Imperva Introduces First Network Adaptive Web Application Firewall; SecureSphere Web Application Firewall Eliminates Network Modifications with Support for All Leading Deployment Modes.FOSTER CITY, Calif. -- Imperva(TM), the leader in data security for the data center, today announced the first web application firewall that eliminates the need for organizations to reconfigure their networks by adapting to existing infrastructures. The new version of Imperva's SecureSphere Web Application Firewall supports four deployment modes - bridge, router, proxy, or sniffing - to allow seamless and transparent coexistence in any IT environment. Competing web application firewalls impose complex integration challenges by offering just one or a limited number of deployment options. Flexible and Adaptive Deployment For transparent integration with any IT environment, SecureSphere can be deployed in bridge, router, proxy, or network monitoring The term network monitoring describes the use of a system that constantly monitors a computer network for slow or failing systems and that notifies the network administrator in case of outages via email, pager or other alarms. mode. This flexibility eliminates the need for organizations to adapt their infrastructure in order to accommodate a security appliance Security appliances protect computer networks from unwanted data traffic, intruders, email spam, enforce policies, and may also be used to create and manage VPNs. There are a number of types of security appliances. . By offering the broadest range of deployment options, SecureSphere enables customers to choose the least intrusive and most effective approach based on their existing architecture. Each deployment mode is best suited to a different set of network requirements. For example: --Bridge: this mode is as transparent as deploying a layer 2 switch on the network, offers high performance, and requires no changes to web applications or the network --Router: this mode is best if Network Address Translation (NAT (Network Address Translation) An IETF standard that allows an organization to present itself to the Internet with far fewer IP addresses than there are nodes on its internal network. ) is required, or if web server IP addresses are in a different subnet (SUBNETwork) A logical division of a local area network, which is created to improve performance and provide security. To enhance performance, subnets limit the number of nodes that compete for available bandwidth. than the rest of the network --Proxy: provides a seamless option for replacing an existing application proxy See proxy server. with Imperva's Web Application Firewall --Network monitoring (sniffing): This mode is ideal for testing purposes, since the appliance is not inline and does not impact the network "Customers have told us that they want their Web application firewall to adapt to their network and not their network to have to adapt to a firewall," said Alan Norquist, vice president of marketing for Imperva. "By offering the broadest and most flexible range of deployment options available today, SecureSphere eliminates a major roadblock for organizations that have delayed web application firewall deployments due to network configuration challenges." Increased Performance and Availability In addition to its flexible new deployment options, SecureSphere now meets the performance and high availability Also called "RAS" (reliability, availability, serviceability) or "fault resilient," it refers to a multiprocessing system that can quickly recover from a failure. There may be a minute or two of downtime while one system switches over to another, but processing will continue. requirements of the most demanding web environments. For high transaction applications, SecureSphere is available on the G16 appliance platform which provides 2Gbps of throughput. SecureSphere also supports advanced failover using VRRP (Virtual Router Redundancy Protocol) A protocol for switching to a backup router in the case of failure. Two or more routers are set up with VRRP, and one is elected the "master. for layer 3 and above deployments, and the proprietary Imperva High Availability (IMPVHA) protocol for layer 2 applications. Integration with Crossbeam UTM (Unified Threat Management) Refers to a stand-alone appliance or a software package that combines a firewall, antivirus, spam and content filtering as well as intrusion detection. See firewall, antivirus, antispam and IDS. Appliance Finally, to meet the requirements of carrier networks and large scale data centers, Imperva and Crossbeam have partnered to offer the SecureSphere web application firewall as a blade on the Crossbeam X-series Unified Threat Management See UTM. platform. The availability of SecureSphere on the Crossbeam platform reduces hardware deployments and centralizes application protection with other security services such as anti-virus and VPN (Virtual Private Network) A private network that is configured within a public network (a carrier's network or the Internet) in order to take advantage of the economies of scale and management facilities of large networks. on a single the cost-effective, high performance, and scaleable chassis. Pricing and Availability Version 4.2 of the SecureSphere Web Application Firewall is available immediately from Imperva and its business partners worldwide. Pricing starts at $30,000 USD USD In currencies, this is the abbreviation for the U.S. Dollar. Notes: The currency market, also known as the Foreign Exchange market, is the largest financial market in the world, with a daily average volume of over US $1 trillion. .
