Very good threat protection, spam filtering, and cloud backups
Considering it integrates with Azure, I would like to be able to effectively set up policies where people are by default included in certain settings. For instance, for email quarantine, I can't set up a global setting. Users must go through an induction session where I guide them in configuring quarantine alerts rather than having default settings based on group membership. This seems like an oversight since they already use Active Directory details. They should assign policies based on group membership, which configures these settings by default.

Bilal Saleem - PeerSpot reviewer
Reliability and threat intelligence make this solution competitive, but AI improvements can further enhance its effectiveness
The best features of Trend Micro Deep Discovery Email Inspector include its reliability. The second valuable feature is its built-in sandbox feature, allowing for inspection of incoming emails and attachments. The sandbox is an appliance that opens any attachment in an enclosed environment to assess its impact and potential for viruses. This protects the network from harmful threats. Trend Micro has a very large R&D team with excellent threat intel, allowing them to provide better solutions than some competitors. They understand emerging threats based on the information from their EDR. The key strengths can be summarized as reliability, a good integrated one-box solution that includes a sandbox, and their R&D capabilities and good ratings, which lead to better threat intelligence. The detailed threat intelligence provided by Trend Micro Deep Discovery Email Inspector is valuable in understanding the behavior and tactics of potential email threats.

Overview

The popularity of Microsoft 365 means criminals test and design their attacks to bypass its native security features. And that means you need additional layers of defense. With Advanced Threat Protection enabled, Barracuda uses multiple layers of detection, including signature, static, and behavioral analysis, along with CPU-emulation sandboxing to accurately detect and block zero-hour targeted attacks and ransomware.

Traditional email gateways use static rules and policies—reputation analysis, block lists, and malicious payloads—to determine if an email is malicious.

Barracuda protects your Microsoft 365 inbox against evasive threats with a powerful AI engine that learns the unique communication patterns within your organization through access to internal and historical emails. Once it understands what legitimate emails looks like for each user, it can detect anomalies that signal malicious intent. This context-based detection is more effective at blocking targeted attacks, which are designed to bypass traditional rule-based email security.
