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.
Harshal Deshmukh - PeerSpot reviewer
Simple tool to use, good dashboard capabilities and offers asset criticality ratings
It has good dashboard capabilities and gives good results with priority ratings, asset criticality ratings, and exposure scores for vulnerabilities. It also provides automated web application scanning, which customers appreciate because it doesn't disturb the web application or hamper the business. While testing the web application, sometimes it happens that the website or application goes down. But with Tenable.io Web Application Scanning, it doesn't affect the business. It has good unified web application scanning and exposure management.

Quotes from Members

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

Pros

"One can increase the number of vendors, so the solution is scalable."
"The most valuable feature of Klocwork is its reduced setup time."
"On-the-fly analysis and incremental analysis are the best parts of Klocwork. Currently, we are using both of these features very effectively."
"Klocwork is user-friendly, with a client-server architecture that provides all needed compliance."
"The tool helps the team to think beforehand about corner cases or potential bugs that might arise in real-time."
"Technical support is quite good."
"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."
"We like using the static analysis and code refactoring, which are very valuable because of our requirements to meet safety critical levels and reliability."
"Our customers adopt this solution because of the replication testing and the vulnerability assessment it can do. It is a multi-faceted product."
"Tenable.io Web Application Scanning is very easy to use."
"The most valuable feature is the reporting, which provides a good level of detail with respect to vulnerabilities."
"Tenable.io Web Application Scanning provides a detailed report, identifying functions that are complex and need to be more maintainable and readable."
"I would recommend Tenable.io Web Application Scanning to others."
"The solution's instant reports feature is the most effective for detecting threats."
"The solution is stable."
"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."
 

Cons

"I hope that in each new release they add new features relating to the addition of checkers, improving their analysis engines etc."
"Every update that we receive requires of us a lengthy and involved process."
"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."
"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."
"We'd like to see integration with Agile DevOps and Agile methodologies."
"There are too many warnings, and it requires expertise to determine the correct category for them."
"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 cloud and the on-premises versions have their own controllers, and there is no way to centrally manage controllers."
"The solution's dashboards could be improved and made more user-friendly."
"It would be great if there were a dashboard that is more user-friendly."
"The technical support needs improvement. Currently, it takes time, which might be due to the free version, but providing some level of support could encourage future purchase decisions."
"The report customization needs to be better."
"The market is standard for vulnerability scanning, however, the posture can be improved through Tenable's prioritization engine."
"The platform's technical support services could be better."
"Tenable.io Web Application Scanning is not very user-friendly and you need a lot of information to get proper reports. The tool's support is not very responsive."
 

Pricing and Cost Advice

"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."
"This solution offers competitive pricing."
"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."
"Licensing fees are paid annually, but they also have a perpetual license."
"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."
"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."
"Tenable.io Web Application Scanning is expensive for small businesses."
"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."
"It follows the same licensing scheme as Tenable.io and Tenable. sc."
"The pricing is okay."
"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."
"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."
