H1 Platform Delivers Continuous Threat Exposure Management at AI Scale with Validated Exploitability

The H1 Platform delivers agentic AI across the full security lifecycle, paired with the world's largest community of security researchers, to close the discovery-remediation gap that defines security in the AI era.

SAN FRANCISCO--(BUSINESS WIRE)--HackerOne, a global leader in Continuous Threat Exposure Management (CTEM), today announced the H1 Platform, an agentic AI platform designed to help enterprises eliminate exploitable risk with continuous discovery, validation, prioritization, and remediation at AI scale.

The launch comes as the discovery-remediation gap becomes the defining security problem of the AI era. AI is now writing meaningful portions of enterprise code. Recent surveys indicate 73% of engineering teams now use AI coding tools daily, and AI-powered security tools are surfacing vulnerabilities faster than security teams can validate and remediate them. H1 Platform data shows vulnerability submissions up 92% year over year, with critical and high-severity findings climbing while remediation throughput lags by a wide margin.

The H1 Platform addresses this challenge by applying agentic AI capabilities throughout the CTEM lifecycle to validate and remediate exploitable vulnerabilities. Powered by Hai, HackerOne’s agentic AI orchestrator, the platform correlates exploitability signals, remediation intelligence, and observed attack trends to help organizations prioritize high-impact risk.

“In a world reshaped by frontier AI models, security can’t afford to be static, theoretical, or siloed. It must be continuous, validated, and tied to business impact,” said Nidhi Aggarwal, Chief Product Officer at HackerOne. “As exploit windows shrink and vulnerability volume accelerates, organizations need security systems that can continuously discover and validate what matters, prioritize action, and operationalize remediation at AI scale to continuously reduce cyber risk.”

"The AI era demands a new kind of security platform: agentic, continuous, and operating at the speed of the threat. The H1 Platform closes the discovery-remediation gap that defines this moment, built on the only foundation that could make it work: the simultaneous trust of the Fortune 500 and the world's largest community of security researchers, sustained over more than a decade,” said Kara Sprague, HackerOne’s Chief Executive Officer. “As enterprises move from securing code to securing AI itself, the researcher community's role on this platform will only deepen."

Central to the H1 Platform is the global community of security researchers, who bring adversarial depth that no automated system replicates. Where Hai delivers speed and scale, the global community pushes beyond what any model can reach, surfacing business logic flaws, novel attack chains, and adversarial techniques no training set contains. The result is evidence-based exploitability confirmation, not theoretical risk scores. As enterprises move from securing code to securing AI itself, the researcher community's contribution to the platform will continue to expand beyond finding individual vulnerabilities to shaping the intelligence that protects enterprises at AI scale.

How the H1 Platform Delivers Continuous Threat Exposure Management

With agentic capabilities built into the H1 Platform, it unifies discovery, validation, prioritization, and remediation into a single operational system for continuous exposure management. Key platform capabilities include:

• Continuous agentic testing across the attack surface, with exploitability validation informed by program history and attack-path analysis
• Agentic prioritization that ranks vulnerabilities based on exploitability and business impact
• Integrated remediation workflows across Jira, GitHub, ServiceNow, Azure DevOps, Linear, and dozens of other enterprise integrations
• Agentic exploitation workflows that generate validated, evidence-backed findings routed directly to developers for immediate remediation
• Board and CISO-level executive analytics, including Return on Mitigation (RoM) metrics, designed to help organizations quantify exposure reduction, prioritize remediation investments, and concretely measure security outcomes

Measured Outcomes

The H1 Platform supports 1,300 organizations worldwide, including 20% of the Fortune 500 and leading AI innovators, helping security teams continuously validate and remediate exploitable risk at scale. Across its customer base, HackerOne has helped organizations mitigate more than $32 billion in exposure risk and reduce mean time to remediate (MTTR) by approximately 80%.

"We went from a set-and-forget security program to one that actually keeps pace with how fast threats move,” said Scott Brown, Security Lead, KOHO Financial. “Reducing median triage time by roughly 80% has changed everything. Our team focuses on what's confirmed and exploitable, and vulnerabilities get addressed before they become real risk."
