Business Email Compromise

A business email compromise (BEC) is an email from a legitimate-looking sender or email address that tricks the recipient into sharing something confidential or valuable. The email accounts of corporate executives or wire transfer staff are often spoofed.

Cloud Mailbox Defense leverages proven Cisco Secure Email technologies to address weaknesses in Office 365 security. It blocks advanced email threats, including BEC, ransomware, phishing, spoofing, and spam. It also provides a full graphical email conversation stack that shows the entire scope of compromised messages, including inbound, outbound, and internal user-to-user messages.


Malware is intrusive software designed to damage and destroy computers and computer systems. In 2018, Gartner reported 10.52 billion malware attacks worldwide. Examples of common malware include viruses, worms, Trojan viruses, spyware, adware, and ransomware.

Cloud Mailbox Defense auto remediates messages that contain malicious content. Because it scans and remediates internal messages as well, it can spot the lateral movement and internal malware propagation that can occur after an account takeover. With Cisco Advanced Malware Protection, it combats ransomware hidden in attachments and with Threat Grid, it defends against sandboxing.
