The SRX4100 integrates networking and security into a single platform that provides high-performance, scalable intrusion detection/prevention and dynamically protects against malware. Centrally managed by Juniper Security Director Cloud software, it delivers IPsec VPN, fully automated SD-WAN, and easy policy management capabilities for reliable network security.
Key Features
Firewall performance (max)
40 Gbps
IPS performance
13.9 Gbps
VPN performance

Features + Benefits
Advanced Threat Prevention
Dynamic threat protection with Juniper Advanced Threat Prevention (ATP), including malware sandboxing, threat intelligence feeds, and Encrypted Traffic Insights to detect malware hidden in SSL-encrypted traffic.
Next-Generation Firewall
Detect and mitigate threats using software-enabled NGFW features, including an intrusion prevention system (IPS), application security (AppSecure), user identity services, and role-based access control (RBAC). For content security, the firewall supports integrated network antivirus, antispam, and enhanced web filtering capabilities.
Secure SD-WAN
Unify control of WAN connections across multiple network interfaces while managing and securing MPLS, Internet broadband, and 4G LTE and 5G links.
EVPN-VXLAN
EVPN-VXLAN (EVPN Type 5 route) configuration supported across all Juniper SRX Series Firewalls embeds security across the entire EVPN-VXLAN fabric, everywhere your workloads are.
AI-Predictive Threat Prevention
AI-Predictive Threat Prevention feature keeps known and zero-day threats off the network at line rate for the entire attack lifecycle—not just for 24 hours—helping your network stay safe from initial and subsequent attacks.
Juniper Secure Connect
Our highly flexible SSL VPN and IPsec application provides remote employees with dynamic, adaptive, and secure VPN access to corporate and cloud resources.
On/Off-Box Automation
On/off-box capabilities enable the automatic, remote configuration of network and security policies and settings on SRX firewalls. These automated features combine with centralized network security management to simplify IT operations.
VPN to Public Cloud
The SRX4100 works with the Juniper vSRX Virtual Firewall on Amazon Web Services (AWS) to enable secure VPN connectivity to the public cloud.
99.7% security effectiveness
Juniper received a 99.7% exploit block rate with zero false positives in the CyberRatings.org 2024 Cloud Network Firewall Report.

CUSTOMER SUCCESS
Syntrio delivers fast, secure digital services with Texas friendliness
Santa Rosa Communications first brought phone service to Texas farmers and ranchers in the 1950s. With two acquisitions of wireless companies, Pinnacle Network Solutions, and managed service provider, PCnet, the company exemplifies innovation. Still locally owned and operated, but now called Syntrio, the company serves the digital needs of homes and businesses across North Texas and Southern Oklahoma.
The area, known as Texoma, is attracting residents from the Dallas-Fort Worth area and new businesses. Syntrio, which relies on Juniper Networks® from customer premises to core, is primed for growth.
