Strengthening America’s critical infrastructure requires collaboration across industries, sectors and technologies.

The Alliance for Critical Infrastructure (ACI) brings together leading companies across communications, energy, financial services, information technology, transportation, and water systems to strengthen the physical and cyber resilience of America’s critical infrastructure.

ACI provides a cross-sector forum to identify shared vulnerabilities, better understand critical dependencies, strengthen collective defenses, and prepare for emerging risks.

 The alliance combines practical experience and technical expertise from companies that operate the systems Americans rely on every day.

ACI is industry-led and works closely with government to support national security, advance sound public policy, and strengthen preparedness and recovery.

 Its work is intended to benefit the broader critical infrastructure community, including operators of all sizes, through shared best practices and practical insights.
