Zero-Trust That Works for Industrial Networks

The Trout Access Gate brings zero-trust principles to environments where traditional identity solutions can't reach — legacy OT, air-gapped networks, and production floors.

Identity-First Access

Every user and device is authenticated before accessing any resource. No exceptions, no implicit trust.

Least Privilege

Users see only what they need. Everything else is cloaked and invisible at the network layer.

Continuous Verification

Sessions are monitored in real-time. Risk changes trigger re-authentication automatically.

Compliance Mapping

Direct mapping to NIST 800-171 AC controls, NIS2 access management, and IEC 62443 requirements.

Complete Audit Trail

Every access attempt, policy decision, and session logged and searchable for compliance evidence.

Overlay Architecture

Deploys on top of your existing network. No rewiring, no cloud dependency, no downtime.

Zero-Trust in Action

Every Connection Authenticated. Every Flow Encrypted.

No Implicit Trust

Flat networks trust everyone inside the perimeter. The Access Gate adds identity-based access control, encryption, and segmentation — without replacing your existing infrastructure. See how it works.

Next: Industrial DMZ

Identity-First Access

Every user and device authenticated before accessing any resource. No exceptions, no implicit trust.

Encrypted Enclaves

Segmented, encrypted zones that enforce least-privilege access across your existing network.

Complete Audit Trail

Every access attempt, policy decision, and session logged for compliance evidence.

We needed zero-trust for our OT network but couldn't install agents on legacy PLCs or route traffic through cloud proxies. The Access Gate gave us identity-based access control without changing a single cable.

Agents required. The Access Gate enforces zero-trust at the network layer without installing software on endpoints, PLCs, or legacy equipment.

A VPN extends your flat network to remote users — once connected, they can reach everything. The Access Gate enforces per-user, per-device, per-resource policies. Users only see what they're authorized to access. Everything else is cloaked at the network layer.

Yes. The Access Gate enforces access control at the network layer, not on the endpoint. Legacy PLCs, HMIs, and SCADA systems are protected without installing agents or modifying their configuration. The overlay sits between users and resources.

The Access Gate integrates with Active Directory, Entra ID, Okta, and any SAML or OIDC-compatible provider. Users authenticate with their existing credentials and MFA. No separate identity system to manage.

Yes. The Access Gate operates entirely on-premise with no cloud dependency. Identity verification, policy enforcement, and audit logging all happen locally. It's designed for classified, air-gapped, and regulated environments.

You can add new assets, plants, or sites without re-architecting. The overlay is software-defined — adding a new enclave or extending policies to a new location is a configuration change, not a network redesign.
