How LeakTrace maps to it

An External Cybersecurity Assessment reads what a firm exposes from outside: email settings, the firm’s addresses in monitored breach databases, lookalike domains, exposed services and keys left in the firm's own website code. The Rules and Insurance Briefing that comes with it maps each finding to NYDFS Part 500, with the proof behind it, so the firm can see which obligation a finding touches. The assessment is human-verified before it is released.
