Solutions & Architectures

This section documents how security, compliance, and resilience are implemented in practice across cloud platforms, software delivery pipelines, and operating models.

The focus is on execution, not abstract frameworks.

Purpose of this section

The Solutions & Architectures section exists to answer a single question:

How do regulated organisations actually implement security and compliance controls in modern, vendor-hosted environments?

It covers:

  • Secure software delivery patterns

  • Vulnerability and supply-chain governance

  • Cloud security foundations and shared responsibility

  • Detection, response, and monitoring architectures

  • Container and Kubernetes security models

What these solutions are designed to achieve

All architectures documented here aim to:

  • Translate regulatory and customer requirements into technical controls

  • Produce continuous, audit-ready evidence

  • Support engineering speed rather than slow it down

  • Create defensible positions for audits, tenders, and customer reviews

  • Clarify ownership in vendor-hosted and shared-responsibility environments

How to use this section

Use these documents as:

  • Reference architectures when designing or reviewing systems

  • Implementation guidance for engineering and platform teams

  • Assurance support during audits, tenders, and customer assessments

  • Alignment material between security, compliance, and engineering teams

Each solution page is self-contained and can be read independently.

Scope and assumptions

Unless stated otherwise, the solutions documented here assume:

  • Cloud-hosted or vendor-managed infrastructure (e.g. AWS, managed services)

  • CI/CD-driven software delivery

  • Multiple teams contributing to a shared product or platform

  • Regulatory or customer-driven security requirements

These solutions are tool-agnostic by design. Specific technologies are referenced only to illustrate implementation patterns, not to mandate products.

Relationship to Compliance Mapping

This section focuses on how controls are built.

The Compliance Mapping section focuses on why those controls exist and how they align with:

  • ISO/IEC 27001

  • NIS2

  • Cyber Resilience Act (CRA)

  • GDPR

  • Customer security requirements

Together, they form a complete chain:

Requirement → Control → Implementation → Evidence

Solution areas covered

The following solution domains are documented in detail:

  • Secure Software Lifecycle (SSLM)

  • Vulnerability Lifecycle & Supply-Chain Governance

  • Cloud Security Foundations

  • SOC & SIEM Modernisation

  • CNAPP and Kubernetes Security Architecture

What this section does not replace

These documents do not replace:

  • Formal policies or ISMS documentation

  • Legal interpretations of regulations

  • Vendor security documentation

  • Auditor judgment

They exist to ensure that what is documented can be implemented and proven.

Next steps

Start with the solution most relevant to your current challenge:

  • If delivery speed and compliance are in tension → Secure Software Lifecycle

  • If audits or tenders are blocked → Vulnerability Lifecycle or Evidence Library

  • If ownership is unclear in the cloud → Cloud Security Foundations

  • If detection and response are immature → SOC & SIEM Modernisation

  • If containers and Kubernetes are in scope → CNAPP & Kubernetes Architecture
