Edge Engine Capabilities

Intelligent Email Risk Protection at Edge Speed

Explore the algorithms and heuristics protecting your signups against burner domains, duplicate farms, and fake registrations.

🛡️ 3-State Policy Action

Never drop valid customers. Clear categorical actions: allow (clean), review (apply friction/OTP), and block (high confidence disposable/invalid).

⚡ Hundreds of Thousands of Disposable Domains

Real-time edge classification identifying hundreds of thousands of verified temporary and throwaway email domains, synced daily from vetted threat feeds.

🔍 Rotating Burner Network Detection

Identifies disposable mail infrastructure used by burner services that frequently rotate custom apex domains to bypass simple blocklists.

✨ Canonical Alias Normalization

Deterministic alias stripping for Gmail, Outlook, Yahoo, and ProtonMail. Stops attackers creating 1,000 trial accounts using dot tricks or plus aliases.

💡 Typo Suggestion Engine

Detects unintentional user typos (e.g. gmial.com → gmail.com) to recover lost signups before activation emails bounce.

🔒 Zero-Plaintext PII Storage

Strict GDPR-compliant architecture. Emails are validated in volatile memory; persistent audit logs only record SHA-256(email) and domain.

Deterministic 3-State Recommendation Model

CheckSignup provides actionable verdicts so you never have to guess whether to reject or challenge an incoming registration.

1. ALLOW (Score 0-34)

Legitimate business domains and verified personal webmails (Gmail, Outlook). User proceeds immediately with zero friction.

2. REVIEW (Score 35-89)

Forwarding relays, role-based mailboxes, or possible typos. Require 2FA OTP or withhold promotional credits without blocking.

3. BLOCK (Score 90-100)

Confirmed burner domains, invalid RFC syntax, or unroutable mailboxes. Block instantly at the edge before sending OTP.
