Klocwork Reviews

We are using the latest version.

We use the solution for regular code scanning for C and C++, as well as for MISRA rules

When an upgrade is carried out it must be done on both the server and client side, which can make it a bit hectic for all projects to be configured on the private server. Every update that we receive requires of us a lengthy and involved process.

The project reporting status dashboard should also be addressed. As I am on the compliance team, I must open every project to resolve all issues.  The solution does not provide consolidated views. Meanwhile, Kuiwan has a very good feature on its dashboard.

Moreover, Klocwork makes a limited number of languages available to the user, only four. In addition, a good consolidated dashboard, in respect of compliance, would be nice to see.

I have been working with Klocwork for seven or eight years.

Technical support is quite good. We have a vendor partner in India and they do a good job of supporting us. 

Klocwork was easy to install. But, as we are using an on-premises server, our client's configuration needs are different. Since this is on the user's machine the installation part is easy. Yet, the receipt of frequent updates means that time which could be spent on the project side is consumed by that of development.

When it comes to licensing, the solution has two packages, one for a fixed and the other for a floating server. The former is more cost effective than the latter. 

We are currently using SonarQube for other languages, those of Python and Android.

At present, we make use of both the Klocwork and SonarQube tools. However, as we wish to have a combined tool, we are planning to switch to Kuiwan.

I rate Klocwork as a seven out of 10. 

Our primary use case of Klocwork is for static project analysis and for getting ratios.

I really like Klocwork's server client build because it allows collaboration between the team members. It takes the ratios and it has a portal where one can justify the issues.

There are many things that can be improved. The code used between projects is one of the very painful points in Klocwork. So if you are using a code and the product is shared between projects, you have to analyze the different projects just to comment if it is good or to justify it in the different projects. And the solutions they provide for the issues, are not fully correct. So this is the main issue is using the code between projects.

I have been using Klocwork for around four months now.

I think the solution is fairly stable. We've had some issues in the GUI, and even in the server portal and in the server application. We've also had issues with an outside application that is  also a GUI client. So I will say it is stable but there are some issues.

One can increase the number of vendors, so the solution is scalable. We currently have around 3,000 users.

We don't deal with the technical team directly, because we have a service line. So if I have an issue, we report to our service line and they report to the technical support team.

The initial setup wasn't complex - it was really straightforward.

My advice to others would be that they should determine their use case before buying the program. If they have many codes, I would not recommend it. If they have a separate project where not many codes are shared between projects, I will recommend it. 

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

On a scale from one to 10, I rate this product a seven.

We are involved in implementing the applying and supporting Klocwork for various customers as we are a Klokwork partner. Klocwork is an advanced static code analysis tool also used to detect all possible vulnerabilities that are present in the source code.

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. This means that you don't have to wait for the development to finish and waste that time. This provides efficiency. 

Klocwork also has various plugins available for development tools and they work seamlessly. Our clients often opt for Klocwork due to its accuracy of results and the continuous addition of new features. 

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

In a future release, we would like to have architecture management added.

We have been using this solution for ten years.

This is a stable solution and is a specific feature that this solution is well known for. 

This is a scalable solution and can be deployed to suit any requirement of a customer. We have customers using 1,200 Klocwork licenses, which is served through only one license server.

The customer support team are responsive and provide support via email and phone. 

I would rate them a five out of five. 

Positive

The initial setup is straightforward. We can complete the entire deployment in less than 30 minutes and it does not involve any manual configuration. It is fully automated. I have completed more than 100 deployments and have not faced any issues. 

Once Klocwork is installed and configured as part of your automation pattern, there is no maintenance required. 

This solution offers competitive pricing. 

Klocwork does data flow analysis and is proven to be more accurate. It also supports many industry standards like MISRA, OWASP, CERT and AUTOSAR which many other tools do not. It can also be used to deliver internal coding guidelines. 

I would rate this solution a nine out of ten. 

Klocwork is part of our automated system, continuously improving the pipeline. Whenever the software is merged into the project control system, it is going to reduce Klocwork scanning automatically.

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.

Klocwork has to improve its features to stay ahead of other free or low-cost solutions, like Visual Studio Code Analyzer.

I have used Klocwork within the last 12 months.

Klocwork is a stable solution but the performance could improve when compared to other solutions.

I have used the support from Klocwork. There was a transition time when we started using the solution which was not smooth. However, we didn't need to report any problems after that.

I have previously used Apple Xcode and Microsoft Visual Studio static code analysis and then JetBrains ReSharper type of the code analysis from the third-party tool, which is much cheaper than the Klocwork. Additionally, they are faster. I do not think we will be using Klocwork for much longer.

Klocwork was straightforward to implement and took us a half-day to implement and the upgrade took less time.

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 is an expensive solution.

When we first purchased Klocwork I would have rated it a nine or ten out of ten. However, because of the performance of the execution and cost, I would no longer rate it that high.

I rate Klocwork a six out of ten.

• Good set of checkers for static code analysis, cyber security
• Possibility of creating custom checkers- Good and easy integration into continuous integration (CI)
• The whole package offers a lot of possibilities: add-ons for Eclipse, standalone clients, access via web site, support, documentation, command line.

More and more departments are targeting static code analysis now, as they see the benefits. Klocwork with its capabilities is helping with this, providing the integration. The advantage is that while coding, developers see code violations.

• Global variables sometimes generate false positives. Variables with global scopes sometimes produce False Positives. It means, I get violations from KW which after personal analysis turn out to be not true. At the moment it seems Klocwork is not able to track the values of variables with global scope. Thus the tool makes assumptions for the value range. It occurs that I get violations due to values which simply cannot occur > as the global variables are not tracked. This is annoying and time consuming. One simpler thing on variables with global scope: unused variables with global scope cannot be detected by checkers. This is highly recommended to have it in order to clean the code.
• The preprocessor needs better integration for custom checkers as the tool focuses more on static code analysis; after preprocessing the file.- Updating from one version to the other takes too much time. The process somehow needs too much CPU power.
• Once there are bugs detected and accepted by KW, it takes some time to integrate the changes. This means that what does not fit on the Rogue Wave road map is not definitely considered.

I have used it for four years.

I did not encounter any stability issues; only that the update process takes too long. Here, the process could be speeded up.

Scalability is good, from small teams to multisite project teams.

Technical support is good (7/10).

I previously used PC-lint. I switched because KW is more mature.

Initial setup is going well; very straightforward and following its documentation.

I evaluated QAC/QAC++, LDRA Testbed.

A good thing is that you are rapidly ramped up and can use the tool.

Klocwork is part of the DevOps process. It is scaling the code on every request.

It saves a lot of time when it comes to finding defects, it's basically inputted in every access we do.

The most valuable feature is the Incremental analysis.

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

I would like to see dynamic analysis as well.

I have been working with Klocwork for seven years.

We are using version 2021.2.

Klocwork is very stable and very mature.

It is very scalable.

In our organization, we have 50 users.

It is used on a daily basis. It's one of the most important tools that every developer has.

The support is good. We have no problems with the support.

We used Coverity in the past, but they shifted their focus, and we switched to Klocwork.

The initial setup is straightforward.

It is simple to set up and can be done by any developer.

The initial deployment took a couple of days.

We have one person, working half-time to maintain this solution. That is all that is needed.

I didn't require any assistance because I installed it myself.

We have seen a return on investment. Each developer invests at least half an hour a day less on defects. 

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

There are no additional costs.

I would recommend, first creating a baseline of their source code with all of the issues, and then handling the new issues on a daily basis while gradually resolving the old ones.

I would rate Klocwork a nine out of ten.

It is one of the best tools available for static analysis.

This tool was already rolled out in our projects at Delphi Technical Center in Bangalore, India. Though we had a QAC tool for MISRA checks, Klocwork was preferred for complete code base static analysis before projects go to production.

For all GM projects, this tool is used to perform static analysis. It provides a nice report, so all manual efforts in analyzing the code base are completely removed.

There are some false warnings found which eventually are not considered for a fix after the team reviewed the source code.

We have been using the system for around three years.

It is quite stable, reliable and has not shown any difference in the results for multiple runs.

We have not tried to scale yet, but it was sufficient for our current projects.

We have not encountered any problems at my level. I have no idea how the technical support is.

We were using QAC and Klocwork at my previous company. At my current organization, we use Polyspace.

The setup was in place when I arrived.

I have no idea about pricing.

I was not involved in the tool evaluation process.

I recommend this tool as one of the best to be used for static analysis and should at least be tried.

our primary use case was to find and fix all possible static vulnerabilities like Buffer over flow, null pointer check, array out of bounds, concurrency violations, etc.., We work on Linux platform with gcc compiler. 

It has helped our organization to produce the non-defective code right at the developer's desktop. So we were able to deliver releases on time.

The pre-checkin code review, industry standard checks, continuous integration (CI) and customized checkers are the most valuable features.

It would be nice to consider having more language support ability. Currently Klocwork supports C/C++, Java and C#, (Android*)

Klocwork is very stable. i have seen Klocwork running on 40 million lines of code without any problem. 

Klocwork has almost all the features what an advanced Static code analyser should have. 

Customer Service:

Customer service is great. We are getting responses from support within a day. The local support (I am from India) is also good.

Technical Support:

Technical support from Klocwork is great. The Klocwork documentations are available online so we hardly contact the Klocwork support.

We were using three Open Source static analyzers and faced lots of false-positives and false-negatives. Klocwork has given us better results with real issues.

Setup was straightforward with the installation shields (a single .exe for Windows and .sh file for Linux).

For the very first time, the vendor team had helped us in the deployment. Their support was great. From the second time onwards, our internal team was able to upgrade and install with the help of online documentations.

We got what we have expected. Klocwork worth the price. 

The Klocwork tool is worth the price that they have quoted.

we have evaluated multiple open source tools and few commercial tools.

Unlike other static code analysis tools, Klocwork integrates seamlessly into desktop IDEs, build systems, continuous integration tools, and any team's natural workflow. Mirroring how code is developed at any stage, Klocwork prevents defects and finds vulnerabilities on-the-fly, as code is being written.

Klocwork also helps prioritize work with SmartRank, the revolutionary new recommendation engine that prioritizes issues and helps select which ones to work on first.

Take prioritized, corrective action immediately to deliver more secure and reliable code.
