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

"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, and 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."
"Simple and straightforward GUI."
"The stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
"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."
"The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."
"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."
"I like GitLab's security and SAS tools."
"The solution's most valuable features are pipelines."
"GitLab offers a good interface for doing code reviews between two colleagues."
"The feature I appreciate the most about GitLab is its ease of use and compatibility, which allows for straightforward building and deployment processes."
"I like that it's easy to deploy our services over GitLab; the customer support is also good with a really active community, and you have a lot of support that you can get online with your stack, which is probably one of the benefits of using GitLab, and it's also really fast."
"CI/CD and GitLab scanning are the most valuable features."
"Gitlab is also more customizable."
 

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."
"You can't implement proprietary ciphering algorithms, nor can you modify protocol models if you need to test customized public protocols."
"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."
"It requires understanding the Defensics protocol."
"In the next release, I would like to see GitLab expand its integration capabilities to include platforms like DigitalOcean, which developers widely use for cloud infrastructure. Enhancing CI/CD automation features specifically tailored for DigitalOcean would be beneficial."
"The solution does not have many built-in functions or variables so scripting is required and that is a drawback."
"It would be better if there weren't any outages. There are occasions where we usually see a lot of outages using GitLab. It happens at least once a week or something like that. Whatever pipelines you're running, to check the logs, you need to have a different set of tools like Argus or something like that. If you have pipelines running on GitLab, you need a separate service deployed to view the logs, which is kind of a pain. If the logs can be used conveniently on GitLab, that would be definitely helpful. I'm not talking about the CI/CD pipelines but the back-end services and microservices deployed over GitLab. To view the logs for those microservices, you need to have separate log viewers, which is kind of a pain."
"The integration and storage capabilities could be better."
"There is a need to improve or adopt AI into the ecosystem like a co-pilot, which Microsoft has done with GitHub."
"When deploying the solution on cloud and the CI/CD pipeline, we have to define the steps and it becomes confusing."
"We are having a few problems integrating with Jira at the moment, which is something that our IT department is investigating."
"It should be used by a larger number of people. They should raise awareness."
 

Pricing and Cost Advice

"Licensing is a bit expensive."
"We are currently using the open-source version."
"We are using the free version of GitLab."
"As I work in a vast enterprise, I'm unsure about the licensing cost for GitLab. It's the management team that takes care of that."
"The solution's pricing is acceptable."
"We are using the open-source version."
"GitLab's pricing is good compared to others on the market."
"GitLab is an open-source solution."
"The price of GitLab could be better, it is expensive."
