Leaked credential monitoring checks whether email addresses tied to your organization appear in known data breach dumps, often available for sale or free circulation on the dark web well before most companies realize.
How to check
- Public breach-lookup services (like Have I Been Pwned) let you check individual addresses or verify a domain
- Ongoing monitoring services can alert you automatically as new breaches surface, rather than requiring manual re-checks
If credentials are found
- Force a password reset for the affected account(s) immediately
- Check whether that same password was reused anywhere else — credential stuffing relies on password reuse across sites
- Enable multi-factor authentication if it isn’t already required
FAQ
Does a leaked password mean the account was definitely compromised?
Not necessarily immediately, but it should be treated as compromised going forward — the password is now public regardless of whether it’s been actively used yet.
