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

"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."

"Provides clear information and is easy to follow with good feedback regarding code practices."

"Snyk allows for scaling across large organizations, accommodating tens of thousands of applications and over 60,000 repositories, making it suitable for wide-scale deployment."

"The advantage of Snyk is that Snyk automatically creates a pull request for all the findings that match or are classified according to the policy that we create. So, once we review the PR within Snyk and we approve the PR, Snyk auto-fixes the issue, which is quite interesting and which isn't there in any other product out there. So, Snyk is a step ahead in this particular area."

"It has improved our vulnerability rating and reduced our vulnerabilities through the tool during the time that we've had it. It's definitely made us more aware, as we have removed scoping for existing vulnerabilities and platforms since we rolled it out up until now."

"I think all the standard features are quite useful when it comes to software component scanning, but I also like the new features they're coming out with, such as container scanning, secrets scanning, and static analysis with SAST."

"We use Snyk to check vulnerabilities and rectify potential leaks in GitHub."

"It is one of the best product out there to help developers find and fix vulnerabilities quickly. When we talk about the third-party software vulnerability piece and potentially security issues, it takes the load off the user or developer. They even provide automitigation strategies and an auto-fix feature, which seem to have been adopted pretty well."

"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."

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."

"Snyk's API and UI features could work better in terms of speed."

"Generating reports and visibility through reports are definitely things they can do better."

"The tool should provide more flexibility and guidance to help us fix the top vulnerabilities before we go into production."

"We have to integrate with their database, which means we need to send our entire code to them to scan, and they send us the report. A company working in the financial domain usually won't like to share its code or any information outside its network with any third-party provider."

"The solution's reporting and storage could be improved."

"I think Snyk should add more of a vulnerability protection feature in the tool since it is an area where it lacks."

"They need to improve the Snyk plugins and make it easier to make your optimizations based on your own needs or features."

"A feature we would like to see is the ability to archive and store historical data, without actually deleting it. It's a problem because it throws my numbers off. When I'm looking at the dashboard's current vulnerabilities, it's not accurate."

Pricing and Cost Advice

"Licensing is a bit expensive."

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

"Despite Snyk's coverage, scalability, reliability, and stability, it is available at a very competitive price."

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

"I would rate the pricing of Snyk at two. I'm currently using the free version, which the company offers before buying the full version. So, the price is affordable, especially for an enterprise."

"We do have some missing licenses issues, especially with non-SPDX compliant one, but we expect this to be fixed soon"

"Snyk is a premium-priced product, so it's kind of expensive. The big con that I find frustrating is when a company charges extra for single sign-on (SSO) into their SaaS app. Snyk is one of the few that I'm willing to pay that add-on charge, but generally I disqualify products that charge an extra fee to do integrated authentication to our identity provider, like Okta or some other SSO. That is a big negative. We had to pay extra for that. That little annoyance aside, it is expensive. You get a lot out of it, but you're paying for that premium."

"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."
