VIAVI Launches CyberFlood CF1000 — A Native 400G Platform for Validating Multi-Terabit Security and AI Data Centre Infrastructure
The hyperscale data centres and high-speed networks powering today's AI workloads operate at a scale and complexity that traditional security and performance testing tools were never designed to handle. Encrypted traffic volumes have exploded. AI inference fabrics now sit alongside NGFWs, ADCs, and zero-trust architectures in the same infrastructure stack. Quantum-safe cryptography is moving from a future concern to an immediate deployment requirement. Yet the testing platforms charged with validating all of this have largely remained anchored to speeds and scenarios that belonged to a previous era. VIAVI Solutions Inc. (NASDAQ: VIAV) has launched the CyberFlood CF1000 Appliance — a native 400G security and application performance test platform that brings all of these validation challenges together in a single, compact system built for the multi-terabit demands of modern AI data centre infrastructure.
Developed for network equipment vendors, hyperscale data centre operators, and service providers, the CF1000 delivers OSI Layer 4-7 validation of critical infrastructure under real-world encrypted and dynamically mixed traffic conditions — eliminating the validation gaps that have made traditional test systems inadequate for the environments organisations are building today. The global network security market is projected by the Dell'Oro Group to exceed $30 billion in 2026, driven by Zero Trust deployments, AI workloads, and continuing cloud expansion. The CF1000 is built for the validation demands that growth creates.
"The move to ultra high-speed, highly secure AI networks has fundamentally changed the way security and performance must be validated. The challenge has intensified as organizations build infrastructure to enable the agentic era, which require that quantum security, AI inference workloads and AI-enabled security policies all work seamlessly together. CF1000 delivers the performance and realism customers need to validate modern data center infrastructure and security architectures, while helping them reduce validation timelines, optimize infrastructure decisions and accelerate deployments."

Why Traditional Security Testing Has Failed to Keep Pace
The infrastructure that modern organisations are deploying — and that their security teams are responsible for validating — has changed fundamentally over the past three years. The combination of ultra-high-speed networking, end-to-end encryption, AI inference workloads, and emerging quantum-safe cryptography requirements has created a validation challenge that sits well beyond what legacy test platforms were built to handle.
Traditional test systems address one or two of these dimensions in isolation. They can generate high volumes of traffic, or emulate threats, or test TLS performance — but rarely all at once, and rarely at the speeds that multi-terabit data centre infrastructure actually operates. The result is a validation gap: organisations deploy security infrastructure they believe has been tested, only to discover under real-world conditions that the testing never reflected the environment it was meant to represent.
The CF1000 was built specifically to close that gap — bringing together, on a single platform, the full set of validation capabilities that today's infrastructure actually demands.
Four Unified Validation Capabilities on a Single Platform
The CyberFlood CF1000 eliminates the need to stitch together multiple test systems by consolidating four critical validation capabilities into one appliance:
Massive-Scale Encrypted Traffic Generation
The CF1000 delivers industry-leading TLS performance — supporting more than 500Gbps of encrypted throughput and up to 800,000 TLS v1.3 connections per second. This level of encrypted traffic generation allows security teams to validate NGFWs, ADCs, VPN gateways, and zero-trust architectures under conditions that closely replicate what those systems will face in production — not sanitised test scenarios that understate the actual load.
Continuous Threat Vector Emulation
CF1000 runs continuous threat vector emulation alongside live application traffic — not as a separate test pass, but simultaneously, reflecting how attacks are actually launched against operational systems. This enables OSI Layer 4-7 validation of DDoS mitigation systems, NGFW detection capabilities, and AI-enabled security policies under the dynamic, mixed-traffic conditions that static test scenarios consistently fail to capture.
Quantum-Safe Cryptography Validation
Post-quantum cryptography is no longer a future consideration — standards are being finalised and deployment timelines are compressing. The CF1000 provides dedicated quantum-safe cryptography validation, enabling network equipment vendors and operators to test their infrastructure against the cryptographic requirements of the emerging quantum era before they become operational obligations rather than planning considerations.
AI Inference Traffic Emulation at Terabit Scale
CF1000 extends the CyberFlood platform with highly scalable AI inference traffic emulation — enabling realistic testing of large language model performance and AI-driven application workloads at terabit scale. This allows hyperscale operators and service providers to evaluate end-to-end AI inference infrastructure and LLM application performance, and to assess the critical trade-offs between cost efficiency and user experience before infrastructure decisions are locked in.
Hardware That Matches the Problem — The 2RU CF1000 Appliance
The CF1000 Appliance delivers all of these capabilities in a compact 2RU form factor — housing four 400G OSFP ports and eight 100G QSFP28 ports. This configuration enables up to 1.2Tbps of real-world application traffic testing without requiring an external switching infrastructure, dramatically simplifying the test environment and reducing the total cost and complexity of validation at scale.
The native 400G architecture is the key distinction from previous-generation platforms. Where earlier CyberFlood configurations required external switching to aggregate ports and reach these speeds, the CF1000 achieves 400G natively — making it possible to run high-fidelity, real-world traffic and attack emulations directly, without the latency, complexity, and cost of the additional infrastructure those configurations demanded.
The global network security market is projected to exceed $30 billion in 2026, with growth driven by Zero Trust initiatives, AI workloads, and continuing cloud expansion. Platforms that can validate security infrastructure under real-world AI and encrypted traffic conditions will be central to how organisations make infrastructure decisions as that market accelerates.

Who CF1000 Is Built For — and What It Validates
The CF1000 is designed for the organisations that build, operate, or certify the security and AI infrastructure that enterprises depend on. Three distinct customer segments are the primary targets:
Validating that NGFWs, ADCs, DDoS mitigation systems, and AI inference hardware perform to specification under real-world mixed-traffic and attack conditions before shipment.
Evaluating AI inference infrastructure and LLM application performance at terabit scale — and assessing cost-efficiency versus user-experience trade-offs before infrastructure commitments are made.
Validating zero-trust architectures, VPN gateways, and quantum-safe cryptography deployments under the encrypted traffic volumes and dynamic conditions that operational networks actually generate.
Key Takeaways
VIAVI Solutions' CyberFlood CF1000 is a native 400G security and application performance test platform — purpose-built to validate multi-terabit security and AI data centre infrastructures under real-world encrypted and dynamic mixed-traffic conditions.
By unifying encrypted traffic generation, threat vector emulation, quantum-safe cryptography validation, and AI inference traffic emulation on a single platform, CF1000 eliminates the validation gaps that traditional test systems leave open — and does so at up to 1.2Tbps in a compact 2RU form factor.
The platform's AI inference traffic emulation enables realistic testing of LLM performance and AI-driven application workloads at terabit scale — allowing hyperscale operators to evaluate cost-efficiency versus user-experience trade-offs before infrastructure decisions are locked in.
Industry-leading TLS performance — 500Gbps+ encrypted throughput and 800,000 TLS v1.3 connections per second — makes CF1000 the benchmark for validating the encrypted infrastructure demands of both agentic AI deployments and emerging quantum-safe cryptography requirements.
The CyberFlood CF1000 arrives at exactly the right moment in the market's evolution. As network equipment vendors, hyperscale operators, and service providers build out the infrastructure that will support the agentic AI era, the validation gap between what they are deploying and what their test tools can actually assess has become operationally consequential. VIAVI's answer — a single platform that handles encrypted traffic, threat emulation, quantum-safe cryptography, and AI inference validation at 400G natively — is the closest thing the industry has to a test platform that matches the ambition of the infrastructure it is meant to certify.
