A zero-credential execution boundary
Workflow code runs in an isolated process with no credentials and no direct access to external systems. Only trusted Services — separately deployed and auditable — can reach databases, secrets, or APIs.
Eliminate credential leakage without changing how workflows are written
Zero credentials in process
Workflow code runs with no database credentials, API keys, or secrets mounted. There is nothing to steal.
Trusted services only
Only separately-deployed Services can reach external systems. Workflows declare which Services they need — they never hold credentials directly.
Supply-chain isolation
A compromised dependency in workflow code cannot exfiltrate secrets or reach production systems — the process boundary holds.
Auditable service boundaries
Every access path from a workflow to an external system is explicit, versioned and reviewable. Prove exactly what can reach what.
Process-level isolation
User code runs in a sandboxed process separate from the orchestration layer. Crashes, infinite loops and malicious code cannot affect the runtime.
No workflow changes required
The boundary is transparent to authors. Existing Python workflows run unchanged — isolation happens at the infrastructure level.
