DMARC Records Tools
Hunt down hidden security loopholes in your email authentication. Automatically scan your DNS for subdomain hijacking vulnerabilities, partial enforcement flaws, and reporting blindspots to secure your domain against cyber threats.
A syntax-valid DMARC record can still contain massive security loopholes. We inspect your DNS for configuration weaknesses such as Subdomain Hijacking (sp=none), Partial Enforcement limits, Reporting Blindspots, and overly relaxed alignment settings.
Our Inspector acts as an automated cybersecurity auditor. We hunt for the specific logical misconfigurations that hackers exploit to bypass email authentication.
p=reject policy is useless if you leave sp=none. Hackers will simply spoof admin@mail.yourdomain.com to bypass the root policy. We flag this critical loophole.pct=50 means half of all spoofing attempts are allowed through. While useful for temporary testing, leaving it active long-term is a major security flaw we detect.rua= tag, you have zero visibility into who is abusing your domain. We audit your URIs to ensure you aren't flying blind.adkim=r) is standard, strict security environments require exact matches. We highlight your alignment posture so you can tighten it if needed.p=none to gather data but never upgrade. We aggressively flag p=none as a high-threat vulnerability since it offers zero protection.fo=) can flood your inbox or leak sensitive data. We inspect and advise on optimal settings.Your feedback has been submitted successfully. We appreciate your help in improving our tools.
