RiskIQ

RiskIQ

RiskIQ was a private cybersecurity company based in San Francisco, acquired by Microsoft in 2021 for an undisclosed sum. Its technology now powers Microsoft Defender Threat Intelligence, a platform that indexes and analyzes the internet's public assets to profile cyber adversaries and their tools. No founding year or original wealth origin is publicly disclosed by Microsoft or RiskIQ's former website. The platform provides a complete map of the internet, enabling security teams to identify exposures and accelerate detection and remediation. It integrates with Microsoft Defender XDR, Microsoft Sentinel, and Microsoft Security Copilot. The tool covers cyber threat detection across multiple vectors, including IP addresses, domains, and other known entities. No named portfolio companies or external co-investors are disclosed. Microsoft has not disclosed the number of RiskIQ employees or professionals post-acquisition. The team has been integrated into Microsoft's security division. The product continues to receive updates and is marketed as a core component of Microsoft's threat intelligence suite. No further investment vehicles or affiliated entities have been identified. RiskIQ's structural differentiator is its integration into a major technology platform — Microsoft. Unlike a standalone cybersecurity firm or family office, RiskIQ now functions as a product line within a global cloud vendor, leveraging Microsoft's distribution, research, and customer base to scale its internet intelligence capabilities. No other governance or succession details are available.
