Company Description

Juniper Networks was founded in February 1996 and became publicly traded in 1999. Headquartered in Sunnyvale, Calif., the networking and security vendor has almost 10,000 employees, 92 offices in 43 countries and annual revenues of just under $5 billion.

Product Description

Juniper is considered by Gartner among the Niche Players. The Juniper Networks SRX Series Services Gateways adapt as new threats emerge, using information from Juniper Sky Advanced Threat Prevention cloud-based service and third-party GeoIP feeds to block malicious activities as they enter or traverse the network. They provide application visibility and control, IPS, and user-based application policies, plus unified threat management (UTM) to protect and control business assets. The gateways can also perform deep-packet inspection (DPI) and apply role-based access policies.

"Juniper's commitment to open and scalable standards enables users to leverage custom and third-party feeds for flexibility and customized firewall policies to defend against the broadest spectrum of threats," said Mihir Maniar, vice president of security product management, Juniper Networks. "It also reduces the operational burden by dynamically incorporating security intelligence into the firewall policy."
