CISA 2025 Year in Review focuses on driving security and resilience across critical infrastructure

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has released its 2025 Year in Review, outlining key actions taken to strengthen the nation’s cyber and physical defenses. The report highlights progress across critical infrastructure security, operational resilience, and interagency collaboration, framing the agency’s work within shifting threat conditions and evolving policy priorities. CISA notes that its objectives adapt each year to reflect changes in the risk landscape and align with administration-directed mission goals.

Titled CISA’s 2025 Year in Review: Driving Security and Resilience Across Critical Infrastructure, the report states that the agency modernized operations, accelerated threat response efforts, and worked closely with government and industry partners to safeguard critical infrastructure while maintaining responsible stewardship of taxpayer funds.

Among the highlights, CISA strengthened collective defense by publishing more than 1,600 cybersecurity products and triaging more than 30,000 incidents through its 24/7 Operations Center to help keep critical systems secure. The agency reported blocking 2.62 billion malicious connections across federal civilian networks and 371 million across critical infrastructure environments. It also led 148 cyber and physical security exercises involving more than 10,000 participants to help partners refine emergency response plans and strengthen resilience at both local and national levels.
