What is Prometheus Shield?

Prometheus Shield is professional Python source code protection software for Windows. Protect your Python applications from reverse engineering, decompilation, and unauthorized distribution.

Key Features:

  • Multi-layer obfuscation (control flow, variable renaming, string encryption)
  • AES-256 bytecode encryption
  • Hardware-locked license enforcement (machine fingerprinting)
  • Time-limited and feature-gated license options
  • Standalone EXE compilation — no Python runtime required on end-user machines
  • Works with PyQt, Tkinter, Django, Flask, and all major frameworks
  • License server integration included
  • CLI and GUI interfaces

Perfect for Python developers shipping commercial software, SaaS products, desktop applications, and enterprise tools who need to protect their intellectual property.

Alternative to PyArmor, Nuitka obfuscation, cx_Freeze, and PyInstaller (with protection layer). One-time purchase from $49 — no subscriptions.
