PRESS RELEASE

AUSTIN, TX " April 13, 2009 " TippingPoint, a leader in intrusion prevention, today announced availability of its Web Application Digital Vaccine (Web App DV) services, a two-part approach to address the security threat posed by Web applications. This new set of services enables TippingPoint customers to maximize their security investments, while reducing the risk of attacks through custom-built Web applications. Further, the deployment of the Web App DV service allows organizations to show Payment Card Industry Data Security Standard (PCI DSS) compliance while avoiding the pitfalls associated with the ambiguous protection offered by today's Web application firewalls. Today's Web applications are used to support a variety of customer and partner transactions and data exchanges, including inventory management and customer relationship management (CRM). These applications often tie into sensitive data assets such as credit card data or personal information. Prior to being "Webified," these applications were set deep in the confines of the corporate network behind layers of security. Now, these applications are being retrofitted to the Web in order to support a larger audience of customers or partners and have moved closer to the perimeter of the network. "Companies invest a significant amount of money securing various layers of the organization, including the operating system, the network " even the endpoint. However, Web applications " while productive " are still the Achilles heels of most infrastructures," said Rob Ayoub, global program director for network security at Frost & Sullivan. "Since the components of these applications were not originally designed to work together, there are oftentimes weak points associated with the way these are connected. These weak spots represent a greenfield of opportunity for hackers looking to access sensitive data deep in the network." Improving Web Application Protection with Intrusion Prevention Customer feedback indicates that Web application firewalls (WAFs) have had issues with false positives when deployed in-line with the network. Instead of ensuring high availability of the Web applications they were assigned to protect, the firewalls are causing network outages and performance problems. In addition, the constant tuning required to mitigate these false positives adds unnecessary ambiguity to the vulnerabilities the WAFs will ultimately protect against and creates a drain on IT resources and budget. With the TippingPoint Web App DV services, vulnerabilities in customers' custom-built Web applications are identified and remediated with a set of custom DV filters working in tandem with the standard DV filters to provide comprehensive network protection. The service begins with a scan of the application and associated URLs to determine weak points in the code and possible areas that could be exploited by malicious attacks such as SQL injection, cross-site scripting or reverse proxy. Once the scan is completed, the customer works with TippingPoint's DVLabs team to categorize the vulnerabilities by severity and create a custom filter or set of filters that will be deployed through the TippingPoint IPS. "TippingPoint's Web App DV services extend the power of the IPS to capture attacks threatening previously unseen security vulnerabilities," said Rohit Dhamankar, director of TippingPoint's DVLabs. "Adding custom filters to the standard filters already included in the TippingPoint IPS provides our customers with another layer of protection for their corporate assets." Improved PCI Compliance Through Documented Web Application Protection It is now mandatory in the PCI DSS standard for every organization to provide proof that its Web-based applications are protected from malicious attacks. TippingPoint's Web App DV services not only scan these Web applications for dangerous vulnerabilities, but also create custom filter sets that protect the organization's critical assets and meet the standard for PCI compliance. Additionally, as part of the follow-up scan, the protection from these filters is documented in a PCI report, providing clear validation that the identified vulnerabilities have been mitigated. Availability and Pricing The TippingPoint Web App DV Services will be available to customers in May 2009. Customers have the option of utilizing their legacy Web application scanning programs or TippingPoint's Web application scanning service. The TippingPoint Web application scanning service will be offered at a fixed price and will include the initial scan as well as a post-filter scan to ensure accurate blocking. Custom filters will be priced according to volume ordered and will be delivered to the customer within 48-72 hours following the application scan.
