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.

Users can access the platform without worrying about hardware failures or maintenance issues that can affect on-premises solutions. Moreover, Mend.io's integration capabilities with existing workflows—including IDEs, repositories, and CI/CD pipelines—enhance its stability by providing a seamless user experience. This integration allows teams to incorporate security scanning into their development processes without significant disruptions, which is often a challenge with less stable solutions. Feedback from our developers and architects highlights the tool's effectiveness in reducing open-source software vulnerabilities while maintaining a streamlined development lifecycle. Our organization have experienced improved code quality and faster incident response times as a result of using Mend.io. The platform's intuitive dashboard and management views are also praised by our developers for their usability, contributing to a positive user experience. In short, Mend.io stands out as a dependable and reliable solution in the realm of software composition analysis. Its high stability, combined with robust integration capabilities and user-friendly features, makes it an excellent choice for organizations seeking to enhance their security posture while minimizing operational disruptions.

Quotes from Members

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

Pros

"The customer support team is very responsive, proactive, and engages in conversations to ensure our needs are met."

"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."

"Technical support is quite good."

"On-the-fly analysis and incremental analysis are the best parts of Klocwork. Currently, we are using both of these features very effectively."

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

"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."

"The best advantage of Klocwork is the reduced setup time."

"We like using the static analysis and code refactoring, which are very valuable because of our requirements to meet safety critical levels and reliability."

More Klocwork pros

"Attribution and license due diligence reports help us with aggregating the necessary data that we, in turn, have to provide to satisfy the various licenses copyright and component usage disclosures in our software."

"Mend.io is very robust in terms of managing third-party dependencies."

"The most valuable feature is the unified JAR to scan for all langs (wss-scanner jar)."

"I am the organizational deployment administrator for this tool, and I, along with other users in our company, especially the security team, appreciate the solution for several reasons. The UI is excellent, and scanning for security threats fits well into our workflow."

"For us, the most valuable tool was open-source licensing analysis."

"The results and the dashboard they provide are good."

"The reporting capability gives us the option to generate an open-source license report in a single click, which gets all copyright and license information, including dependencies."

"With the fix suggestions feature, not only do you get the specific trace back to where the vulnerability is within your code, but you also get fix suggestions."

More Mend.io pros

Cons

"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."

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

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

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

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

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

"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."

More Klocwork cons

"The initial setup could be simplified."

"We have ended our relationship with WhiteSource. We were using an agent that we built in the pipeline so that you can scan the projects during build time. But unfortunately, that agent didn't work at all. We have more than 500 projects, and it doubled or tripled the build time. For other projects, we had the failure of the builds without any known reason. It was not usable at all. We spent maybe one year working on the issues to try to make it work, but it didn't in the end. We should be able to integrate it with ID and Shift Left so that the developers are able to see the scan results without waiting for the build to fail."

"Mend lets you create custom policies. They're not too complicated to set up, but it would be helpful if they had some preconfigured policies to match what we have in Azure DevOps. That would save us a lot of time. It's tedious to configure the policies manually, and I lack the capacity to do it right now. Other products have preconfigured packs and templates, and Mend doesn't."

"It would be nice to have a better way to realize its full potential and translate it within the UI or during onboarding."

"Make the product available in a very stable way for other web browsers."

"I rated the solution an eight out of ten because WhiteSource hasn't built in a couple of features that we would have loved to use and they say they're on their roadmap. I'm hoping that they'll be able to build and deliver in 2022."

"If anything, I would spend more time making this more user-friendly, better documenting the CLI, and adding more examples to help expand the current documentation."

"The only thing that I don't find support for on Mend Prioritize is C++."

Pricing and Cost Advice

"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 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."

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

"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."

"Licensing fees are paid annually, but they also have a perpetual license."

"Pricing and licensing are comparable to other tools. When we started, it was less than our existing solution. I can't go into specifics, but it isn't cheap."

"As we were using an SaaS-based service, the solution must be scalable, although my understanding is that this is based on the licensing model one is using."

"Mend is costly but not overly expensive. The license was quite expensive this year, but we managed to negotiate the price down to the same as last year. At the same time, it's a good value. We're getting what we're paying for and still not using all the features. We could probably get more out of the tool and make it more valuable. At the moment, we don't have the capacity to do that."

"It is fairly priced."

"We are paying a lot of money to use WhiteSource. In our company, it is not easy to argue that it is worth the price. "

"Its pricing model is per developer. It depends on the number of developers in the company. The license is for a minimum of 20 developers. So, even if you are a small startup with less than 10 developers, you have to buy a license for 20 developers on a yearly subscription, which makes it quite expensive for startup customers. I provide consultation to startup accelerators. They're small at the beginning, and only once they grow to 20 developers, they can afford this tool. As a result, WhiteSource is missing this target audience. Their licensing is not flexible."

"We always negotiate for the best price possible, and as far as I know, Mend has done an excellent job with their pricing. Our management is happy with the pricing, which has led to renewals."

"Pricing is competitive."

Reviews from Real Users

Below are some reviews and helpful feedback written by PeerSpot users currently using the Mend.io solution.

Jeffrey H., System Manager of Cloud Engineering at Common Spirit, says, “Finding vulnerabilities is pretty easy. Mend.io (formerly WhiteSource) does a great job of that and we had quite a few when we first put this in place. Mend.io does a very good job of finding the open-source, checking the versions, and making sure they're secure. They notify us of critical high, medium, and low impacts, and if anything is wrong. We find the product very easy to use and we use it as a core part of our strategy for scanning product code moving toward release.”

PeerSpot reviewer Ben D., Head of Software Engineering at a legal firm, mentions, “The way WhiteSource scans the code is great. It’s easy to identify and remediate open source vulnerabilities using this solution. WhiteSource helped reduce our mean time to resolution since we adopted the product. In terms of integration, it's pretty easy.”

An IT Service Manager at a wholesaler/distributor comments, “Mend.io provides threat detection and an excellent UI in a highly stable solution, with outstanding technical support.”

Another reviewer, Kevin D., Intramural OfficialIntramural at Northeastern University, states, "The vulnerability analysis is the best aspect of the solution."
