Microsoft 365 Security for Businesses

Stop account takeover and email fraud by securing Microsoft 365 properly.

Most business cyber incidents start with a compromised email account. We review and strengthen your Microsoft 365 security settings so attackers find it much harder to get in.

Common problems we help with

  • Accounts without MFA
  • Legacy sign-in methods still enabled
  • Mail forwarding rules set up by attackers
  • No alerts for suspicious sign-ins

How Compufix solves it

We apply a practical baseline: MFA, blocking legacy authentication, alerting, mailbox auditing and sensible sharing controls.

Why Microsoft 365 security matters for local businesses

Compromised email accounts are behind many of the incidents small businesses experience, from fake invoices sent to customers to data being quietly copied. Businesses across Chester, Cheshire and North Wales often have Microsoft 365 security features available that were never switched on. We review what you have, explain the risks in plain English and apply the protections that make the biggest difference.

What you get

Security review

A check of MFA status, administrator accounts, sign-in policies, mailbox rules and sharing settings, with prioritised findings.

Multi-factor authentication

MFA rolled out to every account with a plan for staff who need help.

Conditional access

Where your licences allow, sign-ins restricted by device, location or risk.

Email authentication

SPF, DKIM and DMARC configured to reduce spoofing of your domain.

Safe sharing and data

External sharing set to sensible defaults, and alerts for suspicious forwarding rules.

Microsoft 365 Security FAQs

Does this guarantee we will not be hacked?

No provider can guarantee that. These controls significantly reduce common risks.

Isn't Microsoft 365 secure by default?

Microsoft provides strong security tools, but many are not fully enabled or configured for your business by default. Responsibility for account security and data protection sits with you.

Which Microsoft 365 licence do we need for better security?

Some features, such as conditional access and Intune, require Business Premium or add-ons. We will explain what your current licences include before recommending any change.

What happens if an account has already been compromised?

Contact us straight away. We can help secure the account, check for malicious mailbox rules and advise on next steps.
