Multi-factor authentication (MFA) has become an essential cybersecurity tool for businesses of all sizes. Implementing MFA provides multiple layers of protection that can significantly reduce the risk of costly data breaches. But what exactly is MFA and what key benefits does it offer for SMEs?

What is MFA?

MFA requires users to present two or more verification factors when logging into a device, application or network. The factors fall into three main categories:

  • Knowledge factors: Something the user knows, like a password or PIN code
  • Possession factors: Something the user has, like an authenticator app on a mobile device
  • Inherence factors: Something the user is, like a fingerprint, facial or voice scan

By requiring two or more of these factors, MFA prevents unauthorised access even if the password is known. Whenever a login attempt occurs, the user will have to verify their identity via an additional factor like a fingerprint scan or one-time passcode. This added layer of security is an effective tool for blocking cybercriminals.

Benefits of Implementing MFA
  1. Preventing Data Breaches - Added login factors prevent attackers from infiltrating networks and applications even if they have user credentials. This safeguards against data breaches that can lead to loss of customer data, intellectual property, and other sensitive information.
  2. Protect Customer Data and Trust - For businesses that store customer data like names, addresses and payment card details, MFA is essential for upholding data protection duties and avoiding substantial breach fines. By implementing MFA, companies demonstrate a clear commitment to cybersecurity, helping build customer trust and loyalty.
  3. Securing Remote Access - The rise in remote work has increased the risks associated with employees accessing networks and apps from outside the office. MFA adds a vital layer of protection for any external logins by restricting access to verified users.
  4. Meet Compliance Requirements - Some industry regulations such as Cyber Essentials require MFA for network and system access to improve cybersecurity. Implementing MFA helps demonstrate compliance with key data security standards.
Getting Started With MFA

For most small businesses, the most practical MFA solutions include mobile authenticator apps, SMS/text message codes, security keys and biometrics like fingerprint authentication.

Many of our customers use authenticator apps to securely access business email accounts. This is a simple and effective form of MFA for email protection.
