The line between
what's real and what's noise.

The DMARC is named after two things: the demarcation point — the spot in a network where one party's job ends and another's begins — and the email standard built to authenticate what's real and reject what's spoofed. Both are about drawing a line.

Some weeks that's AI infrastructure news. Some weeks it's what a security trend actually means for the person running the network. No fixed format yet, and no promise there will be one.
