There is a terrifying metric in cybersecurity known as “dwell time.” It is the amount of time an attacker remains undetected inside a network before they are found. According to recent industry reports, the average dwell time can range from weeks to months.<\/p>\n

This leads to an uncomfortable question that every IT professional must ask themselves: What if the breach has already happened?<\/p>\n

If your servers are running smoothly and your firewall isn’t flashing red, it doesn’t necessarily mean you are safe. It might just mean you aren’t looking in the right places. This is the core philosophy of “Threat Hunting”, and it is where Wazuh, the open-source SIEM and XDR platform, shines.<\/p>\n
