FAQ

How does GuardScript work?

You give GuardScript the URL of the Javascript file that you want to monitor.
GuardScript monitors regularly this file and detects any modification GuardScript sends you an email if the file is modified. The mail contains a complete report of the modifications made.

How do you detect the modifications?

We compute the hashes of the files regularly. If only one character in a file changes, his hash will change.

What's the difference with Subressource Integrity

Subresource Integrity (SRI) is a security feature that enables browsers to verify that resources they fetch (for example, from a CDN) are delivered without unexpected manipulation. It works by allowing you to provide a cryptographic hash that a fetched resource must match. (Definition of Mozilla)
GuardScript is for when Subressource integrity is not possible or not implemented, which is most of the time for SaaS services.
