What Is the Dark Web?
The dark web is a part of the internet not indexed by standard search engines and accessible only through specialized browsers. It hosts a significant underground economy where stolen credentials, leaked business data, customer records, and access to compromised systems are bought and sold, often within hours of a breach occurring.
When employee login credentials or sensitive business data surface on criminal forums or underground marketplaces, most businesses have no way of knowing. By the time a breach is discovered through other means, that data may have already been sold and used multiple times.
Why Monitoring Matters
Stolen credentials are one of the most common starting points for cyberattacks. Once a username and password appear on a criminal marketplace, attackers can use them to log into email accounts, VPNs, cloud platforms, and business applications, often bypassing security controls entirely because the login looks legitimate.
Dark web monitoring gives you early warning. When your business domain, employee credentials, or sensitive data surfaces in underground forums or breach databases, STACK alerts you so you can act before an attacker does: reset credentials, enforce MFA, investigate affected accounts, and limit the damage.

What Gets Monitored
Dark web monitoring continuously scans criminal forums, underground marketplaces, paste sites, stealer malware logs, and private Telegram channels for data tied to your business. Coverage goes well beyond a one-time scan of public breach databases.
Passwords
Employee credentials for email, VPNs, cloud platforms, and critical business applications.
Credentials
Identification documents, certifications, and account access tied to your business domain.
Intellectual Property
Proprietary data, trade secrets, internal documents, and source code that may have been exfiltrated.
Customer Data
Names, email addresses, payment details, and other sensitive customer records tied to your business.
Financial Data
Bank account details, credit card numbers, and financial records linked to your business or employees.
Continuous, Not Periodic
A one-time scan tells you about past exposure. It says nothing about what surfaces tomorrow. Stolen credentials and leaked data appear on criminal markets daily, and attackers move quickly once data is available. A monthly or quarterly scan catches exposure weeks after it's already been exploited.
STACK's dark web monitoring runs continuously, scanning underground sources around the clock. When data tied to your business domain appears, you're alerted promptly with the context needed to respond: what was found, where it appeared, and what to do about it.
When Something Is Found
An alert is only useful if you know what to do with it. When STACK identifies exposed data tied to your business, we don't just send a notification and move on. We provide context on what was found and work with your team on the appropriate response.
Immediate Alert
You're notified as soon as exposed data tied to your domain is identified, with details on what was found and where.
Credential Reset
Affected passwords are reset and impacted accounts are secured before attackers can exploit the exposed credentials.
Account Review
Affected accounts are reviewed for signs of unauthorized access or suspicious activity that may have already occurred.
MFA Enforcement
Where MFA isn't already in place on affected accounts, it's enforced to prevent future credential-based attacks.
Find Out If Your Data Is Already Out There
Most businesses don't know what's circulating on the dark web until it's too late. A Security Risk Assessment gives you a baseline picture of your current exposure, including whether credentials tied to your business domain have already appeared in known breach databases.
