Multi-Factor Authentication (MFA)
Stop credential theft turning into a breach by requiring a second factor on every business sign-in.
Passwords alone are not enough to protect business systems
Multi-factor authentication asks users to prove who they are using more than just a password - an app prompt, security key or passkey. Even if a password is stolen or phished, the attacker still cannot get in.
- Blocks over 99% of automated account takeover attempts
- Protects Microsoft 365, remote access and finance systems
- Required by insurers, customers and Cyber Essentials
- MFA enforced for every user, not just administrators
- Admins and finance users on phishing-resistant methods
- Exceptions are rare, time-bound and formally approved
Is MFA enforced for every user and every administrator, with no unmanaged exceptions?

Understanding mfa
Passwords get phished, leaked and reused. MFA is the single biggest improvement most UK businesses can make to their security posture - it blocks more than 99% of automated account takeover attempts. We deploy MFA across Microsoft 365, line-of-business apps and remote access, with phishing-resistant FIDO2 keys for your highest-risk users.
