Software supply chain attacks are surging at an unprecedented rate. According to SecurityWeek, these attacks have increased by 742% in the past three years, making it clear that traditional security measures are no longer enough. In response, the Supply-chain Levels for Software Artifacts (SLSA) framework was developed to help organizations fortify their software development processes from end to end.
What is SLSA Framework?
Source: SLSA
The SLSA Framework (Supply-chain Levels for Software Artifacts), pronounced “salsa”, is a comprehensive security framework that protects software from development to deployment. It defines four levels of security, each building on the previous one to improve software safety and transparency throughout its lifecycle.
Here’s a quick overview of the four levels:
- Level 1: Basic Integrity – Ensures automated builds and controlled environments, laying the foundation for traceability.
- Level 2: Provenance – Tracks the origins of software artifacts, ensuring they can be traced back to their source.
- Level 3: Security – Implements access controls and reproducible builds to detect tampering.
- Level 4: Maximum Security – Provides the highest level of protection with tamper-proof, hermetic builds and strict provenance controls.

SLSA aims to create a comprehensive, adaptable framework that addresses critical pieces of software supply chain security
Why SLSA is Critical for CI/CD Pipelines
As DevOps practices and CI/CD pipelines accelerate software development, they also expose vulnerabilities. Attackers can exploit these gaps, injecting malicious code or tampering with dependencies. SLSA addresses these challenges by ensuring that every step of the development process is secure, transparent, and verifiable.
- Visibility and Traceability: SLSA tracks every change and component in your pipeline, making it easier to detect vulnerabilities early.
- Proactive Defense: It identifies and mitigates risks before they can be exploited.
- Standardization: SLSA provides a recognized standard for securing software artifacts, ensuring consistency across development processes.
How Xygeni Supports SLSA Compliance
Achieving SLSA compliance can be challenging, especially for fast-moving development environments. This is where Xygeni comes in. Our platform automates critical security tasks, ensuring your software supply chain meets and exceeds SLSA standards without slowing down your workflow.
1. Automated Build Integrity – Level 1
Xygeni integrates seamlessly into your CI/CD pipelines, automating builds and monitoring every step to ensure consistency and integrity. This automation lays the foundation for compliance with SLSA Level 1, where continuous build monitoring ensures that each build follows secure processes, eliminating manual errors and maintaining compliance from the start.
2. Provenance and Traceability – Level 2
Provenance tracking becomes crucial at SLSA Level 2. Xygeni tracks every software component across your pipeline, generating immutable records that ensure everything can be traced back to its original source. By providing full provenance generation and tracking, Xygeni ensures that all steps in the software lifecycle are transparent and verifiable, securing your software’s integrity.
3. Enhanced Security Controls – Level 3
At SLSA Level 3, security is significantly enhanced. Xygeni introduces advanced controls such as dependency mapping and access management to ensure that all third-party components are properly reviewed. This real-time dependency analysis identifies critical risks, while reachability analysis filters out non-exploitable vulnerabilities, allowing your team to focus on addressing the most significant threats.
4. Hermetic Builds and Maximum Security – Level 4
For SLSA Level 4, hermetic builds are essential, isolating the build environment from external dependencies. Xygeni ensures every build is secure and tamper-proof by automatically verifying build attestations and maintaining tamper-proof logs. This gives you complete confidence that every software artifact is safe and compliant with the highest level of security.
Best Practices for Implementing the SLSA Framework
Integrating the Supply-chain Levels for Software Artifacts framework into your workflows requires balancing security with efficiency. By starting small, engaging stakeholders, leveraging automation, and iterating based on feedback, you can secure your software supply chain while maintaining agility. Here’s how Xygeni supports each step.
1. Conduct a Preliminary Assessment
Evaluate your current software development processes and identify gaps relative to SLSA requirements. Xygeni helps map critical assets and dependencies. It identifies vulnerabilities and highlights areas for improvement to meet SLSA standards.
2. Engage Stakeholders Early
Secure buy-in from development, security, and operations teams by showing the benefits of SLSA integration, such as reduced supply chain risks. Xygeni provides clear reports, making it easy for stakeholders to track progress and understand the value of SLSA.
3. Start Small and Scale Gradually
Pilot a project to test SLSA practices on a small scale. Scale to larger projects as your team becomes more comfortable. Xygeni’s tools make it easy to start and gradually apply SLSA practices, beginning with automated builds and tracking the origins of your software.
4. Integrate SLSA Practices into Existing Workflows
Use automation to embed SLSA practices into your CI/CD pipelines, minimizing manual effort and ensuring consistency. Xygeni integrates deeply with CI/CD pipelines, automating security tasks like build monitoring, dependency analysis, and provenance generation.
5. Provide Training and Resources
Ensure teams fully understand SLSA requirements through training programs and clear documentation. Xygeni offers support with training and onboarding, providing user-friendly interfaces and detailed reports for easy adaptation.
6. Regularly Review and Iterate
Regularly review the effectiveness of SLSA practices and adjust based on feedback. Xygeni’s detailed reports and analytics allow you to regularly monitor and adjust your security strategies.
7. Leverage SLSA Community Resources
Engage with the SLSA community for best practices and contribute back to share your experiences. Xygeni supports compliance and helps your organization stay connected with broader security efforts.
8. Monitor and Enforce Compliance
Implement real-time monitoring and automated enforcement mechanisms to ensure continuous compliance with SLSA. Xygeni continuously monitors compliance and sends automated alerts for any vulnerabilities, especially in third-party components. Security enforcement is integrated directly into your CI/CD pipeline.
Securing Your Future with Xygeni and SLSA
Securing your software supply chain is no longer a choice—it’s a must. The SLSA framework gives you a clear plan to protect your software, from basic security to advanced tamper-proof methods. With Xygeni, you can simplify compliance and grow your security measures easily, keeping your software safe, strong, and ready for the future.
