Check Point Quantum Security Gateway QLS-20400 Expansion Line Card (2x 100GbE QSFP28)

The Check Point Quantum Security Gateway QLS-20400 Expansion Line Card is a high-density 100GbE interface module designed for the Quantum Security Gateway QLS-20400 appliance. This expansion card provides two QSFP28 ports operating at 100 Gbps per port, enabling 200 Gbps of aggregate throughput capacity. The module integrates seamlessly with the QLS-20400 chassis architecture to support backbone network connectivity and ultra-high-speed data center deployments.

This line card addresses enterprise requirements for sustained throughput scaling in security-critical network segments. The dual 100GbE interface design enables organizations to aggregate multiple security services—including threat prevention, deep packet inspection, and policy enforcement—without introducing throughput bottlenecks at core infrastructure layers. QSFP28 optical transceiver compatibility supports both direct-attach copper (DAC) and long-reach single-mode fiber (SMF) interconnection topologies.

Deployed in Quantum Security Gateways, the QLS-20400 expansion card delivers stateful firewall, IPS/IDS, and application-layer security services at line rate across 100GbE networks. The module is engineered for continuous operation in data center environments supporting carrier-grade availability and security orchestration workflows.

Ideal for

• Data center backbone firewall throughput expansion for multi-tenant cloud infrastructure
• High-frequency trading environments requiring sub-microsecond latency and lossless packet forwarding at 200 Gbps aggregate
• Service provider core network security consolidation with unified threat prevention across 100GbE subscriber aggregation points
• Enterprise WAN edge security upgrade for organizations migrating from 40GbE to 100GbE fabric architectures
• Government and financial sector secure network segments mandating FIPS-validated encryption and audit logging at line rate
• Internet exchange point (IXE) DDoS mitigation and threat defense infrastructure requiring multi-port 100GbE inspection
