O Juniper Networks SRX4100-SYS-JB-DC is a high-performance, next-generation Services Gateway designed to deliver advanced security, routing, and VPN capabilities for enterprise branch offices, regional hubs, and service provider edge deployments. As part of Juniper’s SRX4000 Series, the platform combines firewall protection, intrusion prevention, application visibility, and secure connectivity in a compact 1U appliance.
Built on Junos OS, the SRX4100 provides consistent policy management, rich Layer 3 routing features, and advanced security services within a single operating system. The DC-powered variant (–48VDC input) is specifically designed for environments where DC power infrastructure is standard, such as telecommunications facilities and carrier-grade installations.
The SRX4100-SYS-JB-DC supports high firewall throughput, IPsec VPN performance, and scalable session capacity, making it suitable for distributed enterprise networks requiring reliable, secure connectivity between branches, data centres, and cloud environments. With integrated threat protection and unified policy enforcement, it enables organisations to consolidate multiple network and security functions into one resilient platform.
This combination of performance, security depth, and operational simplicity makes the SRX4100-SYS-JB-DC a strong choice for businesses and service providers seeking scalable edge security without compromising reliability or control.
