How it works
Just because the internet is stateless, it doesn't have to be lawless.
Proofmarked operates as a B2B2C SaaS platform that goes beyond domains and SSL/TLS certificates to make it clear if a URL has been authenticated & authorized by the organization the user intended to interact with, or not.
