Zero Trust SDLC: Applying Zero Trust Principles Across the Software Development Lifecycle

74% of Software Security Risks Originate with Developers—Human and AI.

Yet most Zero Trust initiatives stop at infrastructure, runtime, and network boundaries. When security risk originates during software development, organizations often lack visibility into how risk entered the SDLC, which action introduced it, and who—human or AI—was responsible.

Zero Trust SDLC addresses this blind spot by extending Zero Trust principles into the software development lifecycle—ensuring that no action, tool, or workflow is implicitly trusted during development.

Archipelo enables Zero Trust SDLC through developer-level observability and telemetry—linking developer identity and actions to proactively identify and mitigate risks before, during, and after code is committed.

What is Zero Trust SDLC?

Zero Trust SDLC is not a new security framework and not a replacement for Zero Trust architectures, IAM platforms, or CI/CD controls.

It is the application of Zero Trust principles—continuous validation, attribution, and least privilege—across the software development lifecycle.

In practice, Zero Trust SDLC is enabled by Developer Security Posture Management (DevSPM), which acts as the system of record linking scan results, vulnerabilities, and policy violations to developer and AI agent identity and actions across the SDLC.

This enables organizations to:

  • Continuously validate actions across development workflows

  • Attribute security findings to identity and behavior

  • Govern tools and integrations used throughout the SDLC

  • Preserve audit-ready evidence tied to how software was created

Without developer-aware visibility, Zero Trust programs cannot meaningfully extend into development.

Traditional Zero Trust implementations focus on access control and runtime enforcement. However, when risk is introduced during development, security teams often cannot answer:

  • How did this risk enter the SDLC?

  • Which commit, pull request, or tool introduced it?

  • Was the action human-driven or AI-assisted?

  • Is this behavior recurring across teams or repositories?

This lack of visibility leaves organizations exposed to:

  • Insider Threats. Compromised credentials or misuse of access can introduce risk long before deployment.

  • Shadow IT Across the SDLC. Unapproved developer tools, IDE plugins, or CI/CD integrations expand the attack surface without detection.

  • Risky Development Practices. Insecure dependencies, leaked secrets, or flawed AI-generated code can propagate silently through trusted workflows.

Zero Trust SDLC requires identity-aware telemetry to validate actions at the point where software risk originates.

Why Zero Trust Breaks Down in the SDLC
Real-World Signals Driving Zero Trust SDLC

Security incidents consistently demonstrate how development-stage risk bypasses traditional Zero Trust controls:

  • Insider Threat and Identity Failures: Uber Breach (2022) Exploited developer credentials allowed hackers to access sensitive internal systems, exposing user data and demonstrating the consequences of poor identity and access controls.

  • AI-Generated Code Flaws: GitHub Copilot Issue (2024) Research revealed that AI-generated code occasionally suggested insecure solutions, introducing vulnerabilities into applications if your existing codebase already contains security issues. Zero Trust SDLC ensures rigorous checks for AI-assisted code to prevent vulnerabilities.

How Archipelo Supports Zero Trust SDLC

Archipelo enables Zero Trust SDLC by making actions across the SDLC observable—human and AI—through Developer Security Posture Management.

Archipelo creates a historical record of coding events across the SDLC tied to developer identity and actions, providing the attribution and context required for continuous validation.

Key Capabilities:

  • Developer Vulnerability Attribution
    Trace scan results and vulnerabilities to the developers and AI agents who introduced them.

  • Automated Developer & CI/CD Tool Governance
    Scan developer and CI/CD tools to verify tool inventory and mitigate shadow IT risks across the SDLC.

  • AI Code Usage & Risk Monitor
    Monitor AI code tool usage to ensure secure and responsible software development.

  • Developer Security Posture
    Generate insights into security risks introduced by actions across teams and workflows.

These capabilities provide the foundation required to apply Zero Trust principles throughout the SDLC—without redefining existing Zero Trust architectures.

Zero Trust SDLC as a Security Outcome

Zero Trust SDLC is not achieved through blanket restrictions or reactive controls.

It is achieved by ensuring that every action within the SDLC is attributable, auditable, and governable.

By enabling Developer Security Posture Management, organizations can:

  • Validate actions across development workflows

  • Reduce investigation time through identity-based attribution

  • Strengthen compliance evidence

  • Address root cause instead of recurring symptoms
