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.

Unified vulnerability view has improved risk-based decisions but reporting still needs work
One of the main issues with Nucleus Security is its lack of reporting capability. The user interface resembles an early 2000s application style, and although its speed is decent, it could be improved as more data is ingested. The overall appearance and feel need work, especially compared to modern applications from Rapid7, Qualys, and Tenable, which have more engaging user interfaces. The reporting capability is severely lacking; not being able to filter to granularity or have custom built queries is an annoyance that needs an overhaul. Additionally, there are bugs that have not been resolved, such as when you create a report and remove an asset, the asset still appears in the report despite not being present in the system anymore, leading to issues that need to be addressed quickly. Nucleus Security can become a difficult investment because I already have a vulnerability management solution, and I question where Nucleus Security fits with its licensing model. While I acknowledge automation has been described, it would be amazing to control the entire vulnerability management workflow from Nucleus Security without needing to log onto other systems. Having controls or actions that can be sent from the console down to the scanner for rescans would be beneficial. If Nucleus Security is going down this path, it should ensure that it becomes a one-stop shop for vulnerability management across multiple applications.
