Phishing is the use of deceptive email to steal credentials, money, or data. Defense combines domain authentication, inbound filtering, user training, and rapid reporting.
Does DMARC stop all phishing?
It stops exact-domain spoofing. Lookalike domains and display-name spoofing require additional controls.
Why does phishing protection matter for deliverability?
Phishing remains the leading initial access vector in breaches. Domain owners also bear brand damage when their name is spoofed.
What is the first step to get started with phishing protection?
Enforce DMARC p=reject so exact-domain spoofing fails.
What is the most common phishing protection mistake?
Blaming users while leaving the domain unprotected.
