Open-source dependencies are your biggest attack surface. We explain how Nexus Repository and Lifecycle protect your codebase before vulnerabilities reach production.
## Software Supply Chain Security
In 2021, the SolarWinds attack demonstrated that software supply chains are one of the most dangerous attack vectors in enterprise IT. Since then, securing the software supply chain has become a top priority for banks, governments, and large enterprises worldwide.
### What is a Software Supply Chain Attack?
A supply chain attack occurs when malicious code is introduced into a software dependency — a library or package that your application relies on. Because developers trust these dependencies, the malicious code can reach production undetected.
### The Open Source Risk
Over 80% of modern applications contain open-source components. Each component can have dozens of transitive dependencies — and any one of them could contain a known vulnerability or malicious code.
### How Sonatype Nexus Protects You
**Nexus Repository** acts as a proxy between your developers and public repositories like Maven Central, npm, and PyPI. All dependencies are cached and scanned before they reach your developers.
**Nexus Lifecycle** integrates into your CI/CD pipeline and automatically scans every build for known vulnerabilities, license violations, and policy breaches — blocking risky components before they reach production.
### Key Capabilities
- Real-time vulnerability scanning against the Sonatype OSS Index
- Automatic quarantine of malicious components
- License compliance management
- Developer-friendly remediation guidance
- Integration with GitLab, Jenkins, and Azure DevOps
### Our Experience
IT ADMINZ has deployed Sonatype Nexus for Banque Misr — one of Egypt's largest banks — enabling their development teams to manage artifacts securely and comply with software governance requirements.
### Conclusion
In today's threat landscape, every dependency is a potential attack vector. Sonatype Nexus gives your team visibility and control over every component in your software supply chain — before it becomes a breach.
