Breach Disclosure & Materiality

Public companies are obligated to disclose material cybersecurity incidents on a short, unforgiving clock, and the hardest part of that obligation is not the filing. It is knowing, with evidence, that a material breach has actually occurred.

Mythic observes breaches from the attacker’s side. Because it watches adversary infrastructure rather than your endpoints, it produces empirical evidence of compromise: which of your networks are communicating with malicious command-and-control infrastructure, when the contact began, and how severe the exposure is. None of it depends on the very systems an attacker may already control.

That evidence gives disclosure teams a defensible, documented basis for materiality decisions: to disclose promptly when the facts warrant it, and to avoid over-disclosing when they don’t.
