Cyber Insights 2026: Information Sharing

Cyber Insights 2026: Information Sharing notes that information sharing is necessary and widespread for cybersecurity, but never perfectly effective. The piece highlights rapid, public-private collaboration that helped detect and respond to the Salt Typhoon intrusion in late 2024, with lessons disseminated across sectors, aided by CISA’s framework.

It details two CISAs—Cybersecurity Information Sharing Act of 2015 and the Cybersecurity and Infrastructure Security Agency Act of 2018—with the former having passed its sunset date on 30 September 2025 and being temporarily reauthorized until 30 January 2026; without renewal, the information‑sharing framework could be weakened, threatening timely IoC reporting.

The article also discusses the strain on CISA, including funding cuts of almost $500 million, and notes that gaps in timeliness and relevance persist as threat intelligence grows in volume and complexity. It mentions ISACs, InfraGard, IC3, and private CISO communities as key channels, while warning that high‑volume feeds risk low fidelity unless platforms enable anonymised sharing and proper governance.

Finally, it anticipates that information sharing will continue to rise in 2026 and beyond, yet faces challenges around speed, context, and balance between openness and risk. according to Cybersecurity Information Sharing Act of 2015
