Overview
The Juniper Networks SSR120 is a software-driven network appliance that is part of the SSR branch
portfolio. The SSR120 features four 1 GbE ports, two 1 GbE RJ-45/SFP combo ports, 8 GB of memory,
and a 120 GB enterprise-grade solid-state drive (SSD) for storage.
The SSR120 runs the FIPS 140-2 Level 1 compliant Session Smart Router (SSR) software, which provides
secure and resilient WAN connectivity.
The SSR120 appliance is available in models with or without LTE support.
Benefits of SSR120
The SSR120 provides these benefits:
8
•Zero Trust Security (ZTS)—The SSR120 ensures ZTS by authenticating all routes and encrypting all
session traffic. Applications, devices, or users cannot initiate any session that does not comply with the
authentication policies and access rules. The SSR120 supports session Layer 2 through Layer 5 stateful
firewall functions, including DoS/DDoS protection, NAT, encryption, VPN, and traffic filtering.
•Adaptive encryption—The SSR120 automatically detects traffic encrypted using HTTPs or IPSec and
does not reencrypt such traffic. This capability results in improved performance and reduced overhead
due to double encryption.
•Multipath routing and failsafe service delivery—Application and policy-based multipath routing, intelligent
path monitoring, and application delivery capabilities with no loss ensure that application traffic is
optimized across multiple paths and delivered despite failures.
•Wireless WAN support—In addition to Ethernet connections, Wireless WAN support through the LTE
module provides more flexibility in deployments.
SSR120 Models
The SSR120 is available in three different models, with or without LTE support.
NOTE: To use the SSR120 appliance, you must purchase the SSR software subscription license
sold separately.
