Sentinel is deployed directly into Office 365, allowing it to use machine learning algorithms to learn communication patterns in the enterprise. Using this contextual information, Sentinel can detect abnormal and malicious email attacks, removing them before they can be delivered to the user. This is very effective against attacks like phishing and business email compromise, that can be very difficult for traditional secure email gateway technologies to stop.
As well as preventing phishing attacks, Sentinel also offers domain fraud protection with a DMARC suite. Sentinel automatically generates DMARC reports within the Sentinel console. They also provide insights into email communications, with in-depth information including IPs that are passing and failing DMARC, domain misalignment and spoofing samples. Sentinel also provides DKIM/SPF configuration and troubleshooting.
Barracuda Sentinel is a good option for organizations using Office 365 who are struggling to stop phishing and account compromise attacks alongside wanting to implement DMARC. The solution is easy to deploy, and does not require any changes to your MX records. Sentinel is a popular choice for smaller and mid-sized organizations, looking for enhanced email security in the cloud.
