About Guardio

Guardio is a browser extension and mobile layer for people, not CISOs. It blocks phishing, fake shops, and AI-generated scams in the tab, then adds posture extras such as leaked-document and missing-MFA checks.

Three years of 100% ARR growth got it to a consumer cyber business that enterprise vendors still ignore, which is exactly the gap it is filling.
