Juniper Networks, Inc. is an American manufacturer of networking equipment founded in 1996. It is headquartered in Sunnyvale, California, USA. The company designs and sells high-performance Internet Protocol network products and services. Juniper’s main products include T-series, M-series, E-series, MX-series, and J-series families of routers, EX-series Ethernet switches and SRX-series security products. Junos, Juniper’s own network operating system, runs on most Juniper products.
SSG Series (short for Secure Services Gateway) is a line of firewall products running ScreenOS by default. These devices offer basic routing, IPSec and UTM functionality out of the box but do not have the same advanced management capabilities that other devices running JunOS have. While some of the more expensive SSG firewalls have a supported upgrade path to JunOS, many of the low end models can only run ScreenOS.
SRX Series Dynamic Service Gateways is a series of security services devices running Junos. Security features include the full UTM functionality previously found on ScreenOS, including web filtering, IDP and anti-virus. Although high-end and low-end SRX platforms differ in the underlying hardware, common software base enables feature consistency and signature Juniper routing code.
Juniper Secure Access products provide SSL-based VPN services to remote users through regular web browsers (e.g. Mozilla Firefox) on a variety of Java-enabled platforms (Microsoft Windows, Mac OS, Linux, Apple iOS). This product line came to Juniper from NetScreen via last-minute acquisition of Neoteris and became one of the company’s technological wins. Unlike legacy IPsec tunnels, basic SSL VPN access works right out of the box on virtually any SSL-capable device (e.g. iPhone with mobile Safari browser) without a specialized client.
NSM Network and Security Manager is an enterprise-wide management tool for Juniper devices that features single-point bastion control over multiple Juniper devices, a syslog host and configuration backup repository, and the NSMXpress appliance that provides distributed hierarchical features.
