Zend GuardTM is the first Electronic Licensing solution for the PHP marketplace. It includes the Encoding solution that pioneered PHP intellectual property protection.

Unprotected intellectual property, in the form of plain text PHP scripts and software without license restrictions, can be copied, modified, and retained by someone else. It is available to your competitor, to hackers and even to developers at customer sites.

Zend GuardTM provides tools that significantly lessen risk to your intellectual property. It is designed to prevent your property from being viewed or modified.

Software piracy losses run in the billions. Estimates place it at $59 billion in the last five years. This translates into lost opportunities and diminished sales.

Zend Guard maximizes software profitability by:

• Limiting unauthorized duplication or use of your applications.

• Ensuring that only licensed customers use your products and that they remain within the terms of your license.

• Offering flexible licensing terms that make your software products more attractive, increase sales, and improve customer satisfaction.

• Increasing conversion rate from evaluation to licensed product.

• Preventing other people from changing your code (all files are rendered as un-editable and external changes will corrupt the code) protecting the files against external tampering.
