Does this sound familiar?

"DMARC still failing even though SPF and DKIM pass — and I don't know why."
"We have a gateway installed but I'm not confident it's actually enforced."
"I can't clearly diagram our mail flow, which means I don't fully control it."
"Finance almost got hit by invoice fraud. I need to prove we're protected."

Who it's for

Built for the person responsible for M365 email at an SME

IT Manager / IT Lead

On the hook when email breaks or someone gets phished. Needs a repeatable framework and checklists — not more theory.

MSP / Consultant

Run the 30-minute exposure check across every client. Use the worksheets as your internal playbook. Buy once, reuse often.

Owner / Ops

Concerned about invoice fraud and spoofing. Wants a plain-English baseline and evidence that the basics are covered.

How it works

From "not sure" to "enforced" in one sitting

  1. Run the 30-minute exposure check Score the tenant and identify the highest-risk gaps first.
  2. Fix the fundamentals SPF, DKIM and DMARC with a safe rollout path to enforcement.
  3. Validate mail flow Prove your gateway and connectors are enforced (and not bypassed).
  4. Lock in protections Baseline hardening, audit checks, and alerting you can actually maintain.
  5. Document it Use templates to record evidence and communicate changes internally.

If you need hands-on help during or after, use the Get help link and we can jump on it.

What format is the kit?

A single PDF, 30 pages. All worksheets and templates are included within the document — no separate files or logins required.

Can I use it across multiple clients?

The standard licence covers use within your own organisation. MSPs wanting to use it across client engagements should contact us — we offer a multi-client licence at a higher price point.

Will it get updated?

Yes. Purchasers receive update notifications by email. Updates within the current major version are included.

What's the refund policy?

If the kit isn't what you expected, contact us within 7 days and we'll refund you. No awkward questions.

Is this relevant outside Ireland?

Yes. The content is Microsoft 365 platform-specific, not geography-specific. Relevant for any SME running M365.

I need hands-on help, not a PDF.

That's what the incident response service is for. Get in touch and we can discuss what you need.
