Dark web monitoring: what it is and why you need it
When a company you use gets breached, your credentials can circulate on the dark web for years. Monitoring tells you before a criminal uses them.
What ends up on the dark web
Breaches expose email addresses, passwords, phone numbers, and sometimes Social Security numbers. These get bundled and sold or dumped publicly, where anyone can buy or download them.
Why monitoring matters
You can't un-leak data, but you can react fast. If monitoring flags your email in a new breach, you can change that password, enable two-factor authentication, and watch the connected accounts before anyone exploits them.
Turn alerts into action
When you get a breach alert:
- Change the password immediately — and anywhere you reused it.
- Turn on two-factor authentication.
- Consider a credit freeze if an SSN was involved.
