Whisper is an AI-native internet infrastructure intelligence company. We map the relationships between IPs, domains, networks, threat lists, TOR exits, hosting and ownership into a continuously enriched graph of more than 47 billion datapoints, so security teams and AI agents understand not just what they see, but what’s behind it. Whisper Graph turns isolated indicators into connected intelligence for investigation and threat hunting. Whisper Graph XDR brings that context into detection and response, cutting off risky infrastructure at the connection. Whisper Graph MCP gives AI assistants direct access to it all. On-prem and EU-sovereign.
