WhisperGraph review
A security-focused graph engine for joining live infrastructure and threat data.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
WhisperGraph is a cloud and self-hosted graph engine for investigating internet infrastructure and security data. It connects DNS, addressing, routing, ownership, email posture, threat intelligence and physical network information in one graph. Security teams can run read-only Cypher queries through an HTTP endpoint, CLI, MCP access or an embeddable graph API. Typical work includes resolving hostnames, tracing routing relationships and enriching indicators, making it a focused fit for security investigations rather than broad graph application development.
The pricing structure starts with a free Community plan containing full graph data, limited AI Context via MCP and shared cloud access. Starter costs €49 per month with limited direct API access and business-hours support. Professional is €249 per month and adds full direct API access, full integrations and 24/7 support. Business is €3,000 per month with the same listed feature set, while Enterprise is a custom plan. Integrations span Splunk, Microsoft Sentinel, OpenCTI, Wazuh, n8n, MISP, SOAR and MCP, giving teams several paths into existing security workflows.
Its standout capability is the way specialized graph joins and live data computation support infrastructure analysis. Prefix indexing and address-trie CIDR containment help with network-focused queries, while live BGP, DNS and certificate data can be computed during a query. MCP and CLI access also support AI-agent and repeatable-recipe workflows. The read-only Cypher model keeps the product centered on analytics and enrichment, so teams needing graph mutation, general-purpose application storage or a broader database workload should choose another platform. WhisperGraph fits organizations from small teams to enterprises that prioritize connected security intelligence.
