The technological shift observed between 2024 and 2025 has effectively dismantled the traditional network-centric security model, replacing it with an identity-centric paradigm where the integrity of user credentials serves as the final line of defense. Identity-based attacks have become the dominant threat vector, with 60% of all incident response cases involved identity as a key attack vector, and a rise of 32% of dentity-based attacks in the first half of 2025 alone.

A simple yet crucial step in securing your business is setting up Multi-Factor Authentication (MFA). Enabling MFA will help ensure the access request came from a known and approved sources, and add another layer of protection to your systems.

What is Multi Factor Authentication?

Multi-Factor Authentication, also known as MFA, enhances security by requiring users to provide more than one form of identification to access their accounts. This typically involves a combination of something they know (like a password) with something they have (such as a code sent to their phone) or something they are (like a fingerprint).

By adding these extra layers of verification, MFA significantly reduces the risk of unauthorized access to sensitive information.

Basic Concept behind MFA

Imagine you work in an office space.

When arriving at the building you swipe your key card to enter, that’s the first authentication factor (”what you have”).

You walk to your desk and login to your workstation, probably with a username and password - that would be your second authentication factor(”what you know”).

Now you need to go to the super-secure room, where you can only enter with a biometric scanner - that would be the third factor (”what you are”).

This example describe the concept of MFA in its most simplified way - the more secure the area is you’re trying to access, the harder you need to prove you are who you claim to be, and in some cases you will need to prove more than once.

Multi-factor authentication is the concept that ensures the identity of the user is confirmed by more than one authentication method (such as Face ID, One-Time Passcode, fingerprint scanner etc.)

How to secure your business with MFA?

The most common way for users to login to their accounts is with a combination of username and password, with an added layer of protection being the user's phone.

Setting up Multi-Factor authentication with a designated application or a OTP is a great way to ensure the login request didn't come from an attacker using the user's information.

Add additional layers of authentication to sensitive network assets to ensure your most precious information is only accessed by authorized users.
