If you need account-takeover detection live today, Abnormal AI and IRONSCALES document it.",{"q":620,"a":621},"Does Microsoft Defender for Office 365 stop business email compromise?","Partly. Plan 1 adds user and domain impersonation protection with mailbox intelligence, which catches many spoofed-executive and lookalike-domain messages. Microsoft documents no dedicated vendor-email-compromise feature, so messages sent from a real but compromised supplier account are where an API layer such as Sentaro adds the most. Defender stays on underneath; Sentaro is designed to run with it.",{"q":623,"a":624},"Can BEC be detected without a link or attachment?","Yes, and it has to be, because most BEC carries neither. Detection relies on intent (a payment request, secrecy, an artificial deadline), sender signals (display-name mismatch, newly registered lookalike domain) and relationship context (a known supplier suddenly changing bank details, a reply injected into an old thread). Sentaro’s Message vector treats payload-free BEC as a core design target.",{"q":626,"a":627},"What is the difference between BEC and vendor email compromise?","Business email compromise is the umbrella term for fraud by email impersonation or account misuse. Vendor email compromise (VEC) is the variant where the attacker controls or imitates a real supplier, usually inside an existing invoice thread, to redirect a payment. VEC is harder to catch because the sender may be genuine, which is why thread and relationship history matter.",{"q":629,"a":630},"Do I need a payment-verification tool like Trustpair or Eftsure as well?","If you pay many suppliers by bank transfer, it is a sensible second control. Trustpair and Eftsure do not scan email; they verify the bank account before payment, so they stop the money even if a fraudulent email convinced someone. Email-layer BEC protection stops the request from reaching finance in the first place. The two work together.",{"q":632,"a":633},"How much does BEC protection cost?","Among the email tools here, only some publish prices: Sentaro charges $6 per protected account per month or $68 per year, with the first account free; Defender for Office 365 Plan 1 is $2 and Plan 2 $5 per user per month; Sublime Security is free to 100 mailboxes on its managed cloud.
