So what
A breach is a governance event before it is a technical one.

The leadership read

A breach is a governance event before it is a technical one. For Electrum in the sector, the hiring consequence is rarely more engineers; it is senior accountability: security, risk and data governance reporting high enough to change decisions. Across Americas, watch whether the response is a hire or a contractor; that distinction says how the board has read it.

Market context: MitchelLake's Talent Market Index sits at 109 (Hot), up 7.3 on the prior month; Americas hiring signal is running rising (+6.3pts).

Electrum: 1 signal in the last 90 days.
