Fortinet FortiGuard OT Security Service 5Y Tier L | OT Security, ELA

Maintain security coverage across operational technology environments with Fortinet FortiGuard OT Security Service Tier L. This 5-year service is built for organizations that need sustained OT protection, not short-term coverage. It supports long-range planning for plants, facilities, and industrial networks where uptime, visibility, and controlled change matter. OT environments demand a different security posture than standard IT. This service is positioned to support that reality with vendor-backed protection designed around industrial operations and the long service horizon required by infrastructure teams. Over five years, it helps simplify renewal cycles, preserve continuity, and keep security services aligned with operational schedules. Choose Tier L when the environment requires a formal service commitment for OT security and the procurement team needs a clear multi-year path. The result is a cleaner ownership model for critical infrastructure, with service continuity that supports planning, budgeting, and risk management across the full term.
