Advanced Kernel Threat Detection & Blue-Team Enablement

We help security vendors detect and defend against real kernel-level threats through private adversarial testing and advanced detection research.

What we do

We help security vendors and blue teams detect kernel-level threats through research, controlled testing, and advanced detection engineering. Our work focuses on realistic adversarial simulations, rootkit detection research, and defensive kernel security engineering.
Everything we deliver is reproducible, evidence-driven, and designed to help defenders strengthen their products and capabilities.

  • Kernel research. Loadable modules, stealth/detection studies, forensics evasion vs. countermeasures.

  • Compiler security. Obfuscation and hardening passes; analysis that exposes optimization-stage blind spots.

  • Tooling. Scripts, debuggers, and test harnesses that make experiments repeatable.

  • Trainings & knowledge transfer. Hands-on, lab-first workshops with ready-to-run QEMU images and reproducible labs; teams leave with working setups, checklists, and code.

Why Hands-On Adversarial Testing

  • Real Threats, Not Simulations

  • Detect What Attackers Actually Do

  • Validate Assumptions Before Attackers Do

  • Build Stronger Detection Engines

  • Safe, Controlled, Defensive

Security Research Services

We specialize in enhancing security for Linux kernels and compilers through innovative projects.

Kernel Module Security

Our loadable kernel module demonstrates real-world kernel-level threat techniques, enabling security teams to build stronger, proactive defenses. We also provide guidance and test scenarios to help defensive software accurately detect these behaviors.

Compiler Passes & Security

We provide a collection of compiler passes and tools aimed at identifying vulnerabilities in x86, ARM, and RISC-V binaries.

We deliver comprehensive, hands-on training in Linux Kernel Threats & Defenses.

The screen shows a text editor with various files and folders listed on the left-hand side, while the main coding area is open with a command line interface. There are green text outputs typical of command line operations performed on a black background.

Text written on a computer screen displays programming code with comments. The code uses C syntax, featuring the use of 'typedef' to define character constants. Some text appears in green, suggesting it is a comment, while other code is in blue and white, indicating keywords and standard text respectively.
