Secure Cloud Gateway (Modern SIG)

Modern SIG. Mission-Ready. Built for Government.

Australia’s threat landscape is evolving—and so is the way government agencies and critical infrastructure organisations protect their digital boundaries. Digital61’s Secure Cloud Gateway (SCG) is a next-generation alternative to legacy Secure Internet Gateways (SIGs), designed to meet the evolving requirements of the Protective Security Policy Framework (PSPF) and the Information Security Manual (ISM).

Why a Secure Cloud Gateway?

Following changes to the Australian Government’s gateway policy, agencies are no longer required to consume ASD-certified gateways. Instead, each Non-Corporate Commonwealth Entity (NCE) is empowered to make risk-based decisions and engage IRAP-assessed solutions that meet their specific operational, security, and compliance needs.

Digital61’s Secure Cloud Gateway aligns with this new model by delivering:

  • Cloud-native architecture – Secure by design, scalable by need

  • IRAP-assessed components – Aligned with PSPF

  • Flexible deployment – Multi-tenancy, single-tenant, or service-specific models

  • Integrated monitoring – SOC-ready integration with SIEM, SOAR, and threat intelligence
