Why email is the #1 attack vector
Email remains the number-one way attackers get in. Beyond spam, the real money is in Business Email Compromise (BEC) — convincing, targeted messages that trick staff into wiring funds or handing over credentials.
The layers of defense
| Layer | Stops |
|---|---|
| SPF / DKIM / DMARC | Spoofed senders using your domain. |
| Anti-spam & AV | Bulk mail and known malware. |
| Safe Links / Safe Attachments | Malicious URLs & files — detonated in a sandbox. |
| Impersonation / BEC protection | AI spotting anomalous "CEO" or vendor requests. |
Why BEC is so dangerous
BEC often contains no malware and no bad link — just a convincing message ("please update the bank details for this invoice"). It slips past traditional filters, which is why authentication + AI anomaly detection + trained users must work together.
Set DMARC to enforce. Many organizations publish DMARC in "monitor only" and never move to enforcement — leaving the door open to domain spoofing. IDENETY tunes SPF/DKIM/DMARC to a safe enforcement policy. See our DNS records guide for details.
