Security Architecture
Design and independently review systems against Australian Government frameworks and operational requirements.
We evaluate existing architectures and design new solutions aligned with Australian Government frameworks and operational requirements. Whether you are modernising legacy infrastructure or designing a greenfield system, we provide independent assurance that security is built in — not bolted on.
When To Engage Us
- New systems and major transformation programs
- Teams modernising legacy or high-value environments
- Programs requiring independent design assurance
What We Cover
- Trust boundaries and system segregation
- Identity and access management
- Encryption and key-management patterns
- Cloud, integration, and supply-chain risk
Clear Outputs
Typical Engagement Outputs
Final outputs are agreed during scoping so they support the decisions your team needs to make.
- Architecture findings and risk narrative
- Practical design recommendations
- Control and framework alignment
- Stakeholder walkthrough and decision support
Define The Right Boundary
How We Scope It
A useful engagement begins with a clear assurance question. For this service, scoping normally considers:
- The business capability, critical information, and operational outcomes the system supports
- Architecture maturity, available diagrams, design decisions, and known constraints
- Applicable frameworks, security classifications, assurance gates, and risk tolerances
- Key integrations, identity providers, trust boundaries, suppliers, and inherited controls
From Question To Uplift
How We Work
The approach is adapted to your environment, while keeping communication, evidence handling, and decision points clear.
Establish Context
Understand the mission, information, users, threats, constraints, and assurance obligations that shape the design.
Model Trust
Map components, data flows, identities, boundaries, dependencies, and the assumptions holding the design together.
Challenge The Design
Review control choices, failure modes, attack paths, and operational trade-offs against the required outcomes.
Guide Decisions
Document material risks and practical recommendations so architects and decision-makers can move forward confidently.
Common Questions
Before You Engage
Can you review an architecture that is still being designed?
Yes. Early review is often the most valuable because important trust, identity, segregation, and integration decisions can still be changed without expensive rework.
Do you only work with Australian Government systems?
No. We apply the same structured reasoning to government, defence, critical-infrastructure, regulated, and enterprise environments, using the frameworks relevant to each organisation.
What documentation is needed to begin?
Current diagrams, data flows, requirements, risk material, and key design decisions are useful, but imperfect documentation is not a blocker. Establishing an accurate current view can be part of the engagement.
