What is a Zero-Day?
A zero-day is a major danger for every company. In this blog we tell you more about what a zero-day is and ways to prevent it.
Zero-Day is a form of vulnerability used by hackers and cybercriminals to gain access to company or personal data. It's a term often used in the world of cybersecurity, where it is a dangerous and common phenomenon. The term refers to the moment the vulnerability is discovered, usually before the company that owns the vulnerability finds out. At this point, no solution or "patch" is available yet, allowing cybercriminals to exploit it to gain access to, for example, sensitive data.
Characteristics of a Zero-day
The key characteristic of a Zero-Day is that it is a vulnerability the organization doesn't yet know about. Because they're not aware of the problem, no measures can be taken to fix the vulnerability. A Zero-Day vulnerability therefore gives cybercriminals an enormous amount of time to operate freely within an organization. They can use the vulnerability to gain access to company or personal data, creating an enormous threat.
What matters with a zero-day vulnerability
It's important for companies to continuously search for Zero-Day vulnerabilities in their software and systems. There are various ways a company can gain insight into a Zero-day vulnerability. One of the most effective methods is carrying out a pentest. Carrying out a pentest is done by an ethical hacker. During a penetration test, they search for vulnerabilities in your software and systems. Because continuity in searching for these vulnerabilities is so important, we offer Hacking as a Service subscriptions. With these, we offer the option to pentest on a monthly basis. In addition, multiple advanced security scanners scan your digital environment on a daily basis.
