We're gathering vulnerability data from multiple environments in real time, fundamentally changing how we identify issues in applications

The solution is very accurate in identifying vulnerabilities. In cases where we are performing application assessment using Contrast Assess, and also using legacy application security testing tools, Contrast successfully identifies the same vulnerabilities that the other tools have identified but it also identifies significantly more. In addition, it has visibility into application components that other testing methodologies are unaware of. Assess also provides the option of helping developers incorporate security elements while they're writing code. It depends on whether individual developers decide to utilize the information that's provided to them from the solution, but it definitely gives them visibility into more environments. It gives them an opportunity to remediate vulnerabilities well before production deployments.

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.

Quotes from Members

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

Pros

"This has changed the way that developers are looking at usage of third-party libraries, upfront. It's changing our model of development and our culture of development to ensure that there is more thought being put into the usage of third-party libraries."

"Assess has an excellent API interface to pull APIs."

"The most valuable feature is the continuous monitoring aspect: the fact that we don't have to wait for scans to complete for the tool to identify vulnerabilities. They're automatically identified through developers' business-as-usual processes."

"We use the Contrast OSS feature that allows us to look at third-party, open-source software libraries, because it has a cool interface where you can look at all the different libraries. It has some really cool additional features where it gives us how many instances in which something has been used... It tells us it has been used 10 times out of 20 workloads, for example. Then we know for sure that OSS is being used."

"In our most critical applications, we have a deep dive in the code evaluation, which was something we usually did with periodic vulnerability assessments, code reviews, etc. Now, we have real time access to it. It's something that has greatly enhanced our code's quality. We have actually embedded a KPI in regards to the improvement of our code shell. For example, Contrast provides a baseline where libraries and the usability of the code are evaluated, and they produce a score. We always aim to improve that score. On a quarterly basis, we have added this to our KPIs."

"When we access the application, it continuously monitors and detects vulnerabilities."

"The accuracy of the solution in identifying vulnerabilities is better than any other product we've used, far and away. In our internal comparisons among different tools, Contrast consistently finds more impactful vulnerabilities, and also identifies vulnerabilities that are nearly guaranteed to be there, meaning that the chance of false positives is very low."

"It is a stable solution...Contrast Security Assess is one of the first players in this market, so they have experience and customers, especially abroad. Overall, it's a good product."

More Contrast Security Assess pros

"The ability to create custom checkers is a plus."

"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."

"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."

"The most valuable feature is the Incremental analysis."

"It's integrated into our CI, continuous integration."

More Klocwork pros

Cons

"I would like to see them come up with more scanning rules."

"Contrast Security Assess covers a wide range of applications like .NET Framework, Java, PSP, Node.js, etc. But there are some like Ubuntu and the .NET Core which are not covered. They have it in their roadmap to have these agents. If they have that, we will have complete coverage."

"I think there was activity underway to support the centralized configuration control. There are ways to do it, but I think they were productizing more of that."

"Personalization of the board and how to make it appealing to an organization is something that could be done on their end. The reports could be adaptable to the customer's preferences."

"The out-of-the-box reporting could be improved. We need to write our own APIs to make the reporting more robust."

"The setup of the solution is different for each application. That's the one thing that has been a challenge for us. The deployment itself is simple, but it's tough to automate because each application is different, so each installation process for Contrast is different."

"The solution should provide more details in the section where it shows that third-party libraries have CVEs or some vulnerabilities."

"To instrument an agent, it has to be running on a type of application technology that the agent recognizes and understands. It's excellent when it works. If we're using an application that is using an unsupported technology, then we can't instrument it at all. We do use PHP and Contrast presently doesn't support that, although it's on their roadmap. My primary hurdle is that it doesn't support all of the technologies that we use."

More Contrast Security Assess cons

"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."

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

"This solution could be improved if they offered support of more languages including Ada and Golang. They currently only support seven languages."

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

"Global variables sometimes generate false positives. Variables with global scopes sometimes produce false positives, which is annoying and time consuming because I get violations from Klocwork which after personal analysis turn out to be not true."

"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."

"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."

More Klocwork cons

Pricing and Cost Advice

"I like the per-application licensing model... We just license the app and we look at different vulnerabilities on that app and we remediate within the app. It's simpler."

"The solution is expensive."

"It's a tiered licensing model. The more you buy, as you cross certain quantity thresholds, the pricing changes. If you have a smaller environment, your licensing costs are going to be different than a larger environment... The licensing is primarily per application. An application can be as many agents as you need. If you've got 10 development servers and 20 production servers and 50 QA servers, all of those agents can be reporting as a single application that utilizes one license."

"You only get one license for an application. Ours are very big, monolithic applications with millions of lines of code. We were able to apply one license to one monolithic application, which is great. We are happy with the licensing. Pricing-wise, they are industry-standard, which is fine."

"For what it offers, it's a very reasonable cost. The way that it is priced is extremely straightforward. It works on the number of applications that you use, and you license a server. It is something that is extremely fair, because it doesn't take into consideration the number of requests, etc. It is only priced based on the number of onboarded applications. It suits our model as well, because we have huge traffic. Our number of applications is not that large, so the pricing works great for us."

"The good news is that the agent itself comes in two different forms: the unlicensed form and the licensed form. Unlicensed gives use of that software composition analysis for free. Thereafter, if you apply a license to that same agent, that's when the instrumentation takes hold. So one of my suggestions is to do what we're doing: Deploy the agent to as many applications as possible, with just the SCA feature turned on with no license applied, and then you can be more choosy and pick which teams will get the license applied."

"The product's pricing is low. I would rate it a two out of ten."

"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."

"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."

"This solution offers competitive pricing."

"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."

"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."

"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."
