Room For Improvement

GitHub requires better usability, tool integration, project management, speed, security, documentation, merging, automation, storage, stability, and user interface.
Nucleus Security requires intuitive UI, enhanced reporting, streamlined integration, and better onboarding with customizable dashboards and exposure management.
When working with the CI/CD pipeline and somebody is writing the workflow file, it would be best to include the AI feature so if they write incorrect code, it will notify me about it in the same dashboard, eliminating the need to use third-party tools to review the file.
AWS & Azure Engineer at a media company with 11-50 employees
I am providing this feedback for Copilot because it seems more widespread and more companies allow it rather than Amp, and it would be beneficial if they catch up with Amp on this capability.
Senior Software Engineer at a tech services company with 501-1,000 employees
Security could make GitHub better. OWASP Top Ten security advisors could be integrated on GitHub, and it could provide checks and advice.
Software Development Manager at ANADOLU AGENCY
Nucleus Security needs a better view into exposure management, as exposure management and attack path management are missing.
Cyber Security Architect at a retailer with 10,001+ employees
Having more intuitive step-by-step visualized wizards or guided templates for building complex triage workflows would make the onboarding process much smoother for new team members.
Manager at a computer software company with 201-500 employees
It could be integrated with SentinelOne, but it was not showing any SentinelOne alerts.
Head of Security at a consultancy with 51-200 employees
 

Setup Cost

GitHub provides reasonable pricing and flexibility for enterprises, though improvements are needed for international markets and licensing complexities.
Enterprise users appreciate Nucleus Security's competitive pricing, straightforward licensing, and value-driven features despite initial costs.
I have not encountered any initial setup cost for that.
Full Stack Developer at Sri Krishna Arts and Science
Normally, GitHub is not expensive, but it would be welcome if it reduces costs for developing countries.
Lead Software Engineer at The 5 Chairs
The pricing of GitHub is reasonable, with the cost being around seven dollars per user per month for private repositories.
QA Manager at Next Solutions
The licensing model is straightforward, with one license across multiple assets for multiple connectors.

Full Stack Developer at Sri Krishna Arts and Science
Daily workflows have become streamlined as I manage projects, learn from clones, and host sites
The thing that has frustrated me is sometimes when I push using a Git command, I need to force the push, which is the main thing. The setup is frustrating because GitHub could add a repository with pre-installed packages or something since I need to install packages in VS Code before pushing and maintain it in the codebase. Git packages need to be installed manually, and if that was already in a GitHub repository, that would be much better. GitHub packages can be installed previously for the project upon the project requirement, and that is the thing I wanted to add here. That would be good. According to governance and security, I recently heard about some security issues in GitHub. I think that could be centralized and should consider those security issues and clear them. The AI capabilities there include Copilot or something else. I recently heard about security issues, but I do not know about it clearly. However, if security has been more tightened, it will be better.

Vulnerability And Compliance Manager at a insurance company with 5,001-10,000 employees
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.
