Critical Infrastructure Protection
Protect the infrastructurethat keeps society running.
GridGuard transforms critical infrastructure into a continuously aware security environment by combining covert fiber sensing, visual intelligence, edge AI and coordinated operational response. Powered by AIREZ Sense (formerly OpticSense FoRi), Edge AI and the AIREZ GSOC.
- Fiber sensing
- Thermal + PTZ
- Access correlation

A short walkthrough of how the AIREZ Physical Intelligence Layer turns existing utility grid infrastructure into continuous, contextual awareness.
Section 01
Critical infrastructure cannot fail.
Utilities and transportation assets require more than cameras and alarms. A substation fence line, a buried cable trench and a badge reader each tell part of a story — GridGuard monitors all of them continuously and resolves them into one operational picture.
Perimeters
Fence lines, approach roads and open ground monitored without gaps or blind spots.
Sensitive Equipment
Transformers, control houses, pumps and switchgear watched as individual assets.
Access Points
Gates, doors and vehicle entries correlated against authorized activity.
Underground Approaches
Buried fiber detects digging, tunnelling and cable interference before surface signs appear.
Operational Infrastructure
Trackside, intake and trench assets that legacy security never covered.
One Operational Picture
Every sensor class resolved into a single verified situation for the operator.
Section 02
Layered protection architecture.
Four layers, from beneath the ground to the intelligence that reasons over all of them. Each layer sees something the others cannot.
Below grade
Ground Layer
Buried AIREZ Sense (FoRi) fiber provides dig detection, climb detection and vehicle detection along the entire perimeter — covert, passive and immune to visual obstruction.
Section 03
Sensor fusion for critical infrastructure.
GridGuard verifies threats before operators are interrupted. Every step raises confidence, so what reaches the console is an event — not an alarm.
- 01
Fiber Vibration reports a disturbance
AIREZ Sense detects digging, climbing or vehicle movement along the buried perimeter.
- 02
Thermal confirms presence
Heat signature separates a person or vehicle from wildlife and weather.
- 03
Camera identifies the scene
PTZ slews to the reported location and captures visual context.
- 04
Access Control correlates authorization
Badge, gate and barrier state establishes whether the activity is expected.
- 05
Vehicle Movement is analyzed
Approach speed, dwell and direction distinguish routine traffic from intent.
- 06
Edge AI assesses the threat
Cross-sensor agreement produces a scored, classified event.
- 07
Operator is notified
One verified event, with the evidence already assembled.
- 08
Response is recommended
Escalation, dispatch or lockdown, with the operator retaining authority.
Section 04
Edge AI and GSOC intelligence.
Processing happens locally at the site, so decisions do not wait on bandwidth. Only verified events flow onward to the utility SOC and the AIREZ GSOC.
Intrusion Detection
Perimeter breach classified by approach type, not by a single tripped sensor.
Insider-Threat Analysis
Authorized credentials used in unauthorized patterns, times or locations.
Threat Scoring
Every event carries a confidence and severity value operators can triage against.
Alarm Verification
Nuisance alarms resolved locally instead of consuming operator attention.
Lockdown Recommendations
Suggested containment actions scoped to the affected asset.
Event Prioritization
The most consequential event surfaces first across a fleet of sites.
