Email & Messaging Security

It reads the public DNS records for SPF, DKIM, DMARC, DNSSEC and related protocols, scores the result, and shows the gap between what a domain publishes and what actually stops spoofing. It gives fix steps you can hand to whoever runs your DNS. It is free, needs no signup, and is open source. There is also an anonymous MCP server at seclens.one/mcp so AI agents can run the same checks.
