Dynamic Authorisation & Access Control
Deliver context-aware authorisation and granular access controls based on identity, behaviour, risk, and environmental signals.
Authorisation Built for Real-World Context
Authentication answers the question: who are you? Authorisation answers the harder question: what are you allowed to do, with what data, under what conditions, right now? Traditional role-based access control was designed for simpler times: static roles, predictable access patterns, and limited application complexity. Dynamic Authorisation replaces this with real-time, context-aware access decisions that reflect the actual risk, intent, and legitimacy of every request.
Understanding the enterprise challenges
Access decisions cannot be justified during audits
Role and responsibility changes leave entitlements misaligned
Compliance violations go undetected until reviews or incidents
Accountability breaks down across distributed systems
Why This Matters
Coarse-grained access control is a hidden liability in most enterprises. Users accumulate roles that grant far more access than their current task requires. Access policies are embedded in application code, making them expensive to change and impossible to audit centrally. API ecosystems expose sensitive data and operations without granular controls. Open Banking and regulated data-sharing mandates demand consent-driven, fine-grained authorisation that legacy RBAC cannot deliver. The gap between what users are authorised to do and what they should be authorised to do is where risk lives.
The Trevonix Approach
Trevonix designs and implements dynamic authorisation architectures that externalise access policy from applications, enabling centralised, real-time authorisation decisions that are consistent, auditable, and fast to update. We implement Fine-Grained Authorisation using industry standards including XACML, OPA, and Cedar, and design Open Banking authorisation flows meeting PSD2 and regulatory consent requirements. Our external authorisation service approach decouples policy from code — meaning new access models can be deployed without application changes.

Precise, Resource-Level Access Control Across the Enterprise
- Attribute and policy-based access control down to resource, action, and context level
- Centralised entitlement store replacing dozens of siloed permission models across product lines
- Policy externalisation enabling access model changes without application code deployment
- Real-time authorisation decisions with automated audit trail for compliance reporting

Consent-Driven Authorisation for Regulated Data Sharing
- OAuth 2.0 and consent-based authorisation for PSD2 and Open Banking compliance
- Fine-grained API authorisation controlling access to specific data types and operations
- Third-party provider (TPP) access governance with dynamic consent management
- Audit-ready authorisation logs meeting FCA, PRA, and Open Banking regulatory requirements

Dynamic Access Decisions Based on Business Rules and Context
- Access policies defined in terms of business rules, user attributes, and environmental context
- Adaptive policy enforcement responding to risk signals, device posture, and data sensitivity
- Centralised policy management enabling consistent enforcement across all applications
- Rapid policy iteration reducing time-to-market for new access models and products

Decoupling Authorisation Logic from Applications
- Centralised Policy Decision Point (PDP) serving authorisation decisions to all applications
- Standardised authosization API enabling consistent access control across the estate
- Reduced application complexity and development overhead through shared authorisation logic
- Enterprise-wide authorisation visibility and governance from a single control plane
