Threat detection and response (TDR) refers to the process of identifying and neutralizing malicious threats present within your IT infrastructure. It involves proactive monitoring, analysis, and action to mitigate risks and protect against unauthorized access, malicious activities, and data breaches before they cause any potential harm to your organization's network. Threat detection uses automatic security tools like IDSs, IPSs, firewalls, endpoint protection solutions, and SIEM solutions to achieve this.
Threat detection is crucial to detect and respond to threats as soon as they occur in order to thwart malware, ransomware, and other cyberattacks that could damage key data and disrupt corporate operations.
