Why we’re called Seatbelt
Gothenburg, 1959
Volvo gave the seatbelt away for free. We believe email security should work the same way.
In 1959, Volvo engineer Nils Bohlin invented the modern three-point seatbelt — one of the most important safety innovations in history.
Volvo could have kept the patent for itself. Instead, they made the technology available to every car manufacturer for free because protecting lives mattered more than protecting profits.
At Seatbelt Security, we believe email security should work the same way.
Small businesses are under constant attack. Criminals spoof company domains, send fraudulent invoices, steal customer trust, and cause legitimate emails to land in spam. Many businesses do not realize they are vulnerable until after the damage is done.
Large enterprises spend millions protecting their email systems. Small businesses are often left exposed because email security feels too technical, confusing, or expensive.
That is why Seatbelt Security created a simple Email Security Scanner and Guided Protection Wizard built specifically for small and medium-sized businesses.
In as little as 20 minutes, we help businesses implement the same core protections trusted by major enterprises:
- SPF
- verifies who can send email from your domain
- DKIM
- confirms your emails have not been altered
- DMARC
- helps you spot, and then stop, criminals impersonating your business
No advanced technical skills required.
Your email reputation is your digital seatbelt. You would never drive without a seatbelt, so why run your business without protecting your email?
Our mission is simple: make enterprise-grade email protection accessible to every small business.
Because one prevented attack could save a business.

Seatbelt Security Buckle Up Your Email.
Three points of protection
Small businesses are a frequent target for email spoofing and phishing. Protecting yourself is easy with Seatbelt Security.
SPF
Lists your approved sending services
Lists the services allowed to send email as your domain, so receivers can spot senders that aren't on it.
DKIM
Helps receivers check signed email
Your email provider signs outgoing messages with its own key. Receivers can check that signature to help verify where the mail came from.
DMARC
Shows who sends email as your domain
Shows you who is sending email as your domain, so you can spot impersonation early. Seatbelt starts in monitoring mode, so nothing is blocked yet.
A short call to walk through your setup, without jargon.
Seatbelt Security assures every business has critical and fundamental email protection.
Whether you’re running a tech startup or a taco truck. Could your small business afford to pay hackers hundreds of thousands of dollars? Or lose a contract due to email spoofing?
