SentinelShare
Military-grade secure file transfer. Share sensitive documents with end-to-end encryption, ephemeral links, and immutable audit logs.
Advanced Capabilities
End-to-End Encryption
Files are encrypted locally using AES-256 before transmission. We do not hold the decryption keys, ensuring complete data sovereignty.
Ephemeral Links
Generate time-bound access links that self-destruct after 24 hours, or after a specific number of successful downloads.
Immutable Audit Logs
Maintain a cryptographic ledger of all file accesses, modifications, and downloads, designed to meet stringent compliance requirements.
Designed for the Enterprise
Legal & Compliance
Share contracts, IP documentation, and M&A materials with external counsel without risking interception or lingering access.
Healthcare (HIPAA)
Transmit PHI (Protected Health Information) securely to partners and patients using our HIPAA-compliant, zero-knowledge architecture.
Financial Services
Exceed SEC and FINRA regulations when sharing financial models, trading algorithms, or sensitive client portfolio data.
Frequently Asked Questions
What is the maximum file size limit?
Enterprise plans allow for single-file transfers of up to 500GB, leveraging our optimized delta-sync protocols to handle massive datasets seamlessly.
Can we host SentinelShare on-premise?
Yes. While our cloud offering is strictly zero-knowledge, we offer self-hosted and air-gapped deployment options for high-security environments.
How does the audit log work?
Every action is cryptographically signed and appended to a write-only ledger, which can be exported directly to your SIEM (e.g., Splunk, Datadog).
