Automated patching is a cybersecurity mechanism that systematically applies software updates, security fixes, and vulnerability patches across an organization's IT infrastructure without requiring manual intervention for each deployment. This process leverages specialized tools and orchestration platforms to monitor for new patch releases and automatically distribute them to operating systems, applications, and firmware based on predefined policies and schedules. Within Security Automation and DevSecOps frameworks, automated patching integrates security proactively into development and operational workflows, significantly reducing the window of opportunity for attackers to exploit known vulnerabilities.

The primary purpose of automated patching is to strengthen an organization's security posture by ensuring timely remediation of exposures, minimizing the attack surface, and mitigating risks from cyber threats. Beyond its preventative security functions, this automated process enhances operational efficiency by freeing IT and security personnel from repetitive tasks, ensuring consistent application of updates, and reducing human error. Automated patching is also critical for maintaining compliance with regulatory frameworks and industry standards, making it an indispensable component of a resilient defense strategy against evolving threats.
