Abstract: Computer system, methods, and non-transitory storage medium for protecting a client device that is browsing a website from undesired actions of third-party software. Virtual iFrame Containment Enclosure (VICE) code (e.g. JavaScript/WebAssembly) is tailored per website that defines a set of policies of what each third-party code can and cannot do. The server also tracks and analyzes data reports from the websites, and provides reports and alerts to website administrators. Therefore, a browser on a client device visiting the website, and thus executing the VICE code that is tailored for that specific website, is protected from the third-party code, without hindering the proper action of the third-party software and without the third-party knowing that their code was monitored and controlled.
