Security & data-handling dossier

How the CERTE governance platform protects customer data: our security architecture, encryption and data-handling practices, compliance approach, and the controls behind the product. Prepared for procurement, risk, and audit teams.

CERTE is a governance, risk, and continuity platform hosted entirely within Australia. We hold platform data to a least-privilege, encrypted-by-default standard. Detailed assessment findings and our remediation roadmap are available to verified stakeholders.

Security Architecture

Defence in depth — how CERTE is built

CERTE applies layered controls across infrastructure, data, identity, and application. The description below reflects the platform as actually deployed.

LAYER 01INFRASTRUCTURE

Infrastructure

Hosted in AWS Sydney (ap-southeast-2) on Amazon Linux 2023 with Alpine-based Docker containers. Weekly OS patching is applied to the underlying platform.

AWSEC2Dockerap-southeast-2
LAYER 02ENCRYPTED

Data Protection

AES-256-GCM at rest via AWS KMS across database storage, backups, and S3 report files. TLS in transit with TLS 1.0/1.1 disabled at the load balancer.

AES-256-GCMAWS KMSTLS 1.2+S3
LAYER 03ENFORCED

Identity & Access

Administrative and staff access uses IAM least-privilege with enforced MFA (passkey/TOTP/FIDO; SMS disabled). Database access is brokered through a bastion/proxy rather than exposed directly.

IAMMFABastion brokerRBAC
LAYER 04SECURE SDLC

Application

NestJS + Apollo GraphQL backend and a Next.js frontend. Passwords are hashed with bcrypt, ORM queries are parameterised, and dependencies are scanned with Snyk during development.

LAYER 05MONITORED

Logging & Privacy

Activity is logged to AWS CloudWatch with sensitive fields redacted. Critical user actions are recorded against unique IDs to maintain an auditable timeline.

LAYER 06RESILIENT

Backup & Retention

Encrypted daily database backups are retained in AWS. Generated report files (PDFs) are automatically purged after 7 days to limit data exposure.

Identity & Access

Built for enterprise identity

Certe protects access with phishing-resistant multi-factor authentication on privileged accounts, role-based access control over every document, and encrypted credential storage.

Available today
  • Phishing-resistant MFA on privileged accessAdmin and infrastructure access enforces passkey / TOTP MFA via IAM. SMS and email codes are disabled.
  • Role-based access controlIn-platform roles — owner, collaborator, viewer — scope access to every document.
  • Encrypted credential storagePasswords are hashed with bcrypt; no credentials are stored in plaintext.

Data Handling & Residency

What we hold, and where it lives

CERTE is a self-reporting governance and risk tool. We design to minimise the personal information held and to keep customer data within Australia.

Primary dataBusiness-confidential governance & risk content
Personal informationMinimal — stakeholder names & email addresses
Not collected by designNo health records · no payment-card data stored on platform
ResidencyAWS Sydney — no overseas transfer without consent
At restAES-256-GCM (AWS KMS)
Report retentionGenerated PDFs purged after 7 days

Free-text fields may contain organisationally sensitive material; access is restricted to invited document owners, collaborators, and viewers.

Compliance & Assurance Approach

Standards, frameworks & status

The frameworks below reflect CERTE’s control posture as it stands today — what is enforced, aligned, and independently reviewed. We reference recognised standards and describe our practices accurately, without overstating certification.

Aligned

Australian Privacy Act 1988 (APPs)

Data handling aligned to the 13 Australian Privacy Principles, including the Notifiable Data Breach scheme. The platform is designed to minimise personal information.

APP alignedAU-hosted
Enforced

Data Residency — Australia

All platform data is hosted in the AWS Sydney region. Personal information is not transferred overseas without explicit consent.

AWS ap-southeast-2No overseas transfer
