# Overview

The Cisco Firewall Hardening Tool automates the generation of CIS-compliant security configurations for Cisco ASA and FTD (Firewall Threat Defense) devices. This tool eliminates manual hardening workflows by producing production-ready configurations based on industry security standards and best practices.

Organizations managing Cisco firewall infrastructure benefit from rapid, consistent security posture improvements. The tool supports flexible hardening options, enabling security teams to customize configurations to their specific compliance requirements and network architecture. It is ideal for enterprise security teams, managed security service providers (MSSPs), and DevSecOps professionals who need to deploy hardened firewall configurations at scale.

By automating compliance-driven configuration generation, the tool reduces human error, accelerates deployment timelines, and ensures adherence to CIS benchmarks across your firewall estate.
