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.

Improves security posture by actively reducing critical vulnerabilities and guiding remediation

Snyk's main features include open-source vulnerability scanning, code security, container security, infrastructure as code security, risk-based prioritization, development-first integration, continuous monitoring and alerting, automation, and remediation. The best features I appreciate are the vulnerability checking, vulnerability scanning, and code security capabilities, as Snyk scans all open-source dependencies for known vulnerabilities and helps with license compliance for open-source components. Snyk integrates into IDEs, allowing issues to be caught as they appear in the code dynamically and prioritizes risk while providing remediation advice. Snyk provides actionable remediation advice on where vulnerabilities can exist and where code security is compromised, automatically scanning everything and providing timely alerts. Snyk has positively impacted my organization by improving the security posture across all software repositories, resulting in fewer critical vulnerabilities, more confidence in overall product security, and faster security compliance for project clients. Snyk has helped reduce vulnerabilities significantly. Initially, the repository had 17 to 31 critical and high vulnerabilities, but Snyk has helped manage them down to just five vulnerabilities, which are now lower and not high or critical.

Quotes from Members

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

Pros

"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."

"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."

"The code scans on the source code itself were valuable."

"Snyk has positively impacted my organization by improving the security posture across all software repositories, resulting in fewer critical vulnerabilities, more confidence in overall product security, and faster security compliance for project clients."

"The CLI feature is quite useful because it gives us a lot of flexibility in what we want to do. If you use the UI, all the information is there and you can see what Snyk is showing you, but there is nothing else that you can change. However, when you use the CLI, then you can use commands and can get the output or response back from Snyk. You can also take advantage of that output in a different way. For the same reason, we have been using the CLI for the hard gate in the pipeline: Obtain a particular CDSS score for vulnerability. Based on that information, we can then decide if we want to block or allow the build. We have more flexibility if we use the CLI."

"They evolved their maturity because they could find the vulnerabilities before the pipeline runs."

"The most important feature of Snyk is its cost-effectiveness compared to other solutions such as Check Point."

"There are many valuable features. For example, the way the scanning feature works. The integration is cool because I can integrate it and I don't need to wait until the CACD, I can plug it in to our local ID, and there I can do the scanning. That is the part I like best."

"Snyk helps me pinpoint security errors in my code."

"The most valuable feature of Snyk is the SBOM."

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."

"The feature for automatic fixing of security breaches could be improved."

"We tried to integrate it into our software development environment but it went really badly. It took a lot of time and prevented the developers from using the IDE. Eventually, we didn't use it in the development area... I would like to see better integrations to help the developers get along better with the tool. And the plugin for the IDE is not so good. This is something we would like to have..."

"Compatibility with other products would be great."

"The solution could improve the reports. They have been working on improving the reports but more work could be done."

"Technically, we have better vulnerabilities detection in Checkmarx and Veracode. Both of them are more precise about vulnerabilities detection."

"Although Snyk is strong, sometimes it flags vulnerabilities that are not reachable, not exploitable, and not relevant to a project."

"It can be improved from the reporting perspective and scanning perspective. They can also improve it on the UI front."

"Scalability has some issues because we have a lot of code and its use is mandatory. Therefore, it can be slow at times, especially because there are a lot of projects and reporting. Some UI improvements could help with this."

Pricing and Cost Advice

"Licensing is a bit expensive."

"The product has good pricing."

"I didn't think the price was that great, but it wasn't that bad, either. I'd rate their pricing as average in the market."

"Compared to Veracode, Snyk is definitely a cheaper tool."

"With Snyk, you get what you pay for. It is not a cheap solution, but you get a comprehensiveness and level of coverage that is very good. The dollars in the security budget only go so far. If I can maximize my value and be able to have some funds left over for other initiatives, I want to do that. That is what drives me to continue to say, "What's out there in the market? Snyk's expensive, but it's good. Is there something as good, but more affordable?" Ultimately, I find we could go cheaper, but we would lose the completeness of vision or scope. I am not willing to do that because Snyk does provide a pretty important benefit for us."

"It's inexpensive and easy to license. It comes in standard package sizing, which is straightforward. This information is publicly found on their website."

"The product's price is okay."

"The price of the solution is expensive compared to other solutions."

"The price is good. Snyk had a good price compared to the competition, who had higher pricing than them. Also, their licensing and billing are clear."
