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."

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

"What is valuable about Snyk is its simplicity."

"I am impressed with the product's security vulnerability detection. My peers in security are praising the tool for its accuracy to detect security vulnerabilities. The product is very easy to onboard. It doesn't require a lot of preparation or prerequisites. It's a bit of a plug-and-play as long as you're using a package manager or for example, you are using a GitHub repository. And that is an advantage for this tool because developers don't want to add more tools to what they're currently using."

"It has a nice dashboard where I can see all the vulnerabilities and risks that they provided. I can also see the category of any risk, such as medium, high, and low. They provide the input priority-wise. The team can target the highest one first, and then they can go to medium and low ones."

"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."

"The most valuable feature is that they add a lot of their own information to the vulnerabilities. They describe vulnerabilities and suggest their own mitigations or version upgrades. The information was the winning factor when we compared Snyk to others. This is what gave it more impact."

"The solution's Open Source feature gives us notifications and suggestions regarding how to address vulnerabilities."

"The most effective feature in securing project dependencies stems from its ability to highlight security vulnerabilities."

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

Cons

"It does not support the complete protocol stack. There are some IoT protocols that are not supported and new protocols that are not supported."

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

"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."

"We have seen cases where tools didn't find or recognize certain dependencies. These are known issues, to some extent, due to the complexity in the language or stack that you using. There are some certain circumstances where the tool isn't actually finding what it's supposed to be finding, then it could be misleading."

"It would be great if they can include dynamic, interactive, and run-time scanning features. Checkmarx and Veracode provide dynamic, interactive, and run-time scanning, but Snyk doesn't do that. That's the reason there is more inclination towards Veracode, Checkmarx, or AppScan. These are a few tools available in the market that do all four types of scanning: static, dynamic, interactive, and run-time."

"I would like to give further ability to grouping code repositories, in such a way that you could group them by the teams that own them, then produce alerting to those teams. The way that we are seeing it right now, the alerting only goes to a couple of places. I wish we could configure the code to go to different places."

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

"Compatibility with other products would be great."

"The way Snyk notifies if we have an issue, there are a few options: High vulnerability or medium vulnerability. The problem with that is high vulnerabilities are too broad, because there are too many. If you enable notifications, you get a lot of notifications, When you get many notifications, they become irrelevant because they're not specific. I would prefer to have control over the notifications and somehow decide if I want to get only exploitable vulnerabilities or get a specific score for a vulnerability. Right now, we receive too many high vulnerabilities. If we enable notifications, then we just get a lot of spam message. Therefore, we would like some type of filtering system to be built-in for the system to be more precise."

"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..."

Pricing and Cost Advice

"Licensing is a bit expensive."

"Their licensing model is fairly robust and scalable for our needs. I believe we have reached a reasonable agreement on the licensing to enable hundreds of developers to participate in this product offering. The solution is very tailored towards developers and its licensing model works well for us."

"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."

"It's good value. That's the primary thing. It's not cheap-cheap, but it's good value."

"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."

"For what Snyk offers, it has the best cost-benefit I have ever seen because you're buying the license per user."

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

"The pricing is reasonable."

"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."
