Industrial Automation · Secure Remote Access
Your PLC. In front of you. From anywhere.
CatchPLC creates a secure digital tunnel to the PLC on your plant floor — connect, program, and troubleshoot from your desk, your home, or the other side of the country. No static IP. No port forwarding. No site visit.
ANYWHERE ENCRYPTED
TUNNEL PLC
ON-SITE
The Problem
Every change means a drive to site.
No public address
Firewalls and NAT mean your PLC's PC has no static IP — there's no address to connect to from outside.
Risky workarounds
Port forwarding and exposed VPNs open security holes just to get occasional remote access.
Vendor lock-in & downtime
Even a small configuration tweak means a drive to site and lost production hours.
Multiple OEM tools
Every PLC brand's programming software expects a local connection — none of them are built for remote-first work.
How CatchPLC Works
A tunnel that dials out, not in.
Conceptual overview — exact authentication and encryption details are confirmed during onboarding.
01
Install the on-site agent
A lightweight agent runs on the PC already connected to the PLC.
02
It dials out
The agent opens an outbound, encrypted tunnel to the CatchPLC relay — no inbound ports, nothing to open on your firewall.
03
You connect remotely
Reach the PLC as if you were standing next to it — using its native programming and diagnostic tools.
04
Access is controlled
Authenticated users and session logging keep every connection accountable.
What You Get
Reach the PLC like you're standing next to it.
Remote programming & diagnostics
Use the PLC's own native tools — program, debug, and troubleshoot exactly as you would on site.
Firewall-friendly, outbound-only
No static IP, no port forwarding, no inbound exposure on your network.
Encrypted, authenticated sessions
Every connection is encrypted and tied to an authenticated user, with session logging.
