Security

Security Overview

How Meridian protects your software with defense-in-depth — from loader to runtime.

🔒

Ed25519 Signing

Every payload is signed with Ed25519. The loader verifies the signature in-memory before execution — no unsigned code ever runs.

🛡

Themida Wrapping

Payloads are wrapped with Themida for anti-tamper, anti-debug, and virtualization — raising the bar against reverse engineering.

📡

Hardware Fingerprinting

Licenses bind to TPM, disk serial, BIOS UUID, and MAC — making credential sharing ineffective.

Direct Syscalls

The loader invokes kernel services directly via syscall stubs — bypassing user-mode hooks and EDR detours.

Defense in Depth

Meridian layers multiple protections so that if one is defeated, others remain. Anti-debug checks, IAT integrity verification, Authenticode self-validation, and offline grace caches all work together to keep your software secure.
