Trust Surface Framework Map
The Trust Surface Framework (TSF) provides a structured model for understanding how digital systems influence stakeholder trust.
The framework connects four key elements:
- Trust Surface – where digital trust is experienced
- Trust Signals – observable indicators of trust posture
- Trust Lifecycle – how organisations manage digital trust
- Governance Integration – how trust becomes part of organisational oversight
Together, these elements help organisations understand and manage their Digital Trust Posture.

This model illustrates how organisations move from identifying their digital systems to governing their digital trust posture.
Trust Surface Domains
The Trust Surface represents the digital systems through which stakeholders experience an organisation’s digital presence.
The framework identifies six primary domains.
| Domain | Description |
|---|---|
| Identity | Authentication and identity systems |
| Domains & DNS | Domain ownership and DNS infrastructure |
| Email Integrity | Authenticity of organisational email communications |
| Digital Services | Websites, applications, and online platforms |
| Infrastructure & Platforms | Technical environments supporting services |
| Third-Party Ecosystem | External vendors and SaaS platforms |
These domains collectively form the organisation’s digital edge.
Trust Signals
Each Trust Surface domain emits observable signals that indicate how well digital systems are governed.
Examples include:
- SPF, DKIM, and DMARC email authentication
- DNS configuration and DNSSEC adoption
- TLS encryption and certificate hygiene
- service reliability indicators
- vendor security attestations
These signals allow organisations to measure digital trust posture objectively.
Trust Signal Scorecard
Signals are evaluated using a maturity model.
Example:
| Domain | Maturity |
|---|---|
| Identity | Level 3 |
| Domains & DNS | Level 4 |
| Email Integrity | Level 2 |
| Digital Services | Level 3 |
| Infrastructure | Level 2 |
| Third-Party | Level 1 |
The scorecard provides an overview of the organisation’s Digital Trust Posture.
Trust Surface Lifecycle
The framework defines a continuous lifecycle for governing digital trust.
Discover → Assess → Harden → Govern → Signal
Discover
Identify the systems that make up the Trust Surface.
Assess
Evaluate systems using the Trust Signal Catalogue.
Harden
Strengthen weak or inconsistent trust signals.
Govern
Integrate trust signals into governance and risk management.
Signal
Communicate trust posture to stakeholders.
The lifecycle repeats as digital systems evolve.
Relationship to Governance
The Trust Surface Framework complements existing governance and cybersecurity practices.
It provides a mechanism for translating technical signals into governance insights.
This allows executives and boards to better understand:
- where digital trust risks exist
- how well trust signals are maintained
- how trust failures might affect reputation and operations
Framework Components
The Trust Surface Framework currently includes the following documents.
| Document | Purpose |
|---|---|
| Digital Trust Problem | Explains why digital trust needs structured governance |
| Trust Principles | Foundational principles guiding the framework |
| Trust Surface Definition | Defines the concept of a Trust Surface |
| Trust Surface Map | Describes the six Trust Surface domains |
| Trust Signal Catalogue | Lists measurable trust signals |
| Trust Surface Lifecycle | Explains how organisations manage digital trust |
Together these components form Trust Surface Framework v0.1.
Status
This framework is currently published as a draft for consultation.
The model may evolve as organisations explore practical ways to measure and govern digital trust.
