OT Site Guardian is a centralized solution designed for security, operations, and safety teams to maintain a "single source of truth" for physical access to critical infrastructure. The application automates the tracking of third-party vendors, contractors, and visitors, ensuring that sensitive site data—such as escort assignments are always accurate and audit-ready. By moving away from fragmented paper logs and manual handoff processes, organizations can streamline their site security workflows and enforce strict operational governance directly within the ServiceNow ecosystem.
