Key Areas We Assess

We assess how your application's design and controls protect its users, data, and functions.

Identity & Access Design

Identity & Access Design

Authentication, authorization model, session design, and service-to-service trust.

Data Protection

Data Protection

Data classification, encryption, key management, and data flow controls.

Integrations & APIs

Integrations & APIs

API gateways, third-party services, webhooks, and partner connections.

Trust Boundaries & Isolation

Trust Boundaries & Isolation

Tenant isolation, component separation, and privilege boundaries.

Deployment & Hosting

Deployment & Hosting

Cloud, container, and hosting design supporting the application.

Logging & Resilience

Logging & Resilience

Security logging, monitoring hooks, error handling, and failure modes.

Our Architecture Review Methodology

A design and control assessment grounded in documentation, workshops, and evidence.

Scope & Objectives
Scope & Objectives

Agree the application, components, review depth, and outcomes.

Documentation Review
Documentation Review

Review architecture diagrams, designs, data flows, and security standards.

Architect Workshops
Architect Workshops

Validate design intent and decisions with architects and engineers.

Control Assessment
Control Assessment

Assess identity, data protection, integration, and logging controls in the design.

Boundary Analysis
Boundary Analysis

Assess trust boundaries, isolation, and service-to-service trust.

Evidence Validation
Evidence Validation

Confirm key controls against configurations or implementation samples.

Reporting & Debriefing
Reporting & Debriefing

Receive design findings, risk ratings, and target-state recommendations.

Roadmap & Follow-Up
Roadmap & Follow-Up

Agree a phased improvement roadmap and review progress.

Deliverables

Every engagement delivers design findings your architects can act on.

Board-ready view of architectural risk and priorities.

Design and control gaps, with evidence and risk ratings.

Design changes for identity, data protection, integrations and deployment.

Phased plan to move from current to target architecture.
Deliverables

Strengthen Your Security Coverage

Extend architecture review into application testing, code review, and cloud security.

Web Application Security Testing

Web Application Security Testing

Test the running web application to confirm exploitable weaknesses.

API Security Testing

API Security Testing

Test REST, GraphQL, and SOAP APIs for access, data exposure, and logic flaws.

Secure Code Review

Secure Code Review

Review source code where the design review points to high-risk logic.

Cloud Security Audits

Cloud Security Audits

Review the cloud accounts and services that host your application.

Benefits of Application Security Architecture Review

Fix structural weaknesses that testing alone cannot resolve.

Fewer Design Flaws

Address weaknesses before they repeat across features.

Consistent Controls

Apply identity, data, and logging controls the same way across components.

Clear Roadmap

Plan and budget security improvements in phases.

Improved Compliance Readiness

Support secure design evidence for ISO 27001, SOC 2, and PCI DSS.

Benefits of Web Application Security Testing

Frequently Asked Questions

An architecture review assesses design and controls from documentation, workshops, and evidence. Penetration testing attacks the running application to confirm exploitable weaknesses.

Threat modelling identifies threats against a design. An architecture review assesses whether the design and its controls meet security requirements. They often complement each other.

Architecture diagrams, data flows, security standards, and time with architects and engineers for workshops.

No active testing is performed by default. Penetration testing or code review can be added to validate findings.

Before building or re-platforming, before major integrations or cloud moves, and when customers or auditors ask for design assurance.
