Features + Benefits

Distributed Security Services

The SRX1600 is part of Juniper’s Connected Security Distributed Services Architecture, which removes single points of failure and limitations associated with chassis size and form factor. Scale horizontally and elastically, regardless of form factor, and manage all security services as one logical unit for near-infinite scale without complexity.

AI and Automation

The firewall’s AI Predictive Threat Prevention feature keeps known and zero-day threats off the network at line rate for the entire attack lifecycle, so your network stays safe from initial and subsequent attacks. Automation and a single-policy framework make it easy to configure and manage policies that follow users, devices, and data wherever they go. 

Proven Effectiveness

Juniper Advanced Threat Prevention and intrusion detection/prevention capabilities in SRX Series Firewalls have been proven the most effective for the past four years in objective third-party tests by CyberRatings and others.

Built-In Zero-Trust Security

The SRX1600 features a unique, cryptographically signed 802.1AR-standard device identity (DevID) stored in Trusted Platform Module (TPM) 2.0. The DevID is installed at the time of manufacture to mitigate the risk of hacker spoofing.


EVPN-VXLAN (EVPN Type 5 route) configuration support embeds security across your entire EVPN-VXLAN fabric, from underlay to overlay, everywhere your workloads are.

Easy-to-Use GUI

An on-box GUI includes centralized management for autoprovisioning, firewall policy management, Network Address Translation (NAT), and IPsec VPN deployments.
