What is zero-day vulnerability?

The internet has become a dangerous place for digital data. Even if you have the right security measures for your business, it doesn’t guarantee complete protection. Organizations need to stay alert as their defenses can be breached anytime. Apart from phishing, cross-site scripting, and various other popularly known cyberattacks, enterprises are also fighting the carefully orchestrated zero-day vulnerability attacks.

A zero-day (also known as 0-day) vulnerability is a software-based security flaw unknown and unaddressed by its vendor, making it difficult to patch.
