Pipeline

7-Stage Obfuscation Pipeline

Your code passes through 7 transformation stages, each adding a new layer of complexity

STAGE 1

Parse & Compile

Source code is parsed and compiled into an intermediate representation. Each build produces structurally different output from the same input.

STAGE 2

Transform

Multiple transformation passes inject complexity, fuse instruction sequences, and restructure control flow to resist static analysis.

STAGE 3

VM Generation

A unique virtual machine is generated per build with randomized instruction encoding and multiple dispatch strategies.

STAGE 4

Encryption

Constants and data are encrypted with state-dependent decryption. Correct values only emerge during proper execution order.

STAGE 5

Emission

Output varies structurally across builds with non-uniform code generation patterns. No two outputs share the same structure.

STAGE 6

Anti-Tamper

Integrity verification is woven throughout execution. Tampering silently corrupts state rather than producing error messages.

STAGE 7

Output Hardening

Final output is hardened against automated cleanup, formatting tools, and structural analysis.

Intensity Levels

Choose Your Protection Level

Each level includes everything from the previous tier. Higher levels increase cost of analysis, not just output size.

How Vanguard Compares

Standard VM obfuscators produce output that can be devirtualized with a generic lifter. Vanguard is designed so that approach doesn't generalize.

Targets

Built for Every Environment

Roblox

Default

Server-side scripts with full anti-tamper, environment checks, and Studio blocking. No loadstring dependency.

Roblox Executor

Executor

Client-side injection with loadstring support and Roblox API access. Optimized for executor environments.

Luau

Portable

Portable vanilla Luau with source compression via loadstring. Runs anywhere Luau does.

Deep Dive

Continuation-Based VM

A fundamentally different dispatch model that eliminates the central loop attackers rely on

Register-Based (Standard)

Central dispatch loop with a single control variable
Single point of observation reveals all execution
One breakpoint captures full execution trace
Vulnerable to generic automated devirtualization

Continuation-Based (Vanguard)

No central loop. Execution flows directly between handlers
No single point of observation — distributed execution across many independent units
Execution history affects future behavior — static traces don't generalize
Multiple transfer variations resist pattern-based analysis
Runtime behavior evolves — recorded traces become stale
Integrity is distributed — modifying any part affects all subsequent execution

The Tradeoff

~30-45% slower execution. That's the cost of fully distributed dispatch with no central control point.

When to Use It

Production code where analysis cost justifies runtime overhead. Available at Heavy+ intensity or via the --continuation-vm flag.

Start Protecting Your Code Today

Vanguard increases the cost of reverse engineering by requiring analysis to preserve execution state, structural integrity, and runtime topology simultaneously.
