Security Architecture Review
Architecture flaws are the hardest vulnerabilities to fix and the most expensive to discover after deployment. A security architecture review catches design-level weaknesses — trust model gaps, segmentation failures, single points of failure — before they become real attack paths.
What Is a Security Architecture Review?
A security architecture review evaluates the design of your network, cloud, and hybrid infrastructure against security best practices, threat models, and your own risk requirements. It examines trust boundaries, data flows, access controls, and defensive layers to find weaknesses that vulnerability scanners and penetration tests miss.
Architecture reviews are most valuable before deployment (design review) or during major infrastructure changes. Fixing a segmentation gap during design costs a fraction of what it costs to rearchitect after an attacker exploits it.
What’s Covered
Architecture review components.
Network Architecture
Topology review covering segmentation, firewall placement, DMZ design, inter-zone routing, and trust boundary enforcement. Identifies lateral movement paths and isolation failures.
Cloud Architecture
AWS, Azure, or GCP architecture review. Landing zone design, IAM hierarchy, network configuration, and cloud-native security control evaluation.
Zero Trust Assessment
Evaluation of your Zero Trust posture. Identity verification, least privilege access, micro-segmentation, and continuous validation. Measured against NIST SP 800-207 principles.
Hybrid Architecture
Connectivity between on-premises and cloud environments. VPN/ExpressRoute design, identity federation, DNS architecture, and data flow across environments.
Application Architecture
Service-to-service communication, API security architecture, authentication flows, and data flow diagrams. Catches design flaws before code is written.
New Deployment Reviews
Design reviews for planned infrastructure changes, new environments, or major architecture upgrades. Pre-deployment validation catches expensive mistakes.
Our Approach
Structured review, practical recommendations.
Architecture Documentation
We collect architecture diagrams, network configurations, cloud resource inventories, and access policies. If documentation is missing or outdated, we build it through discovery.
Threat-Led Analysis
Each architecture component analysed against relevant threat scenarios. Trust boundaries mapped, attack paths identified, and defensive layers evaluated for coverage gaps.
Gap Identification
Findings documented with severity, impact, and remediation guidance. Architecture-level recommendations (not just patch this server) with implementation complexity estimates.
Remediation Roadmap
Prioritised remediation plan with phased milestones. Critical architectural changes separated from incremental improvements. Cost-benefit analysis for significant changes.
Why Bravix Architecture Review?
Offensive Validation
Our architecture reviews come from consultants who exploit networks for a living. They identify attack paths that pure architects and auditors miss because they have walked those paths during red team engagements.
Zero Trust Focus
We do not validate perimeter models and call it done. Zero Trust assessment is core to every review — trust boundaries, identity verification, and lateral movement prevention.
Multi-Platform
On-premises, cloud, hybrid, SaaS. We review the full picture, not just the parts that fit a single platform’s security model.
Actionable Output
Clear findings with architecture-level remediation guidance. Not a list of CVEs — structural recommendations that improve your security posture for the long term.
Review Your Security Architecture
Find architectural weaknesses before attackers do. Reviews informed by offensive security experience and validated against real-world attack patterns.
