TL;DR: Dark web monitoring tells you about exposure after the fact — it can't stop a breach from happening — so its real value is in fast alerts and clear next steps, like changing a password, once something turns up.
Dark web monitoring services scan hidden marketplaces and forums for your personal information that may have surfaced after a data breach.
What to Look For
Look for a service that monitors a genuinely broad range of dark web sources and known breach dumps, sends timely alerts, and clearly explains what to do next rather than just flagging that exposure occurred. Some free tools exist for basic email checks, while paid services typically monitor more data points.
The Bottom Line
