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

"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."

"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 most valuable feature of Snyk is the software composition analysis."

"It is a stable solution. Stability-wise, I rate the solution a ten out of ten."

"What is valuable about Snyk is its simplicity."

"Snyk provides a lot of information on vulnerabilities, the packages being used, and their dependencies, giving good insight into the security of those packages."

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

"It's very easy for developers to use. Onboarding was an easy process for all of the developers within the company. After a quick, half-an-hour to an hour session, they were fully using it on their own. It's very straightforward. Usability is definitely a 10 out of 10."

"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."

"The best feature of Snyk is the integration with our ticketing system, which is Jira."

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."

"Basically the licensing costs are a little bit expensive."

"We would like to have upfront knowledge on how easy it should be to just pull in an upgraded dependency, e.g., even introduce full automation for dependencies supposed to have no impact on the business side of things. Therefore, we would like some output when you get the report with the dependencies. We want to get additional information on the expected impact of the business code that is using the dependency with the newer version. This probably won't be easy to add, but it would be helpful."

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

"There are a lot of false positives that need to be identified and separated."

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

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

"I use Snyk alongside Sonar, and Snyk tends to generate a lot of false positives. Improving the overall report quality and reducing false positives would be beneficial. I don't need additional features; just improving the existing ones would be enough."

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

Pricing and Cost Advice

"Licensing is a bit expensive."

"The license model is based on the number of contributing developers. Snyk is expensive, for a startup company will most likely use the community edition, while larger companies will buy the licensed version. The price of Snyk is more than other SLA tools."

"We are using the open-source version for the scans."

"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."

"On a scale of one to ten, where one is cheap and ten is expensive, I rate the pricing a three. It is a cheap solution."

"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's price is okay."

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

"Pricing-wise, it is not expensive as compared to other tools. If you have a couple of licenses, you can scan a certain number of projects. It just needs to be attached to them."
