It powers everything, from laptops and smartphones to smart TVs, doorbells, cameras, and even appliances like refrigerators.

Many of these devices are not built with strong security in mind, making them potential entry points for hackers. The good news? Wit

In this blog, ESG IT Consulting breaks down the differences, similarities, cost implications, and current marke
