Two Subscription Levels Compared
Barracuda Content Shield (BCS) and Barracuda Content Shield Plus (BCS Plus) subscription levels are compared in this table. Details about each subscription type are listed below.

BCS Subscription – Robust DNS Filtering
A BCS subscription offers DNS filtering to provide protection from online threats such as viruses, malware, 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
