To address increasing traffic diversity and the growing security demands placed on enterprise networks, Cisco has broadened its market-share-leading portfolio of intrusion prevention systems by announcing the availability of its highest-performing IPS sensor to date, the Cisco IPS 4270. Cisco’s IPS 4270 appliance provides 4-Gbps performance and flexible virtualisation to support data centre, media-rich and transaction-heavy traffic.

This high-performance appliance addresses the security needs of today’s business communications environment and the expanding variety of collaborative applications like voice, video and social networking tools. As high-density traffic loads become increasingly diverse and complex, more powerful and sophisticated intrusion prevention capabilities are required.
The Cisco IPS 4270 handles these performance demands by providing greater throughput without compromising pinpoint traffic inspection. The IPS 4270 offers up to 4Gbps performance for media-intensive environments that feature Web-based content and video.
For networks with heavy transaction-based traffic, such as e-commerce, point-of-sale, instant messaging, and voice over IP, the new appliance provides up to 2 Gbps of throughput and supports as many as 20,000 transactions per second.
All of Cisco’s IPS devices help IT teams detect security vulnerabilities and exploits, respond promptly and precisely, and apply appropriate policies to prevent threats from entering corporate networks. However, the top-of-the-line performance inherent in the Cisco IPS 4270 enables businesses to protect their core enterprise locations with the greatest concentration of traffic.
The IPS 4270 appliance includes redundant, hot-swappable power options and a scalable interface that accommodates high-density copper and fiber Gigabit Ethernet ports. It supports thousands of interfaces for virtual local-area networks (VLANs). It integrates with Cisco’s IPS Device Manager for standalone management.
 For multi-unit deployments, the Cisco IPS 4270 Sensor integrates with Cisco Security Manager and Cisco Security MARS (Monitoring Analysis and Response System) to help ensure collaborative central management across a network security infrastructure.
“Cisco has made a conscientious effort to design a flexible, powerful and virtualisation-friendly IPS device that meets the critical needs of high-traffic environments,” said Mick Scully, vice president of product management for Cisco’s Security Technology Group.
“The IPS 4270 marks a new chapter in both Cisco and the security industry’s evolution toward making intrusion prevention and traffic inspection supportive of networks that feature everything from collaborative Web 2.0 applications to continuous high-density transactions. Simply put, the IPS 4270 has the performance to address today’s real-world enterprise and data centre requirements.”
