SUNNYVALE, Calif., Nov. 19 /PRNewswire-FirstCall/ -- Blue Coat Systems, Inc. , a leader in WAN Application Delivery and Secure Web Gateway, today announced that Banco Nacion of Argentina, the country's foremost bank with 643 sales points and 563,000 customers, has selected Blue Coat(R) ProxySG(R) appliances to provide Web security and policy control across the bank's Internet gateway to protect its internal network and enable it to comply with bank and credit card regulations. In addition, the bank was able to accelerate software applications and reduce bandwidth consumption across its Internet Gateway up to 66 percent.

The implementation of the Blue Coat appliances provides a new level of security and control for the bank's network. One of the most important requirements for selecting a solution was that security capabilities did not impede performance. The ProxySG appliances actually enhance performance.

The Banco Nacion of Argentina is a consumer lending institution that has just taken steps to elevate its Web control policies. Blue Coat ProxySG appliances allow them to protect against spyware, Web-borne viruses and malicious code. In addition, the appliances enable the bank to manage various Web applications -- such as instant messaging, peer-to-peer file sharing and streaming media -- to ensure available bandwidth for business critical uses and to comply with requirements and bank policies. Banco Nacion can enforce Web acceptable use practices for employees and provide the logging and reporting it needs for audits and controls. ProxySG appliances can perform all of these functions while also accelerating acceptable content and applications and reducing bandwidth consumption.

"Using Blue Coat's appliances Banco Nacion has improved and standardized its Internet access platform with the controls and protection it needs to run its business," Hector Nevares, IT Manager of Banco Nacion of Argentina. "Protecting customer data and complying with banking regulations is essential and can be accomplished without impeding the speed of operations."

"Blue Coat ProxySG appliances combine security, policy control and acceleration within the same platform," said Alejandro Viola, a Blue Coat Territory Manager in South America. "With Blue Coat appliances, Banco Nacion does not have to choose between security, control or performance."
