Summary

Horizon3.ai is a dominant force in Google’s AI ecosystem, capturing a commanding 67% mention rate in Gemini and 58% in AI Overviews, yet it remains dangerously invisible to power users of Claude. While the brand successfully owns the 'autonomous pentesting' category, it is currently ceding the critical cloud infrastructure and rapid threat response conversations to legacy competitors like Snyk and Nessus.

Value Proposition

NodeZero delivers 100% autonomous penetration testing that safely attacks production environments to prove what's actually exploitable—not just theoretically vulnerable—enabling teams to find, fix, and verify security issues continuously without manual testing limitations.

Overview

Horizon3.ai is a cybersecurity company that provides autonomous penetration testing through its NodeZero platform. The platform safely attacks enterprise environments to uncover exploitable vulnerabilities, helping security teams prioritize real threats and accelerate remediation without human intervention.

Mission

To turn the map around—using the attacker's perspective to help enterprises prioritize defensive efforts and stay ahead of cyber threats at machine speed.

Analysis

Key Insights

What AI visibility analysis reveals about this brand

Strength

Exceptional performance in Gemini and AI Overviews, where it consistently ranks in the top 3 for 'Automating Security Validation' and 'Autonomous Pentesting Vendors'.

Strength

High relevance among Compliance-Focused GRC Directors, achieving a 75% mention rate and signaling strong trust in regulatory-driven queries.

Strength

Clear brand authority in 'vibe check' queries across all platforms, indicating a well-defined and recognizable corporate identity in training sets.

Gap

Total absence (0% visibility) in the 'Cloud and Modern Infrastructure Security' query set, leaving a massive opening for competitors like Pentera and Snyk.

Gap

Severe underperformance in Claude (8% mention rate), a platform favored by technical architects and high-level decision-makers.

Gap

Low average positioning (10.5) for GRC personas, suggesting that while the brand is mentioned, it is rarely the primary recommendation for compliance use cases.

Opportunity

Directly challenge Pentera's lead in average positioning (2.7 vs Horizon3.ai’s 16.0 in ChatGPT) by optimizing technical documentation for OpenAI's crawler.

Opportunity

Leverage existing dominance in automated pentesting to bridge into the 'Zero-day/Log4j' rapid response conversation where Gemini is already showing early traction.

Opportunity

Capitalize on the Overwhelmed SOC Manager persona by creating workflow-specific content that mirrors the 'continuous security validation' queries currently being missed.

Recommended Actions

!

Develop and index high-authority technical whitepapers focused on 'Cloud and Modern Infrastructure Security' to address the 0% visibility gap.

Horizon3.ai is currently non-existent in cloud-related security queries, allowing competitors to claim the 'modern infra' narrative unchallenged.

Impact: High
!

Optimize technical knowledge bases and API documentation specifically for Claude’s training data and retrieval-augmented generation (RAG) processes.

An 8% mention rate in Claude represents a significant missed opportunity with technical CISOs who rely on Claude for sophisticated security reasoning.

Impact: High
~

Create 'Continuous Security Validation' (CSV) workflow guides targeting the Overwhelmed SOC Manager persona.

SOC Managers currently see a 36% mention rate; providing structured, instructional content will improve mention frequency for intent-heavy workflow queries.

Impact: Medium
~

Execute a competitive counter-positioning campaign against Pentera, focusing on ChatGPT and AI Overviews.

Pentera is the primary threat with a 2.7 average position; Horizon3.ai needs to displace them in comparison-based 'top-rated vendor' queries.

Impact: Medium
