What is Dark Web Monitoring?

Dark web monitoring scans criminal marketplaces and ransomware leak sites for your organization’s compromised data. With billions of credentials available on the dark web, continuous monitoring is essential for preventing breaches before they happen.

What We Monitor:

Compromised Credentials: Leaked usernames and passwords from data breaches and combo lists
Session Tokens: Active authentication tokens that bypass Multi-Factor Authentication (MFA)
Infected Devices: Infostealer malware infections exposing corporate data through infostealer channels
Third-Party Breaches: Vendor breaches affecting your data through supply chain compromises
Threat Actor Chatter: Discussions on dark web forums about your organization

Why It Matters:

Dark web monitoring acts as an early warning system against cyber attacks, helping you prevent them before they happen.

Yes. Dark web monitoring is worth it for any organization handling sensitive data. According to IBM’s 2025 Cost of Data Breach Report, the average breach costs $4.44 million and takes 241 days to identify and contain. Early detection through dark web monitoring is far less expensive than breach response.

Every day cybercriminals trade stolen credentials and sensitive data on dark web marketplaces. This puts organizations at risk of financial loss. Dark web monitoring services help detect exposed data early so you can respond quickly with password resets. It adds a critical layer of security by alerting security teams before credentials are exploited.

Yes, Dark Web Monitoring is safe when provided by reputable cybersecurity companies. These services use legal methods to search for stolen data on the dark web without exposing your personal information. They monitor criminal forums and criminal marketplaces where criminals trade stolen data. The process is passive, meaning your data is not actively shared or uploaded during monitoring. Reputable providers follow strict privacy and security standards, ensuring your sensitive information stays protected. Dark Web Monitoring helps you stay informed and secure your assets before they’re exploited.

Dark Web monitoring involves scanning hidden parts of the internet where cybercriminals trade stolen data. These areas are not indexed by standard search engines and require special tools to access. A Dark Web monitoring service continuously searches underground forums and marketplaces for compromised information. The most common types of data leaked include login credentials and financial records. When exposed data is found, the service alerts users so they can take action before criminals exploit it.

A dark web scan searches criminal marketplaces and breach databases for your organization’s exposed data. Unlike continuous monitoring, a scan generates a one-time dark web report of leaked credentials.

For ongoing protection, dark web monitoring services provide 24/7 surveillance with real-time alerts. A scan shows what’s already leaked. Continuous monitoring catches new exposures as they happen. Most organizations use both: an initial scan to assess exposure, followed by continuous monitoring.

Dark web monitoring works in 4 steps:

1. Continuous Scanning: Monitor dark web marketplaces and leak sites 24/7 for compromised data
2. Data Detection: Identify credentials and sensitive data related to your organization using specialized crawlers
3. Real-Time Alerts: Get notified immediately when your data appears on the dark web
4. Immediate Response: Reset passwords and terminate sessions before exploitation

Dark web monitoring continuously scans hidden websites and marketplaces where attackers trade stolen information. Specialized tools search for leaked credentials and session tokens. When matching data is found, the service sends an alert to your security team for immediate action.
