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.




Phishing is an attack that sends fraudulent email communications which appear to come from a reputable source. The goal of the attack is to steal sensitive data like credit card and login information. Gartner reports that 27 percent of the data breaches in 2020 involved the theft of credentials by phishing.

Cloud Mailbox Defense focuses on specific threats, often in the realm of hard-to-detect phishing. The content of every message is analyzed to identify phishing, BEC, and spam.
