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.

Centralized security monitoring has reduced false positives and improves dependency governance
The only area for improvement I would say is that the false positives are nearly zero; everything is mostly like 99 to 99.99% or we can say 100% accurate. There were a few areas for improvement just from the last time I saw; I think the user experience had a little problem. We wanted to have certain reports based on our kind of scenario, but the tool did not allow us to create custom reports. We had asked for some facility and some ability for us to create some custom reports. That would be awesome if they allow us to create custom reports the way we wanted. There is one small area which I don't know whether we should call a tool limitation or a wish list; if I use a library and I don't use all the capabilities of the library but only a portion of it and that portion is not vulnerable, but there is a component which is outdated, that is a problem, even though I don't use that component. Mend.io will discover there is a problem in the whole library; that is correct. That's a valid discovery, but in my case, for example, if I don't use that particular portion, then it actually is not making sense for me, but that's not a limitation of Mend.io; I think that's a general problem with any tool in the market because no tool in the market will actually know what portion of the code I'm actually using from that particular library if it is vulnerable or not.

Quotes from Members

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

Pros

"Simple and straightforward GUI."
"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, and because of that, we can eliminate a lot of unwanted test cases so we can execute the tests and complete them very quickly."
"ROI was 100%. Since there are no product suites available that provide the level of testing available with Codenomicon, the development, quality and security assurance departments know that the investment was correct."
"The stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
"The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."
"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."
"The vulnerability analysis is the best aspect of the solution."
"Scanning and collecting third-party libraries and classifying license types ensures our third-party software policy is followed and that we’re not using forbidden libraries."
"WhiteSource is unique in the scanning of open-source licenses. Additionally, the vulnerabilities aspect of the solution is a benefit. We don't use WhiteSource in the whole organization, but we use it for some projects. There we receive a sense of the vulnerabilities of the open-source components, which improves our security work. The reports are automated which is useful."
"WhiteSource is very easy to run and use, and it reduced significantly the time our developers used to spend on issues in open-source libraries."
"Our primary goal was to get the license reports, but now we have a full end-to-end process that automates all license management, open-source license approval, rejection, ticket assignment, and more."
"We use a lot of open sources with a variety of containers, and the different open sources come with different licenses. Some come with dual licenses, some are risky and some are not. All our three use cases are equally important to us and we found WhiteSource handles them decently."
"The solution boasts a broad range of features and covers much of what an ideal SCA tool should."
"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."
 

Cons

"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."
"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 requires understanding the Defensics protocol."
"You can't implement proprietary ciphering algorithms, nor can you modify protocol models if you need to test customized public protocols."
"AI integration in code security tools like Mend.io is still in its early stages and relatively immature."
"Make the product available in a very stable way for other web browsers."
"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."
"It would be nice to have a better way to realize its full potential and translate it within the UI or during onboarding."
"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."
"WhiteSource is working on a UI refresh. That's probably been one of the pain points for us as it feels like a really old application."
"I would like to see the static analysis included with the open-source version."
"I would like to have an additional compliance pack. Currently, it does not have anything for the CIS framework or the NIST framework. If we directly run a scan, and it is under the CIS framework, we can directly tell the auditor that this product is now CIS compliant."
 

Pricing and Cost Advice

"Licensing is a bit expensive."
"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."
"WhiteSource is much more affordable than Veracode."
"This is an expensive solution."
"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."
"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."
"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. ​"
"Pricing is competitive."
"Over the last two years, they have tried to add more and more features to their license packages, but the price is a little bit high, comparatively."
