With organisations enforcing work-from-home protocols, Arora realised the need for cybersecurity solutions quite early on in the pandemic. And with major IT companies on the back foot, TAC tapped into the huge demand and notched a 300% surge in growth. Arora, also the author of three books and an ethical hacker, started TAC in 2013, when he was 19 and with ₹75,000 as seed capital. Today, its clients include the Central Bureau of Investigation (CBI), Punjab Police, and Reliance Industries, among others. Not bad for someone who struggled through school.
