It can be tempting to hit "snooze" when your phone, browser, or computer alerts you to an available update. 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?

Updates often include:

• Security “patches” for flaws found in the device or application
• Security improvements to fend off new threats
• New security features (like VPNs and password managers)

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.
