Confidential Employee Dossier Vault
Employee documents are stored in private S3 buckets with zero public access. Downloads and viewing requests require cryptographic token issuance yielding short-lived signed URLs with a maximum 60-second time-to-live.
Documents are categorized by taxonomy (Contract, Tax, Identity, Certification, Compliance, Policy) with strictly enforced Row Level Security.
Supported Document Types & File Integrity Protection
To counter disguised file threats where malicious files or executables are disguised with harmless document extensions (such as invoice.pdf or badge.png), Sferafy executes deep binary signature verification on upload.
Files are accepted only when their binary signatures strictly conform to authorized enterprise document and image specifications, while executable headers are blocked at the edge before storage writes.
Proactive Expiry Radar & Urgency Thresholds
Visas, NDAs, contracts, and safety certifications have strict legal validity windows. The Document Expiry Radar categorizes all active dossiers into urgency classifications:
• Critical (≤ 3 days or already expired): Prominent dashboard alert requiring urgent attention.
• Warning (≤ 14 days): Priority alert in the HR administrator control center.
• Notice (≤ 30 days): Informational reminder dispatched via transactional email.
