Post quantum migration is the thing nobody in SMB is talking about… and timelines make that a problem

NIST finalized three post-quantum cryptography standards in August 2024… FIPS 203, 204, and 205… replacing RSA and ECC for key exchange and digital signatures Most enterprise security teams are at least tracking this. most small SaaS companies are not. and SMB migration timelines run 3–4 years for discovery and planning alone, extending to 8–10 years for full completion. critical infrastructure regulation is expected between 2026–2028, financial services between 2028–2032 Specific risk that changes the urgency for companies handling sensitive long-lived data is “harvest now, decrypt later”… adversaries storing encrypted traffic today for decryption once quantum capability exists. data collected in 2026 that gets decrypted in 2031 is still a HIPAA violation, still damaging, still your problem Practical starting point for smaller teams… do a cryptographic inventory first. Find every place your stack uses asymmetric encryption… and a lot of it is in libraries and cloud provider defaults you didn’t explicitly choose. JWT signing algorithm (RS256/ES256), TLS cert type, KMS configuration, S3 encryption setting Then check vendor roadmaps. AWS, GCP and Azure all have PQC roadmaps published. OpenSSL 3.x supports hybrid PQC in experimental mode. Most of the migration path at the TLS layer can be handled via config with no code changes Full writeup with a 5-step checklist here (no paywall)… www.snippipedia.com/logs/post-quantum-cryptography-small-business submitted by /u/snippipedia [link] [comments]Technical Information Security Content & DiscussionRead More
