IRAP requirement: Commonwealth and state government procurement increasingly mandates IRAP assessment of all cloud services handling government information. Non-IRAP-assessed email providers cannot be used for OFFICIAL: Sensitive information regardless of brand recognition.

Regulatory Landscape

Government email compliance in Australia

Every compliance obligation that applies to government email — and how ShieldBox satisfies each one.

ASD / IRAP
IRAP Assessment

ASD-administered IRAP assessment is the primary mechanism for assuring government ICT security. ShieldBox holds a current IRAP assessment covering OFFICIAL and OFFICIAL: Sensitive classification levels for all email infrastructure.

AGD / PSPF
Protective Security Policy Framework

The PSPF mandates how Commonwealth entities protect official and sensitive information including email. Australian data residency is a PSPF requirement for all OFFICIAL: Sensitive and above communications.

ASD / ISM
Information Security Manual (ISM)

The ASD ISM specifies technical controls for Australian Government email — DMARC enforcement, AES-256 encryption, TLS 1.2+, MFA for all access, 7-year audit log retention, and IRAP-assessed infrastructure.

ASD Essential Eight
ASD Essential Eight ML2

Essential Eight Maturity Level 2 is the standard baseline for most government agencies and contractors. ShieldBox is verified at ML2 with a pathway to ML3 for agencies requiring the highest assurance level.
