Security architecture

Your documents are stored in Sydney, under Australian privacy law.

The Vukorix production application, its database, and every uploaded file run in the DigitalOcean Sydney (SYD1) region. Vukorix is operated by Osmicro Networks Pty Ltd, an Australian company registered in New South Wales, and personal information is handled under the Privacy Act 1988 (Cth) and the Australian Privacy Principles.

Some sub-processors do work offshore, including Google Analytics for aggregated website analytics and the transactional email provider that sends operational email. Those are cross-border disclosures under Australian Privacy Principle 8, and every sub-processor is listed with its purpose and location in the Privacy Policy. Vukorix does not claim that no data ever leaves Australia.

The rest of this page is a technical overview for security, risk, and procurement teams: trust boundaries, encryption, access control, product processing, monitoring, and recovery, along with the controls Vukorix does not claim to have.

Architecture

Layered protection, with storage and product processing in Sydney.

Vukorix separates the client and recipient experience, product processing, stored data, and service operations into distinct security responsibilities. The application, database, and uploaded files all sit in Sydney (SYD1), and requests reach that region through the Cloudflare edge described below.

Client and recipient boundary

Authentication, access controls, and browser security

Users authenticate to their organisation account. Recipients use controlled links and any required PIN, password, SMS code, expiry, or view limit. Private mode encryption begins in the sender's browser for supported file transfers. Cloudflare fronts the Vukorix domains for DNS and edge protection; it is not where your documents are stored.

Application and control layer

Product logic, permissions, and required document processing

Vukorix applies account access rules, recipient controls, product processing, status updates, and relevant event recording. Standard-processing features can access file contents only where the selected product requires it.

Data and operations layer

Encrypted storage in Sydney, monitoring, backups, and recovery

Stored content is encrypted and held in the Sydney (SYD1) region, alongside the production application and database. Operational access is restricted, monitoring and alerts run continuously, and backups and recovery procedures are maintained.

Primary trust boundaries

  • The Sydney (SYD1) region, where the application, database, and uploaded files sit
  • Organisation accounts and authorised team access
  • Recipient links and optional access checks
  • Vukorix systems performing required product processing
  • Private mode file contents encrypted before reaching Vukorix systems

The security model differs according to the product feature being used. Features that need document preparation, previews, signing, forms, or messaging require secure server processing. Supported Private mode transfers keep file contents outside the Vukorix processing boundary.

Cryptography

Two document-protection paths, selected by the product feature.

Standard secure processing supports product features that need access to document contents. Private mode moves supported file encryption into the sender's browser.

AreaStandard secure processingPrivate mode
Where content is storedSydney (SYD1), in the same region as the application and database.Sydney (SYD1), stored as ciphertext.
Where encryption beginsThe connection between the browser and Vukorix is encrypted.The file is encrypted in the sender's browser before upload.
Stored contentStored file content is protected using AES-256-GCM with a Vukorix-managed key.Vukorix stores encrypted file data and does not have access to the file contents.
Content processingAuthorised Vukorix systems can process document contents where required by the selected product feature.Vukorix systems do not decrypt the supported file contents.
Feature supportE-Sign, Smart Forms, Document Library, previews, redaction, and Secure Exchange messaging.Secure Share, Secure Receive, and supported Secure Exchange file transfers.
RecoveryContent remains available through the organisation's authenticated account while retained by the service.Vukorix cannot recover file contents if the required link information or passphrase is lost.
MetadataAccount, recipient, product, and event information may be recorded according to the selected feature.File contents are protected, but operational metadata may still be retained.
Private mode metadata and recovery details

Private mode protects supported file contents but does not remove all service metadata. Vukorix may retain sender identity, timestamps, file size, and ciphertext integrity information needed to operate and secure the service.

Recipient IP address and user-agent information are not retained on Private mode events.

Filenames can be hidden where the selected product supports that option.

The required decryption information may depend on the share link or passphrase. If it is lost, Vukorix cannot recover the file contents.

Identity and access

Controls for accounts, recipients, and operational access.

Organisation accounts

  • Two-factor authentication is required for Vukorix accounts
  • WebAuthn passkeys and authenticator apps are supported
  • Supported sign-in methods include Google, Microsoft, and email/password
  • Organisation content is available only through authenticated account access

Recipient access

  • Controlled links can use expiry dates and view limits
  • Supported products can require a PIN, password, or SMS code (SMS is sent to Australian mobile numbers only)
  • Recipient access checks add another access step
  • These controls do not independently verify a person's legal identity

Operational access

  • Staff access is restricted to authorised operational, support, security, and legal purposes
  • Access is limited to the circumstances required to operate and support the service
  • Detailed infrastructure credentials and configuration are not published publicly
Event records and outputs

Records produced by document activity.

Vukorix records relevant account and product events and provides product-specific completion records.

E-Sign records

Completed E-Sign documents include the signed PDF, a certificate page, and a separate audit-pack PDF.

  • Signer and recipient information
  • Timestamp
  • IP address
  • Geolocation where available
  • Signature method
  • Recorded signing events

Secure Exchange records

Completed Secure Exchange items can include a completion certificate and audit pack.

Important limitation

Vukorix does not publicly claim that event records are append-only, HMAC-chained, or independently tamper-proof unless those controls are separately verified.

Manual PDF redaction

Manual PDF Redaction is available inside the E-Sign and Smart Forms editors. The selected page is rasterised, opaque areas are applied, and the exported page is produced as an image-based copy.

The underlying PDF text is removed from the selected area in the exported copy. The document owner retains the original source document.

Operations and resilience

How Vukorix is operated and maintained.

  1. Australian data residency

    The production application, its database, and uploaded files all run in the DigitalOcean Sydney (SYD1) region. Cloudflare fronts the Vukorix domains for DNS and edge protection. The providers that host the service maintain recognised information-security certifications, such as ISO 27001; those certifications belong to the providers, not to Vukorix. Account identifiers, credentials, and internal network topology are not published on this page.

  2. Continuous monitoring

    Automated monitoring and alerts run around the clock to help identify and investigate operational issues.

  3. Backups and recovery

    Backups and recovery procedures are maintained as part of normal service operations.

  4. Tested releases

    Changes are tested before release, with security and reliability reviewed as the service evolves.

  5. Incident investigation

    When monitoring identifies an issue, Vukorix investigates it, uses available recovery procedures where needed, and applies what is learned to improve the service.

  6. Restricted administration

    Administrative access is limited to authorised purposes and is not exposed through the public customer experience.

Data governance

Content, metadata, retention, and cross-border disclosure.

Customer Content

Customer Content is stored in the Sydney (SYD1) region and handled according to the selected product and encryption path. Standard-processing features can access file contents where required. Private mode protects supported file contents from Vukorix access.

Operational metadata

Vukorix retains the account, product, event, and technical information required to operate, secure, and support the service. That account, product, and event metadata is held in the same Sydney region as the documents it relates to. Aggregated website analytics data and operational email delivery records sit with the overseas sub-processors described below.

Retention and breach notification

Retention and deletion are governed by the published Privacy Policy and the controls available in the selected product. The Notifiable Data Breaches scheme under the Privacy Act 1988 (Cth) applies to eligible data breaches. This page does not publish unverified per-product or backup-deletion timelines.

Cross-border disclosure and APP 8

Your documents and account data are stored in Sydney. Some sub-processors work offshore, including Google Analytics for aggregated website analytics and the transactional email provider that delivers operational email. Those are disclosures to overseas recipients under Australian Privacy Principle 8, and every sub-processor is listed with its purpose and location in the Privacy Policy. Vukorix does not claim that no data ever leaves Australia.

Secure development

Security review continues as the product evolves.

Design review

Security and privacy are considered when product behaviour and data handling are designed.

Release testing

Changes are tested before release, with security and reliability included in the review.

Continuous improvement

Vukorix reviews technical changes, customer feedback, operational events, and recognised security practices to improve the service.

Vukorix reviews its security design and operations against recognised security and privacy guidance, including the Australian Privacy Principles. This is not a claim of certification, formal conformance, or independent assurance.

Assurance and limitations

Current security assurance status.

Vukorix is not currently SOC 2 certified and has not completed an independent external cryptographic audit.

Vukorix is not ISO 27001 certified. Recognised information-security certifications, such as ISO 27001, are maintained by the providers that host the service, and those certifications belong to the providers rather than to Vukorix.

Vukorix has not been assessed under the Information Security Registered Assessors Program (IRAP), holds no Australian Government security accreditation, and makes no claim of alignment with the ACSC Essential Eight.

Vukorix does not claim that every product uses browser-side encryption, that every event record is independently tamper-proof, or that any online service can guarantee complete security.

This page will be updated as controls are independently reviewed and additional assurance becomes available.
