It can be tempting to hit "snooze" on that update alert on your phone, browser, or computer. But letting your device or software update right away could mean the difference between having a smoothly running system and one at risk from ransomware, hackers, or viruses.

Why are timely updates so important?

Cybercriminals are always looking for weaknesses in software and device security that allow them to steal information. This is one of the reasons why devices and software receive security “patches” (quick fixes) on a regular basis. Software developers and cybercriminals are in a constant game of cat and mouse. 

Sometimes hackers will find and exploit a weakness before security experts have a chance to release a patch. When this happens, it’s called a zero-day vulnerability, and they put your device and your data at high risk. 

The only way to combat a zero-day vulnerability is to update your device when a patch is pushed through. This means updating your devices as soon as updates are available. By changing your settings to allow auto-updates you’ll never have to wonder if your device is up-to-date.
