Harvest Now, Decrypt Later: Most Organizations Still Aren't Ready for the Quantum Cryptography Shift
NIST published its first three post-quantum standards in 2024. A year later, only 5% of security teams have a defined strategy. The clock is running whether they know it or not.
Starmer's Device-Scan Mandate Puts Enterprise Encryption in the Crosshairs
The UK Prime Minister gave tech firms three months to build image-filtering controls into every device. Security leaders say the architecture required would gut encryption protections, create fresh exfiltration paths, and hand future governments a surveillance tool the current one insists it doesn't want.
