GreyNoise Intelligence

What GreyNoise Intelligence does

GreyNoise Intelligence is a Washington, D.C.-based cybersecurity company that operates a real-time, primary-sourced threat intelligence platform powered by its Global Observation Grid — a global fleet of 5,000+ deception sensors deployed across 80+ countries that mimics commonly exploited software and captures full-packet traffic for classification. The platform processes more than 800,000 unique IPs observed daily, classifies IP intent (benign, malicious, suspicious, unknown), tags behavior, and exposes data through a proprietary query language (GNQL), a REST API with Python SDK, a Visualizer web portal, and bulk data files. Core use cases include CVE Disclosure Early Warning, Compromised Asset Detection, SOC Efficiency / alert reduction, Incident Investigation, and Threat Hunting, organized as a platform-plus-modules architecture: the GreyNoise Platform (Standard / Advanced / Elite tiers) with nested intelligence modules (Triage, Investigate, Hunt) and add-on modules (C2 Detection, Business Services, Vulnerability Prioritization). A separate GreyNoise Block product delivers configurable, firewall-grade real-time blocklists for SMB and mid-market buyers, while Project Swarm extends the sensor network into a community-led collective defense initiative.

The company monetizes through quote-based annual subscriptions on tiered platform SKUs plus separately licensed intelligence modules, a free community tier (Vizualizer) offering up to 50 IP lookups per week as a PLG funnel, and a 14-day free trial for GreyNoise Block. Pricing is opaque ("Talk to us about pricing") with module nesting (Hunt includes Investigate includes Triage) and unlimited integrations/users bundled into every paid tier. Distribution combines enterprise field sales, self-serve PLG, channel partners (resellers, MSSPs, OEMs), and 34+ pre-built integrations with SIEM, SOAR, TIP, XDR, firewall, and AI platforms (Splunk, CrowdStrike Falcon, Google SecOps, Palo Alto XSOAR, Microsoft Sentinel / Copilot for Security, MISP, OpenCTI, Recorded Future, etc.) plus firewall External Dynamic List distribution to AWS, Azure, Cisco, Fortinet, Check Point, Zscaler, and others. The company cites 80,000+ users, 60% of the Fortune 1000, 400+ global government agencies, and 11 US Federal Agencies as customers, backed by strategic investment from In-Q-Tel (2021) and a $15M Series A led by Radian Capital (2022), with a single acquisition (Krit, 2022) used to build product design and development capacity.

Direct peers

• Recorded Future: Recorded Future operates a large-scale threat intelligence platform aggregating data across the open, dark, and deep web for SOC, vulnerability, and brand-protection use cases. It is the closest direct peer to GreyNoise in primary-sourced threat intelligence feeding enterprise SIEM/SOAR/TIP workflows.
• Shodan: Shodan is the most widely known internet-wide scanning and device-intelligence platform. It is directly comparable to GreyNoise in telemetry collection methodology (active internet scanning) and in selling exposure/intelligence to security teams, though Shodan leans more toward exposure-management than active-attack classification.
• Censys: Censys provides internet-wide scanning intelligence and attack-surface management for security teams. Like GreyNoise, it operates proprietary global scanning infrastructure to deliver primary-sourced data on hosts, services, and certificates, competing for similar enterprise use cases.
• Anomali: Anomali is a threat intelligence platform and TIP vendor that aggregates threat feeds and integrates with SIEM/SOAR — overlapping directly with GreyNoise's enrichment and SOC-triage use cases, especially via its Anomali TIP integration that already lists GreyNoise as a data source.
• BinaryEdge: BinaryEdge is a cybersecurity data company providing continuous internet scanning, exposed-asset discovery, and threat intelligence feeds. It is comparable to GreyNoise in primary-sourced telemetry collection and in serving security teams with IP/host context for triage and threat hunting.
• Onyphe: Onyphe aggregates and curates internet-scanning data (open ports, vulnerabilities, exposed assets, dark-web exposure) and sells threat intelligence feeds to security teams. It is comparable to GreyNoise in methodology and target buyer, though it positions more toward OSINT/exposure data.
• ThreatConnect: ThreatConnect offers a TIP and threat intelligence platform with built-in analytics, scoring, and SIEM/SOAR integration. It overlaps directly with GreyNoise on TIP enrichment and SOC triage workflows and lists GreyNoise as one of its enrichment data sources.
• EclecticIQ: EclecticIQ is a threat intelligence platform vendor (CTI, TIP) serving enterprise and government customers, with deep integrations into SIEM/SOAR. It is comparable to GreyNoise in target market and in ingesting/enriching IP/CVE data for analyst workflows.

Broad incumbents

• Flashpoint: Flashpoint delivers finished threat intelligence, vulnerability intelligence, and fraud data across the deep/dark web for enterprise security teams. It is comparable to GreyNoise in customer and use case (intelligence-driven defense) but is broader in scope and incumbent in market presence.
• RiskIQ (Microsoft Defender Threat Intelligence): RiskIQ, now Microsoft Defender Threat Intelligence, provides internet-scale scanning and attack-surface intelligence bundled into Microsoft's security platform. It is a broad incumbent comparable to GreyNoise in primary-sourced scanning intelligence and enterprise distribution.
