly desktop in the next release."
"Every update that we receive requires of us a lengthy and involved process."
"Klocwork does have a problem with true positives. It only found 30% of true positives in the Juliet test case."
 

Pricing and Cost Advice

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