The SecureShare file manager — encrypted storage, sharing, and upload requests in one place.
SecureShare is the enterprise platform for encrypted file storage, sharing, and governance — strong cryptography, granular access control, and a tamper-evident audit trail in one deployable platform.

The SecureShare file manager — encrypted storage, sharing, and upload requests in one place.
The tools most teams use were built for convenience, not control. Once a file leaves your hands, you rarely know who opened it, when it expires, or whether it can be recovered, revoked, or proven untouched.
Consumer clouds and email hold your plaintext. SecureShare offers true end-to-end encryption where even the operator can't read it.
Shared links rarely expire and can't be pulled back. SecureShare gives you expiration, download limits, and instant revocation.
Most tools can't tell you who accessed what. SecureShare keeps a complete, tamper-evident audit trail of every action.
Regulated industries — healthcare, finance, legal, government — can't accept those trade-offs. They need to share data and retain control, visibility, and provability. SecureShare is built for exactly that intersection.
Every file is protected with modern authenticated encryption. Choose transparent server-side, or password-protected client-side (zero-knowledge) encryption.
Expiring links, download limits, password protection, granular permissions, and instant revocation — sharing a file never means losing control of it.
Retention, legal hold, and a tamper-evident audit log help compliance and legal teams show what happened — for GDPR, NIS2, DORA, and beyond.
Upload to your tenant and pick the encryption that fits the sensitivity — transparent server-side, or password-protected client-side (zero-knowledge).
Structure files in volumes and folders, apply tags and retention policies. Governance rules attach automatically by classification.
Share internally with granular permissions, or externally with expiring, password-protected, revocable links — every share is logged.
Every action lands in a tamper-evident audit trail — who, what, when, and from where — exportable to your SIEM and regulators.
Storage, sharing, identity, compliance, and administration — unified in a single multi-tenant platform.
Internal permission-based sharing that inherits through folders, plus public links that stay under your command.
SHARE LINK

Sometimes the file needs to come to you. SecureShare's Inbox generates a request link any external party can use to send files directly into your encrypted storage.
Federated SSO, multi-factor authentication, and a granular RBAC model with hierarchical access control lists.
SecureShare pairs its encryption and compliance core with the organizational tools teams expect — so locking files down never means losing track of them.
Fast, per-tenant search across your files — encryption never makes anything harder to find.
No caps on upload size — move multi-gigabyte files without splitting or workarounds.
Top-level storage spaces with their own access control, quota, and retention — plus folders, tags, and favorites.
Deletions are recoverable from a per-volume trash until they're purged.
In-app and email alerts on uploads, downloads, shares, and security events — with per-category preferences.
User- and tenant-scoped contacts and groups make recurring sharing and upload requests fast.
Uploads and downloads are chunked and resumable — large files survive flaky connections — and everything runs in a modern browser with no client software to install.
Files are encrypted with XChaCha20-Poly1305 authenticated encryption; password keys are derived with Argon2id. Each organization — and each file — matches the model to the sensitivity of the data.
Files are encrypted automatically at rest under a per-tenant key hierarchy. Frictionless for users, strong at-rest protection for admins. Ideal for general business data.
When a password is set, the file is encrypted in the browser before it ever reaches the server. The platform stores only ciphertext and never sees the password or plaintext — true zero-knowledge confidentiality, with an optional administrative recovery path. Ideal for your most sensitive material.
A layered hierarchy limits the blast radius of any single exposure and enables rotation without re-encrypting data wholesale.
Retention, immutability, legal hold, and a tamper-evident audit trail — technical controls that support your compliance and legal workflows.
Automated classification rules, event-based disposition, and human review & approval before deletion.
Governance and compliance modes for unalterable, long-term record-keeping — pair with S3 Object Lock.
Freeze files for litigation — retention clock stops, deletion blocked, every action recorded with reason and approver.
Cryptographic integrity checkpoints, SIEM webhooks, ClickHouse analytics, and configurable long-term retention.
Strict isolation per tenant, and a complete administrative toolset — equally suited to a single enterprise, a managed service provider, or a SaaS offering.
Every tenant's data, keys, users, and configuration are isolated. Tenants are resolved by domain, each has its own cryptographic key hierarchy, and access is filtered by tenant at every layer.
Delivered as containers that validate their security-critical configuration at startup. Deploy as managed SaaS or inside your own infrastructure — down to fully disconnected networks.
Managed by BlackShield. Nothing to run — the quickest path to production.
Deploy in your own cloud or data center for full data control and residency.
Runs in isolated, disconnected environments with no external dependencies.
S3-compatible object storage or local filesystem — selectable per tenant.
Master key from an environment secret, AWS KMS, or OpenBao (Vault-compatible).
No client software to install. Any modern web browser is all users need.
For organizations that must share sensitive data and prove control, visibility, and retention.
Store and share sensitive healthcare documents with strong encryption, full audit trails, and access controls that support GDPR obligations for sensitive health data.
Safeguard statements, disclosures, and case files with per-tenant key isolation, tamper-evident audit, and long-term record retention.
Share client files and discovery securely — granular permissions, instant revocation, and a complete chain-of-custody audit trail.
Air-gapped deployment, strict tenant isolation, and federated identity for sensitive public-sector data.
Encryption, control, and compliance that organizations usually assemble from separate products — unified, under one audit trail, with one set of keys you control.
