Continuous Domain & Email Posture Monitor
A SaaS that continuously monitors personal and small business custom domains. It tracks DNS records, SPF/DKIM/DMARC validity, WHOIS privacy status, and TLD reputation to prevent domain hijacking and email spoofing.
Por que isso importa
You rely on a custom domain for your primary email, meaning your entire digital life is tied to it. If someone compromises your registrar or alters your DNS records, they control your password resets across all services. Setting up a secure stack with separate registrars, DNS managers, and email hosts requires precise configuration of complex authentication records. Existing guides tell you what to do, but no tool actively watches your configuration to ensure your privacy protection hasn't lapsed, your authentication records haven't broken, and your emails aren't silently dropping into enterprise spam folders because of a poor domain reputation.
- · Feito para Privacy-conscious individuals, solo developers, and small business owners who use custom domains for critical accounts..
- · Monetização mais provável: SaaS subscription (freemium model).
