Tele2 Zakelijk Secures Customers' Networks with Juniper Networks High-Performance Managed Security Solutions

New Managed Security Suite Delivers a Differentiated and Fully Managed Security Service to Enterprise Customers Based on Juniper Networks UTM Solution

AMSTERDAM and SUNNYVALE, Calif., November 21, 2007 - Juniper Networks, Inc. (NASDAQ: JNPR), the leader in high-performance networking, and Tele2 Zakelijk, Telecom operator for the business market in the Netherlands, today announced that Tele2 Zakelijk has launched a new managed security service for the Dutch enterprise market based on Juniper Networks integrated firewall solutions. This managed security service offers customers protection against a broad array of threats while maintaining very high network performance.

The managed security service is based on Juniper Networks Secure Services Gateway (SSG) platforms to deliver the high-performance, security and LAN/WAN connectivity required by today's innovative businesses. In addition to performing stateful firewall functions, the SSG platforms protect inbound traffic flows from worms, spyware, Trojans, and malware with a comprehensive set of optional Unified Threat Management security features that include intrusion prevention, antivirus, anti-spam and web filtering.

"The network is a critical business asset for enterprises of any size, but the risk posed to valuable data and applications by hackers, viruses and other malware can be counter-productive," says Bram Smits, director business markets at Tele2 Zakelijk. "With Juniper's SSG security platforms we can offer customers a managed security service that secures customer networks against a broad array of threats while maintaining very high network performance. Our customers can now choose from a wide variety of business Internet products from Tele2 Zakelijk with a comprehensive security solution at a competitive price."

"A fully managed, integrated security environment is very attractive for many enterprises," said David Small, vice president of channels, EMEA at Juniper Networks. "Tele2 Zakelijk has vast experience in offering managed services, and with the introduction of the Managed Security Suite, it is continuing to anticipate the market's needs as threats proliferate and become more sophisticated. We're very pleased that Tele2 Zakelijk has chosen to roll out new managed services based on Juniper's high-performance security platforms."
