Facing Quantum Uncertainty with Fortinet

**Executive Summary:** Fortinet is embedding post-quantum cryptographic algorithms into FortiOS across versions (from IPsec PQ preshared keys in 7.2 to ML-KEM/ML-DSA and hybrid PQ crypto in 8.0), enabling organizations to adopt quantum-safe tunnels on existing hardware while accepting initial tunnel-setup performance penalties (~10% for ML-KEM, higher for stacked algorithms) and offloading bulk encryption to ASICs; telco-scale deployments may favor physical QKD to avoid mass rekeying bottlenecks.
