Multi-Factor Authentication (MFA) has become an indispensable security measure in today’s cyber threat landscape, especially for services like Microsoft 365 (M365) and Virtual Private Networks (VPNs). By requiring users to provide multiple forms of identification, MFA significantly enhances the security of these publicly accessible IT services and drastically reduces risk.
Why MFA Matters for M365
M365, a suite of cloud-based productivity applications, houses sensitive data such as emails, documents, and calendars. Implementing MFA adds a crucial layer of protection against unauthorized access. With MFA, if an attacker obtains a user’s password, they would not be able to log in without also providing a second factor of authentication, such as a code or prompt sent to the user’s phone or a biometric scan.
Key Benefits of MFA for M365
- Prevents unauthorized access: MFA makes it significantly harder for hackers to gain access to user accounts, even if they have a password, preventing Business Email Compromise (BEC).
- Protects sensitive data: By safeguarding user accounts, MFA helps to protect sensitive data stored in M365 applications.
- Reduces the risk of phishing attacks: MFA can help to mitigate the risk of phishing attacks, where attackers attempt to trick users into revealing their login credentials.
It is shocking to me that more people are not calling us begging us to enable MFA, instead of the other way around. Yes, it is slightly less convenient than not having MFA, but that inconvenient factor is a distant memory the first time your email account is highjacked and your company’s data and reputation are at risk. The first thing that typically happens is the Threat Actor will email every one of your contacts, helping to propagate the threat.”

Key Benefits of MFA for VPNs
Prevents unauthorized access
MFA ensures only authorized users can connect to the VPN.
Protects sensitive data
By preventing unauthorized access, MFA helps to protect sensitive data transmitted over the VPN.
Reduces the risk of credential stuffing attacks
MFA can help to mitigate the risk of credential stuffing attacks, where attackers use stolen credentials to try to gain access to multiple accounts.
Implementing MFA: Best Practices
To maximize the benefits of MFA, it’s essential to implement it correctly. Here are some best practices:
- Choose strong authentication methods: Select MFA methods that are difficult to compromise, such as phishing-resistant codes sent to a mobile device or biometric authentication.
- Educate users: Ensure that users understand the importance of MFA and how to use it correctly.
- Enforce MFA for all users: Require all users to enable MFA, regardless of their role or location.
- Regularly review and update MFA settings: As new threats emerge, it’s important to review and update MFA settings to ensure they remain effective.
- Ensure your cyber liability insurer is updated: Many cyber insurance policy underwriters are now providing credits against your policy premiums, presenting an opportunity for cost-savings.
A Shield Against Cyber Threats
By implementing MFA for M365 and other publicly accessible services, organizations can significantly enhance their security posture and protect their valuable data against threats such as extortion, wire transfer fraud, and ransomware.
