Show HN: I built a free email security checker for small businesses

[minhajulmahib]

A free tool that checks SPF, DMARC, DKIM, SSL and MX records for any business domain in 30 seconds. No backend — just HTML and Google's DNS-over-HTTPS API.

Built because 7 in 10 small businesses fail basic email security checks and have no idea.

Security report for shielddeskhq.com 43 Security Score / 100 Vulnerable — Your domain can be spoofed.

Good catch — embarrassing that my own domain scores 43 on my tool. Fixing the DNS records now. Thanks for actually testing it.

hey, congrats on the launch, your own tool is flagging shielddeskhq.com at 35, worth a quick fix.

You're right — fixing it now. SPF and DMARC records need updating on my end. Appreciate you scanning it
