## PROBLEM / SOLUTION

When complex manufacturing systems encounter errors, getting diagnostics to remote
specialists traditionally creates severe security risks and delays. Agilicus AnyX
provides a modern, isolated alternative:

### The Operational Challenge

❌ **Risky USB Flash Drives:** Manually copying log files onto external USB drives
introduces significant malware and ransomware risks to air-gapped production cells.

❌ **Unencrypted Email Attachments:** Emailing sensitive operational logs exposes
proprietary plant data, recipe information, and internal network addressing.

❌ **Full-Tunnel VPN Over-Exposure:** Granting broad network VPN access to external
contractors just to inspect a log file creates massive lateral movement risk.

### The Customer Outcome

✅ **Direct Browser-Based Review:** Integrators view and download only the required
log files instantly in a secure web portal without installing client software.

✅ **Strict Read-Only Isolation:** Restrict access strictly to designated log folders,
completely preventing unauthorized file modifications or deletions.

✅ **Ephemeral, Audited Access:** Access is authenticated via corporate Single Sign-
On and automatically revoked the moment the support ticket is resolved.

## Why Manufacturers Choose Agilicus for Diagnostics

Frictionless, air-gap-friendly log sharing that satisfies plant managers and IT 
security auditors alike.

### Granular Directory Scoping

Isolate external access strictly to specific diagnostic directories on the machine,
keeping adjacent system files and network shares invisible.

### Software-Free Browser Access

External contractors access diagnostic files directly through a standard web browser
using their own corporate credentials with multi-factor authentication.
