Security company ADT (ADT) , which returned to the public markets on Friday, is facing stiff competition from the likes of Alphabet's (GOOGL) Nest and Amazon (AMZN) .

"There are 14,000 competitors - a lot of people coming into this space," CEO Tim Whall said in an interview with TheStreet. "A lot of them have exited - what we do is hard."

The company is raising roughly $1.5 billion from the IPO and will use the money to pay down debt. ADT made four small acquisitions in 2017 and will continue to look for "target opportunities."
