A dark web monitoring alert is not a breach notification.
It's something more useful: advance warning.
When an alert fires, it means data tied to your business (an employee login, your email domain, customer records) has shown up on a dark web marketplace, forum, or data dump. Usually it got there through a breach at a third-party service your team uses, a phishing email, or a resale between criminal groups.
The alert doesn't confirm anyone has used that data yet. It does confirm the data is now held by people who intend to.
That's the window. The time between the alert and your response is your exposure window, and it's the only part of this you control.
We put together a plain-language guide for business owners and office managers: what each alert type means, how urgent it is, the eight steps to take, and when to call in a security professional.
