Gartner Research Confirms Default Email Security Is Insufficient to Combat Business Email Compromise (BEC)
- by Brittany Day
Business email compromise (BEC) is a simple yet lethal attack that can have devastating effects on any business. BEC has become a favorite among cybercriminals, as these scams are simple and effective. By spoofing a trusted user, BEC requires no malware or malicious URL to convince a recipient to share valuable information or transfer significant amounts of money into the hands of the attacker.
Gartner’s research confirms that traditional methods of securing email like built-in Microsoft 365 and Google Workspace email protection are significantly limited in their ability to detect BEC attacks because of their fundamental architecture. This article will explore why BEC attacks are so prevalent and dangerous, why default email security is not enough to protect your business from this growing threat, and the type of protection that is required to defend against BEC.
BEC: An Easy Way to Inflict Major Damage
Business email compromise attacks are a growing threat to all organizations, and are very difficult to protect against. Research done by Gartner has found that BECs have increased by nearly 100% over the past three years and experts predict the attacks will continue to double yearly. Statistics collected by the FBI’s IC3 (Internet Crime Complaint Center) reveal that there were over $43 billion in losses due to BEC between June 2016 and December 2021.
The increase in popularity stems from the simplicity in execution. Attackers don’t require malware or malicious URLs to manipulate a victim into sharing sensitive information or sending large sums of money, only needing to spoof a trusted user.
Default Email Security Is Not Enough to Repel BEC Attacks
Built-in Microsoft 365 and Google Workspace email protection are insufficient to stop BEC attacks, as Microsoft 365 and Google Workspace infrastructure cannot perform the per-customer contextual analysis required for the detection of most BEC attacks. Microsoft and Google have far too many companies and customers to properly monitor all accounts and understand relationships, reputation patterns and conversation-style anomalies to detect account takeovers (ATOs) and BEC attacks. In addition, Microsoft and Google’s default protection takes a static, retrospective approach to identifying potential threats, failing to safeguard against human error, which plays a critical role in successful BEC attacks.
Gartner has noted: “...due to the rise in business email compromises, account takeovers and other sophisticated attacks, many times some malicious emails are actually missed by Microsoft Defender for Microsoft 365 (MSDO)... …Therefore, organizations should strongly consider integrating third-party solutions to strengthen their email security capabilities.”

BEC is on the rise due to it being an easy way for cybercriminals to inflict major damage and steal large sums of money from victims. As organizations move to the cloud, attackers have followed suit.
