About GradeLock

GradeLock gives small-business owners a fast, understandable view of security signals that are already visible on the public internet. Enter a domain and receive an A–F report card without creating an account.

We focus on practical gaps: email impersonation defenses, SSL/TLS health, publicly recorded services, and known breach exposure. Each finding is explained in plain English and paired with a useful first step.

The product is passive by design. It relies on public records and existing scan data rather than actively probing a domain, making it safe to check your own business, a vendor, or a competitor.
