Barracuda Web Application Controllers protect your Web site from attackers leveraging protocol or application vulnerabilities to instigate unauthorized access, data theft, denial of service or defacement of your Web site. Unlike traditional network firewalls or intrusion detection systems that simply pass HTTP, HTTPS or FTP traffic for Web applications, Barracuda Web Application Controllers proxy this traffic and insulate your Web servers from direct access by hackers. Comprehensive Website Protection As a full proxy, Barracuda Web Application Controllers inspect both request and response traffic, providing the capabilities to not only block inbound attacks, but also to cloak your Web site from hackers and filter outbound traffic to prevent potential sensitive data leakage, such as credit card numbers or Social Security numbers. In addition, Barracuda Web Application Controllers secure applications from unauthorized user access through integration with common authentication services, such as LDAP and RADIUS servers, and can provide full PKI infrastructure for use with client certificates. Advanced Traffic Management & Acceleration The Barracuda Application Gateway integrates traffic management capabilities, including caching, compression and load balancing. With the Barracuda Application Gateway, you can not only secure your Web applications but increase both their performance and availability as well. A Single Solution to a Multifaceted Problem Online Web-based applications are increasingly at risk from professional hackers who target such applications in order to commit data theft or fraud. Being compromised can damage an enterprise's reputation, result in loss of customers and impact the organization's bottom line. In addition, companies that transact online are faced with a host of growing industry regulations such as the Payment Card Industry Data Security Standard (PCI DSS), which mandates that all enterprise and Web applications handling credit card and account information must undergo an extensive and costly audit of custom application code. The alternative to satisfy PCI DSS compliance is simply installing a Web application firewall. The combination of these factors along with banking industry PCI DSS compliance concerns, creates demand for a more technologically and cost-effective risk protection solution for online Web applications. Barracuda Web Application Controller Features Traditionally, security has been considered a network issue, where system administrators lock down host computers through a network firewall. While a typical network firewall can help restrict traffic to HTTP, HTTPS and FTP, this traffic can contain command exploits leveraging vulnerabilities in the Web application itself that can result in unauthorized access, data leakage, site defacement and other attacks by hackers that compromise both the privacy and integrity of vital data. Businesses of all sizes that operate their own Web applications should ensure that their Web sites are protected against application vulnerabilities. Barracuda Web Application Controllers, including both the Barracuda Web Application Firewall and Barracuda Application Gateway, provide complete protection of Web applications and are designed to enforce policies for both internal and external data security standards, such as the Payment Card Industry Data Security Standard (PCI DSS). At the same time, the Barracuda Application Gateway features a number of additional traffic management capabilities designed to improve the performance, scalability and manageability of today's most demanding data center infrastructures.
