Automating Post-Quantum IPsec on Cisco Routers – Part 12 of the IPsec Series

Cisco’s blog post “Automating Post‑Quantum IPsec on Cisco Routers – IPsec Series, Part 12” marks a significant shift from traditional command‑line configuration to full‑stack automation, using Ansible over NETCONF to provision IPsec tunnels that support post‑quantum cryptography.

The article explains that post‑quantum algorithms such as ML‑KEM for key exchange and ML‑DSA for digital signatures are now available on Cisco routers, providing resistance against future quantum attacks while maintaining compatibility with existing IPsec frameworks.

By defining a single posture file and an Ansible playbook, network engineers can deploy the entire tunnel configuration in minutes, with the automation engine verifying that the negotiated security parameters include the new ML‑KEM and ML‑DSA suites, dramatically reducing human error and operational overhead.

For Australian IT professionals and students, especially those in Darwin’s expanding networking sector, mastering these automation tools is becoming essential as enterprises modernise their security posture and prepare for quantum‑resistant communications.

Wepro Technology, an Australian IT training provider, now includes modules on Cisco DevNet automation, NETCONF, and post‑quantum IPsec in its curriculum, helping learners gain the skills needed to implement and manage these advanced security solutions.
