Company profile
researched Aug 2026RiskIQ, Inc. was a cyber security company headquartered in San Francisco, California, founded in 2009. It provided cloud-based software as a service used by organizations to detect phishing, fraud, malware and other online security threats, and it monitored advertising networks for malvertising and spyware while also offering mobile application security services.
The company's platform centered on digital attack surface management: discovery, intelligence and mitigation of threats associated with an organization's digital presence across the Microsoft cloud, AWS, other clouds, on-premises environments and supply chains. It combined internet data reconnaissance and analytics to help security analysts, security teams and CISOs expedite investigations, assess risk and remediate exposed internet-facing assets. RiskIQ also delivered global threat intelligence collected across the internet, crowd-sourced through its PassiveTotal community of security researchers and analyzed with machine learning, giving customers context on attack sources, attacker tooling and indicators of compromise. Customers used these capabilities within vulnerability management, application security and penetration testing programs. RiskIQ was a member of the Cloud Security Alliance.
Founding story
RiskIQ was co-founded in 2009 by Elias "Lou" Manousos, Chris Kiernan and David Pon, with Manousos serving as CEO.
Business model
RiskIQ sold cloud-based software as a service to enterprises, providing attack surface management and threat intelligence subscriptions used by security teams.
Traction
As of 2020, over 6,000 organizations worldwide used RiskIQ's capabilities for cybersecurity programs including vulnerability management, application security and penetration testing. Named customers include Standard Bank, which deployed RiskIQ's suite in May 2018.
Latest developments

Market position
RiskIQ was described by Microsoft as a leader in global threat intelligence and attack surface management. It reported use by eight of the ten largest U.S. financial institutions and five of the nine leading internet companies worldwide, and by more than 6,000 organizations globally.
RiskIQ combined externally sourced internet reconnaissance data with a crowd-sourced researcher community (PassiveTotal) to map an organization's full internet-facing attack surface across multiple clouds, on-premises systems and supply chain, rather than focusing only on internal telemetry.
Technology
The products were powered by proprietary virtual-user technology, a threat analysis engine and a global proxy network, with more than a decade of internet scanning and analysis. Threat intelligence was crowd-sourced through the PassiveTotal community of security researchers and analyzed using machine learning, enabling security teams to graph connections between their digital attack surface and attacker infrastructure and activity.
Go-to-market
Large enterprises and their security analysts, security teams and CISOs, including financial institutions, internet companies and, following the 2020 Series D, critical infrastructure industries.
Geography
Headquartered in San Francisco, California, with customers worldwide including financial institutions in the U.S. and Standard Bank in South Africa.
History
Founded in 2009 in San Francisco, RiskIQ raised $10 million in Series A funding from Summit Partners in February 2013 and $25 million in Series B funding led by Battery Ventures in May 2014, with MassMutual Ventures first investing in the 2014 Series B. In June 2020 it raised a $15 million Series D led by National Grid Partners. In May 2018 Standard Bank deployed RiskIQ software to automate threat analysis of brand infringement, cybercrime and web-based attacks against its digital presence.
