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

"Simple and straightforward GUI."
"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."
"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."
"The stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
"Key features allow creation of well-presented Wiki that includes ideas, development, and domains."
"GitLab is very well-organized and easy to use. Also, it offers most features that customers need."
"Gitlab is also more customizable."
"Of all available products, it was the easiest to use and easy to install."
"GitLab is kind of an image of GitHub, so it gives us the flexibility to monitor our changes in the repos."
"GitLab is a wholly complete solution and it is for this reason that I can recommend it to other users."
"The solution is similar to all the repository tools or the work tools on the market, and I like it and find it quite easy to use."
"Continuous integration with deployment is very powerful, which is a significant reason for migrating from TFS to GitLab."
 

Cons

"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."
"You can't implement proprietary ciphering algorithms, nor can you modify protocol models if you need to test customized public protocols."
"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."
"Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install."
"The only feature I have used in GitLab that I thought could be improved is their code generation feature."
"We had to write GitLab configuration files, commands and conditions, in a YML format. I would like configuration of a YML file to be done via UI rather than a code file."
"The self-hosted version of GitLab is not very stable when under load. It slows down and requires restarts every few days."
"There are occasions where we usually see a lot of outages using GitLab; it happens at least once a week or something like that."
"GitLab can improve its user interface to make conflict resolution more user-friendly."
"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."
"Some of the scripts that we encountered in GitLab were not fully functional and threw up errors."
"I would like to see static analysis also embedded in GitLab. That would also help us. If there's something that it does internally by GitLab and then that is already tied up with your pipeline and then it can tell you that you're coding is good or your code is not great. Based on that, it would pass or fail. That should be streamlined. I would think that would help to a greater extent, in terms of having one solution rather than depending on multiple vendors."
 

Pricing and Cost Advice

"Licensing is a bit expensive."
"This is an open-source solution."
"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."
"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."
"The open-source version is very good and the commercial version is reasonably priced."
"GitLab is a free solution to use."
"I'm not aware of the licensing costs because those were covered by the customer."
"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 price is okay."

What is your experience regarding pricing and costs for GitLab?
I was using the free version of GitLab , but I think the price is comparative and not a major differentiator.
What needs improvement with GitLab?
Since GitLab [Private Offer Only] the main part is the Git part. With AI being available, I see one thing happening. For example, Claude Code allows people to connect Jira or ClickUp, and then they...
What is your primary use case for GitLab?
My basic use case for Gitlab was the ticket management, the wiki, the CI/CD pipeline, and the code repository. These four use cases form my core usage.
