CalCom Hardening Suite (CHS) by CalCom is a server hardening automation solution designed to enhance security, reduce operational costs, and ensure a constantly monitored, resilient server environment. CHS automates server hardening without breaking server applications or operations. It utilizes automated analysis and streamlined policy implementation to boost system security and operational efficiency. CHS's learning mode simplifies system hardening by identifying and logging exceptions, applying policies to server groups, and resolving conflicts in the production environment. It helps achieve compliance with standards such as PCI DSS, HIPAA, NIST, ISO 27001, and FFIEC. CHS performs automated impact analysis on production systems, ensuring zero server outages and no engineer time spent on testing. It enables a Sys Admin to learn one server and apply the policy to identical servers, aiding in managing conflicts with Group Policy Objects (GPO). CHS locks down servers with CIS security benchmarks cost-effectively and without disrupting production. It reduces the need for extensive policy testing and minimizes outages from hardening. CHS offers a dynamic dashboard for analyzing compliance and risk posture, aiding IT management in prioritizing server hardening tasks and managing unhardened objects marked as exceptions to meet auditor requirements.
