Barracuda Email Protection

The world′s most comprehensive email protection, made radically easy.

Featured Product

Barracuda provides your Microsoft 365 email with more effective protection against phishing, business email compromise, and account takeover.


Many organizations ask themselves if native email security in Exchange Online Protection or Microsoft Defender for Office 365 provides adequate protections to safeguard their users, data, and communications. Unfortunately, protection varies depending on each user’s license, and although Microsoft is continuously improving its email security capabilities, gaps remain. As a result, IT security professionals must determine if Microsoft’s native security meets their business requirements. We have identified seven capabilities where Microsoft security may fall short and be insufficient.


  • Impersonation Protection
  • Microsoft 365 data backup
  • Zero-day attachment sandboxing
  • Time-of-click URL sandboxing
  • Threat detection efficacy
  • Email archiving
  • Conditional Access

Secure Data, Ensure Compliance

Stay compliant and resilient even during downtime.

Ransomware, natural disasters, and simple human error can cause the loss of business-critical data at any time. Organizations need a fast way to recover and restore lost data while staying productive.

Deploy flexible and complete Microsoft 365 backup.

Microsoft does not guarantee backup and recovery of Microsoft 365 data and recommends using a third-party solution. Barracuda can help by providing fast backup and flexible restoration capabilities for your Microsoft 365 email and data.

Ensure compliance and simplify e-discovery.

Compliance is a key requirement for most organizations, and the penalties for not meeting business and governmental regulations can be severe. Retain and retrieve all email communications with email archiving while meeting compliance requirements for retention and e-discovery.
