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.
Key Points
- 1Report finds 66% cite legacy systems as main barrier to Zero Trust adoption
- 2Highlights rapid threat growth: ransomware up 60% year-on-year, AI-powered phishing surged 76%
- 3Advise layering AI over legacy systems to enable adaptive auth, monitoring, and microsegmentation
Scoring Rationale
Actionable, industry-focused guidance supported by DXC data and policy alignment, but vendor bias limits independent verification and broader generalizability.
