F5's TrafficShield® Web Application Firewall is Now Available on Powerful TMOS Architecture

F5 Networks, Inc. (NASDAQ: FFIV), the global leader in Application Delivery Networking, today announced that it has delivered yet another product on its industry-leading TMOS architecture. TrafficShield® is a web application firewall that provides comprehensive, proactive, network and application-layer protection from generalized and targeted attacks. Now, F5 customers can achieve state-of-the-art application security through the TrafficShield product, available as a stand alone solution on TMOS, or through the BIG-IP Application Security Module (ASM), which is a software solution that runs on the BIG-IP v9 system.

Integrated with F5's TMOS architecture, the new TrafficShield product can now leverage many of the pre-existing capabilities of the TMOS operating system. Some of the most popular TMOS features and capabilities leveraged include:

SSL Acceleration

TMOS enables TrafficShield to more efficiently process SSL traffic. SSL key exchanges, certificate management and AES encryption are processed through the TMOS architecture while extending the capability of TrafficShield.

iRules Support

This scripting language gives IT professionals unparalleled application awareness and network control. For example, administrators can build an iRule to scrub sensitive information from servers such as credit card numbers, social security numbers, or any text pattern--protecting against disclosure, fines, and damage to business reputation.

Client Authentication

LDAP, RADIUS, TACACS+, Client Certificate-based LDAP and OCSP authentication profile types are now supported on TrafficShield, providing much greater flexibility in authentication integration within different customer environments.

Packet Filtering

Another capability made possible by TMOS, packet filtering enables TrafficShield to identify and filter traffic at the packet level, providing exhaustive security at both the network and application layers.

TCP Stack Optimization

With TrafficShield on TMOS, end users can also enjoy the advantages of F5's highly optimized TCP stack, reducing the effects of chattiness, congestion, and packet loss recovery that all lead to application latency.

Seamless Network Integration

TMOS enables TrafficShield to leverage many of the trusted basic network functions delivered by F5 such as VLAN support, routing and robust failover capabilities. More flexible integration into the network fabric and maximized uptime of application firewalls are all part of the benefits of TrafficShield running on TMOS.

"TrafficShield running on TMOS represents a strategic leap forward in stand-alone web application firewall technology," said Jason Needham, Director of Product Management at F5 Networks. "The marriage of an enterprise-class web application firewall with the market leading application proxy offers a new level of security and reliability. TMOS is truly unique in that it is an intelligent, modular and scalable operating system that can immediately enhance the product functionality that sits on top of it."


F5 TrafficShield on the TMOS platform will be available in February. For more information, visit
