Looking for software protection solution for your Python applications?

Python is a popular programming language used by developers around the world. It is widely used in various industries, including web development, data analysis, machine learning, and artificial intelligence. However, with the rise of software piracy, Python developers need to protect their intellectual property by implementing copy protection mechanisms. In this article, we will discuss the importance of Python software copy protection and the methods that developers can use to protect their Python code.

Why Protect Against Software Piracy?

Python software protection with PC GuardSoftware piracy is a serious concern for software developers, as it can lead to revenue loss, decreased market share, and damage to their reputation. Piracy can also cause security risks, as pirated software may contain malware or viruses that can harm users' systems. Therefore, software copy protection is essential for protecting intellectual property and ensuring the security of software programs.

Python developers can help prevent unauthorized access and modification of their software programs, while also protecting their revenue streams and reputation.

PC Guard software protection system will protect your Python software with advanced cryptography, anti-cracking, anti-reverse-engineering and software copy protection techniques.

Easily implement almost any software protection scenario: demo (number of days, period, number of runs, timer), demo extension, activation, permanent license, limited license (number of days, period, number of runs), license extension, license removal, license transfer, password protection, serial numbers, IP filtering, custom features, custom counters, custom dialogs, USB device (USB Flash / USB HD / USB NIC MAC) locking, network licensing.

Use PyInstaller or Nuitka to package your code and then PC Guard to additionally encrypt and protect packaged Python applications.


Both One-Folder (recommended) and One-File PyInstaller bundling methods are supported. PC Guard's advanced overlay management (AOM) and internal overlay encryption are by default enabled for PyInstaller created applications. This unique protection solution offered by PC Guard means that PyInstaller data which contains actual Python code of your application and is attached to PyInstaller loader stub (exe) will also be additionally encrypted.

PyInstaller bundled applications can be successfully digitally signed after protection.

PC Guard for Win32 (.NET) supports PyInstaller Python 2.7 and 3.x 32bit applications and PC Guard for Win64 (.NET64) supports PyInstaller Python 3.x 64bit applications.


PC Guard also includes out-of-the-box support for Python applications created by Nutika. Nuitka created applications have different structure so AOM and internal overlay encryption are not applicable for these applications.

Protected Python applications will work on all 32-bit and 64-bit desktop and server Windows operating systems.

By default, no source code changes or programming experience is required to accomplish professional software protection for your Python programs. PC Guard can by used by anyone, from absolute beginners to professional software developers.
