The bigger your name, the bigger the cyber target on your back (no pun intended for the number one breach on our list). Retailers face growing cybersecurity risks.

Cybersecurity is a constant journey, always full of fresh challenges. New threats keep popping up. Endpoint-only solutions are ineffective. And the cybersecurity skills shortage makes it difficult to recruit and retain top talent — especially with the increasing salaries required to be competitive.
