Protocol Sanitization
Control-plane events are normalized to reduce automation artifacts that emerge through protocol-level inspection.
Product: Stealthium
The Patching Era Is Over
JavaScript
Chromium
Evasion
Stealthium is a custom Chromium fork with evasion engineered inside the browser stack, not bolted on with scripts. For environments where failure is not acceptable.

The Problem
Accumulates
Anti-bot vendors operate with billions in funding, privileged visibility across the web, and continuous model-driven detection. The web platform keeps expanding: new APIs, new entropy surfaces, new telemetry.
2020-2022
Script Detection
Basic automation property checks. Easily patched.
2022-2024
Behavioral Fingerprinting
Multi-surface correlation, timing analysis, ML classifiers.

Architecture
Solve It Where
Signals Generate
Stealthium implements evasion inside Chromium and V8, where feature exposure, execution semantics, and rendering behavior originate. Not simulated. Enforced.
Layer 3: Script Injection
Patching Cannot Reach Deep Signals
JavaScript patches sit above the engine. They cannot control V8 timing, renderer micro-differences, or protocol artifacts. Every patch creates new surface for correlation.
Layer 2: Framework Control
CDP and Control Planes Leak
Automation frameworks control browsers through protocols never designed for stealth. Command patterns, timing signatures, and state changes become detectable at scale.
Layer 1: Native Implementation
Coherence Enforced at Origin
Stealthium modifies Chromium and V8 directly. Fingerprinting control, behavioral consistency, and artifact elimination happen where signals are generated, not where they are observed.
V8 Semantics
Renderer Stack
Network Layer
Capability Surfaces
Built for High-Scrutiny Targets
Stealthium handles browser surfaces as a coordinated system instead of isolated patches. These controls reduce correlation failures under active defense.
Execution Context Control
On-page execution defaults to controlled browser contexts to minimize leakage between automation logic and page code.
Browser Surface Coherence
Navigator, runtime, and rendering layers stay aligned to avoid contradictory states that high-scrutiny targets flag quickly.
GPU and Canvas Alignment
Graphics-related outputs remain synchronized with the broader identity profile to prevent renderer-level outliers.
WebRTC Synchronization
Network identity and browser signaling are coordinated so transport metadata does not drift from the assigned profile.
Fingerprint Distribution
High-dimensional fingerprint inputs are resolved into coherent launch profiles before automation begins.
Engineering Reality
Why Most
Solutions Fail
Chromium is one of the largest codebases on earth. Effective evasion requires preserving coherence across a shifting set of signals, without breaking real site functionality.
Fingerprinting Is Multi-Surface
Modern detection combines engine-level behavior, rendering surfaces, API consistency, protocol artifacts, and cross-session correlation. Patching one surface leaves dozens exposed.
V8 Timing Canvas Entropy WebGL Traits TLS Signature
Chromium Moves Fast
Every upstream change can introduce new observable behavior. "Stale" builds stand out. Maintaining parity with Chrome's release train is baseline hygiene for operating under scrutiny.
Parity: ~48 hours
| Chrome releases every 4 weeks Maintenance Is The Product
Stealthium is built as a long-term engineering program. Continuous updates, upstream parity, security posture maintenance, and new evasion capabilities as the ecosystem shifts. This is not a feature, it's the foundation.
