Keysight Technologies (NYSE: KEYS) announced the APS-ONE-400, a modular 4x100GE network cybersecurity test platform designed for network equipment manufacturers, service providers, and data center operators.

The appliance fits within a 1 rack unit (RU) footprint and delivers 400 gigabits per second (Gbps) of Layer 4-7 throughput, 380 Gbps of hardware-accelerated encrypted TLS throughput, and 95 Gbps of Elephant Flow throughput. The platform also supports post-quantum cryptography (PQC)-encrypted traffic and Zero Trust Network Access (ZTNA) testing.

When paired with Keysight's APS-M8400 appliance or APS-M1010 management controller, the APS-ONE-400 can generate up to 16 terabits per second (Tbps) of Layer 4-7 traffic, 20 billion concurrent connections, 15 Tbps of TLS traffic, and 25 million TLS connections per second.

The product joins Keysight's existing APS-100/400GE hardware family and is compatible with the APS-M8400, APS-M1010, and APS-ONE-100 platforms. It supports fanout for 100/25/10GE network speeds and can be deployed as a standalone appliance or integrated into existing setups.

Ram Periakaruppan, Vice President and General Manager of Keysight's Network Test and Security Solutions, said the platform emulates "traffic flows associated with generative AI models and agentic applications at hyperscale, including the huge Elephant Flow datasets common to LLM training use cases and PQC-encrypted traffic flows, all in a compact form factor that conserves critical lab resources."

The platform is structured as a "pay-as-you-grow" solution, allowing users to scale capacity over time. According to a press release from the Santa Rosa, Calif.-based company, the design aims to reduce the need for multiple specialized test tools in lab environments.
