Security Architecture
& Design
Security is far cheaper to design in than to bolt on later. We work alongside your IT and engineering teams to build it into the architecture from the start, whether that's a greenfield build, a cloud migration, or uplifting a legacy environment that grew without a plan.
- Full-scope security architecture for new systems and infrastructure - design through to documentation
- Legacy environment security uplift and modernisation planning
- Cloud security architecture for AWS, Azure, GCP, and hybrid environments
- Network segmentation, firewall policy review, and DMZ design
- Secure software development lifecycle (SSDLC) consulting
- Threat modelling and architecture risk assessments
- Reference architecture development aligned to ACSC ISM controls
- Cryptography, PKI, and key management advisory
Common Questions
When should security architecture get involved in a project?
Before anything is built. Security designed in costs a fraction of security bolted on, and it doesn't arrive with the delays and friction of late-stage rework.
What is threat modelling?
A structured exercise that asks: what are we building, what can go wrong, and what are we doing about it - before an attacker asks the same questions. It's the highest-value hour you can spend on a new system's security.
What standards do you design against?
The ACSC ISM for government-aligned environments, NIST SP 800-53, SABSA, and cloud provider well-architected frameworks - matched to what your organisation is actually measured against.
