Business Email Compromise in Microsoft 365

Take swift action to contain and recover from email attacks.

Email drives modern business communication, but the rising threat of business email compromise (BEC) by cybercriminals jeopardizes data security and integrity.

In today's digital age, collaborative environments have become the lifeblood of business communication, and Microsoft 365 (M365) is at the forefront of this transformation. However, this digital transformation comes with a growing threat - BEC. Cybercriminals and threat actors are constantly looking for ways to compromise sensitive information, commit fraud, and steal valuable data.

TrustedSec’s BEC offering provides a low-cost way for companies to quickly determine what actions attackers took within their M365 environment after they were compromised. Analysis will include examining M365 user activities for:

  • Attacker Sign-Ins
  • Evidence of files accessed or downloaded
  • Emails sent by attackers
  • Unauthorized MFA devices
  • Malicious mailbox rules

Additionally, TrustedSec searches the M365 tenant for other users that may have been compromised so the organization can be assured if their compromise has been contained.

BECs require swift action by organizations to contain and recover from an attack. TrustedSec’s BEC analysis lets every organization quickly respond to the attack, determine what actions were taken by attackers, and be confident that the compromise is resolved.

“TrustedSec allows me to help make an impact on our clients and help those in need.”
