Engineering Resilience for Critical Infrastructure

When Does the Sentinel Step In?

These are the real-world stories of our customers—the moments when technical expertise and rapid response become critical to your operations:

• System Failure & Outages: When your plant process control system stops working during the night and you have tried everything but cannot get it restarted.
• Infrastructure Emergencies: When your telecommunication tower falls over during the night and your system is off the air, or your main power supply is underwater and your enterprise system is offline.
• Critical Transitions: When you need to update your technology to a new version and need to stage the migration to ensure all bases are covered before “going live”.
• Strategic Roadblocks: When you are told your system is unsupported and need trusted advice on the best next step.
• Complex Integrations: When you want to run a project internally but need specific help with multi-vendor integration support you cannot get from a single vendor.
• Operational Fatigue: When your alarms are causing your operators to lose track of the real problems, or when you are simply stuck and need someone to brainstorm with.
