The Challenge

Too Much Trust in Local Area Networks.

Industrial networks were designed to be isolated. Today, they are more connected than ever — mixing IT, OT, and decades-old systems, all under pressure to digitalize. Every new connection expands exposure.

Air-Gapped to Connected

Industrial networks are more connected than ever, mixing IT, OT, and decades-old systems under pressure to digitalize.

Conflicting Priorities

Operators keep processes running while IT reduces exposure. Different KPIs, conflicting priorities, and fragile integrations.

Rebuilding Isn't an Option

Tearing down and redesigning networks is slow, costly, and impractical. Facilities can't afford to shut down for weeks.

Regulations Are Piling Up

Sites must demonstrate compliance with NIS2, CMMC, IEC 62443, and sector-specific mandates on networks never designed for it.

The Solution

A Dedicated Security Proxy Per Asset.

TAG delivers Zero-Trust protection for operations without rewiring or downtime. The on-premise appliance uses network overlays and security proxies to shield critical assets with micro-DMZs, enforce identity-based access, and contain lateral movement.

Software-Injected Proxy

No rewiring or changes to the underlay network. Asset cloaking and L3-7 protection deployed through software-defined networking.

On-Premise Appliance

On-premise data processing, local enforcement, better performance. No cloud dependency for security decisions.

Agile Configuration

Agile management layer bringing Zero-Trust capabilities to OT environments with policy-driven automation.

Compliance: Aligned with CMMC, NIST 800-82, NIS2, and DoD OT Zero-Trust guidance.

FAQ

Common Questions About the Access Gate.

agents required. The Access Gate deploys inline and protects assets at the network level — no software on endpoints.

The Trout Access Gate (TAG) is an on-premise appliance that delivers Zero-Trust protection for operational networks. It uses software-defined networking to inject security proxies in front of each OT asset — creating per-asset micro-DMZs without rewiring, downtime, or agents.

The appliance is rack-mounted at the site. It passively learns OT communications and identifies devices, then transparently inserts a policy enforcement proxy in front of each asset through an SDN overlay. The underlying network stays exactly as it is.

No. The Access Gate builds a virtual overlay on top of your existing network using standard IP routing and bidirectional NAT. No VLAN changes, no IP renumbering, no recabling. Legacy PLCs, HMIs, and SCADA systems work without modification.

The Access Gate is aligned with CMMC, NIST 800-82, NIS2, IEC 62443, and DoD OT Zero-Trust guidance (DTM 25-003). It provides the segmentation, identity enforcement, and audit logging required by these frameworks.

Yes. The Access Gate operates at the network level with no agents or software changes on endpoints. It protects assets that cannot be patched, updated, or scanned — including PLCs, HMIs, safety controllers, and equipment that is 10, 20, or 30+ years old.
