What we saw
What we look at
- Your SPF record, the list of services allowed to send mail as you.
- Your DMARC policy, which tells other mail servers what to do with mail that fails those checks, and where the reports go.
- DKIM signing for Microsoft 365 and Google Workspace, and who handles your mail.
Website
- Server headers. Many hosts name the exact PHP version on every page they send.
- Your homepage code, which often names the CMS that built it and its version.
- WordPress fingerprints: the readme file and public API that every WordPress install ships with.
- Whether a firewall or CDN, like Cloudflare, sits in front of your site.
We only read what your domain already shows the public: its DNS records and public web pages. We never send exploit traffic.
