Threat Protection
Threat protection encompasses the strategies, technologies, and processes organizations implement to defend against cybersecurity threats. It includes proactive measures to prevent attacks, real-time detection of threats, and responsive actions to mitigate damage from security incidents.
What is Threat Protection?
Threat protection refers to the comprehensive set of security measures, technologies, and practices designed to defend systems, networks, data, and users from cyber threats. It goes beyond simple detection to include prevention, response, and recovery capabilities, creating multiple layers of defense against evolving attack methods. Effective threat protection requires a proactive, multi-faceted approach that adapts to new threats while maintaining usability and performance.
