Customer Quote

When it comes to ROI, we consider our investment in Zend technology to be a benefit on several fronts. It is easy to manage the PHP stack, and the strength of the error detection and reporting helps us reduce the time spent troubleshooting while increasing application availability and responsiveness. With session clustering alone, Zend more than paid for itself the moment we flipped the switch.

Eric LongSr. Manager, E-Business, Levolor

Zend Server paid for itself by virtue of the issues we found and fixed in the first week alone a benefit that is magnified exponentially as our e-commerce application grows.

Josh ButtsDirector of Web Development, Offers.com

With Zend Server, we achieved faster and smoother installations of our software technology stack, and saw more reliability and robustness in daily operations.
