VIAVI has launched the CyberFlood CF1000 Appliance, a native 400G security and application performance test platform aimed at validating multi-terabit security and AI data center infrastructure at scale. The system targets OSI Layer 4-7 testing under encrypted and mixed-traffic conditions for network equipment vendors, hyperscale operators, and service providers.

The CyberFlood CF1000 Appliance is a 2RU platform with four 400G OSFP ports and eight 100G QSFP28 ports. VIAVI lists the system’s traffic generation capacity at up to 1.2 Tbps of real-world application traffic testing without requiring external switching infrastructure.

On the encrypted-traffic side, the CF1000 supports Transport Layer Security (TLS) testing with more than 500 Gbps of encrypted throughput and up to 800,000 TLS v1.3 connections per second. It also adds quantum-safe cryptography validation, positioning the box for operators and vendors trying to validate encryption-heavy designs as link speeds push to 400G and beyond.

For AI infrastructure validation, CF1000 extends CyberFlood with AI inference traffic emulation intended to test large language model (LLM) performance and AI-driven application workloads at terabit scale. In practice, that’s about pressure-testing end-to-end inference paths—security devices, application infrastructure, and the network behavior between them—under traffic patterns that look less like uniform throughput tests and more like what inference services actually generate.

One practical implication: collapsing high-rate encrypted traffic generation, threat vector emulation, and AI inference traffic emulation into a single 2RU platform can simplify lab setups where “realism” often gets traded away for manageable test topologies. But the usefulness will come down to how closely the emulated mixes match production traffic profiles and how repeatable those tests are when teams are tuning policies, load balancers, and security controls at the same time.

Mauricio Sanchez, Senior Director, Enterprise Security and Networking at Dell’Oro Group, said, “As networks move toward 400G and higher speeds, the combination of encrypted traffic, AI‑driven workloads and distributed cloud architectures is raising the bar for security performance validation. Platforms that can realistically test security and application infrastructure at scale are becoming an essential part of how vendors and operators reduce risk and confidently deploy next‑generation networks.”

VIAVI’s Sashi Jeyaretnam, Senior Director, Security Product Management, said, “The move to ultra high-speed, highly secure AI networks has fundamentally changed the way security and performance must be validated,” adding that CF1000 is intended to help customers “reduce validation timelines, optimize infrastructure decisions and accelerate deployments.”

CyberFlood is part of VIAVI’s test and measurement portfolio for validating security and application performance in modern networks.
