Connect your plant to the cloud without opening a single port
vNode uses reverse connectivity, outbound-only connections, encrypted end to end with TLS 1.3. So there’s nothing new for IT to approve, and nothing new exposed to attack.
- No credit card
- No coding
- Live and running in minutes

THE PROBLEM
The firewall isn't the problem. It's the excuse.
Every time you propose connecting the plant to IT or the cloud, the project stalls in the same place, and it’s never the first time.
- Request denied. IT rejects the port-opening request on policy grounds, no timeline for reconsideration.
- Months of review. A week of integration work turns into a quarter of committees and sign-offs.
- Data stays locked. Cloud, BI, and AI initiatives wait on data that never leaves the plant floor.

↓ Firewall · 0 inbound ↓
Cloud / IT
Azure · AWS · SQL
Traffic only ever flows outbound. Nothing for IT to approve.
THE SOLUTION
Four layers of security. Zero ports opened.
Reverse connection, TLS 1.3 encryption, certificate or LDAP authentication, and data-diode isolation. Four independent layers, not one single barrier.
Reverse Connection
vNode connects outbound only — the same way your browser reaches a website. No inbound rule to open, no new attack surface, nothing for IT to sign off on.
TLS 1.3 encryption
Every connection encrypted end to end, with AEAD and ECDH key exchange.
Certificate + LDAP authentication
Digital certificates, tag-based permissions, or straight into Active Directory.
Data Diode ready
For zones where outbound-only still isn't strict enough, vNode supports data diode connections — hardware-enforced one-way flow.
USE CASE · SECURE MULTI-SITE ARCHITECTURE
Moving data between plants? Same rule applies.
Run vNode in the DMZ and exchange data site-to-site. Still without opening a single inbound port.

HOW IT WORKS
A software gateway inside your OT network. It sends data out — so IT never has to let anything in.
vNode is not a firewall change, a VPN, or a new appliance for IT to secure. It’s software you install on a PC or industrial box already inside the plant network. It reads your PLC and SCADA data over OPC UA, Modbus, DNP3, or Siemens — then pushes it out through a connection your firewall already allows outbound. No exception request. No committee.
1
Install
Deploy vNode on Windows, Linux, or ARM — on hardware already inside your OT network. No new appliance, no change to network topology.
2
Connect
vNode opens an outbound-only, TLS 1.3-encrypted connection — the same kind of traffic your firewall already allows. Nothing for IT to flag, because nothing new is exposed.
3
Flow
Your OT data lands where your team decided — Azure, AWS, Google Cloud, SQL, MongoDB, MQTT, REST API — without ever opening a path back into the plant.
