Security Architecture
Review

A strong security posture starts with sound architecture. We review your network, cloud, application, and identity architecture for design flaws, single points of failure, and defence-in-depth gaps that technical testing alone cannot find.

Review Areas

What We Review in Your Security Architecture

Comprehensive architecture review spanning network design, cloud infrastructure, application security, and identity architecture.

Network Architecture Review

Evaluation of network topology, segmentation strategy, zone design, and traffic flow for defence-in-depth compliance and single points of failure.

Firewall and DMZ Design

Review of firewall placement, rule architecture, DMZ design, and east-west traffic controls for gaps that allow lateral movement.

Data Centre Architecture

Assessment of physical and logical data centre security architecture including rack placement, network cabling, and redundant path design.

Encryption Architecture

Review of encryption design for data at rest, in transit, and in use, including key management architecture and certificate lifecycle.

Remote Access Architecture

Assessment of VPN, remote desktop, and zero-trust network access design for secure connectivity without exposing internal services.

Availability and Resilience Design

Review of high availability, disaster recovery architecture, backup design, and failover mechanisms to ensure business continuity.

Cloud Architecture Review

Assessment of AWS, Azure, and GCP architecture against Well-Architected Security Pillars, identifying misconfigurations at the design level.

Microservices Security Design

Review of API gateway architecture, service mesh security, inter-service authentication, and container orchestration security design.

Application Security Architecture

Evaluation of application-layer security design including authentication flows, session management, authorisation models, and data validation patterns.

Data Architecture Security

Review of data classification architecture, storage tiering, data lake security, and database access patterns for appropriate data protection.

CI/CD Pipeline Architecture

Assessment of build pipeline security design including artifact integrity, deployment controls, and environment separation architecture.

Integration and API Architecture

Review of API security gateway design, rate limiting architecture, OAuth implementation, and third-party integration security patterns.

Identity Architecture Review

Assessment of identity provider design, directory architecture, federation model, and privileged access management for security and scalability.

Access Control Architecture

Evaluation of RBAC, ABAC, and PBAC design patterns, permission models, and just-in-time access architecture for principle of least privilege.

Zero Trust Maturity Assessment

Assessment of your zero trust architecture maturity across the five pillars: identity, devices, networks, applications, and data.

Privileged Access Architecture

Review of PAM design including credential vaulting, session isolation, just-enough-access, and emergency access procedures.

Identity Governance Design

Assessment of joiner-mover-leaver processes, access certification architecture, and role lifecycle management for identity hygiene.

Federation and SSO Architecture

Review of SAML, OIDC, and OAuth federation design, SSO architecture, and multi-tenant identity models for secure cross-domain access.

Methodology

How We Run a Security Architecture Review

A structured six-phase programme from scope definition through to remediation roadmap.

Phase 01

Scope and Documentation Collection

Define review scope across network, cloud, application, and identity layers. Collect architecture diagrams, design documents, configuration standards, and security policies.

Phase 02

Architecture Mapping

Build comprehensive architecture diagrams from documentation and interviews, mapping all components, data flows, trust boundaries, and security controls across the environment.

Phase 03

Gap Analysis

Evaluate the mapped architecture against industry frameworks including NIST CSF 2.0, ISO 27001, CIS Controls, and Zero Trust maturity models to identify design weaknesses and control gaps.

Phase 04

Risk Assessment

Assess the business impact and likelihood of each architectural gap, identify single points of failure, cascade risks, and systemic weaknesses that affect the entire environment.

Phase 05

Remediation Roadmap

Develop a prioritised, phased remediation roadmap with specific architecture changes, control implementations, and timeline recommendations aligned to your risk appetite.

Phase 06

Validation and Ongoing Review

Validate remediation through targeted architecture review of changes, establish periodic architecture review cadence, and update diagrams and assessments as your environment evolves.

Who It's For

Who Needs a Security Architecture Review

Organisations Undergoing Transformation

Companies migrating to cloud, adopting zero trust, or modernising their infrastructure that need to ensure new architectures are secure by design.

Regulated Enterprises

Financial services, healthcare, and government organisations with regulatory obligations for secure architecture design under RBI, HIPAA, DORA, and PCI-DSS.

Post-Incident Organisations

Companies that have experienced a breach and need to identify and fix the architectural weaknesses that enabled the attack to prevent recurrence.

FAQ

Questions We Get Asked Often

A security architecture review evaluates the design and structure of your IT security controls across network, cloud, application, and identity layers. It identifies architectural weaknesses, single points of failure, and gaps in defence-in-depth that vulnerability scanning and penetration testing cannot detect.

A penetration test finds specific technical vulnerabilities in running systems. An architecture review examines the overall design and structure, identifying fundamental weaknesses like flat networks, missing segmentation, inadequate identity architecture, and single points of failure that create systemic risk across your environment.

We review network architecture, cloud architecture (AWS, Azure, GCP), application architecture and microservices design, identity and access management architecture, zero trust architecture maturity, and hybrid or multi-cloud designs.

We align reviews to NIST CSF, ISO 27001 Annex A, CIS Controls, Zero Trust maturity models, and cloud-specific frameworks like AWS Well-Architected Security Pillar and Microsoft Cloud Security Benchmark (MCSB).

You receive a comprehensive architecture review report with detailed findings, risk-rated gaps, architecture diagrams with annotated weaknesses, a prioritised remediation roadmap, and executive summary with strategic recommendations for your leadership team.
