PCIe-based hardware acceleration platform that offloads transport optimisation, inline compression/deduplication and cryptographic workloads from host CPUs to enable deterministic, line-rate encrypted data movement for cloud, AI, enterprise, defence and sovereign environments. Modular architecture with flow- and congestion-aware transport acceleration, AES/TLS/IPsec crypto (post-quantum roadmap), secure boot/hardware root-of-trust and firmware integrity for high-assurance, power-efficient deployments.
