DMARC Shield

Stop email spoofing before it hits your customers — clear domain health, guided fixes, and ongoing monitoring.

Email authentication that works in plain language

DMARC Shield watches your domain, flags SPF, DKIM, and DMARC misconfigurations clearly, and tells you what to fix — so invoices, logins, and support mail still come from you.

Built by S-Tech Solutions as part of the KairOS product family, it is the product home for domain scans, monitoring plans, Fix Assist cleanups, and multi-domain programmes for security and IT teams.

Why organisations choose it

  • Free SPF, DKIM, and DMARC scan — no signup required to see where you stand
  • Monthly status by email — who sent as you, what failed, and what to do next
  • Drift alerts — when DNS or policy weakens from a healthy baseline
  • Safe rollout — guided steps from p=none toward p=reject
  • Clear ZAR pricing — month-to-month self-serve, once-off Fix Assist, or quoted Enterprise

How it works

Three steps. You do not need to be a DNS expert.

We scan your domain

Check SPF, DKIM, and DMARC and show what is missing or wrong in clear language — starting with a free scan if you are not sure where you stand.

We keep watching

Scheduled DNS checks and DMARC report processing watch for drift. When posture slips, you get an alert instead of discovering it after customers do.

We show the fix

Monitor includes next steps. Managed and Business add DNS change guidance, safe policy progression, and help coordinating your IT provider.

What is covered

Concrete outputs you can act on — not raw DMARC XML dumps

Monthly domain summary

Emailed on your plan cadence. Covers senders, pass/fail, and next actions — the same story as the client portal.

Alerts when posture slips

Broken DNS, weakened policy, or monitoring gaps surface early — before delivery problems hit customers.

Safe DMARC rollout

Step from monitoring-only toward quarantine and reject while watching sender impact. Included on Managed and Business.

Who sends as you

Find CRM, invoicing, marketing, and form systems using your domain so authorised senders stay aligned.

DNS health checks

SPF, DKIM, DMARC, plus BIMI, MTA-STS, TLS-RPT, and ARC readiness by plan — with free tools for one-off checks.

Work with your IT provider

Change guidance and supplier coordination so DNS updates land safely. Support minutes on Managed and above.

Choose a path

Self-serve if you look after your own domains. A programme path if security or IT owns several brands.

For my business

One or a few domains: monthly status by email, alerts when something slips, and optional guided DMARC rollout. Priced in ZAR, month to month.

  • Free domain scan first
  • Monitor, Managed, and Business plans
  • Fix Assist for a once-off cleanup
  • Client portal at dmarcshield.app

For my organisation

Several brands or subsidiaries under one programme — role-based access and capacity sized with security and IT, not a spreadsheet of reports.

  • Multi-brand email authentication
  • Business self-serve or quoted Enterprise
  • Talk to sales — no silent checkout for Enterprise
  • Enterprise portal at enterprise.dmarcshield.app
