# Checks

To prevent abuse, Gatekeepr performs a series of checks across three primary signals: Email, IP Address, and User Agent.

Each signal goes through multiple layers of inspection to determine potential abuse or fraud.

# Email Checks

We analyze the submitted email address for formatting, legitimacy, and potential risk indicators. View email checks.

We extract and validate the domain from the email to assess age, existence, and compliance. View domain checks.

The IP address is checked for network type, anonymization services, and reserved ranges. View IP checks.

We evaluate the user agent string to detect suspicious patterns and outdated or automated browsers. View User Agent Checks.
