BCS Subscription – Robust DNS Filtering

A BCS subscription offers DNS filtering to provide protection from online threats such as viruses, ransomware, phishing attacks, and botnets by blocking endpoint communication to websites that host malicious content. By enforcing policy at the DNS level, you block access to the sites before that connection is made, preventing dangerous communication between endpoint and website. 

Key Features

  • The setup is quick and easy, taking less than a minute. There is no hardware or software to install.
  • 'Agentless' DNS protection for all devices that sit behind your customers’ router or firewall — which is critical as IoT devices become more common in today’s workplaces.
  • Web security and content filtering configured and managed in the cloud
  • Blocks malicious sites before a connection is established, on all devices in the network
  • Helps enforce customers’ company policies by restricting inappropriate web browsing
  • Offers customizable protection levels and templates that can be reused
  • Optional export of log information from BCS Plus to your custom logging server using the Syslog feature
  • Powered by Barracuda’s real-time threat intelligence network
