Cloud
Security.
Secure-by-design cloud architecture - landing zones, identity, segmentation, workload protection and assurance for regulated Azure and AWS environments.
Enterprise architects, cloud platform teams and security leaders migrating to, or maturing on, Azure and AWS under Australian regulatory expectations.
HEXOSYS designs and reviews cloud security architecture that holds up to scrutiny - from secure landing zones and identity-centric control planes to network segmentation, workload protection, logging and independent assurance mapped to the frameworks you answer to.
Key capabilities
Secure landing zones and cloud foundation architecture
Identity-centric access and control-plane security
Network segmentation and Zero Trust patterns
Workload, container and platform protection
Logging, monitoring and detection architecture
Cloud compliance mapping to Essential Eight, ISM, CPS 234 and VPDSF
Typical outcomes
A cloud foundation that is secure by design, not retrofitted
Demonstrable control coverage in Azure and AWS
Reduced attack surface through sound segmentation and identity
Assurance evidence aligned to Australian obligations
Frameworks & standards we work to
We architect and assure to the frameworks that govern Australian and New Zealand organisations.
Australian government & national: ASD Information Security Manual (ISM) — our primary reference for government and Defence-adjacent work — ACSC Essential Eight, PSPF, and the SOCI Act critical-infrastructure obligations including CIRMP alignment.
Financial services (APRA): CPS 234 Information Security, CPS 230 Operational Risk Management and operational-resilience expectations, with security architecture supporting CPS 220 risk-management alignment.
International & industry: ISO/IEC 27001, NIST CSF, CIS Critical Security Controls and CIS Benchmarks for platform hardening.
New Zealand: NZISM and CERT NZ Critical Controls for engagements across our NZ practice.
Operational technology: IEC 62443 (zones-and-conduits security architecture), ACSC operational technology security principles, and NIST SP 800-82 guidance alignment; AESCSF for energy-sector engagements.
Platforms & patterns
Security architecture and assurance across Microsoft Azure, AWS and SaaS/PaaS estates: secure workload accreditation support, Zero Trust architecture patterns, secure configuration and cloud risk reviews aligned to the ISM, Essential Eight, ISO/IEC 27001 and NIST CSF.
Private cloud & SDDC security
Design and assurance for VMware Software-Defined Data Centre estates, including current-generation VMware Cloud Foundation: vDefend and Security Services Platform architecture, NSX Distributed Firewall macro- and micro-segmentation with dynamic security groups and policy-based tagging, Distributed Firewall policy hierarchy and lifecycle design, Advanced Threat Prevention integration (IDS/IPS, NDR, malware analysis), Illumio micro-segmentation, vSphere/ESXi hardening to CIS Benchmarks, and NSX Tier-0/Tier-1 routing with overlay networking for controlled east-west traffic.
Identity & access
Entra ID architecture (Conditional Access, MFA, RBAC, SSO), Okta and federation patterns, privileged access management, API security controls, and PKI/certificate lifecycle design including automated certificate management.
Detection & monitoring
SIEM strategy and uplift across Microsoft Sentinel and Splunk, detection use-case development aligned to threat scenarios, Microsoft Defender adoption, and network detection and response integration.
HEXOSYS has delivered cloud security outcomes across Australian federal government, Defence, APRA-regulated financial services, aviation and critical infrastructure, state government and education, and local government.
