Core Product Capabilities

The following capabilities are described on breachsense.com:

  • Real-Time Dark Web Monitoring Continuous monitoring of dark web marketplaces, hacker forums, ransomware leak sites, paste sites, and infostealer channels to identify exposed data.
  • Compromised Credential Monitoring Automated detection of leaked employee, customer, and vendor credentials across stealer logs, combo lists, and third-party breaches.
  • Infostealer Malware Intelligence Monitoring of stealer logs for employee devices infected with credential-stealing malware (RedLine, Vidar, Raccoon, LummaC2, and others). Detects stolen session tokens and saved passwords.
  • Ransomware Gang Monitoring Tracking of ransomware leak sites and private channels for victim data publication across 100+ ransomware groups.
  • External Attack Surface Management (EASM) Discovery and monitoring of internet-facing assets, including subdomain mapping, phishing domain detection (homoglyph, typosquatting, alternative TLDs), and certificate transparency log monitoring.
  • Full-Text Search on Leaked Files Searchable index of files from ransomware attacks, allowing search by any string to find organizational data in leaked documents.
  • Third-Party and Vendor Breach Monitoring Monitoring of vendor and supplier breaches for data related to your organization.
  • OSINT Monitoring Tracking of hacker forums, Telegram channels, criminal marketplaces, and paste sites for mentions of your organization.
  • Phishing Domain Detection and Takedown Services Detection of lookalike domains impersonating your brand, with takedown services for malicious domains.
  • Password Cracking and Data Enrichment Hashed passwords cracked to plaintext. Data enriched with context and searchable by email, domain, IP address, or hardware ID.
  • Automated Alerts Webhook and email notifications when compromised data related to monitored assets is detected.
  • API-First Access Breachsense provides a publicly documented RESTful API that allows programmatic access to all platform features.
  • Public Breach Listings The website publishes a public list of recent breaches with contextual information.
  • Free Dark Web Scan A free dark web exposure check tool is available at breachsense.com/dark-web-scan.
