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

"The customer support team is very responsive, proactive, and engages in conversations to ensure our needs are met."
"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 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 best advantage of Klocwork is the reduced setup time."
"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."
"Overall I find Klocwork's features superior for our needs."
"Klocwork has caught up to Fortify and surpassed them; they have a higher detection and false positive rate than Fortify does."
"One can increase the number of vendors, so the solution is scalable."
"It does a scan that performs about 100 checks on web applications and produces a clear report on all of the vulnerabilities that are found."
"One of the most valuable features of AppSpider is its broad range of authentication identification, which is a key reason for its utilization."
"It is really accurate and the rate of false positives is very low."
"AppSpider's most valuable feature is reporting - everything is stored in the local database so it can be sent to other machines."
"Rapid7 AppSpider is good at managing different applications. It uses applets and generates reports to cover the PCA/GDPR compliance requirements."
"When it is set up properly, it can do scanning on web apps with multiple engines automatically."
"What I like most about AppSpider is that it's easy to use and its automated scan gives me all the details I need to know when it comes to vulnerabilities and their solutions."
"I would say that it is stable, as I am not aware of any major issues."
 

Cons

"Customers using different static analysis tools report more issues than with Klocwork, indicating that Klocwork's engine is not as superior."
"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."
"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."
"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 other solutions on the market such as Microsoft Visual Studio. They have been adding more static code analysis features that come for free."
"Modern languages, such as Angular and .NET, should be included as a part of Klocwork."
"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."
"This solution could be improved if they offered support of more languages including Ada and Golang. They currently only support seven languages."
"For Japanese customers, localization is needed. The product should offer a GUI in Japanese and provide Japanese reports for end-users."
"One of the challenges I have with AppSpider is that it gives you a lot of false positives, especially when compared to other solutions."
"The solution is too slow. It could take a full day to scan. Competitors are much faster."
"AppSpider could improve in the area of integration. They need to add more integration opportunities."
"Integration could be better."
"The product needs to be able to scale for large companies, like ours. We have millions of IP addresses that need to be scanned, and the scalability is not great."
"There are some glitches with stability, and it is an area for improvement."
"It needs better integration with mobile applications."
 

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."
"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 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."
"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."
"Licensing fees are paid annually, but they also have a perpetual license."
"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."
"The price is pretty fair."
"AppSpider is closed-source software and you need to acquire a license in order to use it."
"The price of Rapid7 AppSpider cost 9,000 annually but there is limited usage. Large companies are able to negotiate a better price or a better deal for the usage with the vendor."
"The licensing cost depends on the number of users."
"It is expensive if you want to buy the Enterprise version that is able to scan multiple applications at once."
