Stop email spoofing
before it stops your business
DMARC Shield watches your domain 24/7, flags problems in plain English, and guides your fix — so your customers always get the real you.
How it works
Three steps. No DNS expertise needed.
We scan your domain
We check your SPF, DKIM, and DMARC records and show you what's missing or misconfigured — in plain language.
We monitor daily
Every day we check your DNS records and incoming DMARC reports. If something changes, you'll know within hours.
We guide the fix
From a simple record update to a full DMARC policy rollout, we give you the steps or coordinate with your IT provider.
See every detail

Built by S-Tech Solutions
S-Tech Solutions is a South African IT services company specialising in cloud infrastructure, email security, and managed services for businesses across Africa and beyond.
DMARC Shield was built because too many businesses — from startups to enterprises — are exposed to email spoofing and don't know where to start. We make DMARC accessible, safe, and actionable without requiring a DNS expert on staff.
Trusted by businesses like yours
Companies of all sizes use DMARC Shield to protect their domain reputation and customer trust.
"We had no idea our domain was being spoofed. DMARC Shield found it, showed us exactly what was wrong, and guided us through the fix. Within a week our email was fully protected."
"The monthly reports alone are worth it. We can see exactly which services are sending email on our behalf, and the threat alerts caught a spoofing attempt within hours."
"Switching from p=none to p=reject felt risky, but the rollout wizard walked us through it. We monitored for two weeks, verified all senders, and made the switch with confidence."
