Dark Web Monitoring for Business Credentials

Dark web monitoring searches criminal forums, paste sites, and dark web marketplaces for your organization's email addresses and credentials — alerting you when employee login data appears in a breach. Early detection allows credential resets before attackers use the data. Free option: Have I Been Pwned (haveibeenpwned.com) allows domain monitoring — register your domain and receive email alerts when any email address on your domain appears in a breach dataset. Microsoft 365 Defender also includes some compromised credential monitoring. Commercial options with broader coverage: SpyCloud, Digital Shadows, Recorded Future, and many MSSP-offered services. These monitor for not just email/password dumps but also internal credentials, VPN credentials, and session cookies stolen by infostealer malware. When credentials are found in a breach: immediately reset the password for that account, revoke active sessions (in Azure AD: Revoke Sessions), and check sign-in logs for any recent suspicious activity on that account. Enforce MFA if not already in place. Determine if the same password was reused elsewhere — an argument for requiring password manager use organization-wide.
