NodeZero Autonomously Pentests. Guard Adds Elite Human Validation.
NodeZero runs sophisticated autonomous pentests across internal, external, and cloud environments with real exploit chaining, and the Horizon3 Attack Team does solid zero-day research. Guard pairs machine-speed AI with the top 1% of OffSec operators who approve attack plans, apply creative adversary tradecraft, and validate every finding — zero false positives, not just autonomous output.
NodeZero Chains Exploits. Guard Chains Exploits + Zero-Day Research In Your Code.
NodeZero chains known vulnerabilities brilliantly. Guard's Constantine agent hunts zero-days directly in your source code, writes working exploits, and can patch the codebase. You find what nobody else has — validated by elite humans, at machine speed.
NodeZero Delivers Autonomous Reports. Guard Delivers Continuous Offensive Security.
NodeZero is a pentesting platform. Guard is a complete offensive security operating model: agentic AI plus top 1% operators plus EDR-integrated detection gap analysis plus auto-ticketing plus autonomous retest. Offense-proven security, continuously.

Adversary DNA.
Guard is more than software. It’s AI-driven offensive security, operated by the same people who’ve breached the world’s hardest targets — and built the defenses to stop them.
Our platform is designed and managed by the top 1% of offensive security operators. Red teamers who’ve uncovered zero-days, shaped global standards, and trained the best in the industry.
Guard fuses machine speed with human expertise — to validate real risk, eliminate guesswork, and help security teams act with confidence.
Because stopping threats takes more than automation. It takes experience, insight, and a platform designed to outpace the adversary.
