The summer of 2021 was hot, but the air conditioning in my flat was malfunctioning, leading me to spend more time at a local café in Berlin. One rainy afternoon, as I hunched over my laptop, a conversation unfolded between two tech-savvy students. They were animatedly discussing a recent data breach that had upended a well-known retail chain, leaving customers vulnerable and profits plummeting. Their impassioned debate about the consequences of such negligence led me to a startling realization: in today's hyper-connected environment, cyber security is no longer a luxury, but a necessity. It’s a fortress against an ever-growing tide of digital threats.
