Secure by Design. Compliant by Default.

Effective cloud security requires more than technology—it demands deep expertise, sound governance, and a clear understanding of both the AWS platform and the regulatory environments in which organisations operate.

At Nephology, our security practice is built on real-world experience gained from inside AWS itself. Our founder served as AWS Security Solutions Architect for Australia and New Zealand and contributed to the AWS Global Compliance Team, providing a unique perspective on how AWS security capabilities are designed, implemented, and applied within government, enterprise, and regulated industries.

This first-hand experience enables us to deliver practical, independent security advice that helps organisations confidently protect their cloud environments while meeting complex compliance obligations.

Security Built Into Your Architecture

The most effective security strategies are designed into cloud environments from the beginning—not added after deployment.

We help organisations develop secure AWS architectures that balance security, operational efficiency, scalability, and business agility.

Our security architecture services include:

• AWS security architecture reviews
• Secure landing zone design
• Identity and access management
• Network security architecture
• Data protection and encryption
• Governance and compliance
• Security posture assessments

Every recommendation is aligned to industry best practice, AWS Well-Architected principles, and your organisation’s risk profile.

Identity & Access Management

Identity is the foundation of cloud security.

We design AWS Identity and Access Management (IAM) solutions that implement the principle of least privilege while supporting operational flexibility and enterprise scale.

Our IAM services include:

• IAM policy design
• Role-based access control
• Federated identity integration
• AWS IAM Identity Center implementation
• Cross-account access management
• Multi-factor authentication

Strong identity management reduces risk while simplifying administration across complex AWS environments.

Network Security

A well-designed AWS network is your first line of defence.

We architect secure, scalable network environments using AWS-native services including:

• Amazon VPC
• Security Groups
• Network ACLs
• AWS Network Firewall
• AWS Transit Gateway (and/or VPC Peering)
• AWS Direct Connect
• AWS PrivateLink
• AWS WAF
• Secure hybrid connectivity

Our network designs minimise attack surfaces while ensuring secure communication between workloads, users, and external services.

Data Protection & Encryption

Protecting sensitive information requires more than simply enabling encryption. We design comprehensive data protection strategies covering:

• AWS Key Management Service (KMS)
• Encryption at rest
• Encryption in transit
• Key lifecycle management
• Data residency
• Data sovereignty
• Backup and recovery
• Secure storage architectures

Whether supporting government agencies or commercial organisations, we help ensure sensitive information remains protected throughout its lifecycle.

Threat Detection & Security Operations

Effective security requires continuous monitoring and rapid response.

We implement and integrate AWS-native security services to provide real-time visibility across your cloud environment, including:

• Amazon GuardDuty – Intelligent threat detection.
• AWS Security Hub – Centralised security posture management.
• Amazon Detective – Incident investigation and analysis.
• AWS CloudTrail – Comprehensive audit logging.

Together, these services provide comprehensive detection, investigation, and response capabilities that strengthen your overall security posture.

Compliance & Regulatory Frameworks

Meeting compliance obligations requires more than technical controls—it requires understanding how cloud architecture supports governance, auditability, and risk management.

Nephology provides advisory services across a broad range of Australian and international compliance frameworks.

Australian Government

We help organisations align AWS environments with:

• Information Security Manual (ISM)
• IRAP requirements
• ASD Essential Eight
• Australian Government cloud security guidance

Our experience supporting government environments allows us to translate compliance requirements into practical cloud architectures and operational controls.

Privacy & Data Protection

We assist organisations in meeting obligations under the Privacy Act 1988 and the Australian Privacy Principles (APPs) by implementing appropriate controls for:

• Data residency
• Access management
• Logging and auditing
• Information lifecycle management
• Cross-border data considerations

Security Posture Reviews

Many organisations know their cloud security can be improved but struggle to identify where to begin.

Our independent security assessments evaluate your AWS environment against:

• AWS Well-Architected Framework – Security Pillar
• AWS security best practices
• Regulatory obligations
• Industry standards
• Organisational risk appetite

Rather than delivering lengthy reports, we provide prioritised recommendations that focus on practical improvements with measurable security outcomes.

Our Security & Compliance Services

Typical engagements include:

• AWS security architecture assessments
• IAM reviews and remediation
• Secure network architecture design
• Encryption strategy development
• AWS security service implementation
• Security posture reviews
• Well-Architected Reviews
• Knowledge transfer and capability development

Every engagement concludes with a clear, prioritised roadmap that enables your organisation to strengthen security while building internal capability.
