Hindsight is 20/20. Almost five years ago, Equifax announced that it had been breached and that the sensitive data of over 148 million people, about 56% of Americans — including names, home addresses, social security numbers, driver’s license information, etc. — had been compromised. There were an additional 209,000 credit card records leaked as well. While there have been larger-scale attacks since then, Equifax was unprecedented in its time. Instead of taking a critical approach, the Equifax breach has taught and will continue to teach, essential cybersecurity lessons that can help business leaders protect their customers even better moving forward.
