CISA’s Expiration Creates a Critical Gap in US Cyber Collaboration

Essential Insights

1. The expiration of the Cybersecurity Information Sharing Act (CISA) in 2025 has led to a significant decline in threat intelligence sharing, increasing vulnerabilities across critical sectors like healthcare, energy, and finance.
2. Without CISA’s liability protections and privacy safeguards, organizations are hesitant to report cyber incidents, causing data silos and reduced federal and industry visibility into threats.
3. The law’s lapse has disrupted near-real-time detection and response capabilities, resulting in attacks becoming more frequent and sophisticated, with delayed alert dissemination and slower response times.
4. Reauthorization efforts, such as the “Protecting America from Cyber Threats Act,” aim to modernize and expand the framework—integrating AI, promoting international cooperation, and establishing trust to restore resilient cybersecurity defenses.

The Core Issue

The expiration of the Cybersecurity Information Sharing Act (CISA) in September 2025 has critically undermined the United States’ cyber-defense infrastructure, severing a decade-long legal framework that facilitated secure and rapid exchange of threat intelligence between government agencies and private industry. Without this law, organizations have scaled back their voluntary sharing of vital threat data—such as malware signatures and attack tactics—leading to significant delays in alert dissemination and a noticeable rise in cyberattacks across sectors like healthcare, energy, and finance. This has created a troubling gap in national security, as the absence of liability protections discourages entities from reporting cyber incidents, fostering data silos and reducing overall threat visibility just as malicious actors exploit automation, AI, and geopolitical tensions to target critical infrastructure.

Amid mounting risks, U.S. legislators, including Senators Gary Peters and Mike Rounds, are advocating for the swift reauthorization of a modernized CISA that leverages AI-driven analytics, real-time data sharing, and expanded international cooperation. The primary goal is to restore and enhance trust, transparency, and collaboration—principles that underpinned the law’s original success—so that both public and private partners can respond swiftly to ever-evolving cyber threats. The report, authored by Michael Centrella, emphasizes that allowing the current legal void to persist not only hampers immediate defense capabilities but exposes the nation to escalating cyber vulnerabilities in a rapidly interconnected digital landscape.

Security Implications

The expiration of CISA’s authorization could create a perilous gap in cyber collaboration within the U.S., and any business—regardless of size or industry—risks facing this threat firsthand; without this crucial federal agency’s leadership, information sharing, coordinated incident response, and strategic cybersecurity initiatives may falter, leaving organizations more vulnerable to damaging cyberattacks, data breaches, and systemic vulnerabilities that can inflict financial losses, erode customer trust, and hinder operational resilience — ultimately endangering their competitive edge and long-term stability in an increasingly interconnected digital landscape.

Fix & Mitigation

Ensuring prompt response and remediation in cybersecurity is crucial to closing vulnerabilities swiftly, especially when gaps like CISA’s expiration create significant risks. Delays in addressing security issues can be exploited by malicious actors, compromising critical infrastructure and sensitive data, and eroding public trust.

Rapid Response

• Establish clear incident response protocols to quickly identify and contain threats.
• Implement real-time monitoring tools for immediate detection of anomalies.

Continuity Planning

• Develop and regularly update business continuity and disaster recovery plans to sustain operations during cyber incidents.
• Conduct frequent drills and simulations to ensure preparedness for various scenarios.

Vulnerability Management

• Maintain a prioritized patch management strategy to address known vulnerabilities without delay.
• Conduct continuous vulnerability assessments to identify new weaknesses.

Stakeholder Engagement

• Foster collaboration between government agencies and private sector entities to share threat intelligence swiftly.
• Define clear communication channels to coordinate remediation efforts effectively.

Policy and Frameworks

• Develop policies emphasizing rapid attribution and response for cyber threats.
• Align organizational procedures with NIST Cybersecurity Framework standards to ensure structured and effective mitigation.

Legal and Regulatory Compliance

• Ensure adherence to cybersecurity laws and regulations that mandate timely action and reporting.
• Advocate for policies that support rapid response efforts and resource allocation.
