KMS vs Secrets Manager: How Key Management and Secrets Management Differ

When GitGuardian analyzed thousands of compromised developer machines, on average, each live secret turned up in eight different places, from .env files and shell history to IDE settings and build artifacts. Credentials spread to wherever developers and their tools need them, and the two systems built to contain that spread,
