How they differ

CISO Tribune files both HackerOne and Seemplicity under Exposure prioritisation and CTEM as the primary category, and HackerOne is also filed under bug bounty, penetration testing and vulnerability management. HackerOne sells the H1 Platform, which it describes as discovering, validating, prioritizing and remediating exploitable risk across the attack surface, with an agentic orchestrator called Hai. Its lineup also includes H1 Bounty, where a global community of researchers continues to do the finding, plus H1 Code and H1 Code Security Audit. Seemplicity sells the Seemplicity Platform, which normalizes and dedupes findings from more than 190 direct connections, prioritizes them, maps each asset to its owner and tracks SLAs. It also sells AI Exposure Management (AEM) and AI Exposure Response (AER), which use autonomous AI agents, and an assistant called Seema.

The offerings overlap in exposure prioritization and remediation workflow, but HackerOne also sells testing services, including AI red teaming that it says can be mapped to NIST AI RMF, SOC 2, ISO 42001, HITRUST, and GDPR frameworks. Seemplicity describes its work as consolidating findings from code, cloud and infrastructure tools and routing them to owners. HackerOne says it has tested 1,700+ AI assets across customer scopes and names frontier labs and global enterprises as organizations it serves with AI security testing. Seemplicity names Carlsberg Group as a customer using it for vulnerability management and remediation processes. On funding, Seemplicity launched with a $26 million Series A round and later raised a $50 million Series B round led by Sienna Venture Capital.

Recently, HackerOne launched H1 Remediation on July 29, 2026, and announced the H1 Platform on June 2, 2026. Seemplicity launched AI Analysts, an autonomous vulnerability triage solution, on June 24, 2026.

About HackerOne

HackerOne puts Continuous Threat Exposure Management (CTEM) in practice through a continuous loop of discovery, validation, prioritization and remediation. The H1 Platform continuously discovers, validates, prioritizes and remediates exploitable risk across the entire attack surface. The H1 Platform operationalizes CTEM as a single connected system, with Hai as the agentic orchestration layer across every stage. Each product is an entry point into the full H1 Platform.[1][2]

Hai is HackerOne's agentic AI orchestrator, powering automation across the H1 Platform. Hai coordinates agents across every stage of the platform as a single connected system. Hai scores every incoming finding and surfaces what is actually exploitable in the customer's environment. Within H1 Bounty, Hai supports a team with triage, report summaries, and remediation guidance. HackerOne's global community of researchers continues to do the finding.[2][3]

Remediation guidance routes each finding to the right owner with full exploit context, delivered into the tools a team already uses. Retests confirm that fixes hold, and regression monitoring catches recurrences before they reopen. Core capabilities include continuous asset discovery and exposure scoring, workflow automation, and 36+ integrations. Cross-program dashboards track exposure velocity, remediation speed, and signal quality. Return on Mitigation is self-serve and gives a measure of avoided financial loss. The H1 Platform's multi-model harness broadens coverage, validates outputs, and traces findings to root cause.[2]

HackerOne's product lineup covers several kinds of testing. Always-on agentic testing continuously finds, validates and proves exploitable vulnerabilities across applications. Source code-informed fix plans are delivered in one click to engineering. AI code security reviews pull requests, validates exploitability and delivers context-aware fixes into developer workflows. Incentivized, time-boxed testing focuses researchers on a specific scope or objective. H1 Code, H1 Code Security Audit, and H1 Remediation are available with opt-in frontier cyber model access, adding deeper reasoning across the codebase.[2][4]

HackerOne combines human-led offensive testing with agentic adversarial validation for AI security. HackerOne tests models, retrieval pipelines, tools, APIs, and agent workflows to validate where systems can be exploited under real adversarial pressure. AI red teaming is adversarial testing built for AI systems, models, agents, and their integrations. H1 AI Red Teaming engagements include agent-driven testing to validate prompt injection exploitability across retrieval pipelines, tool permissions, and agent workflows. Validated findings and reproducible attack traces are delivered in the HackerOne Platform. AI red teaming reports can be mapped to NIST AI RMF, SOC 2, ISO 42001, HITRUST, and GDPR frameworks. HackerOne has tested 1,700+ AI assets across customer scopes.[3][4][5]

Anthropic CISO Jason Clinton chose HackerOne's full-stack red teaming to uncover hidden risks across AI models, applications, and system integrations. HackerOne names frontier labs and global enterprises as organizations it serves with AI security testing.[2][3][5]
