Email is attacked every 11 seconds.
SeatBelt Security buckles up your email.
Don’t be one of the 24M victims this year. The right security tools probably came with your email, they just need to be configured right. The first step is your Sender Policy Framework (SPF). We help you understand if its setting leaves you vulnerable and, if so, we’ll fix it for free — in a 20-minute call.

Features
Real Cyber Protection You Already Own
SMBs are attacked every 11 seconds. Protecting yourself is easy with SeatBelt Security.
SPF
Protects you, your customers and your partners
Keeps criminals from faking your email address to trick customers, vendors, or staff. SPF is like a party’s guest list, not just anyone can get in.

Testimonials
Built for everyday businesses
Trusted to Keep Inboxes Safe and Secure.
“SPF? DKIM? DMARC? Who knew what those were and that we *already* owned them?”
Our clients were suddenly getting suspicious emails from us that we never sent! It cost us a couple of clients, but almost cost us the whole business. These guys are expert and easy to work with. Trust them.
Michael Smith
Product Owner at InnovateX
“The hackers are getting so good, you need someone like SeatBelt on your side.”
Our business is seasonal, so at year’s end we bring in a bunch of temps. We don’t have the time to train them all on security protocols, our system has to be on high alert — now it is.
Jessica Brown
Team Lead at BrightSolutions
“Such a simple thing made such a difference. Why leave yourself vulnerable, when the fix is so quick and easy?”
As a business owner, I have too much to think about 24/7. Now, this is one thing that’s off my mind. Buckle in, SeatBelt Security is here to help.
James Carter
Project Manager at TechNova
“SeatBelt Security made it all so easy and affordable.”
We had no idea how vulnerable we were until we used their app, and they showed us how easy it’d be for someone to spoof or phish us. Our entire business runs on email and now we can see how much safer we are. Thanks SeatBelt team!
