Specialist Leader at Deloitte

Partner experiences excellent technical support and seamless initial setup

In my opinion, if we are able to extract or show the report, and because everything is going towards agent tech and GenAI, it would be beneficial if it could get integrated with our code base and do the fix automatically. It could suggest how the code base is written and automatically populate the source code with three different solution options to choose from. This would be really helpful.

Product security tests for switches and router sections

Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install. What I see in the documentation isn't that. Even if something doesn't malfunction, sometimes it is hard to install and execute. The product needs video documentation. This would help a lot more.

Quotes from Members

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

Pros

"The most valuable features of Checkmarx are the automation and information that it provides in the reports."

"Compared to the solutions we used previously, Checkmarx has reduced our workload by almost 75%."

"One of the most valuable features is it is flexible."

"It allows for SAST scanning of uncompiled code. Further, it natively integrates with all key repos formats (Git, TFS, SVN, Perforce, etc)."

"It can integrate very well with DAST solutions. So both of them are combined into an integrated solution for customers running application security."

"The setup is very easy. There is a lot of information in the documents which makes the install not difficult at all."

"Vulnerability details is valuable."

"What I like best about Checkmarx is that it has fewer false positives than other products, giving you better results."

More Checkmarx One pros

"The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."

"Whatever the test suit they give, it is intelligent. It will understand the protocol and it will generate the test cases based on the protocol: protocol, message sequence, protocol, message structure... Because of that, we can eliminate a lot of unwanted test cases, so we can execute the tests and complete them very quickly."

"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."

Cons

"As the solution becomes more complex and feature rich, it takes more time to debug and resolve problems. Feature-wise, we have no complaints, but Checkmarx becomes harder to maintain as the product becomes more complex. When I talk to support, it takes them longer to fix the problem than it used to."

"The cost per user is high and should be reduced."

"I would like to see the DAST solution in the future."

"The validation process needs to be sped up."

"It would be really helpful if the level of confidence was included, with respect to identified issues."

"The interactive application security testing, or IAST, the interactive part where you're looking at an application that lives in a runtime environment on a server or virtual machine, needs improvement."

"I can't create a business case with multiple-factor authentication."

"Some of the descriptions were found to be missing or were not as elaborate as compared to other descriptions. Although, they could be found across various standard sources but it would save a lot of time for developers, if this was fixed."

More Checkmarx One cons

"Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install."

"Sometimes, when we are testing embedded devices, when we trigger the test cases, the target will crash immediately. It is very difficult for us to identify the root cause of the crash because they do not provide sophisticated tools on the target side. They cover only the client-side application... They do not have diagnostic tools for the target side. Rather, they have them but they are very minimal and not very helpful."

"It does not support the complete protocol stack. There are some IoT protocols that are not supported and new protocols that are not supported."

Pricing and Cost Advice

"It is an expensive solution."

"Most of my customers opted for a perpetual license. They prefer to pay the highest amount up front for the perpetual license and then pay for additional support annually."

"Its price is fair. It is in or around the right spot. Ultimately, if the price is wrong, customers won't commit, but they do tend to commit. It is neither too cheap nor too expensive."

"Before implementing the product I would evaluate if it is really necessary to scan so many different languages and frameworks. If not, I think there must be a cheaper solution for scanning Java-only applications (which are 90% of our applications)."

"The number of users and coverage for languages will have an impact on the cost of the license."

"This solution is expensive. The customized package allows you to buy additional users at any time."

"We have a subscription license that is on a yearly basis, and it's a pretty competitive solution."

"The license has a vague language around P1 issues and the associated support. Make sure to review these in order to align them with your organizational policies."
