iDelegate is built with Laravel, easily the best of the latest generation of web frameworks based on the PHP language. PHP has been around for a while and extensively used in development of many well known sites including Facebook, WordPress and Wikipedia. Laravel makes PHP applications secure through robust authentication and protecting them against many serious security risks such as SQL injection, cross-site request forgery and cross-site scripting.
iDelegate can talk to other systems too. Your users will be able to authenticate with OAuth providers such as Azure, G Suite and many others for a seamless single sign-on experience.
