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.

Has a great quality gate feature and improves the code coverage in your core base

We would like to have more visibility and more documentation, starting with the installation. It needs to be more standardized and explain all the features. We'd also like to get an idea of the level of stability we can get for our larger-sized projects. The notifications from the channel queue can be improved including email notifications. We currently rely on getting those notifications passed onto us and that should not be the case. The customization of different languages would also be helpful. If all the above could be implemented, SonarQube would be the best vulnerability security scanning tool.

Quotes from Members

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

Pros

"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."

"We like using the static analysis and code refactoring, which are very valuable because of our requirements to meet safety critical levels and reliability."

"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."

"Technical support is quite good."

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

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

"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

"It is an easy tool that you can deploy and configure. After that you can measure the history of your obligation and integrate it with other tools like GitLab or GitHub or Azure DevOps to do quality code analysis."

"The SonarQube dashboard looks great."

"SonarQube's unit test coverage and exhaustive information at the module, project, and overall code repo levels are quite good."

"I am only interested in the security features in SonarQube. There are plenty of features other features, such as test coverage, code anomalies, and pointer access are handled by the business logic teams. They get the reports and they have to fix them in JIRA or Bugzilla."

"The most valuable features are that it is user-friendly, easy to access, and they provide good training files."

"Some of the static code analysis capabilities are the most beneficial."

"This solution has helped with the integration and building of our CICD pipeline."

"It's a great product. If you are in a hurry and just want to focus on the functional requirements of any kind of project, SonarQube is highly helpful. It enables the developers to code securely. SonarQube has a Community edition, which is open source and free. There are also three proprietary or paid versions: Enterprise edition, Data Center edition, and Developer edition."

Cons

"This solution could be improved if they offered support of more languages including Ada and Golang. They currently only support seven languages."

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

"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."

"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."

"Now the only issue we have is that whenever we need to get the code we have to build it first. Then we can get the report."

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

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

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

More Klocwork cons

"The learning curve can be fairly steep at first, but then, it's not an entry-level type of application. It's not like an introduction to C programming. You should know not just C programming and how to make projects but also how to apply its findings to the bigger picture. I've had users who said that they wish it was easier to understand how to configure, but I don't know if that's doable because what it's doing is a very complicated thing. I don't know if it is possible to make a complicated thing trivially simple."

"It should be user-friendly."

"I would like to see more options for security, beyond the basics like SQL injection."

"It requires advanced heuristics to recognize more complex constructs that could be disregarded as issues."

"The interface could be a little better and should be enhanced."

"In terms of what can be improved, the areas that need more attention in the solution are its architecture and development."

"It would be a great add-on if SonarQube could update its database for vulnerabilities or plugging parts."

"There are times that we have the database crash. However, this might be an issue with how we have configured it and not a software issue. Apart from this, I do not see any issues with the solution."

Pricing and Cost Advice

"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."

"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."

"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."

"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."

"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."

"I do not know about the pricing as I am using the community edition, which is free. But I compared the pricing with Sigma, and it is higher than SonarQube."

"On the pricing side, it's 3,000 Euros for 1 million lines of code."

"SonarQube enterprise, I am not sure of the price but from what I understand they are charging a fee. It's is not clear if it is an annual fee or a one-off."

"I requested this license for one million lines of code and they accepted this."

"SonarQube is a fairly affordable solution for a larger scale if you have a specific role or specific department for secure code."

"We're using the Community Edition, and we don't pay for anything."

"I am satisfied with the pricing."

"The price of this solution is more expensive than competitors. However, it works better than competitors."
