Resilience testing is the process of evaluating how well digital systems, networks, or applications can withstand and recover from cyberattacks, technical failures, or unexpected disruptions. Through simulated drills or controlled exercises, organizations identify vulnerabilities and assess their ability to maintain essential operations during adverse events. The goal is to ensure systems can quickly recover and continue functioning, minimizing downtime and data loss. Resilience testing helps organizations strengthen their defenses, improve incident response plans, and build trust with users by demonstrating preparedness for potential threats.
