Preparing for the post-quantum era: Discover and prioritize now
Curated from HashiCorp Blog
Most organizations treat post-quantum cryptography as a distant theoretical problem, yet the timeline for quantum threats is compressing faster than anticipated. The immediate danger is not the quantum computer itself, but the harvesting of encrypted data today for decryption tomorrow. If you assume migration is purely a cryptographic update, you are overlooking the massive operational overhead of inventorying every algorithm, certificate, and handshake across your infrastructure. This article shifts the focus from immediate implementation to strategic discovery. It emphasizes that you cannot protect what you cannot see. Before selecting a specific NIST-standardized algorithm, you must map your current cryptographic footprint and identify legacy systems that cannot be easily upgraded. The real work lies in prioritizing assets based on data sensitivity and exposure, rather than reacting to vendor pressure. Start with an inventory audit to understand your true attack surface.
As organizations prepare for the post-quantum era, it may seem natural to immediately dive into quantum-safe cryptography migration efforts.
