Product security tests for switches and router sections
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.

Improved agility and time to market with CI/CD enhancements
The CI/CD pipelines in GitLab are highly valuable. Another important feature is the single source of repository, allowing efficient repository management and source code management. GitLab provides manageability by allowing us to manage source code effectively through separate repositories. Additionally, GitLab enables the creation of individual CI/CD pipelines for each repository, making software more agile. By integrating GitLab as a DevOps platform, we have enhanced agility, improved our time to market, and different teams can work collaboratively on various projects.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."
"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... Because of that, we can eliminate a lot of unwanted test cases, so we can execute the tests and complete them very quickly."
"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."
"I have had no problem with the stability of the solution."
"GitLab's best features are maintenance, branch integration, and development infrastructure."
"It is very flexible and easy because you can store data on cloud."
"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."
"It speeds up our development, it's faster, safer, and more convenient."
"I have found the most valuable feature is security control. I also like the branching and cloning software."
"Key features allow creation of well-presented Wiki that includes ideas, development, and domains."
 

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."
"I would like to have some features to support peer review."
"I would like configuration of a YML file to be done via UI rather than a code file."
"It has fewer options, and its UI is not so user-friendly."
"As GitLab is not perfect, what needs improvement in the solution is the Wiki feature of the groups or the repertories because currently, it's not searchable by default. You'll need an indexing service such as Elasticsearch to make it searchable, and that requires too much work, so for me, it's the main feature that should be improved in GitLab. In the next version of the solution, from the top of my head, the documentation could be improved. Besides the Wiki, it would be good if there's documentation that would be automatically generated based on the code repository. In other words, there should be some tutorials from GitLab for developers in the next release."
"We'd like to see better integration with the Atlassian ecosystem."
"The integration could be slightly better."
"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."
"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."
 

Pricing and Cost Advice

"Licensing is a bit expensive."
"The solution's pricing is acceptable."
"The initial setup cost is excellent and you can add the premium features later."
"GitLab is comparatively expensive, but it provides value because it's feature-rich."
"The price of GitLab could be better, it is expensive."
"The open-source version is very good and the commercial version is reasonably priced."
"My company uses the free version of GitLab, which is GitLab Community Edition. There is a licensed version also available for GitLab."
"The solution is free."
"GitLab is cheap."

What do you like most about GitLab?
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.
What is your experience regarding pricing and costs for GitLab?
We are currently using general GitLab, not GitLab Premium.
What needs improvement with GitLab?
GitLab needs to improve the CI/CD functionality because it is not compatible with Jenkins and other tools, as it is not that efficient. Security-wise, we have security features enabled in GitLab fo...
