What Is 0-DAY?
Zero Day refers to a software flaw that hackers discover before anyone else, even the developer. These vulnerabilities are used in zero-day attacks, where there’s no patch, no warning, and no time to respond.
That’s why Zero Day exists: to deliver real-time threat detection, incident response services, and exploit prevention techniques built specifically for Australian businesses.
Whether you need cybersecurity services in Melbourne or help with secure coding practices, we’re your first defence against the unknown.
