## PROBLEM / SOLUTION

Supporting remote PLCnext installations traditionally forces organisations to choose
between costly site visits, risky port forwarding, or cumbersome VPN networks. Agilicus
AnyX delivers a direct, identity-secured alternative:

### The Operational Challenge

❌ **Costly Site Dispatches:** Minor logic edits, routine diagnostics, or commissioning
tweaks require hours of travel when remote access is absent or unreliable.

❌ **Hardware & Subnet Sprawl:** Traditional gateways add capital costs, panel space,
and failure points, while legacy VPNs break when managing overlapping IP subnets
across multiple client sites.

❌ **Broad Network Exposure:** Opening inbound ports or granting full-subnet VPN
access exposes critical plant controllers to lateral traversal and unauthorized 
discovery.

### The Customer Outcome

✅ **Instant Remote Resolution:** Engineers connect directly via native PLCnext 
Engineer in seconds to resolve issues immediately, dramatically reducing downtime.

✅ **Zero-Footprint Architecture:** The connector installs natively on the Linux-
based PLCnext controller or on any host in the SCADA network, eliminating auxiliary
gateway hardware.

✅ **Isolated, Identity-Centric Access:** Every session is authenticated via corporate
Single Sign-On and multi-factor authentication, enforcing precise, audited access
to only the designated controller.

## Why Engineers Choose Agilicus for PLCnext

Secure, responsive, and hardware-native remote access built for modern automation
environments.
