Business email is one of the most important identities a company owns. A compromised mailbox can expose customer conversations, invoices, password resets and internal approvals, so email security should combine account controls with correct domain authentication.

Protect accounts with MFA

Enable multi-factor authentication for staff and especially for administrator, finance and executive accounts. Remove unused accounts and avoid sharing administrator credentials.

Understand SPF, DKIM and DMARC

SPF identifies authorised sending systems, DKIM adds a cryptographic signature to outgoing mail, and DMARC tells receiving systems how to handle messages that fail authentication while providing reporting options.

Review forwarding and mailbox rules

Unexpected forwarding rules can silently copy messages to external accounts. Include rule checks in account reviews and incident response.

Use the free DNS & Email Checker

Run the Techvenation DNS & Email Checker to review MX, SPF, DKIM and DMARC records. The result is a diagnostic starting point rather than a guarantee that every message will be delivered or blocked.

Train staff for real business scenarios

Teach staff to verify bank-detail changes, urgent executive requests, password-reset links, QR codes and unexpected shared documents using a second trusted channel.
