MFA for Microsoft 365 & Azure
MFA can stop over 99.9% of all account compromise attacks for Irish SMEs
Protect your Irish SME from account compromise with robust Multi-Factor Authentication (MFA). Over 99.9% of identity-based attacks can be blocked by enforcing MFA across Microsoft 365 and Azure environments. Tier3Tech deploys and manages MFA for businesses in Dublin and nationwide, ensuring users stay secure without disrupting productivity.
What is MFA ( Multi-Factor Authentication ) ?
and How can it help Secure my Business?
MFA adds a second proof of identity beyond passwords. So even if cybercriminals steal login details through phishing or data leaks, they still cannot gain access. It is a core security requirement in every Microsoft security framework including Zero Trust.
Tier3Tech helps Irish SMEs implement MFA policies aligned with best practices for Microsoft 365, Office 365, Azure Active Directory, and hybrid environments.
Administrators can protect accounts with MFA
Secure privileged accounts such as IT admins, finance or HR with stricter protection layers.
Microsoft Authenticator App
Push notifications for fast, secure approval. Phishing-resistant security built into mobile devices.
Phone call as a second factor
Accessible for users without smartphones or when network reception is limited.
SMS as a second factor
SMS One-Time Codes is Flexible second factor for users who prefer text authentication.
App passwords for clients that don’t support MFA
Ensures legacy applications function securely even if they don’t support MFA.

Save time by bypassing MFA on trusted company devices or secure office locations.
