Secure SD-WAN

Unifies control of WAN connections across multiple types of network interfaces while managing and securing MPLS, broadband, and 4G LTE links

Juniper Mist WAN Assurance

Simplifies operations, provides visibility into end-user experiences with application-based context, and shortens WAN mean time to repair (MTTR).

Advanced Threat Prevention

Protect your network against the latest threats with Juniper Advanced Threat Prevention. Our rich suite of security capabilities that adjust dynamically to network conditions provides malware sandboxing, threat intelligence feeds, and Encrypted Traffic Insights, a feature able to detect malware hidden in SSL-encrypted traffic.

Next-Generation Firewall

Detect and mitigate threats through software-enabled next-generation firewall (NGFW) features, including intrusion prevention system (IPS), application security (AppSecure), user ID and role-based access controls, and content security (network anti-virus, anti-spam, and enhanced Web filtering).

WAN and Wi-Fi Modules

Flexible, redundant WAN modules include T1/E1, ADSL2/2+, VDSL2, and 3G/4G LTE options. The Wi-Fi module offers 802.11ac Wave 2 wireless LAN access for business users, guests, and IoT devices.

Network Segmentation

Enables you to tailor security and management policies based on zones, VLANs, and IPsec VPNs and to use virtual routers to create internal, external, and DMZ subgroups.

On/Off-Box Automation

On/off-box capabilities enable the automatic, remote configuration of network and security policies and settings on SRX devices.

These automated features combine with centralized network security management and maintenance to simplify IT operations across geographically dispersed locations.

Simple Deployment

Zero-Touch Provisioning (ZTP) simplifies initial deployments in branches where IT resources may be limited or unavailable.
