Flan Scan

Flan Scan is a lightweight open-source network vulnerability scanner designed to make it easy to detect exposed services, open ports, and associated vulnerabilities across IP ranges or network segments as part of security audit and compliance workflows. It is essentially a thin wrapper around the widely-used Nmap scanner, augmenting it with scripts and tooling that transform raw Nmap output into vulnerability-focused reports that map detected services to known CVEs, making results more actionable for administrators and auditors. Flan Scan supports automated builds via Docker and can be deployed in containers or Kubernetes clusters, allowing organizations to run scans consistently across distributed environments. Users provide target IPs or CIDR ranges, and the tool orchestrates Nmap scans with version detection and the “vulners” NSE script, collects results, and outputs aggregated reports in formats like LaTeX, markdown, or JSON.
