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.

Provides detailed reports that improve code maintainability while needing better coverage reports and technical support

Tenable.io Web Application Scanning provides a detailed report, identifying functions that are complex and need to be more maintainable and readable. It offers features such as generating an executive summary and detailed reports highlighting issues in specific lines of the code. However, it does not provide coverage reports in the free version, which is a limitation.

Quotes from Members

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

Pros

"There is a central Klocwork server at our headquarter in France so we connect the client directly to the server on-premises remotely."

"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."

"One can increase the number of vendors, so the solution is scalable."

"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."

"The most valuable feature of Klocwork is its reduced setup time."

"Overall I find Klocwork's features superior for our needs."

"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."

More Klocwork pros

"I think Tenable.io Web Application Scanning is the best option on the market at the moment."

"We can get detailed information about vulnerabilities."

"The most valuable feature is the reporting, which provides a good level of detail with respect to vulnerabilities."

"I would recommend Tenable.io Web Application Scanning to others."

"The most effective feature of the product is the ability to scan the entire environment."

"It has good unified web application scanning and exposure management."

"Now that the license is centralized, it's a significant feature to manipulate assets based on their functions."

"It is fully automated."

More Tenable.io Web Application Scanning pros

Cons

"I believe it should support more languages, such as Python and JavaScript."

"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."

"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."

"Customers using different static analysis tools report more issues than with Klocwork, indicating that Klocwork's engine is not as superior."

"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."

"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."

"There are too many warnings, and it requires expertise to determine the correct category for them."

"Klocwork does have a problem with true positives. It only found 30% of true positives in the Juliet test case."

More Klocwork cons

"The solution's dashboards could be improved and made more user-friendly."

"They have a general dashboard for web application scanning, but the dashboards and reporting can be improved. They probably have some features in their roadmap."

"The technical support should be improved. Currently, some attacks are detected while others are not."

"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."

"The reporting has a very limited customization capability."

"It isn't easy to manage vulnerabilities in Tenable."

"Tenable.io Web Application Scanning conducts a general scan, which wastes time. The scan needs to be specific."

"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."

Pricing and Cost Advice

"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."

"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."

"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."

"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."

"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 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."

"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."

"It follows the same licensing scheme as Tenable.io and Tenable. sc."

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

"Tenable.io Web Application Scanning is expensive for small businesses."

"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."

"The pricing is okay."
