ARCHITECTURE-DRIVEN SECURITY ASSURANCE
Security Architecture Review
Evaluating enterprise security architecture across trust boundaries, identity, network, cloud, and resilience domains to confirm controls collectively prevent lateral movement, privilege escalation, and data exposure under realistic threat conditions.
NetSentries Security Architecture Review (SAR) provides evidence-based assurance across eight integrated assessment domains encompassing over 120 control points. Rather than evaluating tools or configurations in isolation, SAR validates whether your security architecture collectively enforces trust boundaries, contains blast radius, and detects abuse under realistic adversary conditions — delivering CISOs and risk leaders clear visibility into architectural gaps and remediation priorities.
01
TRUST BOUNDARY DESIGN & DEFENSE-IN-DEPTH
Architecture & Trust Boundaries Review
Validating that foundational security architecture enforces trust boundaries across all tiers and environments under realistic abuse scenarios. We confirm that defense-in-depth is technically implemented rather than existing only in documentation — identifying where architectural bypasses circumvent intended security layers.
Trust boundary enforcement validation — confirming zone transitions require explicit authentication and authorization
Data flow mapping & classification — tracing sensitive data across trust boundaries and encryption gaps
Tier separation & defense-in-depth — verifying web, application, database, and management tier isolation
Internet-facing attack surface analysis — enumerating external entry points and perimeter control effectiveness

SEGMENTATION, LATERAL MOVEMENT & ZERO TRUST
Network Architecture & Segmentation Review
Verifying that network segmentation controls genuinely isolate critical assets, constrain lateral movement, and limit blast radius under realistic adversary conditions. We map attack paths from common compromise points to high-value targets and validate that firewall policies enforce least-privilege communication.
Lateral movement path analysis — mapping adversary routes from endpoints to domain controllers and databases
Firewall policy & rule hygiene — identifying over-permissive rules and 40–60% consolidation opportunities
Management network isolation — validating privileged access paths and bastion host hardening

Security Technology Stack Review
Evaluating the breadth, maturity, and integration effectiveness of security tools deployed across endpoints, networks, cloud, and applications. Typical enterprises deploy 45–75 security tools with 30–40% overlap — we identify rationalization opportunities while ensuring collective detection and response coverage.
EDR & XDR architecture assessment — endpoint detection coverage, cloud workload extension, and response capability
NDR & network visibility review — traffic analysis, encrypted flow inspection, and lateral movement detection
Cloud security platform assessment — CSPM, CWPP, and cloud-native detection and response integration

Cloud & Container Architecture Review
Evaluating cloud infrastructure security design including landing zones, identity architecture, and container orchestration to confirm cloud-native workloads enforce equivalent access controls and monitoring. Industry research indicates 50–70% of cloud breaches result from misconfiguration rather than software vulnerabilities.
Cloud landing zone & account architecture — account isolation, cross-tenant prevention, and multi-cloud governance
