What DarkWebSonar is
DarkWebSonar is a paid web and API service for monitoring dark-web activity, breach exposure, and threat signals. It watches ransomware groups, Telegram channels, data leaks, breach repositories, and underground forums, and says it sends real-time alerts when an organization is mentioned. Its AI-filtered intelligence includes contextual risk scores based on threat actor reputation and data sensitivity. Coverage includes DDoS campaigns, defacements, early attack chatter, ransomware victim announcements, and pre-extortion warnings. Exposure checks cover domains, email credentials, stealer logs, and stolen-data leaks; lookalike-domain monitoring detects typosquatting and phishing or impersonation signals. Integrations listed as available include Slack, Microsoft Teams, PagerDuty, ServiceNow, custom webhooks, and an MCP server; Splunk is marked coming soon. Plans start at $49 a month, and a 14-day trial is available. The trial includes keyword and actor monitoring and a one-time domain breach and infostealer check; passwords stay masked, and continuous domain monitoring starts on Growth.
