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 difficult to pinpoint because of the way the functionalities and the features are intertwined, it's difficult to say which part of them I prefer most. You initiate the scan, you have a scan, you have the review set, and reporting, they all work together as one whole process. It's not like accounting software, where you have the different features, et cetera."

"The most valuable feature for me is the Jenkins Plugin."

"Scan reviews can occur during the development lifecycle."

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

"Apart from software scanning, software composition scanning is valuable."

"It has all the features we need."

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

"It is a stable product."

More Checkmarx One pros

"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."

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

Cons

"We have received some feedback from our customers who are receiving a large number of false positives."

"The pricing can get a bit expensive, depending on the company's size."

"I would like the product to include more debugging and developed tools. It needs to also add enhancements on the coding side."

"With Checkmarx, normally you need to use one tool for quality and you need to use another tool for security. I understand that Checkmarx is not in the parity space because it's totally different, but they could include some free features or recommendations too."

"One area for improvement in Checkmarx is pricing, as it's more expensive than other products."

"The resolutions should also be provided. For example, if the user faces any problem regarding an installation due to the internal security policies of their company, there should be a resolution offered."

"If it is a very large code base then we have a problem where we cannot scan it."

"Creating and editing custom rules in Checkmarx is difficult because the license for the editor comes at an additional cost, and there is a steep learning curve."

More Checkmarx One cons

"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."

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

"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 the right price for quality delivery."

"I believe pricing is better compared to other commercial tools."

"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)."

"It is an expensive solution."

"It's relatively expensive."

"The solution's price is high and you pay based on the number of users."

"The pricing was not very good. This is just a framework which shouldn’t cost so much."

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