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."
"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."
"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."
"The stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
"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 code merging capability is something that we use very frequently."
"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."
"I have had no problem with the stability of the solution."
"GitLab is scalable and works well with multiple environments."
"The source-code repository is great, I really like the pipelines, and the stability is good."
"We also found the straightforward setup, stability, and scalability of GitLab valuable."
"My advice for others looking into this product is to go for it; GitLab is the future."
"The most important features of GitLab for us are issue management and all the CI/CD tools. Another aspect that I love about GitLab is the UI."
 

Cons

"It requires understanding the Defensics protocol."
"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."
"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."
"Its security features are very expensive. The Ultimate version is very expensive."
"The integration could be slightly better."
"The only feature I have used in GitLab that I thought could be improved is their code generation feature."
"GitLab doesn't have AWS integration."
"As a partner, sometimes it's difficult to get support. They have a really complicated procedure for their support."
"The solution could improve by having better integration."
"It could have more security integrations and the ability to check the vulnerability of the code. I don't think it is a responsibility of Gitlab, but it would be nice to have more options to integrate with."
"The user interface could be more user-friendly. We do most of our operations through the website interface but it could be better."
 

Pricing and Cost Advice

"Licensing is a bit expensive."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a five out of ten."
"I think that we pay approximately $100 USD per month."
"We are using the open-source version."
"We are using its free version, and we are evaluating its Premium version. Its Ultimate version is very expensive."
"GitLab is an open-source solution."
"The price of GitLab could be better, it is expensive."
"The initial setup cost is excellent and you can add the premium features later."
"I don't mind the price because I use the free version."
