Whereas a less-known firm could supply extra bells and whistles at a greater value, a well-established supplier that’s breached is extra more likely to care about its popularity and do issues to assist customers, mentioned Kevin Roundy, senior technical director at cybersecurity firm Gen Digital.

Additionally remember to preserve the machine and the app up-to-date with safety fixes.

Whereas nothing is foolproof, the aim is to be as safe as attainable. “If anyone tries to revenue from our private info, we simply make their lives tougher so it is not that straightforward to hack us,” Demeter mentioned.
