Advanced Threat Prevention

Bolster your network against evolving threats with Juniper’s Advanced Threat Prevention. A robust suite dynamically adapting to network conditions, it includes malware sandboxing, threat intelligence feeds, and the unique Encrypted Traffic Insights capable of detecting malware concealed in SSL-encrypted traffic.

Next-Generation Firewall Capabilities

Effectively detect and mitigate threats through software-enabled Next-Generation Firewall (NGFW) features. These include intrusion prevention system (IPS), application security (AppSecure), user ID, role-based access controls, and content security (network anti-virus, anti-spam, and advanced Web filtering).

WAN and Wi-Fi Modules

Enjoy flexible, redundant WAN modules encompassing T1/E1, ADSL2/2+, VDSL2, and 3G/4G LTE options. Additionally, the Wi-Fi module introduces 802.11ac Wave 2 wireless LAN access, catering to business users, guests, and Internet of Things (IoT) devices.

Network Segmentation

Tailor security and management policies based on zones, VLANs, and IPsec VPNs. Utilize virtual routers to create internal, external, and DMZ subgroups for enhanced control and security.

On/Off-Box Automation

Leverage on/off-box capabilities for automatic, remote configuration of network and security policies and settings on SRX devices. These features, combined with centralized network security management, simplify IT operations across geographically dispersed locations.

Streamlined Deployment

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