How global enterprises are re-architecting software-defined WANs with modular post-quantum tunnels and automated algorithm lifecycle management.
Traditional corporate WANs relied on expensive, private MPLS circuits. Modern enterprises utilize Software-Defined WAN (SD-WAN) across public commercial internet links, relying on IPsec and WireGuard tunnels for security. Upgrading these tunnels to resist quantum harvesting is the top infrastructure priority for multinational corporations.
We explain how SD-WAN edge appliances establish post-quantum tunnels automatically upon power-up, utilizing Zero-Touch Provisioning (ZTP) and automated certificate enrollment to distribute ML-KEM keys across thousands of branch offices without manual configuration.
