How Are You Monitoring the Web Surfing Habits of Your Staff?

Increasingly, it is becoming more important for organizations to have the ability to filter web content so that they can respect their employee's personal interests while decreasing the following risks to their organization:

  • Legal Liabilities - how will you know if an employee engages in an illegal or inappropriate activity? How are you monitoring which websites your employees visit?
  • Bandwidth Consumption - how often has your network connection come to a grinding halt because the person in the office next to yours is downloading music or listening to streaming audio such as an Internet radio station? How are you able to define which websites your employees can or cannot visit?
  • Productivity - do you find that your employees are often distracted by being able to surf the Internet and if so how is your organization able to establish and enforce your Internet usage policy?

3 Modes of Deployment

  1. Inline – Simple and complete – transparent proxy – no config required on the client. Can block Malware protocols.
  2. Forward Proxy – HTTP filtering only – but out of the Data Path. Need to tell the clients to use the Barracuda as proxy.
  3. NEW! WCCP – Requires a Router or Switch that supports WCCP but can proxy to multiple BWF. Load balancing and failover and scalability. Similar to Forward Proxy but the config is on the Swich and not the client.
