Cisco IOS Content Filtering is a Web security solution that helps organizations protect against known and new Internet threats, improve employee productivity, and enforce business policies for regulatory compliance.
Cisco IOS Content Filtering is ideally suited for small medium businesses and enterprise branch offices that need a scalable, low-maintenance solution.
As employees surf the internet, they expose themselves to websites that are known to give out malware, adware, spyware, and phishing. This not only causes downtime, but also revenue losses. According to an Infonetics Research (2006), nearly 2 percent of revenue losses and 51 percent of downtime costs are due to security costs.
Deployed on Cisco® integrated services routers, Cisco IOS Content Filtering offers category-based productivity and security ratings. Content-aware security ratings protect against malware, malicious code, phishing attacks, and spyware. URL and keyword blocking help to ensure that employees are productive when accessing the Internet. This is a subscription-based hosted solution that leverages Trend Micro's global TrendLabs™ threat database, and is closely integrated with Cisco IOS.
The Cisco IOS Content Filtering solution reduces network complexity by eliminating the need for a standalone content filtering product. Cisco ISR customers are not required to purchase and manage additional hardware for web filtering which reduces both capital and operational expenses for the organization.
It interoperates with other Cisco IOS Software components such as Cisco IOS Firewall, Cisco IOS IPS, VPN functions, and per-user authentication and authorization to provide outstanding value and benefits:
• Improves employee productivity and reduces organizational risk: Cisco IOS Content Filtering helps organizations restrict Internet use that exposes them to risks such as inappropriate use of company resources, legal liability, and productivity losses.
• Prevents malware exposure: Cisco IOS Content Filtering blocks users from accessing Websites that are known to dispense malicious code (key loggers, adware, Trojans, spyware, phishing, etc.).
• Enforces compliance: Regulations such as the Health Insurance Portability and Accountability Act (HIPAA), Federal Information Security Management Act (FISMA), and Children's Internet Protection Act (CIPA) mandate reliable content filtering. Cisco IOS Content Filtering uses industry-leading technology validated by TrendMicro's TrendLabs™, a global network of research centers committed to constant threat surveillance and attack prevention.
• Conserves network resources: Cisco IOS Content Filtering enables an organization to set security policies that limit Internet access. This prevents bandwidth-intensive applications and malware from being downloaded, thereby protecting network resources.
• Eases provisioning and management: Easy-to-use Web-based Cisco Configuration Professional enables rapid deployment of Cisco IOS Content Filtering registration and policies.
