Government Adopts AI-Enabled Zero Trust Architecture

Australian public sector agencies face escalating AI-enabled cyber threats and legacy-system constraints, and DXC recommends adopting an AI-enhanced Zero Trust model to integrate with existing infrastructure. DXC's 2025 Trust Report finds 66% of organisations cite legacy systems as the biggest barrier, while agencies spend up to 80% of IT budgets on maintenance; ransomware rose 60% and AI phishing surged 76%. The approach prioritises MFA, adaptive authentication, monitoring and microsegmentation.
