Link-Security™ Software is a software product from Napatech that offloads TLS encryption and decryption workloads from the host CPU to a Data Processing Unit (DPU). By moving cryptographic operations off the CPU, it enables high-performance TLS processing without consuming host CPU resources. The software is part of Napatech's broader Link Software family, which includes products for packet capture, inline processing, virtualization, storage, and programmable FPGA deployments. Link-Security™ is designed for cloud, enterprise, and telecom datacenter environments where network performance and resource efficiency are critical. The product operates in conjunction with Napatech's FPGA-based SmartNIC and DPU hardware platforms, enabling offloaded security workloads at line rate. It is listed alongside other Link Software packages on the Napatech products page, with a dedicated product page available for more detailed specifications.
