About this Gig
Are your emails landing in spam, failing authentication, or is your Microsoft 365 tenant still on default settings? I set up and fix SPF, DKIM and DMARC, and harden Microsoft 365 against common attacks.
I am an engineer running a UK-registered company, with an MSc in Software Engineering, 8 years of programming and 10 years of system administration.
What I cover:
- SPF, DKIM and DMARC setup or repair for your domain and sending services
- MFA and Conditional Access review and setup
- Microsoft Defender for Office 365 policy review
- Mailbox auditing checks
- Secure Score review with a prioritised action list
- A clear written report of what I found and changed
How I work: I use automated, read-only audit scripts to collect settings, then review every result and make changes myself. Access is via a delegated or temporary admin account that you control, and it is revoked after delivery.
Please note: DNS changes need access to your DNS provider, or you can add the records I supply.
Message me before ordering if you are unsure which package fits.

FAQ
What access do you need?
A delegated admin relationship or a temporary admin account that you create and control. I ask you to remove it after delivery, and I confirm when I no longer need it.
Do you need my DNS login?
DNS changes need access to your DNS provider. If you prefer, I send you the exact records to add and then verify them.
Will my email stop working?
I start DMARC in monitoring mode and only recommend stricter policies once reports show your legitimate senders pass. Changes are planned with you first.
Do you use automated tools?
Yes. I use automated, read-only audit scripts to collect settings. Every result is reviewed by me, and every change is made by me.
Which licences do I need?
Basic works with any mail provider. Defender and Conditional Access features depend on your Microsoft 365 plan; I will tell you what your licences support.
Do you work with Google Workspace?
Email authentication, yes. The hardening packages are for Microsoft 365.
