Learn MoreFrequently Asked Questions
Data breach monitoring is the continuous process of scanning dark web marketplaces, hacker forums, and criminal channels for your organization’s compromised data. It alerts security teams the moment employee credentials, customer information, or sensitive company data appears in a breach. This lets you reset passwords, terminate sessions, and prevent account takeover before attackers exploit the leaked data. Organizations typically use data breach detection tools to automate monitoring across thousands of sources.
We continuously track millions of dark web sources including IRC and Telegram channels, private cybercrime forums, and ransomware leak sites. You’ll get instant alerts the moment we detect your:
- Employee or customer credentials * C-level executive account access * Remote access credentials (SSH, RDP, FTP) * Internal emails or confidential documents * Corporate or government-issued employee IDs This lets you reset passwords and lock down compromised accounts before attackers exploit them.
Real-time breach detection lets you respond within minutes instead of weeks or months. The moment we detect compromised data, you can:
- Reset passwords before account takeover occurs * Terminate active sessions to block unauthorized access * Prevent fraudulent purchases with stolen payment data * Upgrade security controls to address specific vulnerabilities This speed reduces breach costs by an average of $1.9 million compared to delayed detection.
No, they’re different. A data breach involves malicious unauthorized access where attackers compromise a system to steal data. A data leak is accidental exposure of data, often from misconfigurations, human error, or insider threats. Both require monitoring, but breaches typically involve external threat actors while leaks can happen without malicious intent. You need to monitor for both to protect your organization’s sensitive information.
Breachsense allows you to search across multiple data breaches, infostealer logs, and combo lists to see if your data has been breached. Use the Breachsense dark web scanner to see which of your organization’s accounts have been compromised.
Detecting a data breach requires continuous monitoring across a broad range of sources, like the dark web, hacker forums, and ransomware channels, for compromised data. By tracking leaked credentials, stolen company data, and patterns of unusual activity, organizations can identify breaches early. Following CISA’s breach prevention guidance alongside continuous monitoring provides a comprehensive defense strategy.
According to IBM’s 2025 Cost of Data Breach Report, the global average cost reached $4.4 million in 2025. Organizations with extensive AI-driven security operations saved $1.9 million compared to those without. Real-time data breach monitoring reduces detection time from months to minutes, significantly lowering breach costs across incident response, legal fees, regulatory fines, and lost business.
