Enterprise-level electronic document management

SYNTERRA EDO PRO — next-generation electronic document management

Legally significant signatures. Tamper-proof audit. Crypto-sealing. Integrations with banks and eGov.

Electronic document management for companies with heightened requirements for security, transparency, and fault tolerance. SYNTERRA EDO PRO combines digital signatures/QES, approval workflows, archive, external signing, and a unique tamper-proof audit (hash‑chain + Merkle + anchoring), ensuring legal enforceability of actions.

What is this

Corporate EDI system with legal force

SYNTERRA EDO PRO is not just 'sign a PDF.' It is a secure platform for managing documents within a company and with external counterparties — with legally binding signatures, integrity control, and a verifiable audit trail.

  • Legally significant signature (EDS/QES), multi-signature, timestamp, OCSP/CRL verification.
  • External signing via guest portal and one-time secure links with TTL.
  • Integrations with NCA RK, eGov API, banking gateways and corporate systems (SAP/1C/Oracle).
  • Document repository: versions, archive, search, WORM mode, and access control (RBAC/ACL).
  • Tamper-proof audit: hash chain + Merkle intervals + anchoring (WORM / Object Lock / external notary).
  • Secured inter-organizational exchange and audit of every operation.

The solution is aimed at bank-grade information security, corporate policies, and public sector requirements (KZ).

Key capabilities

SYNTERRA EDO PRO functions

If you are looking for electronic document management for a corporation, bank, or government body in Kazakhstan — SYNTERRA EDO PRO covers signatures, routing, archiving, and action provability (tamper-proof audit)

: 1) Signing documents with EDS/QES

  • CMS / CAdES / XAdES.
  • NCA RK Certificates.
  • Check status: OCSP / CRL.
  • Multi-signature, timestamp (TSA) according to policy.
  • Signature on the client side and server side (depending on the circuit).
  • Support for HSM and KMS (if necessary).

2) External signatures via a one-time secure link

  • Unique token with TTL, one-time access.
  • Click → guest signing portal.
  • Step‑up: OTP / email‑verify / digital signature.
  • Fixation of IP / user-agent / result (according to policy), full audit trail.
  • Legal significance in intercompany exchange (in the EDS/QES mode).

3) Branch Integrity (crypto-sealing of branch markers)

  • Level 0: internal stamp (inside the system only).
  • Level 1: crypto-tag (HMAC-SHA-256) when exporting outside.
  • Mandatory upgrade to Level 1 during external export.
  • Fail-closed: if the tag is not created — export is blocked.
  • One‑click verification of the integrity tag by ID/version.

4) Tamper‑Proof Audit (unique advantage)

  • Event hash‑chain (tampering breaks the entire chain).
  • Merkle intervals and Merkle proof for independent verification.
  • Anchoring: WORM / S3 Object Lock / external anchoring (optional).
  • Online check: /audit/{id}/verify.
  • Offline proof: /audit/{id}/proof.
Such an audit is used by top vendors: it makes the 'cleanup' of actions detectable and verifiable.

5) Workflow engine (routing)

  • Sequential and parallel routes.
  • Conditional transitions ('if the amount is greater...')
  • Roles: approvers, signatories, observers.
  • Task Panel, Comments, Versions, Attachments

6) Document storage

  • Versions, archive, search.
  • OCR (optional by configuration).
  • WORM mode and retention policy.
  • Access control and operation log

7) Integrations

  • NCA RK, eGov API.
  • SAP, 1C, Oracle.
  • Postal and banking gateways.
  • KISC (optional).

Security / DLP / Compliance

Corporate and banking-level security

Tamper‑Proof Audit

Hash‑chain + Merkle + anchoring — verifiable tamper-proof audit trail.

Crypto-Tag on export

Branch integrity tag protects branch marks; forgery "outside the system" is detected.

Fail-closed policy

If a crypto‑tag cannot be generated — export is blocked (without compromises).

Vault / KMS / HSM

Key storage, rotation, access control; HSM support (optional).

Access Control

RBAC/ACL, role separation, audit of every operation attempt.

DLP and Watermark

Watermarks, user marks, restriction on exporting confidential data (according to policy).
Signatures

Legally significant signing and provability

SYNTERRA EDO PRO supports legally significant signatures EDS/QES and distinguishes them from operational "stamps." Any action is recorded in a tamper-proof audit and can be verified.

  • Digital signature/QES signatures according to CMS/CAdES/XAdES, trust verification (OCSP/CRL), timestamp
  • Legal force of actions thanks to a verifiable audit trail.
  • External signing: the counterparty signs without registration — via the guest portal.
  • Branch marks: non-legal vs legal; the crypto-tag protects against falsification during export.
  • Full audit trail: date, author, certificate, chain of trust, verification result.
