In addition to a traditional secure email gateway, Barracuda relies on deep integration with Microsoft Office 365 to identify and stop threats that gateway-based solutions like Mimecast can't. This integration gives visibility directly into your Office 365 inbox, scanning internal and historical mail—giving you protection beyond your email gateway.

To protect against all email threat types organization need to deploy both email gateway and API-based inbox defense. By relying solely on Mimecast’s gateway, organizations leave themselves open to most sophisticated attacks like business email compromise and account takeover.

Mimecast uses static rules and policies—reputation analysis, block lists, and malicious payloads—to determine if an email is malicious. Socially engineered emails such as spear-phishing attacks are too complex to be stopped by policy-based security.

Barracuda goes beyond rules. Barracuda’s AI learns unique communication patterns within your organization through access to internal and historical communications. It understands what good and legitimate emails look like for each user and is able to detect signs of malicious intent within every email. This context-based detection is more effective at blocking targeted attacks, which are designed to bypass traditional rule-based email security.

Account takeover is one of the most rapidly growing email security threats, and a complete email security strategy must offer protection against it. This is where Mimecast again falls short. Protection from account takeover requires new technology that has visibility into internal email traffic.

Barracuda’s AI engine detects and blocks most sophisticated email attacks that could lead to account takeover, and identifies behavioral and content-forwarding anomalies within already compromised accounts, to help you quickly identify and remediate against account takeover in real time.

Mimecast does not offer automated incident response, leaving your organization exposed to sophisticated threats. Barracuda automates incident response and gives access to threat insights for faster and more efficient remediation. We help to identify anomalies in delivered email and proactively find attacks that bypassed email security. Our solution identifies compromised users in need of training and improves workflow for more seamless incident response.

Even with the best email security technology, it is possible for threats to reach vulnerable users. An impersonation attack could target a user via their personal email or possibly via fraudulent SMS or voicemail messages.

Barracuda offers a powerful, multi-vector phishing simulation and education platform. You can test your users’ ability to identify threats and send targeted training to your most vulnerable users. Only Barracuda ensures your users are enabled to identify all 13 email threat types, using real-world threat simulations pulled from our global threat intelligence network.
