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

"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."
"Unlike other static code analysis tools, Klocwork integrates seamlessly into desktop IDEs, build systems, continuous integration tools, and any team's natural workflow."
"It saves a lot of time when it comes to finding defects, it's basically inputted in every access we do."
"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."
"I recommend this tool as one of the best to be used for static analysis and should at least be tried."
"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."
"Technical support is quite good."
"Klocwork is a good product, but keep in mind that before building the code you have to get a report."
"The solution is stable."
"The most valuable feature is the reporting, which provides a good level of detail with respect to vulnerabilities."
"The solution's instant reports feature is the most effective for detecting threats."
"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."
"Our customers adopt this solution because of the replication testing and the vulnerability assessment it can do. It is a multi-faceted product."
"Tenable provides the end analysis results covering all the published vulnerabilities and information on the market."
"It is fully automated."
"Our primary use case for the solution is automated scanning; it doesn't require scripting knowledge or any of those suites or other tools, so it is fully automated, and we provide the credentials and URL and the tool does all scanning and will show the result per the requirement."
 

Cons

"Klocwork does have a problem with true positives. It only found 30% of true positives in the Juliet test case."
"There are many things that can be improved. The code used between projects is one of the very painful points in Klocwork."
"Every update that we receive requires of us a lengthy and involved process."
"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."
"This solution could be improved if they offered support of more languages including Ada and Golang. They currently only support seven languages."
"I hope that in each new release they add new features relating to the addition of checkers, improving their analysis engines etc."
"There are some false warnings found which eventually are not considered for a fix after the team reviewed the source code."
"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."
"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."
"Tenable.io Web Application Scanning conducts a general scan, which wastes time. The scan needs to be specific."
"It isn't easy to manage vulnerabilities in Tenable."
"The reporting in Tenable.io Web Application Scanning is not as good as the reporting in Tenable SC."
"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."
"I would like for them to add proxy filtering, where you can transfer and alter the package. It is fully automated. Other web application testers programs are actually proxy software, and the proxy software gives you the flexibility of modifying the outgoing package, which will actually help you in exploiting any vulnerability in detail."
"The dashboard could be more user-friendly."
"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."
 

Pricing and Cost Advice

"Klocwork should not to be quite so heavy handed on the licensing for very specific programs."
"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 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."
"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."
"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."
"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."
"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."
"The pricing is okay."
"I rate the product's pricing a four out of ten."
"Tenable.io Web Application Scanning is expensive for small businesses."
"It follows the same licensing scheme as Tenable.io and Tenable. sc."
"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."
"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."
