Zero day refers to security vulnerabilities that are discovered in software when teams had “zero days” to work on an update or a patch to remediate the issue and, hence, are already at risk. If a malicious attacker can identify a key software vulnerability, they can exploit the vulnerability, allowing them to gain access to your systems.

Five-nines availability: The ultimate benchmark of system availability. Instead, to speed up response times, applications are now processing most data at the network’s perimeter, closest to the data’s origin. Ideally, teams need the ability to anticipate problems and fix conditions before an issue develops.
