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

"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."
"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."
"The stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
"Simple and straightforward GUI."
"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."
"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."
"I like that you can use GitLab as a double-sided solution for both DevOps and version management. It's a good product for working in these two areas, and the user interface makes it easy to understand."
"It is very flexible and easy because you can store data on cloud."
"GitLab is a solution for source code management, container registry, pipelines, testing, and deployment."
"This product is always evolving, and they listen to the customers."
"If you want to maintain your issues in GitLab and raise your book of work and features, then GitLab is a great tool for collaboration and integration with code deployment and CICD pipelines."
"CI/CD is very good. The version control system is also good. These are the two features that we use."
"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."
 

Cons

"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."
"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."
"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."
"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."
"It requires understanding the Defensics protocol."
"GitLab would be improved with the addition of templates for deployment on local PCs."
"In the free version, when a merge request is raised, there is no way to enforce certain rules. We can't enforce that this merge request must be reviewed or approved by two or three people in the team before it is pushed to the master branch. That's why we are exploring using some agents."
"I would like more Agile features in the Premium version. The Premium version should have all Agile features that exist in the Ultimate version. IBM AOM has a complete Agile implementation, but in GitLab, you only have these features if you buy the Ultimate version. It would be good if we can use these in the Premium version."
"I have encountered issues with the deployment of CI/CD pipelines, especially dealing with variable environments."
"Their RBAC is role-based access, which is fine but not very good."
"I don't really like the new way because it is pretty focused on the on-premise environment, but we're in a hybrid environment."
"Currently, GitLab is not easy to scale because GitLab has specific deployment instructions. We deploy it on one of the VMs."
"The pricing model of GitLab is an issue for me."
 

Pricing and Cost Advice

"Licensing is a bit expensive."
"The initial setup cost is excellent and you can add the premium features later."
"The open-source version is very good and the commercial version is reasonably priced."
"The price is okay."
"GitLab is a free solution to use."
"GitLab is an open-source solution."
"We are currently using the open-source version."
"I think that we pay approximately $100 USD per month."
"In terms of the pricing for GitLab, on a scale of one to five, with one being expensive and five being cheap, I'm rating pricing for the solution a four. It could still be cheaper because right now, my company has a small team, and sometimes it's difficult to use a paid product for a small team. You'd hope the team will grow and scale, but currently, you're paying a high license fee for a small team. I'm referring to the GitLab license that has premium features and will give you all features. This can be a problem for management to approve the high price of the license for a team this small."
