Provides good security analysis and security identification within the source code

We integrate Checkmarx into our software development cycle using GitLab's CI/CD pipeline. Checkmark has been the most helpful for us in the development stage. The solution's incremental scanning feature has impacted our development speed. The solution's vulnerability detection is around 80% to 90% accurate. I would recommend Checkmarx to other users because it is one of the good tools for doing security analysis and security identification within the source code. Overall, I rate Checkmarx a nine out of ten.

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.

Easy to integrate and has a plug-in that supports both C and C++ languages

The product provides false reports sometimes. It also fails to understand the context of the code. It reports that a line of code has issues without considering its relation with the previous line. The product should improve the report quality. While it asks us to improve the code quality, it would be good if it also suggests how to improve the quality.

Quotes from Members

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

Pros

"The most valuable feature for me is the Jenkins Plugin."

"The user interface is modern and nice to use."

"The setup is very easy. There is a lot of information in the documents which makes the install not difficult at all."

"Apart from software scanning, software composition scanning is valuable."

"The most valuable features of Checkmarx are difficult to pinpoint because of the way the functionalities and the features are intertwined, it's difficult to say which part of them I prefer most. You initiate the scan, you have a scan, you have the review set, and reporting, they all work together as one whole process. It's not like accounting software, where you have the different features, et cetera."

"The value you can get out of the speedy production may be worth the price tag."

"It has all the features we need."

"Overall, the ability to find vulnerabilities in the code is better than the tool that we were using before."

More Checkmarx One 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 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."

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

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

"I like not having to dig through false positives. Chasing down a false positive can take anywhere from five minutes for a small easy one, then something that is complicated and goes through a whole bunch of different class cases, and it can take up to 45 minutes to an hour to find out if it is a false positive or not."

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

"It's integrated into our CI, continuous integration."

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

More Klocwork pros

"Provides local scanning for developers."

"It is a very good tool for analysis despite its limitations."

"It is very good at identifying technical debt."

"The tool helps us to monitor and manage violations. It manages the bugs and security violations."

"The solution offers a very good community edition."

"Some of the most valuable features have been the latest up-to-date of the OWASP, the monitoring, the reporting, and the ease of use with the IDE plugins, in terms of integration."

"The solution has a wide variety of features and an open-source community that you are able to learn Java, JavaScript, or any other programing language."

"SonarQube is admin friendly."

More SonarQube Server (formerly SonarQube) pros

Cons

"Checkmarx needs to be more scalable for large enterprise companies."

"Updating and debugging of queries is not very convenient."

"I can't create a business case with multiple-factor authentication."

"Meta data is always needed."

"The plugins for the development environment have room for improvements such as for Android Studio and X code."

"Checkmarx could improve the REST APIs by including automation."

"They should make it more container-friendly and optimized for the CI pipeline. They should make it a little less heavy. Right now, it requires a SQL database, and the way the tool works is that it has an engine and then it has an analysis database in which it stores the information. So, it is pretty heavy from that perspective because you have to have a full SQL Server. They're working on something called Checkmarx Light, which is a slim-down version. They haven't released it yet, but that's what we need. There should be something a little more slimmed down that can just run the analysis and output the results in a format that's readable as opposed to having a full, really big, and thick deployment with a full database server."

"The product can be improved by continuing to expand the application languages and frameworks that can be scanned for vulnerabilities. This includes expanded coverage for mobile applications as well as open-source development tools."

More Checkmarx One cons

"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 hope that in each new release they add new features relating to the addition of checkers, improving their analysis engines etc."

"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."

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

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

"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."

More Klocwork cons

"We could use some team support, but since we are using the community version, it's not available."

"Monitoring is a feature that can be improved in the next version."

"Our developers have complained about the Quality Gates and the number of false positives that this product reports."

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

"SonarQube could improve its static application security testing as per the industry standard."

"An improvement is with false positives. Sometimes the tool can say there is an issue in your code but, really, you have to do things in a certain way due to external dependencies, and I think it's very hard to indicate this is the case."

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

"A little bit more emphasis on security and a bit more security scanning features would be nice."

More SonarQube Server (formerly SonarQube) cons

Pricing and Cost Advice

"It is not expensive, but sometimes, their pricing model or licensing model is not very clear. There are similar variables, such as projects or developers, and sometimes, it is a little bit confusing."

"Be cautious of the one-year subscription date. Once it expires, your price will go up."

"The average deal size was usually anywhere between $120K to $175K on an annual basis, which could be divided across 12 months."

"Most of my customers opted for a perpetual license. They prefer to pay the highest amount up front for the perpetual license and then pay for additional support annually."

"It is an expensive solution."

"It's relatively expensive."

"The number of users and coverage for languages will have an impact on the cost of the license."

"It is a good product but a little overpriced."

More Checkmarx One pricing and cost advice

"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 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."

"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."

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

"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."

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

"We are using the Developer Edition and the cost is based on the amount of code that is being processed."

"We use the tool's community edition."

"The product’s price is lower than Veracode’s price."

"We are using the open-source version, which is available free of cost."

"It's an open-source solution, with no additional costs."

"I use the full trial version of SonarQube."

"The price point on SonarQube is good."

"The developer edition is based on cost per lines of code."
