Ops Quantum Impact
Understand how the quantum threat impacts IT operations — certificates, VPN/SSH, monitoring, and deployment pipelines.
Why this matters: Certificate scaling and fleet upgrades are operational problems, not cryptographic ones — the algorithm choice is a one-time decision, but the rollout across thousands of endpoints is where PQC migrations actually succeed or fail.
Start here: Build the operational action plan in How to Act: from infrastructure inventory to a pilot migration, with certificate, VPN/SSH and pipeline work in order.
For your role
- IT Ops / DevOps
- Score your operational exposure across nine criteria, then build the action plan from infrastructure inventory onward: certificate scaling, fleet upgrades, VPN and SSH key exchange and monitoring recalibration are rollout problems, and the plan treats them that way.
For the IT Ops / DevOps
“You deploy, monitor, and operate the cryptographic infrastructure that protects the organization. PQC migration starts with your toolchain.”
Why This Matters for You
Certificate rotation, VPN tunnel configuration, SSH key management, and TLS termination are all in your domain — and all will change with PQC. Larger certificates, different key exchange protocols, and new monitoring thresholds mean your operational playbooks need updating before the migration begins. If you manage the infrastructure, you are on the front line of the quantum transition.
Key Threat Impacts
Certificate Rotation at Scale
PQC certificates are roughly 4-7x larger than typical ECDSA certificates (SLH-DSA-based certificates can run considerably larger still). Automated certificate management (ACME, cert-manager) needs testing with new sizes.
2025-2028
VPN & SSH Key Exchange Upgrades
IPsec IKEv2 and SSH key exchange protocols must transition to PQC across entire device fleets.
2025-2030
Performance Monitoring Thresholds
PQC operations have different performance profiles. Existing monitoring baselines, alerts, and SLAs need recalibration.
2025-2028
CI/CD Pipeline Updates
Build, sign, and deploy pipelines need PQC-aware signing verification and certificate validation.

Quick Wins to Start Today
List all your TLS certificates
Run a certificate discovery scan. Most organizations don’t know their full cert inventory.
Check your OpenSSH version
OpenSSH 9.x supports hybrid PQC key exchange. Run `ssh -V` on your servers.
Check your VPN vendor’s PQC roadmap
Cisco, Palo Alto, and Fortinet have published PQC support timelines.
