I’ve seen security paradigms shift, but few are as fundamental as the one coming from post-quantum cryptography (PQC). Our current security, built on algorithms like RSA, is strong today. But a powerful quantum computer will one day render them obsolete, creating an existential threat to all encrypted data.
A sophisticated attacker can “harvest now, decrypt later,” stealing your data today and storing it until quantum computers can break the encryption. Preparing for this isn’t a future problem—it’s a present-day imperative.
The first step is visibility, and that’s where a tool like pqcscan comes in. It’s a simple, pragmatic scanner that identifies which of your services support post-quantum cryptography. It audits protocols like TLS/SSL and SSH, providing a clear inventory of your PQC readiness.
For the next generation of IT leaders, understanding PQC is a mark of strategic foresight. It shows you’re not just reacting to today’s threats but proactively building a roadmap to secure your organization against a future that will fundamentally change how we protect data. Embracing this now positions you as a forward-thinking professional.
