Zero-Trust Access
- Verify users before machine access
- Apply permissions by role, site, or equipment
- Track sessions with full audit visibility
Industrial Machine Connectivity
Securely connect to PLCs and industrial machines
Enable remote access to PLCs, HMIs, IPCs, and machine networks using the ei3 connection model that fits your equipment, customer sites, and installed base.
Trusted to power secure connected machine programs across global OEMs
Start With Secure Access. Build Toward Scalable Connectivity.
Remote access to PLCs and machines should be secure, consistent, and practical—not a one-off fix. ei3 provides scalable, secure remote access to industrial equipment to support service, modernization, and field troubleshooting.
Connect to the right machine
Access PLCs, HMIs, IPCs, and machine networks through a controlled remote access model.
Support mixed environments
Use a connection approach that can fit new builds, existing machines, and varied customer site requirements.
Reduce VPN and access sprawl
Replace inconsistent remote access methods with a more standardized model.
Support IT and OT expectations
Maintain stronger control over users, sessions, permissions, and machine network exposure.

A standardized model for secure remote access
Two-Tier Architecture
- Separate facility access from machine-level access
- Segment machines, cells, and networks
- Control access without broad plant exposure
Outbound-Only Connectivity
- No inbound firewall ports required
- Encrypted communication through ei3’s secure network
- Designed for IT approval and OT management
Remote Access is the First Step
Step 1: Connect
Establish secure access to machines and controls.
Step 2: Diagnose
Give technical teams a better way to support issues remotely.
Step 3: Support
Help customers faster without always sending someone onsite.
Step 4: Scale
Apply a repeatable model across more machines and sites.
Start where you are. Scale as you want.
Not every machine, site, or customer environment is the same. ei3 supports multiple secure connection models so teams can choose the right deployment path without forcing every machine into the same setup.
Hardware Gateway
Use a dedicated industrial gateway to connect machines and machine networks where a physical edge device is the best fit.
Best for
- New equipment programs
- Standardized machine builds
- Customer sites that need a dedicated industrial access point
Virtual
Gateway
Deploy secure machine connectivity through a virtualized or container-based model on compatible industrial edge hardware.
Best for
- Modern edge architectures
- Flexible deployments
- Environments where adding separate hardware is not ideal
Installed Base Upgrade
Bring existing machines or legacy remote access setups into a more secure, centralized access model over time.
Best for
- Mixed fleets
- Phased modernization
- OEMs supporting machines already in the field
Compatibility Across Your Machine Environment
Whether your team needs access to PLCs, HMIs, IPCs, drives, sensors, or machine networks, ei3 can help confirm the right connection model for your environment.
PLCs & Controllers
Support secure connectivity across widely deployed PLCs, controllers, and industrial automation platforms.
HMIs & Industrial PCs
Connect to operator interfaces, industrial PCs, edge devices, and machine-level systems used for visibility and troubleshooting.
Protocols & Interfaces
Support standard protocols like OPC UA, Modbus TCP, and EtherNet/IP, along with vendor-specific interfaces such as RSLinx, TwinCAT, and MELSEC.
Legacy & Mixed Fleets
Support older equipment, brand-specific interfaces, and phased modernization programs without forcing every machine into one deployment model.

Frequently asked questions
Can ei³ provide remote access to PLCs and industrial machines?
Yes. ei3 enables secure remote access to PLCs, HMIs, IPCs, and machine networks through a controlled industrial connection model. The right deployment approach depends on the machine, customer site, equipment environment, and access requirements.
Does ei³ support remote access without opening inbound firewall ports?
Yes. ei³ is designed around outbound-only connectivity, helping reduce the need for open inbound firewall ports while maintaining controlled remote access to machines and machine networks. =
How does ei³ connect to machines remotely?
ei³ supports multiple connection models, including dedicated industrial gateways, virtual gateway options, and deployment paths for existing machines or installed base modernization. This allows teams to choose the model that best fits their equipment and customer environment.
How does ei³ help protect customer networks?
ei³ helps limit broad network exposure through secure outbound connectivity, machine-level segmentation, controlled user access, and session visibility. This gives teams a more governed way to access machines remotely.
Is ei³ a VPN?
No. ei³ is not a traditional VPN. It provides a secure industrial remote access model with centralized access control, session visibility, and machine-level segmentation, helping teams avoid broad or unmanaged access into customer or plant networks.
What types of equipment can ei³ support?
ei³ can support remote access to a range of industrial equipment, including PLCs, HMIs, IPCs, machine networks, controllers, and related automation devices. Compatibility depends on the specific equipment, protocols, network setup, and deployment model.
Can ei³ connect to machines that are already installed in the field?
Yes. ei³ can support both new machines and existing installed base environments. Many teams start by validating a specific machine, site, or customer environment before expanding to additional equipment.
