Ehsan's Growth Take

Here is what most CISOs get wrong about email security: they think their secure email gateway handles it. It does not. BEC attacks use no malicious links, no attachments — just persuasive text from a spoofed executive. Abnormal's behavioral model profiles how your CFO actually writes and flags when someone is pretending to be them. Deployed via API in 15 minutes, no MX changes. If BEC is your number-one risk vector (and for most companies it is), this should be your first purchase after EDR.
