Industrial connectivity creates value. It also increases risk.

As machines, controls, and service teams become more connected, industrial organizations need a better way to govern access, protect OT networks, and maintain visibility across connected assets.

Traditional remote access, unmanaged VPNs, and one-off connections can create unnecessary exposure. A stronger OT security model gives teams a repeatable way to:

  • Verify users before machine access
  • Control permissions by role, site, customer, or equipment
  • Segment machine networks and reduce broad plant exposure
  • Avoid open inbound firewall ports where possible
  • Track sessions, activity, and access history
  • Support IT security requirements without slowing service teams

A security-first model for connected machines

Step 1: Connect Securely

Use controlled, outbound-only connectivity designed for industrial environments.

Step 2: Govern Access

Apply identity, permissions, approvals, and session controls.

Step 3: Segment Networks

Separate facility access from machine-level access and limit unnecessary exposure.

Step 4: Monitor Activity

Maintain visibility into access, sessions, and service history.

Step 5: Scale With Control

Apply a repeatable model across machines, sites, customers, and service teams.

Ready to strengthen OT access control?
Best started with a security and access review

ei3 OT access pilot

An OT cybersecurity pilot can help validate:

  • Which machines, sites, or customer environments need better access control
  • How users, roles, and permissions should be structured
  • Where existing remote access methods create exposure
  • Which security requirements matter most to IT and OT stakeholders
  • How to scale secure access across a broader machine fleet

Frequently asked questions

What is zero-trust OT security?

 Zero-trust OT security applies stronger verification, access control, segmentation, and visibility to industrial environments so users only access the machines, systems, or networks they are authorized to use. 

Is ei3 a replacement for a traditional VPN?

 ei3 provides a secure industrial remote access model with centralized access control, machine-level segmentation, and session visibility. It can help teams reduce reliance on broad or unmanaged VPN access. 

Can ei3 support both IT and OT requirements?

Yes. ei3 is designed to support IT security expectations while giving OT and service teams practical ways to access, diagnose, and support machines.

Does secure access slow down service teams?

 It should not. The goal is to give service teams controlled access to the right machines while maintaining governance, visibility, and security. 

What does a pilot usually include?

A pilot typically focuses on a defined set of machines, customer environments, or service use cases to validate connectivity, security, workflows, and rollout requirements.
