Security

1. Data Encryption

All data in transit is secured using TLS 1.3. Data at rest, including email routing metadata and active message payloads, is encrypted using AES-256 block-level encryption.

2. Network Perimeters

Unsendbox operates as a multi-region network edge. Direct database access is blocked via strict VPC perimeters, and all administrative actions require phishing-resistant MFA.

3. Vulnerability Reporting

If you discover a security vulnerability, please report it immediately to security@unsendbox.io. We review all reports within 24 hours.
