Email is still the backbone of business, and the number-one attack vector. We set up and secure Microsoft 365 and Exchange Online so your mail, calendars and collaboration just work, and so phishing and spoofing do not. From a new tenant to a hybrid Exchange environment, we handle the design, migration and hardening.
What we deliver
- Microsoft 365 tenant setup: domains, identity, licensing and baseline policies.
- Exchange Online and hybrid Exchange configuration and coexistence.
- Mail-flow hardening with SPF, DKIM and DMARC to stop spoofing.
- Mailbox migration from on-premises or other providers, with no data loss.
- Security: MFA, Conditional Access, anti-phishing and Secure Score improvements.
- Teams, SharePoint and OneDrive setup and governance.
Our approach
We plan the tenant and mail flow carefully, pilot with a small group, then migrate in controlled batches so email keeps flowing throughout.
- Assess. Review domains, mailboxes, current mail flow and security.
- Prepare. Configure the tenant, DNS, SPF/DKIM/DMARC and security policies.
- Migrate. Move mailboxes in batches, verified as they land.
- Harden and optimise. Enforce MFA, tune anti-phishing, right-size licences.
Why it matters
A default Microsoft 365 tenant is not a secure one. Correct mail authentication and identity hardening, following Exchange Online best practice, stop the spoofing and account takeover that lead to fraud and data loss, while keeping email reliable for your team.
Outcomes you can expect
- Reliable email and collaboration on a clean, well-configured tenant.
- Spoofing and phishing sharply reduced through SPF, DKIM and DMARC.
- Mailboxes migrated with no data loss and minimal disruption.
- Stronger identity security and a higher Microsoft Secure Score.
