What security teams should do to prepare for the quantum computing future - CyberScoop

Quantum computing poses an imminent threat to current encryption standards, warns QuSecure CEO Rebecca Krauthamer, urging immediate adoption of post-quantum cryptography to prevent future data breaches. Governments and industries are accelerating responses to "Q-Day"—the point when quantum computers break classical encryption—with new policies and frameworks to mitigate risks before operational quantum systems emerge. Krauthamer emphasizes practical metrics for organizations, including cryptographic agility and hybrid encryption, to assess readiness and transition smoothly before quantum attacks become viable. Cybersecurity teams must prioritize long-term data protection, as harvested encrypted data today could be decrypted retroactively once quantum computers achieve sufficient power. The urgency extends to policymakers, technologists, and enterprises, who must collaborate on standards, funding, and workforce training to secure infrastructure against quantum-driven cyber threats.
