As the US government shutdown begins, critical questions emerge about how funding instability threatens the nation’s cyber defense. In this urgent episode of The Cyber Resilience Brief, Tova and Adrian unpack the “dual threat” facing CISA: the looming expiration of the Cybersecurity Information Sharing Act of 2015, and deep budget cuts that could decimate its operational capacity. We explore how these pressures risk crippling CISA’s ability to issue timely, actionable threat alerts—and what that means for CISOs trying to protect their networks today. Beyond CISA, we highlight the domestic agencies and international partners stepping up to fill the gap, from the FBI to the Five Eyes alliance. This episode is a must-listen for security leaders navigating a moment where US cyber resilience hangs in the balance.Disclaimer: SafeBreach, The Cyber Resilience Brief, and hosts Tova and Adrian do not hold any particular views regarding the US government shutdown.
