The entry explains that PrestaShop as open source does not always protect against vendor lock-in, i.e. dependence on a single vendor. Risks arise with abandoned modules, lack of updates, weak code or encrypted solutions without a back-up plan. PrestaShow encrypts some modules through ionCube, but guarantees that this will not become a problem for the customer. It provides updates, development, compatibility with new versions of PrestaShop and PHP, and an exit plan if a module stops being developed.
