What to expect
An honest snapshot
GradeLock reports only what its data supports. It is a practical first look—not a penetration test or a promise that a business cannot be breached.
Passive by design
Checks rely on DNS, certificate records, breach counts, and existing public internet-scan data.
Useful, not cryptic
Every failed item includes a plain-English explanation and one practical next step.
Your report card
Four signals. One grade you can understand.
GradeLock turns technical public signals into a screenshot-ready result and a short list of what to fix first.
Sample result
B+
Your site encrypts traffic, but email authentication needs attention.
- 01
Email impersonation
See whether SPF, DKIM, and DMARC help stop attackers from sending email as your domain.
- 02
SSL and TLS health
Catch expiring certificates, weak protocols, and missing browser security headers.
- 03
Public exposure
Review open services found in existing public internet-scan records—without GradeLock actively probing the domain.
- 04
Known breach count
Learn whether email addresses associated with the domain appear in known breach data, shown as a count only.
Pricing
The grade is free. Full stop.
GradeLock v1 has no paid tiers, account limits, or surprise checkout. Future monitoring and hands-on remediation will be clearly separated from the free score.
