  • Importance of two-factor authentication (2FA) for businesses
  • Duo Security as a leading 2FA provider
  • Acquisition by Cisco for $2.35 billion


In today’s digital age, ensuring the security of online accounts and data is crucial for businesses. 

Two-factor authentication (2FA) effectively protects sensitive information by adding an extra layer of security to the login process. 

Duo Security, a leading provider of 2FA solutions, was acquired by Cisco for a staggering $2.35 billion, highlighting the value of this technology.

What is Two-Factor Authentication (2FA)?

Two-factor authentication (2FA) is a security measure that requires users to provide two different forms of identification when accessing their accounts. 

Typically, this involves something the user knows (like a password) and something the user has (like a verification code sent to their mobile device). 

By adding this second layer of authentication, 2FA makes it much more difficult for unauthorized users to access accounts, even if they have the correct password.

Why Should Founders Care About 2FA?

Founders should prioritize 2FA for their businesses for several reasons:

  • Enhanced security: 2FA significantly reduces the risk of unauthorized access to sensitive information and accounts.
  • Regulatory compliance: Many industries have regulations that require businesses to implement 2FA to protect customer data.
  • Customer trust: Implementing 2FA can help build customer trust, demonstrating a commitment to protecting their information.

Duo Security: A Leading Provider of 2FA Solutions

Duo Security, founded in 2010, quickly became a leader in the 2FA market by offering user-friendly, scalable solutions for businesses of all sizes. 

Their cloud-based platform simplifies deploying and managing 2FA across an organization, making it an attractive choice for founders looking to enhance their security measures.

The value of 2FA: Cisco’s $2.35 Billion acquisition

In 2018, tech giant Cisco recognized the importance of 2FA and acquired Duo Security for a whopping $2.35 billion. 

This acquisition highlights the growing value of 2FA technology and the demand for secure, user-friendly solutions that protect businesses and their customers.


Two-factor authentication is an essential security measure for businesses in the digital age. 

Founders should consider implementing 2FA to protect sensitive information, comply with industry regulations, and build customer trust.
