CalCom Hardening Suite (CHS) for SQL Server is a server hardening tool designed to automate the secure configuration of Microsoft SQL Server environments. It addresses challenges associated with manual hardening processes, including configuration drift, environment variability, and compliance maintenance. The product operates through three distinct modes: - **Learning Mode:** Discovers SQL Server internal components, records existing configuration settings, analyzes systems to identify hardening exceptions, and simulates the impact of policies before they are applied to production environments. - **Enforcement Mode:** Applies granular hardening policies across multiple SQL Server versions from a centralized dashboard, limits enforcement authorization to designated personnel, and supports hybrid cloud environments with one-click rollback capability. - **Monitoring Mode:** Provides real-time access control protection, detects unauthorized configuration changes, conducts automatic gap analysis at scheduled intervals, and enforces hardened values to prevent configuration drift. CHS for SQL Server supports CIS Benchmark-based policies and is designed to maintain compliance with government and industry regulations without requiring system downtime during the hardening process. It allows organizations to manage multiple SQL Server versions and environments (development, staging, production) from a single interface, with rollback functionality to safely undo enforcement actions when needed.
