DarkWebSonar is a web and API platform for monitoring dark-web activity, breach exposure, and threat-actor signals. It watches ransomware groups, Telegram channels, data leaks, breach repositories, and underground forums, then sends real-time alerts when an organization is mentioned. AI-filtered intelligence adds 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 on leak blogs. Exposure checks cover domains, email credentials, infostealer logs, and stolen-data leaks. Lookalike-domain monitoring identifies typosquatting and phishing or impersonation signals. Integrations include Slack, Microsoft Teams, PagerDuty, ServiceNow, custom webhooks, and an MCP server; Splunk is marked coming soon. Plans start at 49.00 USD per month, with a 14-day trial. The trial includes keyword and actor monitoring plus one-time domain breach and infostealer checks.
