What 4iQ does

4iQ, now operating as Constella Intelligence, is a cyber intelligence company specializing in identity risk intelligence built on curated breach and infostealer data. Founded in 2016 and headquartered in Los Altos, California, the company ingests, cleans, verifies, and enriches data from surface, deep, and dark web sources to deliver what it calls a Verified Identity Pedigree across 54.6 billion records and 1T+ attributes spanning 125+ countries and 50+ languages. Its core technology detects compromised credentials, stolen session cookies, brand impersonations, executive exposures, and pre-ransomware signals derived from infostealer malware analysis.

Constella sells through a dual-platform model. The 'Build' path is the Intelligence Data API, a high-speed developer endpoint that supplies identity risk data to product owners, MDR/XDR platforms, and fraud teams for embedding into detection stacks and consumer security products. The 'Investigate' path is Hunter+ DRP (Digital Risk Protection), a SOC-facing subscription platform with three modules — Executive Protection, Brand Protection, and Threat Investigation — targeted at security teams and CISOs. Both paths are delivered as quote-based enterprise subscriptions on annual contracts.

The company serves financial services organizations, telecom providers (including Telefonica), public sector and law enforcement agencies, retail/e-commerce platforms, and consumer identity protection brands (including Proton, Tadaweb, Iris Identity Protection, and Enfortra). It has raised $62M across three funding rounds (2016 Series A, 2018 Series B, 2020 Series C) from Forgepoint Capital, C5 Capital, Benhamou Global Ventures, Adara Ventures, Telefónica Innovation Ventures, Wayra Chile, and Armat Group. Go-to-market combines enterprise field sales (Hunter+ DRP), self-serve developer access (API), content-driven demand generation (quarterly/annual breach reports, webinars, blog), and a partner/reseller program.

Core offering

4iQ (operating as Constella Intelligence) sells a verified Identity Risk Intelligence platform built on a curated database of over 1 trillion attributes and 54.6 billion records covering surface, deep, and dark web sources. It offers two main commercial offerings: the Identity Data API for developers, MDR/XDR platforms, and fraud teams to embed compromised credential and infostealer data into their products, and the Hunter+ Digital Risk Protection platform with Executive Protection, Brand Protection, and Threat Investigation modules for enterprise security teams and OSINT analysts.

Product overview

Constella is a dual-platform solution comprising two distinct product paths: (1) the Build path centered on the Intelligence API, which provides high-speed access to compromised identity data for developers and MDR/XDR platforms to embed into their products, and (2) the Investigate path built around Hunter+ DRP (Digital Risk Protection), a SOC-facing platform offering Executive Protection, Brand Protection, and Threat Investigation modules. Both paths draw from the same verified data foundation—a curated identity database of over one trillion attributes across 125+ countries. The platform also includes a Data Methodology component that establishes a Verified Identity Pedigree for all records.

Direct peers

• Recorded Future: One of the largest independent threat intelligence platforms, offering breach data, dark web monitoring, and identity risk feeds that directly overlap Constella's Intelligence API and Hunter+ DRP offerings for security teams and fraud teams.
• SpyCloud: Specialist in recaptured stolen credentials, session cookies, and infostealer logs, selling identity exposure data and ATO prevention APIs to enterprises and security vendors — closely aligned with Constella's Build path and infostealer focus.
• Flashpoint: Combines finished threat intelligence with DRP capabilities across surface, deep, and dark web sources for security, fraud, and national security teams, competing head-to-head with Hunter+ DRP and Constella's OSINT modules.
• ZeroFox: External threat intelligence and digital risk protection platform with brand protection, executive protection, and takedown services — directly comparable to Constella's Hunter+ modules for enterprise security teams.
• IntSights (Rapid7): External threat intelligence platform (acquired by Rapid7) that surfaces dark web and surface web threats for security operations teams, overlapping with Constella's Hunter+ DRP for SOC and CISO buyers.
• Digital Shadows (ReliaQuest): Digital Risk Protection service (now part of ReliaQuest) focused on credential exposure, data leakage, and brand protection — overlapping Constella's Investigate path and serving the same CISO buyer.

Broad incumbents

• RiskIQ (Microsoft): Attack surface and digital risk protection platform now integrated into Microsoft Defender; competes indirectly by bundling external threat intelligence into a much broader enterprise security portfolio.
• CrowdStrike: Endpoint security leader whose Falcon Intelligence and Falcon Surface modules bundle external threat intelligence and DRP features, competing with Constella for enterprise security budget but as part of a much larger platform.
• Mandiant (Google Cloud): Threat intelligence and incident response powerhouse (now under Google Cloud) offering finished intelligence and OSINT services that overlap with Constella's Hunter+ Threat Investigation module for government and enterprise buyers.
• Kroll: Cyber risk and identity protection services firm with dark web monitoring and managed identity protection offerings, broadly comparable to Constella's Identity Theft Monitoring and law enforcement-adjacent use cases.
