Zero-Knowledge Security Architecture
How Vyntech Secrets Vault protects sensitive API tokens, private keys, and environment variables against memory inspection, data store exfiltration, and unauthorized actor traversal.
1. In-Memory Ephemeral Handling
Plaintext secret buffers are allocated in protected memory slices and zeroed out immediately after HTTP response serialization. Secrets are never persisted unencrypted on application disks or swap partitions.
2. Multi-Replica Distributed Rate Limiting
Service Account authentication attempts are throttled via distributed Redis sliding windows (audit recommendation #11), preventing credential guessing and timing side-channel attacks across scaled API replicas.
3. Database Multi-Tenant Isolation
Secrets utilize dedicated PostgreSQL database pools (vyntech_secrets) segregated from platform logs and web telemetry, ensuring cross-database containment.
