Barracuda Email Protection vs Microsoft Purview Customer Lockbox comparison

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.

Most operations, support, and troubleshooting performed by Microsoft personnel and sub-processors do not require access to customer data. In those rare circumstances where such access is required, Customer Lockbox for Microsoft Azure provides an interface for customers to review and approve or reject customer data access requests. It is used in cases where a Microsoft engineer needs to access customer data, whether in response to a customer-initiated support ticket or a problem identified by Microsoft.
