What is a Zero Day and how to prepare

Zero days threaten to ruin your day every time a new one is discovered. A zero-day is a cybersecurity term for a software vulnerability that is unknown to the public and the software vendor, meaning there are no available patches or fixes to protect against it. "Zero-day" refers to the fact that the software developer has had "zero days" to create a fix, leaving them and their users exposed to attacks from hackers who discover and exploit the flaw. This means there is nothing you can do until a vendor releases an update to fix the discovered issue. Most of the time, vendors will release some guidance about options to keep you safe. When you hear about a zero-day, we usually reach out to the vendor in question for guidance about possible solutions to prevent hackers from exploiting the flaw.
