qsa.sh

qsa.sh is a powerful command-line tool designed for developers and security professionals to perform quick, comprehensive external security scans of their own servers. With a single curl command, users can instantly see what the internet perceives about their server—covering open ports, service versions, and known vulnerabilities—delivered directly to their terminal within approximately 30 seconds. Its integration of tools like naabu, nmap, vulners, and nuclei ensures a detailed mapping of potential security gaps without requiring any accounts or data storage. The platform caters to both free, live scans and premium options like the Pro plan, which scans all 65,535 ports asynchronously, and a one-time Deep scan that digs deeper into hidden vulnerabilities via email. Its straightforward approach makes it ideal for sysadmins, security teams, and developers seeking a quick, transparent security overview of their infrastructure.
