Secure-by-design architecture
Security architecture and solution-design oversight across distributed systems and integrations.
Security built into architecture and decisions
Security Architecture
Design security as part of the solution, not as a control added after implementation.
I help organisations connect security risks, regulatory expectations and business continuity with practical architecture decisions across systems, data and integrations.
Business contextSecure design
Protection aligned with purpose
What Security Architecture Is
Security architecture translates business risks, regulatory obligations and technical realities into a coherent design for systems, integrations and data.
It defines how security principles and controls work together across the solution lifecycle from identity and access to cryptography, data flows, suppliers, documentation and operational resilience.
The objective is a secure-by-design solution that remains understandable, traceable and practical for engineering and operational teams.
Security from governance to implementation
How I Can Help
Governance and compliance
Policies, procedures, traceability and audit readiness aligned with regulatory frameworks, including DORA.
Data protection and cryptography
Protection of data at rest and in transit, cryptographic controls, keys, certificates and data lifecycle considerations.
Identity and access
SSO, IAM and security integrations across internal platforms and SaaS ecosystems.
Third-party risk
Security requirements, vendor discussions, solution assessment and assurance of data flows.
Operational resilience
Incident readiness and security measures aligned with business continuity objectives, including RTO and RPO.
Evidence before assumptions
How I Work
Security decisions begin with understanding the business, the existing environment and the data that needs protection.
- 01
Understand the business context
Clarify objectives, critical services, stakeholders and continuity needs.
- 02
Investigate the current state
Map systems, integrations, data flows, assets and existing security controls.
- 03
Identify risks and obligations
Connect technical findings with regulatory, audit and business requirements.
- 04
Evaluate security options
Challenge assumptions and compare controls against technical feasibility and operational impact.
- 05
Define the security design
Turn decisions into architecture, requirements and implementation guidance.
- 06
Document and establish traceability
Create clear records that support engineering, governance and audit readiness.
- 07
Guide implementation
Support system owners and engineering teams as security controls are delivered.
