Operational Resilience

Regulatory compliance and operational resilience

ASIC and APRA require firms to maintain critical operations through severe disruptions. Legacy systems are the single biggest risk to operational resilience.

Talk to us about operational resilience

Operational resilience alignment

Architecture mapped to ASIC and APRA requirements for maintaining critical operations.

Business continuity during migration

Parallel running ensures zero disruption until the target is validated.

Disaster recovery built in

Multi-AZ deployment and automated failover designed into the target state.

Vendor concentration risk management

Multi-cloud strategies and portable infrastructure-as-code reduce single-vendor dependency.
