Zend Guard, formerly known as Zend Encoder, protects your commercial PHP 4 and PHP 5 applications from reverse engineering, unauthorized customization, unlicensed use and redistribution.
Zend Guard, likes its predecessor Zend Encoder, allows Independent Software Vendors (ISVs) and IT managers to safely and confidently distribute and manage the deployment of their PHP applications while protecting their source code.
Zend Guard 5 not only encodes the source code of your application, but also increases source code protection through obfuscation of the various application name components.
Zend Guard 5 is the only product that obfuscates object oriented programs created with PHP 4 and PHP 5.
Enables PHP source code protection (against copyright infringement and reverse-engineering) of commercial PHP applications through advanced encoding and obfuscation technologies.
Provides IT Managers with a solution that prohibits modification of their internal PHP application source code so they can effectively support them.
Allows ISVs to impose a variety of licensing policies on commercial PHP applications.
Enables vendors to increase their revenue by choosing from a variety of licensing models such as concurrent users, time limited, segment of network, or server specific.
