OTIFYD OT Asset Hardening is a professional services offering focused on reducing the attack surface of Operational Technology (OT) environments. The service applies system hardening principles — removing unnecessary programs, user accounts, functionality, connectivity, ports, and permissions — to minimize the opportunities for attackers and malware to gain a foothold in OT environments. The service covers six distinct hardening domains: - Application hardening - Operating System (OS) hardening - Server hardening - Endpoint hardening - Database hardening - Network hardening OTIFYD begins with a high-level vulnerability assessment and analysis of the current security posture using industry-recognized tooling and best practices. From this, a remediation roadmap is established, including patching and risk reduction recommendations. The service accounts for the operational constraints unique to OT environments, where applying IT-standard policies may cause reliability or availability issues. The service is applicable across the full OT asset lifecycle — from initial installation and configuration through maintenance, support, and end-of-life decommissioning. It also addresses regulatory compliance requirements and cyber insurance demands. Proactive consultation is available for OT environments still in planning or project phases.
