Cisco IronPort Web Data Security and Data Loss Prevention
Data security and data loss prevention (DLP) is a serious issue for companies, as the number of incidents – and the cost to those experiencing them – continues to increase. Whether it’s a malicious attempt, or an inadvertent mistake, data loss can diminish a company’s goodwill and reputation, reduce shareholder value, introduce legal liability, and put individuals and organizations at risk of financial theft. As a leader in web security, Cisco® understands the complexities of creating a solution to address one of the most significant vectors for data loss: ubiquitous Internet access. Across all key network protocols, an intelligent, high-performance data security and DLP solution for the web and web applications is a must-have for today’s organizations. Decision makers should look to vendors like Cisco with deep expertise in security and content scanning and select a best-of-breed solution that includes data security and DLP technologies – including integrating with external DLP solutions to enforce policies.

“The increased use of Web 2.0 technologies such as blogs, social networking, and consumer-grade instant messaging increases the speed with which information moves outside of the enterprise.”
– Andrew Jaquith, Senior Analyst Forrester Research

Data-stealing malware presents a real and imminent threat to business today, and is the starting point for any discussion on data security for the web. The Cisco IronPort web security appliance provides the best protection against data-stealing malware, using Cisco IronPort Web Reputation Filters, the Cisco IronPort Dynamic Vectoring and Streaming (DVS) engine and the Layer 4 Traffic Monitor (L4TM). These technologies prevent Trojans and other malicious applications from entering the network, while blocking the “phone home” data connections from existing malware. The data loss problem extends well beyond malware. Employees can easily use webmail to send a message including proprietary information, post confidential data on social networks and blogs, or transfer financial documents over FTP to a server outside the corporate network. Making sure that sensitive data does not leave the corporate boundary – while allowing users to leverage the full power of the Internet – is an important and challenging issue to solve.
