The Firewall for
Your Inbox.
Sanitize incoming traffic before it touches your personal data. Deploy prot4 as the ultimate firewall for your inbox to route, scrub, and shield your digital identity.
Route Configuration
// USER_CONTROL: ENABLED
Complete granularity. Toggle protection levels for every individual route you create. You decide exactly what passes through the firewall.
AI_SCRUBBING
Neural network analysis of message body and headers. Detects social engineering and zero-day phishing.
DOMAIN_VERIFY
Strict enforcement of SPF, DKIM, and DMARC. Drops connections from unverified senders immediately.
CUSTOM_DOMAIN
Route traffic through your own domain (e.g., @yourcompany.com) while maintaining full firewall protection.
ALTERNATIVE: BULK SHIELD
Don't want to create aliases? Configure a single wildcard redirect in your email client to send everything to a specific prot4 route.
Zero Persistence.
We use a RAM-only architecture. Emails exist in volatile memory solely for the milliseconds required to process them.
