Feature	Whisper
STOA Rating	7.0
Description	Whisper maps the internet's entire infrastructure — 46 billion data points covering domains, IPs, certificates, ASNs, and routing — into a single queryable graph. Security teams use it to enrich SIEM alerts automatically, trace attacker campaign infrastructure from a single domain, and map their full external attack surface. You get to it via direct API, native platform connectors, or an MCP server that lets any AI agent query the graph.
Strengths	•46 billion data points in one connected graph — covers infrastructure relationships other tools treat separately •Three integration modes (API, platform connectors, MCP) fit every team's existing workflow •Adversary infrastructure mapping that used to take days of manual pivoting now takes one query
Weaknesses	•Enterprise-only pricing with no self-serve plan — you must book a demo to evaluate •Requires security expertise to write effective Cypher graph queries •New entrant competing against established players like Censys, Shodan, and PassiveTotal
Key Features	•Query 46 billion infrastructure data points — domains, IPs, certs, ASNs — with Cypher queries over REST •Auto-enrich SIEM alerts with full infrastructure context before your analyst opens the ticket •Give AI agents direct internet intelligence via MCP — works with Claude, GPT, or any open-source model •Trace an adversary's full campaign infrastructure from a single C2 domain in seconds •Deploy cloud-hosted or on-prem depending on your security requirements
Pricing	Contact for pricing
Best For	All industries
AI Features	AI-Powered Native MCP server lets any AI agent query the full 46-billion-point infrastructure graph — ideal for agentic threat investigation workflows. Also integrates with AI-powered SIEM and SOAR platforms via native connectors.
Categories	AI Tools & AssistantsBuild & Connect
STOA Verdict	Whisper is built for SOC teams and threat intel analysts who need to see how internet infrastructure connects — not just scan individual IPs. The 46-billion-point graph and MCP integration genuinely differentiate it from isolated scanning tools. The main barrier is there's no self-serve trial — getting access requires a sales call.
