What is dark web?
The dark web is a part of the internet that isn't indexed by search engines and is only reachable with special software like Tor. While it has legitimate privacy uses, it's also where stolen credentials, breached data and attack tools are bought and sold.
Why the dark web matters for security
When your organization's data leaks — passwords, customer records, internal documents — it often surfaces on dark web forums and marketplaces. Attackers buy it to fuel credential stuffing, account takeover and targeted phishing.
You can't police the dark web, but you can watch it: monitoring for your exposed credentials turns a hidden leak into an early warning.
Dark web vs. deep web
The 'deep web' is simply everything not indexed by search engines — like your email inbox or banking portal — and is mostly mundane. The 'dark web' is a small, deliberately hidden subset often associated with anonymity and illicit trade.
How to prevent dark web
- Monitor the dark web for your exposed credentials and data.
- Force password resets when credentials appear in a leak.
- Enforce MFA so leaked passwords are less useful.
- Reduce phishing and breaches that put data there in the first place.
