E-mail security made visible

E-mail is still the most common attack vector globally. Most attacks succeed not because organizations don't care, but because they can't see what's going on. MailReport brings visibility into a part of IT that's normally stressful and reactive. You get early warnings, clear explanations, and a historical trail of every meaningful signal in your e-mail ecosystem.

E-mail security isn't a single thing.

It's a constellation of mechanisms working together.
MailReport pulls these together and makes them visible.

DMARC

MailReport processes DMARC aggregated and failure reports and presents them in an understandable, visual way. No unreadable XML. Just clarity about legitimate vs. illegitimate traffic, authentication results, and unexpected senders.

  • Raw RUA reports
  • Aggregated reports
  • Forensic reports

SPF

MailReport provides comprehensive insights into your Sender Policy Framework (SPF) implementation, helping you understand and optimize your email authentication strategy. By continously monitoring, interpreting and resolving your SPF records in DNS, any issues can be quickly identified and addressed.

  • SPF linting coming soon
  • Syntax, semantic & policy validation
  • Multiple records detection

TLS

E-mail security isn't only about sender validation — it's also about transport security. MailReport collects and displays SMTP TLS reports so you can see which servers negotiate secure connections and where misconfigurations exist.

Part of this are actual TLS versions and presented certificates. MailReport continuously monitors these, so you can be sure your e-mail is being delivered securely.

  • Aggregate TLS data
  • TLS version monitoring
  • Certificate validation

DNS

Continual monitoring of DNS records relevant to e-mail infrastructure. Monitored record types include DMARC, DKIM, SPF, MX, NS, ADSP, TLS-RPT, MTA-STS, BIMI, and TLSA. If something changes, whether intentional or accidental, MailReport alerts you. No more configuration drift.
