Multi-factor authentication (MFA) is an IT authentication technique that requires a user to present at least two factors that prove their identity.
Why MFA Isn’t Optional Anymore: Protecting Your Business in 2025
As the digital landscape grows more complex, so do the threats. In 2025, businesses face constant cybersecurity risks like credential theft to ransomware attacks. That’s why Multi-Factor Authentication (MFA) has become vital for cybersecurity. It’s no longer just a best practice, but a baseline requirement.
At Sierra Experts, setup for MFA is fast. It’s easy. And it could save your business from major damage.
Understanding MFA: More Than Just a Password
Any type of 2 Factor Authentication is better than a password alone. As you add more layers of verification, an account becomes more secure. When more than two factors are used, it can be called multi-factor authentication, or MFA.
MFA requires users to verify their identity using two or more factors:
• Something you have. A cellphone, keycard, or USB could all verify your identity.
• Something unique to you. Fingerprints, iris scans, or some other biometric data prove that you are who you say you are.
Even if a hacker has your password, they’ll still hit a wall without the second piece of proof. Given these risks, choosing the right MFA method is crucial to your business security.
Why Traditional Logins Fall Short
Despite their widespread use, passwords alone are no longer secure, and let’s be honest; some of us use the same password for more than one account. Often reused or easily guessed passwords can allow hackers to slip in and steal anything they want.
Once a password is stolen, an attacker can move freely through your system unless another layer of protection is in place.
This is where MFA becomes critical. According to Microsoft, enabling MFA can prevent 99.9% of account compromise attacks. In other words, it adds a barrier that most cybercriminals can’t get past.
Choosing the Right MFA Method
Fortunately, Sierra Experts can help. Depending on your business needs, we will take you through the setup, where you can choose from several effective methods:
• Authenticator Apps (e.g., Microsoft or Google Authenticator): A quick and secure option for most users.
• Biometrics: Fingerprint or facial recognition ensures only the right person gets access.
• Hardware Tokens: USB keys or fobs offer physical security for high-sensitivity environments.
• Text Message Codes: While better than nothing, this method is more vulnerable to interception.
Each method varies in convenience and security, but all are far more effective than relying on passwords alone.
DUO for MFA
At Sierra Experts, one of the trusted tools we use is Duo Security, a leading MFA platform that provides strong protection for our clients and data.
Duo works by requiring a second verification step with a mobile push notification or passcode, before granting access to systems or applications. Duo integrates into your infrastructure and is easy to grasp for new MFA users to operate.
Implementing MFA Doesn’t Have to Be Complicated
When managed by a trusted MSP like Sierra Experts, your MFA setup is continuously monitored, updated, and optimized to stay ahead of any threats. In an ideal, security-centric world, multi-factor authentication should be the standard.
