The countdown to “Q-Day” just got terrifyingly real, as recent breakthroughs suggest adversaries could shatter traditional encryption using a fraction of the quantum computing power previously thought necessary. Rebecca Krauthamer, CEO of QuSecure, warns that while the government has drawn a hard line in the sand for 2027 , paralyzed enterprises are wasting precious time trying to invent a perfect migration plan for their legacy infrastructure. To survive the inevitable era of “harvest now, decrypt later” , organizations must stop waiting for an official announcement that the cryptography sky has fallen and immediately deploy post-quantum, crypto-agile overlays that can adapt to new threats before the ink on the latest algorithms even dries.
