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

"Klocwork is a good product, but keep in mind that before building the code you have to get a report."
"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."
"Klocwork has caught up to Fortify and surpassed them; they have a higher detection and false positive rate than Fortify does."
"Klocwork is user-friendly, with a client-server architecture that provides all needed compliance."
"The most valuable feature of Klocwork is its reduced setup time."
"Unlike other static code analysis tools, Klocwork integrates seamlessly into desktop IDEs, build systems, continuous integration tools, and any team's natural workflow."
"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."
"Klocwork has reduced the manual analysis for a lot of scenarios like checking for internal standards and has saved a lot of time in developing code through the on the fly analysis mode."
"It is fully automated."
"Now that the license is centralized, it's a significant feature to manipulate assets based on their functions."
"The most valuable features of Tenable.io Web Application Scanning are the integration into specific use cases and scanning. All of the features of the solution are useful."
"The product provides comprehensive details and reports to help us understand everything and handle any patches in order to keep our system safe."
"It collects the vulnerabilities on the hostnames and sends them to the Tenable.io cloud. Tenable has its own cloud where Tenable.io is running, but there are many connectors to other cloud solutions. Tenable can do vulnerability scanning for other cloud managers such as Azure, Amazon, and so on."
"The initial setup is straightforward."
"I would recommend Tenable.io Web Application Scanning to others."
"The most valuable feature is the reporting, which provides a good level of detail with respect to vulnerabilities."
 

Cons

"Even though it does the job, there's room for feature enhancements, such as integrations with Git for better tracking and notifications."
"Klocwork does have a problem with true positives. It only found 30% of true positives in the Juliet test case."
"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."
"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."
"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."
"Klocwork sometimes provides too many additional warnings which require expertise to manage."
"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."
"Every update that we receive requires of us a lengthy and involved process."
"Sometimes it lags with different cloud environments."
"The solution's dashboards could be improved and made more user-friendly."
"The dashboard could be more user-friendly."
"The market is standard for vulnerability scanning, however, the posture can be improved through Tenable's prioritization engine."
"The technical support should be improved. Currently, some attacks are detected while others are not."
"The report customization needs to be better."
"Tenable.io Web Application Scanning conducts a general scan, which wastes time. The scan needs to be specific."
"The reporting in Tenable.io Web Application Scanning is not as good as the reporting in Tenable SC."
 

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."
"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."
"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."
"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."
"I rate the product's pricing a four out of ten."
"The pricing is okay."
"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."
"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."
