Copel Boosts Network Security with Juniper Networks Intrusion Detection and Prevention Solution

Juniper Networks IDP 500 Protects the Network from Harmful Traffic

SUNNYVALE, CA - January 25, 2005 - Juniper Networks, Inc. (Nasdaq: JNPR) today announced that Copel, one of the largest Brazilian electric energy companies, is securing its IP/MPLS/Gigabit Ethernet network with Juniper Networks Intrusion Detection and Prevention (IDP) system. This security solution is being provided through Damovo do Brasil, a global services company offering data, mobility and voice solutions.

In April of last year, Damovo was selected by Copel in a public bid to provide Juniper Networks E-and M-series routing platforms for deployment in its new IP/MPLS/Gigabit Ethernet network. As part of its network evolution, Copel is now also implementing Juniper Networks NetScreen-IDP 500 systems to identify and stop network and application level attacks at the edge of the IP/MPLS core before they inflict any damages.

Juniper Networks NetScreen-IDP platforms provide inline attack protection against worms, viruses and Trojans. Using multiple detection methods, Juniper Networks NetScreen-IDP products combine an open signature format with extensive customization capabilities to accurately identify attacks and minimize the number of false positives.

"Copel operates in a highly competitive market, so it is imperative for us to be able to create services based on products that provide high levels of performance, reliability and security," said Carlos Renato de Oliveira Fontes, Telecom Superintendent at Copel.

"We are very proud that Juniper Networks is the supplier for this project," said Tim Lambie, vice president of sales, Americas International, Juniper Networks. "With E- and M-series routing platforms, Juniper Networks IDP systems will offer a secure and assured networking solution for Copel´s customer base."

According to Arnaldo Curvello, President at Damovo do Brasil, Juniper Networks NetScreen-IDP products offer ease of management and prevention capabilities that have exceeded Copel's expectations. "This Damovo solution will enable Copel to protect the network as well as the applications, saving time and money that used to be spent chasing after false threats," added Curvello.
