SACA - Silicom Accelerated Crypto Adapte
SACA is Silicom’s hardware-accelerated cryptography solution designed to address the growing cost and complexity of security in the post-quantum and AI era.
As AI-driven systems increase data movement, session counts, and encrypted communications, cryptographic workloads become a performance and energy bottleneck.

SACA offloads classical, hybrid, and post-quantum cryptographic operations from the CPU, delivering predictable performance at scale.
It supports PQC algorithms such as ML-KEM and ML-DSA, designed to withstand future quantum threats.
Seamless integration with OpenSSL, NGINX, and Apache allows modern applications to adopt PQC and AI-scale security without redesigning existing software stacks or sacrificing performance.

ThunderFjord FPGA Card
ThunderFjord is Silicom’s high-performance FPGA SmartNIC platform powered by Altera® Agilex™ FPGAs.
It enables programmable, hardware-based acceleration for cryptography, packet processing, and security workloads that are increasingly common in AI-enabled infrastructures, where secure data pipelines must operate at high throughput and low latency.

ThunderFjord provides the hardware foundation for deploying SACA and other security functions directly in the data path, supporting crypto-agile designs that evolve as threats, algorithms, and AI workloads change.

Prominent Case Study

Cybersecurity Case Study - Post-Quantum Cryptography at Scale

Challenge
A major digital infrastructure operator faced a critical bottleneck in its PQC readiness initiative: software-based hybrid and post-quantum algorithms spiked CPU load, threatening latency and operational costs at scale.
ASIC acceleration wasn't viable either-fixed-function silicon can't adapt as PQC standards evolve.

Requirements: Wire-speed performance under heavy PQC workloads, algorithm agility for evolving standards, rapid deployment, and predictable TCO.

Solution
The operator deployed Silicom ThunderBox platforms with ThunderFjord and BlueFjord FPGA SmartNICs (Altera® Agilex™), using SACA for cryptographic offload.

ML-KEM and ML-DSA algorithms were offloaded directly to hardware-eliminating CPU bottlenecks while preserving update flexibility through FPGA reconfiguration.
Seamless OpenSSL integration enabled deployment without application rewrites or workflow changes.

Results:

• Sustained high-throughput encrypted traffic under PQC/hybrid workloads
• Freed CPU resources for other workloads
• Preserved cryptographic agility without ASIC lock-in
• Accelerated deployment vs. custom hardware cycles
