How to stay ahead of Post Quantum and a fast-changing PKI landscape

Ongoing changes in the PKI (Public Key Infrastructure) ecosystem and the challenges related to the transition toward Post-Quantum Cryptography (PQC) will be presented.

The main regulatory and market developments are analyzed: the progressive reduction in the validity of TLS and Code Signing certificates, the removal of Client Authentication, the introduction of PQC algorithms for S/MIME, and the upcoming phase-out of Domain Control Validation methods based on email and phone.

The presentation also highlights:

• the growing operational risks caused by short-lived certificates and the importance of automation (ACME/ARI);
• the advantages of using automation systems for certificate lifecycle management and crypto-agility;
• the roadmap toward post-quantum cryptography, emphasizing the urgency of planning the migration now.
