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.

Centralized license management transforms asset manipulation based on functions and improves security posture

Now that the license is centralized, it's a significant feature to manipulate assets based on their functions. It provides a centralized view from end-to-end to its assets' identities and vulnerabilities. One of the greatest features is Kubernetes. The automated scanning capability is pretty standard in the market, and Tenable's prioritization engine helps improve the security posture.

Quotes from Members

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

Pros

"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."

"Technical support is quite good."

"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."

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

"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 most valuable feature is the Incremental analysis."

"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."

More Klocwork pros

"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."

"Tenable.io Web Application Scanning provides a detailed report, identifying functions that are complex and need to be more maintainable and readable."

"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."

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

"The initial setup is straightforward."

"It is fully automated."

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

More Tenable.io Web Application Scanning pros

Cons

"I would like to see better codes between projects and a more user-friendly desktop in the next release."

"Klocwork has to improve its features to stay ahead of other free solutions."

"Even though it does the job, there's room for feature enhancements, such as integrations with Git for better tracking and notifications."

"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."

"Every update that we receive requires of us a lengthy and involved process."

"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."

"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."

More Klocwork cons

"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 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 market is standard for vulnerability scanning, however, the posture can be improved through Tenable's prioritization engine."

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

"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 report customization needs to be better."

"Sometimes it lags with different cloud environments."

"Tenable.io Web Application Scanning could improve by offering faster fuzzing."

More Tenable.io Web Application Scanning cons

Pricing and Cost Advice

"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."

"Klocwork should not to be quite so heavy handed on the licensing for very specific programs."

"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."

"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."

"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."

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

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

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

"The pricing is okay."
