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, and because of that, we can eliminate a lot of unwanted test cases so we can execute the tests and complete them very quickly."
"Simple and straightforward GUI."
"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 stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."
"GitLab is very useful for pipelines, continuous integration, and continuous deployment. It is also stable."
"It is a speedy platform compared to the others I have used, and I have also enjoyed using the platform as this solution offers a good user experience."
"The most valuable features of GitLab are the review, patch repo, and plans are in YAML."
"We have been using this solution for more than five years, and it is deployed on cloud."
"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."
"It is very flexible and easy because you can store data on cloud."
"The most valuable feature of GitLab is the automatic merging of code."
"Overall, this is a good product that has a lot of features."
 

Cons

"Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install."
"It requires understanding the Defensics protocol."
"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."
"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."
"GitLab's UI could be improved."
"Perhaps the integration could be better."
"In my experience, GitLab is stable; however, sometimes it takes much time to start the runner and gets stuck in a pending situation, possibly due to traffic issues."
"The technology could be made simpler to use, it should not be overly complex."
"The pricing has been substantially increased, which is a major concern."
"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."
"When deploying the solution on cloud and the CI/CD pipeline, we have to define the steps and it becomes confusing."
"At this point, I think the features are declining."
 

Pricing and Cost Advice

"Licensing is a bit expensive."
"GitLab is an open-source solution."
"Its price is fine. It is on the cheaper side and not expensive. You have to pay additionally for GitLab CI/CD minutes. Initially, we used the free version. When we ran out of GitLab minutes, we migrated to the paid version."
"The initial setup cost is excellent and you can add the premium features later."
"GitLab is highly priced for smaller teams, but it's okay if considering a user base of thousands."
"It is very expensive. We can't bear it now, and we have to find another solution. We have a yearly subscription in which we can increase the number of licenses, but we have to pay at the end of the year."
"We are using the free version of GitLab."
"The price of GitLab could be better, it is expensive."
"I'm not aware of the licensing costs because those were covered by the customer."
