Security Architecture for Food Supply Chains.
How Evidlane protects sensitive vendor contracts, proprietary allergen specifications, and GFSI audit evidence with bank-grade encryption and zero-trust ingestion.
Zero-Trust Ingestion & Storage Architecture
Every supplier upload is cryptographically isolated and virus-scanned before entering the encrypted vault.
1. Private Cloudflare R2 Vault
Supplier certificates and audit reports are never stored on public S3 buckets. All files reside in encrypted, private Cloudflare R2 buckets with presigned, time-limited download URLs (300s TTL).
2. Cryptographic Single-Use Tokens
Vendors access upload links generated with 32-byte high-entropy tokens. Tokens are stored strictly as SHA-256 hashes, auto-expire in 7 days, and invalidate immediately once evidence is submitted.
3. Strict Multi-Tenant Isolation
Every database query is forcefully scoped by organizationId. Role-Based Access Control (RBAC) separates Owner, Admin, and QA Reviewer permissions with server-side validation.
4. Automated Antivirus Quarantine
Uploaded files pass magic-byte verification and ClamAV virus scanning before they can be opened by your QA team. Infected or disguised payloads are quarantined instantly.
5. Zero Vendor Cross-Contamination
External suppliers can only view the exact evidence items requested from them. They have zero visibility into your other suppliers, pricing, or internal review commentary.
6. Immutable Audit Event Ledger
Every request creation, vendor upload, QA approval, certificate rejection reason, and export is recorded in an append-only audit log with timestamps and actor identities.
