Still Cyber Podcast Ep 04 – Quantum Challenges & Certificate Overload: Certs, AI, and the Road to Post-Quantum Security

January 28, 2026

In this week’s Still Cyber, After All These Years, Alan Shimel sits down with Brian Trzupek, SVP of Product at DigiCert, for a wide-ranging conversation about the evolving complexities of digital trust — even as Mitchell contends with the aftermath of the “snow-pocalypse.” Alan and Brian unpack how AI is dramatically increasing certificate inventories, with many organizations now managing tens of thousands of unique certificates, and why that matters for risk and automation. They explore the industry’s transition to a 47-day certificate expiration cycle (seriously — who picked 47 days anyway?) and the implications for operations, outages, and governance.

From modern certificate management, the discussion moves to the future of cryptography: how prepared are we for post-quantum cryptography when Q-Day arrives? Alan and Brian also highlight an exciting initiative in the quantum security space — the Quantum Security 25, a joint venture between Techstrong Group and DigiCert to spotlight the top 25 most influential leaders shaping quantum-secure futures. Nominations are still open, so listeners who want to nominate quantum security leaders can do so via the official form here: Nominate for Quantum Security 25 (quantumsecurity25.com nomination form) (Quantum Security 25)

Tune in for candid insights on securing machine identities, navigating cryptographic change, and the human side of building trust in an increasingly automated and quantum-forward world.
