Zend Technologies Ltd. is a world wide web infrastructure software company with headquarters in Cupertino, California, USA and has offices in Israel, France, and Germany. Zend Open Source Systems Japan, currently owned by Turbolinux, is a representative of Zend Technologies in Japan.

Zend is best known for its founders Andi Gutmans and Zeev Suraski who, along with other Israeli graduates of the Technion and Rasmus Lerdorf, have created PHP. The company's operations are currently centered on the development of products relating to the development, deployment and management of business critical PHP based web applications, including Zend Studio.

The name "Zend" is a portmanteau of the names of its founders, Zeev Suraski and Andi Gutmans.

In 1997, Zeev and Andi rewrote the parser behind Rasmus Lerdorf's PHP-FI. The result was released as PHP 3.

In 1998 they redesigned that parser completely, and named it the Zend Engine. PHP 4 was based upon the first version of the Zend Engine and was extremely successful.

Zend also provides a PHP Certification Test and certifies people succeeding on the exam as Zend Certified Engineers (ZCE). To help Zend Certified Engineers gain employment, Zend lists all the persons whom have passed the Zend PHP Certification Exam in its directory, Yellow Pages for PHP Professionals. Also, they allow ZCEs to place a ZCE logo on their personal web site/resume.

Zend Platform is a product that runs on a web server, monitoring PHP applications and reports on performance and possible problems. Zend Platform can be used in conjunction with Zend Studio to do remote debugging and profiling of PHP applications in their native server environment.
