phpSHIELD is a product originally produced by Alexander Belonosov and Sergey Egorov from Russia. Alex and Sergey joined forces with Inovica Ltd, a UK company specialising in online businesses, and we integrated their system with our existing SourceGuardian PHP Encoder software. Our two PHP Encoding products are similar, but they target different markets. phpSHIELD is an excellent product for just encoding your files if you don't require any time limiting, IP/Domain locking or the licensing features contained within SourceGuardian.
