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.

Web audits have identified vulnerabilities and now provide clear visibility into compliance gaps
We have experience with Tenable.io Web Application Scanning, and we use it as well; we have approximately ten licenses for web application scanning. We use it to find vulnerabilities, but Tenable.io Web Application Scanning does not include remediation; we remediate with other products. We use the…

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 of Klocwork is finding defects while you're doing the coding, similar to using spell check on Word, so you can find out defects during the development phase and you don't have to wait until the development is over to find the flaws and address the deficiencies."
"Klocwork's most valuable feature is the static code analysis feature. It detects the potential problem earlier to allow the developer to receive feedback quickly and then address it before it becomes a problem."
"I really like Klocwork's server client build because it allows collaboration between the team members."
"The most valuable feature of Klocwork is its reduced setup time."
"It saves a lot of time when it comes to finding defects, it's basically inputted in every access we do."
"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 tool helps the team to think beforehand about corner cases or potential bugs that might arise in real-time."
"The most valuable feature of Klocwork is its reduced setup time."
"Our customers adopt this solution because of the replication testing and the vulnerability assessment it can do. It is a multi-faceted product."
"The most effective feature of the product is the ability to scan the entire environment."
"Tenable.io Web Application Scanning provides a detailed report, identifying functions that are complex and need to be more maintainable and readable."
"The initial setup is straightforward."
"If customers need a cost-efficient way to do very good ramification scanning and vulnerability management, this is the right solution."
"Tenable.io Web Application Scanning is very easy to use."
"Tenable provides the end analysis results covering all the published vulnerabilities and information on the market."
"I would recommend Tenable.io Web Application Scanning to others."
 

Cons

"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."
"Klocwork sometimes provides too many additional warnings which require expertise to manage."
"There are too many warnings, and it requires expertise to determine the correct category for them."
"Even though it does the job, there's room for feature enhancements, such as integrations with Git for better tracking and notifications."
"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."
"I believe it should support more languages, such as Python and JavaScript."
"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."
"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."
"It would be great if there were a dashboard that is more user-friendly."
"The technical support should be improved. Currently, some attacks are detected while others are not."
"It isn't easy to manage vulnerabilities in Tenable."
"The cloud and the on-premises versions have their own controllers, and there is no way to centrally manage controllers."
"The reporting in Tenable.io Web Application Scanning is not as good as the reporting in Tenable SC."
"The platform's technical support services could be better."
"We have encountered some problems with the technical support from Tenable; I would rate it a five out of ten. It is not efficacious, especially the first-level support."
"The report customization needs to be better."
 

Pricing and Cost Advice

"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."
"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."
"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 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."
"Klocwork should not to be quite so heavy handed on the licensing for very specific programs."
"The pricing is okay."
"It follows the same licensing scheme as Tenable.io and Tenable. sc."
"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."
"The price of the solution is reasonable compared to the competitors. The license cost is based on the number of users and the annual usage."
"I rate the product's pricing a four out of ten."
"The application is extremely affordable. There are no additional costs involved with licensing. We switched to Tenable.io Web Application Scanning from other solutions due to pricing."
"Tenable.io Web Application Scanning is expensive for small businesses."
