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."
"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."
"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."
"Previously we used Team Foundation Server, but GitLab is better for local cloud deployment."
"I have had no problem with the stability of 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."
"Their CI/CD engine is very mature. It's very comprehensive and flexible, and compared to other projects, I believe that GitLab is number one right now from that perspective."
"Git merging allows us to track the details of how and who has done what; this is the best feature which is useful for all companies."
"The feature I appreciate the most about GitLab is its ease of use and compatibility, which allows for straightforward building and deployment processes."
"I was satisfied with the support."
"I find the features and version control history to be most valuable for our development workflow. These aspects provide us with a clear view of changes and help us manage requests efficiently."
 

Cons

"It requires understanding the Defensics protocol."
"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."
"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."
"I rate the support from GitLab a four out of five."
"The documentation could be improved to help newcomers better understand things like creating new branches."
"Technologies are always changing. Nowadays, new things like serverless computing and workload management have emerged. We have noticed a few gap items for faster service delivery. For example, we do user interface testing in the latest team and automate it using some tools. Recently, we integrated a tool with user interface testing, which can simulate a multi-user environment. So, we would like to see more integration with different platforms."
"Merge conflicts and repository maintenance could improve. If there is someone new to the system they would not know if there is a conflict."
"GitLab can improve by integrating with more tools, such as servers with Docker."
"The deployment and performance of GitLab could be better. In addition, the solution could be faster."
"There is a need to improve or adopt AI into the ecosystem like a co-pilot, which Microsoft has done with GitHub."
"There are occasions where we usually see a lot of outages using GitLab; it happens at least once a week or something like that."
 

Pricing and Cost Advice

"Licensing is a bit expensive."
"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."
"This is an open-source solution."
"GitLab is comparatively expensive, but it provides value because it's feature-rich."
"The initial setup cost is excellent and you can add the premium features later."
"In total, I believe we have more than 300 licenses spread over about 100 users, though I can't comment on the costs involved."
"GitLab's pricing is good compared to others on the market."
"There are different licensing options available, including a free limited-user license."
"I don't mind the price because I use the free version."
