## PROBLEM / SOLUTION

When production lines stop, waiting days for an OEM technician to travel on-site
causes massive downtime costs, while legacy remote tools introduce severe cyber 
risks. Agilicus AnyX provides an instant, secure alternative:

### The Operational Challenge

❌ **Costly Downtime & Travel Delays:** Complex equipment faults stall production
while waiting for specialized vendor engineers to arrive physically on-site.

❌ **Insecure Shared Passwords:** Legacy VNC and remote desktop tools rely on weak,
shared 8-character passwords with zero individual auditability.

❌ **Full-Subnet Network Over-Exposure:** Traditional VPNs grant broad lateral network
access to external vendors for what should be a single screen diagnostic session.

### The Customer Outcome

✅ **Instant Expert Resolution:** External specialists join live HMI sessions in
a browser within seconds to diagnose issues alongside local operators.

✅ **Strict Read-Only Enforcement:** Set granular view-only permissions so technicians
can inspect telemetry without any risk of unauthorized process changes.

✅ **Identity-Centric Compliance:** Every remote session is authenticated via corporate
Single Sign-On with multi-factor authentication, meeting NIS2 and ISA/IEC 62443 
standards.

## Why Plant Managers Choose Agilicus for ICS

Friction-free, collaborative remote support that satisfies plant floor operators
and corporate IT security teams.

### Concurrent Browser Collaboration

Local operators and remote OEM specialists view the exact same HMI screen simultaneously
in real time without locking out local plant controls.

### Hidden Machine Passwords

Agilicus automatically injects device passwords behind an identity-aware proxy, 
ensuring external vendors never see or handle underlying machine passwords.
