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.

Role-based workflows have transformed daily deployments and improve team collaboration

GitLab has role-based access control, so when a team member needs to make a code change, they cannot directly apply it to the environment but must put in a merge request. Once a senior reviews the code and approves it, then it is implemented across the environment, making it safer and allowing everyone to experience the process. The best features GitLab offers are version control and automation, which are the major things that stand out to me. When it comes to access, the login is very smooth, with just one login integrated with our Okta, allowing everyone to log in easily. Deployments become much easier, and that is how GitLab helps. The automation features make my work easier because we use a tool called AWX, which is connected to GitLab. Whenever we run a job on AWX, it directly checks the code and uses it. Since the code is not preserved locally but kept in the cloud, it is safe and nobody can tamper with it. When it comes to safety, that is a major thing. Automation features allow the code to be accessed from any tools we use, so the jobs we run are helping tremendously and doing their work perfectly. For pipeline tasks, we have created a significant amount of pipelines, which are all hosted in GitLab. Running the pipelines has become much easier, and they are doing a perfect job, helping tremendously in our day-to-day activities. GitLab has positively impacted my organization because previously we stored code locally on servers, leading to many risks. Since GitLab came into our environment, our integration and deployments became much easier, helping our work become much smoother. Improvements from GitLab have led to better team collaboration because when several people are working, they can all edit the code and submit it as a merge request, and once approved, it reflects directly to the main branch. Many can work at the same time. When it comes to deployments, deploying has become much faster since we started using GitLab, and even if errors occur, we can spot them easily and troubleshoot, which has helped tremendously.

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."

"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."

"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."

"Simple and straightforward GUI."

"I like that it's easy to deploy our services over GitLab. The customer support is also good with a really active community. You have a lot of support that you can get online with your stack. That is probably one of the benefits of using GitLab. It's also really fast."

"The most valuable functionality of GitLab, for me, is the DevOps. Besides the normal source control based on Git, I find the Auto DevOps features most important in the solution."

"We have seen a couple of merge requests or pull requests raised in GitLab. I see the interface, the way it shows the difference between the two source codes, that it is easy for anyone to do the review and then accept the request; the pull request is the valuable feature."

"The SaaS setup is impressive, and it has DAST solutioning."

"GitLab integrates well with other platforms."

"CI/CD is very good. The version control system is also good. These are the two features that we use."

"It is user-friendly, easy to use, and easy to administer."

"GitLab has positively impacted my organization because previously we stored code locally on servers, leading to many risks, and since GitLab came into our environment, our integration and deployments became much easier, helping our work become much smoother."

Cons

"It requires understanding the Defensics protocol."

"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."

"You can't implement proprietary ciphering algorithms, nor can you modify protocol models if you need to test customized public protocols."

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

"Reporting could be improved."

"GitLab could improve by having more plugins and better user-friendliness."

"GitLab could consider introducing a code-scanning tool. Purchasing such tools from external markets can incur charges, which might not be favorable. Integrating these features into GitLab would streamline the pipeline and make it more convenient for users."

"GitLab should work on improving their user interface for GitOps as it is lagging behind."

"It could have more security integrations and the ability to check the vulnerability of the code. I don't think it is a responsibility of Gitlab, but it would be nice to have more options to integrate with."

"The self-hosted version of GitLab is not very stable when under load. It slows down and requires restarts every few days."

"GitLab could improve the patch repository. It does not have support for Conan patch version regions. Additionally, better support for Kubernetes deployment is needed as part of the package."

"We would like to have easier tutorials. Their tutorials are too technical for a user to understand. They should be more detailed but less technical."

More GitLab cons

Pricing and Cost Advice

"Licensing is a bit expensive."

"The solution is based on a subscription model and is reasonably priced."

"We are using its free version, and we are evaluating its Premium version. Its Ultimate version is very expensive."

"The solution's pricing is acceptable."

"GitLab is highly priced for smaller teams, but it's okay if considering a user base of thousands."

"We are using the open-source version."

"I don't mind the price because I use the free version."

"The price is okay."

"We are currently using the open-source version."
