AI HACKER-BASED PENTEST SERVICEAn AI hacker automatically checks a vast range of assets, and
ethical hackers validate it with precision

AI automatically explores large-scale assets around the clock, and ethical hackers validate the findings firsthand to deliver results free of false positives.

Attackers are already armed with AI

Conventional penetration testing relied on specific tools and ethical hackers manually checking a fixed scope. Attackers, however, use AI to automatically explore the entire asset base—including what defenders overlook—around the clock. Right now, enterprises, financial institutions, and public agencies holding large-scale information assets are exposed to serious risk.

  • 2,383 cases

    Reported security breaches in Korea in 2025

    Up 26.3% year over year

  • 90%

  • AI-Automated Attacks

    Combining automated vulnerability detection with privilege takeover,

    compound attacks have become a reality

It's time defenders responded with AI of their own. The AI hacker AlienRay moves first, and senior ethical hacking experts validate the results with precision.

    Report Delivery

    Final report delivered, including risk levels, reproduction steps, and remediation recommendations

AlienRay — AI-Based Vulnerability Analysis Solution

AlienRay is an AI-based vulnerability analysis solution developed in-house by STEALIEN. Specialized AI engines for each area analyze assets from an attacker's perspective, combining automated exploration with expert validation to go beyond the limits of conventional penetration testing.

*AlienRay runs on Diffuto, an AI-based vulnerability analysis engine.

Proven technology—AI moves first

Here's why AlienRay, built on STEALIEN's own technology, is different from conventional penetration testing.

  • AI Automation — Assessment Without Scope Limits

    AI overcomes the time and scope limits of manual assessment. It explores large-scale assets around the clock and runs attack simulations.

  • Human in the Loop — Precise Expert Validation

    Senior ethical hackers validate the results AI collects firsthand. We minimize false positives and accurately assess real risk levels.

  • Proprietary Technology Diffuto — The Core Engine of AI Vulnerability Analysis

    AlienRay runs on Diffuto, the AI vulnerability analysis engine STEALIEN developed in-house. It embodies proprietary technical capabilities found nowhere else among solutions.

  • Integrated Coverage Across 6 Areas

    Attack surface management, web, mobile, Windows, IoT, and source code—all assessed within a single integrated service.

Conventional Penetration Testing vs AlienRay

Conventional

  • Human-centered manual assessment → limited time and scope
  • One-off project approach

AlienRay

  • Continuous assessment of large-scale assets through AI automation
