If you are still using a hosted email service that is based on IMAP (or POP3) it is time to consider moving onto Microsoft 365 Exchange Online, and benefit from the improved security.

I have seen many customers on IMAP experiencing identity theft where user credentials have been gained, and used maliciously. A man-in-the-middle attack involving false invoicing can cost a business many thousands of dollars. IMAP mailboxes cannot be protected by MFA.

IMAP Email Platform Security Risk

Move to Exchange Online and move away from basic protocols like IMAP and POP3, and move to modern authentication with MFA. Add in extra controls for SPF, DKIM and DMARC to really up your security posture.

Sometimes our client is using IMAP without realising it, and is unaware of how exposed they are to security incidents, having no visibility of these. Office 365 provides richer security alerts, and optionally more advanced hygiene with the Defender for Office subscription plans.

Migrate off IMAP to O365

I am surprised by how many businesses are still using older hosted mail providers – the cost of these services are often similar to Microsoft 365, so why stay on them waiting to be hacked. Contact us today for a quote to migrate from hosted IMAP to Microsoft 365.
