Major US Cybersecurity Law Expires Amid Government Shutdown
A major shift has occurred in the US cyber defense landscape as the Cybersecurity Information Sharing Act (CISA) expired on October 1, 2025. This foundational law facilitated essential sharing of cyber threat intelligence between the private sector and federal agencies, offering legal protections that eased participation from businesses. Its expiration, triggered by a government shutdown, threatens to severely reduce information sharing at a time of heightened cyber risk.
Background of CISA and Its Role in US Cybersecurity
The Cybersecurity Information Sharing Act was enacted to bridge the gap between organizational silos in cyber defense. It established the Department of Homeland Security as the central node for distributing threat data and enabled private entities to share details about cyber attacks, indicators of compromise, and best practices while shielding them from legal liabilities such as lawsuits and antitrust concerns. This collaborative approach helped mitigate the spread and severity of cyber threats nationwide.
Legal Protections and Potential Consequences of Lapse
The critical feature of CISA was its legal safe harbor: businesses contributing to the federal threat information pool were protected if they acted in good faith, encouraging robust participation from across industries. Attorneys from major law firms have warned that removal of this shield could chill cooperation, with projections that information sharing may drop by as much as 80%. Entities may be far less willing to share actionable intelligence, fearing legal or competitive repercussions.
Immediate and Long-Term Impact on Cyber Threat Response
The Department of Homeland Security has pledged to preserve the technical platform supporting information sharing in the near term, even as the statutory framework lapses. However, absence of explicit legal protections increases risk for all parties involved, potentially degrading the timeliness and accuracy of threat intelligence dissemination. The mistake comes at a vulnerable period, as the frequency and severity of cyber attacks continue to rise.
Outlook for US Cyber Defense Coordination
Resumption or renewal of CISA remains uncertain, dependent on government funding and legislative priorities. Meanwhile, private entities are left assessing risk exposure and may be forced to rely more heavily on private-sector-only threat information exchanges, which historically have struggled with reach and comprehensiveness. Analysts warn that this development could lead to fragmented, less coordinated defense efforts, raising the stakes for US critical infrastructure and private sector assets under mounting digital threats.
Record-Breaking DDoS Attack Reveals Rising Threat to Global Internet Infrastructure
In late September 2025, a new record was set for the largest distributed denial of service (DDoS) attack ever recorded, peaking at 22.2 terabits per second and 10.6 billion packets per second.
