Barracuda Email Gateway Defense is a comprehensive cloud-based email security service designed to protect both inbound and outbound emails from a wide range of threats. This service acts as a filter in front of your hosted email service or servers, safeguarding against spam, viruses, worms, phishing, denial of service attacks, and zero-day threats. The Email Gateway Defense web interface includes a Message Log, which allows users to manage quarantined messages, set account preferences, and create exemption, block, or quarantine policies for email addresses, domains, and users. 

One of the standout features of Barracuda Email Gateway Defense is its ability to provide advanced threat protection. This includes phishing and spam protection, data loss prevention, and email encryption. The system also offers robust administration and user management capabilities, making it easy for IT teams to deploy and manage the service across their organization. Additionally, the service includes features such as inbox filtering, outbound mail protection, and email authentication, ensuring comprehensive email security.

Barracuda Sentinel, now known as Barracuda Impersonation Protection, is another critical component of Barracuda’s email security suite. Sentinel is designed to protect against targeted phishing attacks and email impersonation attempts. It uses artificial intelligence to detect and block sophisticated phishing attacks that traditional email security solutions might miss. When a targeted phishing attack is detected, Sentinel automatically moves the malicious email to the user’s Junk folder, preventing the user from receiving it. This proactive approach helps to safeguard sensitive information and maintain the integrity of your organization’s email communications.
