What is Data Leak Monitoring?
Breachsense tracks hacker forums, Telegram channels, ransomware leak sites, and infostealer logs. We crack hashed passwords to plaintext so you know exactly what’s exposed. You can search by email, domain, or company name and get results across all your monitored assets.
The average company takes 204 days to discover a breach. With leak monitoring, you’ll know within minutes. According to IBM’s 2025 Cost of a Data Breach Report, breaches caught early cost about $1.1 million less than those found late.

You add your domains and assets to the platform. Breachsense then scans IRC and Telegram channels, private cybercrime communities, and ransomware leak sites for matches. It monitors for employee credentials, C-level executive accounts, remote access credentials (SSH, RDP, FTP), and internal documents. When your data appears, you get an alert with details on what was exposed.
Breachsense monitors hacker forums, criminal marketplaces, Telegram channels, ransomware leak sites, paste sites, and infostealer logs. We also index leaked files from ransomware attacks so you can search for your company name or employee names in vendor breach dumps. Hashed passwords are cracked to plaintext so you know exactly what’s at risk.
Breachsense detects leaked data within minutes of it appearing on monitored sources. The average company takes 204 days to discover a breach without monitoring. According to IBM’s 2025 Cost of a Data Breach Report, breaches caught early cost about $1.1 million less than those found late. Faster detection means less time for attackers to exploit your data.
No. A data leak is an unauthorized release of confidential data, often accidental. Leaks happen through misconfigured databases, human error, or insider actions. A data breach involves deliberate unauthorized access where attackers compromise systems to steal information. Both expose your data, but the cause is different. You need monitoring for both to stay protected.
Reset the compromised passwords immediately. If session tokens were leaked, revoke them so attackers can’t bypass MFA. Check what else was exposed — internal documents, customer records, or access credentials. Notify affected parties if required. Then investigate how the leak happened. Was it a vendor breach? A misconfigured database? An employee reusing passwords? The answer tells you what to fix.
