Protection layers

5 layers of analysis
on every email

Layer 1

Email Authentication

SPF, DKIM, and DMARC records verified against Cloudflare DNS — confirms the sender is who they claim.

Layer 2

Mercury-2 AI Deep Scan

Reasoning AI reads the email, writes a chain-of-thought, then judges: urgency manipulation, domain deception, impersonation.

Layer 3

Link Safety Scan

Every URL checked against VirusTotal (90+ engines), Google Safe Browsing, PhishTank, and URLhaus — in parallel.

Layer 4

Domain Age Intel

Domains registered days before an attack are a classic red flag. RDAP lookup catches them instantly.

Layer 5

Nigeria-Aware Engine

Trained on EFCC/CBN fraud patterns, BVN phishing, advance-fee scams, and fintech impersonation attacks.
