A zero-knowledge enterprise data vault. Files are encrypted before storage, keys stay with you, and every access is cryptographically enforced — not operationally trusted.
eVaultz is built on four non-negotiable principles. Each one is a cryptographic guarantee — not a marketing claim.
Files are encrypted at the client before they leave your device. Plaintext data never touches eVaultz infrastructure — not during upload, not at rest, not ever.
Encryption keys are generated and controlled exclusively by you. eVaultz has no technical ability to view, decrypt, or access your data — by construction, not by policy.
Permissions, sharing, and revocation are enforced through cryptography — not access-control lists. If a key is revoked, the data is mathematically inaccessible.
Every access event, permission change, and administrative action is immutably logged. Export audit trails for SOC 2, ISO 27001, GDPR, or internal reviews — always ready.
Trust boundary guarantee
At no point does eVaultz have access to unencrypted data or the keys required to decrypt it — by design.
Most cloud storage leaves sensitive data exposed. eVaultz changes that equation — cryptographically, not operationally.
Human-readable
Anyone with access can read your data
Plaintext at rest
Exposed via backups, snapshots & logs
Breach-ready
Easy to copy, exfiltrate or ransom
No revocation
Shared access persists indefinitely

Zero-Trust Policy — your secrets stay safe even if infrastructure fails.
eVaultz is built on a zero-knowledge security architecture where encryption, key ownership, and access control are enforced cryptographically — not operationally.
Client-Side Encryption
01Files are encrypted at the client before upload. Plaintext data never reaches eVaultz servers — encryption is a client responsibility by design.
Customer-Controlled Keys
02Encryption keys are generated and controlled exclusively by the customer. eVaultz has zero access to decryption keys — under any operational condition.
Isolated Storage Layer
03Encrypted data is stored in tenant-isolated storage systems. No component of the storage layer has access to plaintext or encryption keys.
Audit & Control Plane
04All access, sharing, and administrative actions are logged immutably. Every event includes actor identity, timestamp, resource, and outcome.
Trust Boundary
At no point does eVaultz have access to unencrypted customer data or the keys required to decrypt it — by architecture, not just policy.
A continuous encryption lifecycle — from upload to secure delivery — without ever exposing plaintext or encryption keys.

Customer-controlled encryption keys — never accessible by eVaultz
Every upload, view, and access is immutably logged
Zero-knowledge enforced across upload, storage, and viewing
Every threat is neutralized by cryptographic guarantees — not operational assumptions. Even a full infrastructure compromise cannot expose your data.
Encrypted data remains unreadable without access to customer-held encryption keys. A breach of our infrastructure yields only ciphertext.
01Zero-knowledge architecture prevents employees from viewing or decrypting customer data — access is cryptographically blocked, not just policy-blocked.
02Cryptographic access controls, instant revocation, and immutable audit logs limit blast radius. Compromised credentials cannot yield unencrypted data.
03All shared access is time-bound and can be revoked instantly at the key level. Every access attempt is logged with actor, timestamp, and result.
04Security Guarantee
Even in the event of a full infrastructure compromise, attackers cannot decrypt customer data without access to customer-controlled encryption keys. Zero-knowledge is architecture — not a policy.
Every access decision in eVaultz is explicit, cryptographically enforced, and immutably logged — giving teams full control and continuous audit readiness without extra tooling.
Explore the security modelAccess flow
Every request passes identity verification → policy evaluation → cryptographic authorization → vault access → immutable log entry.
Role-Based Access
Define exactly who can view, upload, share, or revoke access — per file, folder, or org unit.
Cryptographic Enforcement
Permissions enforced through encryption keys, not application logic. Bypass is mathematically impossible.
Time-Bound Access
Access expires automatically on a schedule and can be revoked instantly at any time.
Immutable Audit Logs
Every access, change, and admin action is logged with actor, timestamp, and outcome — exportable.
Built to support SOC 2, ISO 27001, and GDPR with immutable, exportable audit logs.
eVaultz is built to align with globally recognised security and privacy frameworks — supporting audits, regulatory requirements, and enterprise governance.

Talk to usEncryption is only as strong as the keys behind it. eVaultz is built on a cryptography-first architecture where key ownership, isolation, and lifecycle control are non-negotiable.
Core Guarantees
Strong encryption by default
All data is encrypted using AES-256-GCM. Encryption is automatic, enforced, and cannot be disabled by any user or admin.
Unique keys per tenant
Every organisation operates with isolated encryption keys, ensuring strict cryptographic separation between tenants.
Zero access to keys
eVaultz never stores, exports, or accesses customer encryption keys in plaintext — under any circumstances, by design.
Operational Controls
HSM & external KMS ready
Integrates with hardware-backed key management systems and external KMS platforms for regulated environments.
Key rotation & lifecycle
Supports secure rotation, revocation, and lifecycle management aligned with enterprise security and compliance policies.
Hold Your Own Key (HYOK)
Decryption occurs exclusively within customer-managed infrastructure, ensuring complete cryptographic isolation from eVaultz.
Cryptographic operations are designed to support separation of duties, external key ownership, and compliance-driven encryption requirements — aligned with enterprise security models and industry standards.
Data moves through deterministic, cryptographically enforced states — never leaving its trust boundary. Every stage is auditable, reversible, and under your control.
Secure Upload
In Transit · TLS Encrypted
Data is accepted exclusively over encrypted transport (TLS 1.3). Plaintext is never written to disk during ingestion — validation and processing happen in-memory only.
Immediate Encryption
Encrypted · Keys Isolated
Immediately after ingestion, data is encrypted using tenant-isolated cryptographic keys (AES-256-GCM). Encryption is automatic, enforced, and cannot be bypassed by any user or admin.
Encrypted Storage
At Rest · Ciphertext Only
Only encrypted data is persisted at rest. Plaintext is never stored in databases, object storage, backups, or snapshots — at any layer of the infrastructure.
Controlled Access
Decrypt-in-Use · Policy Gated
Decryption occurs only in-memory and only after identity verification, policy evaluation, and cryptographic authorization checks are fully satisfied.
Secure Sharing
Delegated · Time-Bound
Data sharing occurs through delegated, time-bound access with fine-grained permissions. Every access attempt is logged with actor, timestamp, and outcome.
Revoke & Delete
Revoked · Cryptographically Destroyed
Access can be revoked instantly at the key level. Encrypted data is securely deleted per retention policies — rendering it permanently and cryptographically inaccessible.
At no point in the lifecycle does eVaultz persist unencrypted data or expose encryption keys beyond their defined trust boundaries.
