About Xernox Security

Built by Curiosity. Hardened by Experience.

Xernox Security was founded by Pablo, a lifelong gamer turned cybersecurity engineer, with a single mission: stop modern malware before it has a chance to take control.

Pablo’s interest in cybersecurity didn’t start in a classroom or a corporate lab—it started in a video game. While playing online, he encountered a remote code execution (RCE) exploit being abused by another player in the same lobby. Within moments, his system was effectively “bricked.” That experience was a turning point. It revealed how easily poorly defended systems could be compromised—and how devastating the consequences could be.

From that moment on, Pablo became determined to understand how it happened, why it was possible, and how to prevent it from ever happening again.

Years later, that determination became Xernox Shield.

A Different Philosophy of Protection

Most security products rely heavily on kernel-mode drivers and reactive defenses. Xernox Shield was built on a different philosophy:

“Once a rootkit becomes a rootkit, it’s already too late—even with kernel drivers.”

Rather than focusing on cleaning up after a compromise, Xernox Shield is designed to prevent escalation in the first place. The goal is to detect and neutralize threats at their earliest stages—before persistence, before kernel abuse, and before irreversible damage.

If you stop the loader, the stager, or the initial payload,
there is no rootkit.

Lightweight by Design. Powerful by Nature.

Performance matters. Coming from a gaming background, Pablo understood firsthand how intrusive and resource-heavy security software can degrade system responsiveness. Xernox Shield was intentionally engineered to remain lightweight, fast, and stable—without sacrificing detection capability.

Instead of deploying heavy kernel drivers, Xernox Shield operates at the Windows NT layer, the closest level to the kernel that user-mode software can safely and reliably access.

By leveraging native NT system calls, Xernox Shield can:

• Force-terminate any process (excluding PID 0 and PID 4, which represent the Windows system itself),

• Inspect and manipulate process memory to disrupt fileless malware and in-memory attacks,

• Maintain deep visibility into system behavior without expanding kernel attack surface or introducing instability.

This approach delivers EDR-grade control without the traditional drawbacks of kernel-mode enforcement.

An EDR at Heart — Built for Everyone

Technically, Xernox Shield is an Endpoint Detection and Response (EDR) platform.
Strategically, it is marketed as an antivirus to make advanced protection accessible to everyday users—not just enterprises.

Modern malware no longer relies solely on files. It abuses memory, trusted system tools, and legitimate APIs. Xernox Shield was built specifically for this reality, combining:

• Behavioral detection,

• Memory-based analysis,

• Native process control,

• Early-stage threat interception.

This is not legacy antivirus rebranded.
It is a fundamentally modern security engine designed for today’s threat landscape.

The Future of Endpoint Protection

Xernox Shield exists because modern threats demand modern defenses.
It exists to stop malware before it becomes unstoppable.
And it exists to prove that powerful security doesn’t have to be heavy, invasive, or enterprise-only.

This is endpoint protection—reimagined.
