Trout Access Gate Features

You cannot protect or comply with what you can’t see

NIS2 requires organizations to identify, manage, and secure the systems that support essential and important services.

In on-premise and industrial environments, this is only possible with continuous, network-level visibility.

Without real-time asset visibility, both security controls and compliance assessments are built on assumptions.

NIS2 makes cybersecurity a board-level responsibility, with direct accountability for leadership.

Trout provides a simple, on-premise way to deliver this visibility, control, and evidence without agents or disruption.

Identify systems supporting essential or important services
Assess cybersecurity risks based on real assets, not assumptions
Understand communication paths and dependencies
Detect asset and exposure changes over time
Provide evidence of asset awareness and control

Trout Access Gate capabilities

Trout Access Gate Features

On-premise asset visibility built for NIS2

On-premise asset visibility built for NIS2

Trout Access Gate provides agentless, on-premise visibility into IT and OT environments by observing live network traffic.

There are no agents to deploy, no scans to run, and no changes required on legacy devices.

Once installed, IT teams gain a real-time view of connected assets, access paths, and activity ; and the evidence needed to support NIS2 compliance.

Passive network visibility

Observes live traffic without scanning, probes, or agents. Safe for OT and legacy systems.

Real-time asset inventory

Maintains a continuously updated inventory based on actual network activity.

Asset role and zone identification

Identifies assets by function and location across IT, OT, and DMZ zones.

Communication flow mapping

Shows real communication paths, protocols, and dependencies between systems.

Continuous change detection

Detects new assets, behavior changes, and new access paths as they occur.

Operational Impact

Trout Business ROI
Trout Business ROI

NIS2 raises accountability and reporting requirements, while many teams still rely on fragmented tools and manual workflows.

Trout replaces spreadsheets and point tools with a single on-premise control point that delivers continuous visibility and audit evidence.

For IT teams, this means:

  • Fewer blind spots

  • Faster incident scoping

  • Less time spent assembling audit data

  • A repeatable, defensible compliance posture

How Trout Access Gate Secures On-Premise Systems & Supports NIS2

How Trout Access Gate Secures On-Premise Systems & Supports NIS2

What does NIS2 require in terms of asset inventory?

NIS2 expects organizations to maintain awareness of the systems supporting essential and important services. Practically, this means identifying connected assets, understanding their role and exposure, and being able to demonstrate that this visibility is maintained over time.

Why are spreadsheets or CMDBs not sufficient for NIS2?

Static inventories are typically outdated, incomplete for OT and legacy systems, and disconnected from actual network behavior. NIS2 assumes continuous risk management, which requires visibility based on real activity rather than periodic declarations.

How does Trout Access Gate discover assets without scanning?

Trout Access Gate observes live network traffic at enforcement points. Assets are identified because they communicate, not because they respond to probes. This passive approach is safe for OT environments and does not disrupt operations.

Does this work for OT and legacy equipment?

Yes. The approach is agentless and does not require changes to PLCs, HMIs, appliances, or vendor-managed systems. Visibility is derived entirely from network-level observations.

What type of asset information is collected?

For each asset, Trout can track network presence, observed role, zone, communication peers, and historical activity. This produces a runtime view of the environment rather than a static inventory.

Can this help during an incident or NIS2 reporting event?

Yes. During an incident, IT teams can immediately restrict permissions to block unintended communications and quickly modify security enclaves to quarantine affected systems with a single action. At the same time, retained asset and communication history allows teams to scope impact accurately and support NIS2 reporting with evidence of both exposure and response actions.

Does Trout require cloud connectivity to provide visibility?

No. Trout Access Gate operates fully on-premise. Visibility and inventory are maintained locally, which is suitable for environments with data residency, availability, or connectivity constraints.

Summary of Trout Access Gate and NIS2 Coverage

Trout Access Gate helps organizations meet NIS2 visibility and asset-management requirements by providing continuous, on-premise insight into IT and OT environments. It passively observes live network traffic to automatically identify connected assets, their roles, and their communication flows, without agents, scans, or changes to legacy systems.

This real-time inventory replaces static spreadsheets and periodic audits, giving IT teams an accurate view of systems supporting essential and important services.

During incidents, teams can scope impact based on actual activity and take immediate action by restricting permissions or modifying security enclaves to quarantine affected systems.

The result is a defensible, repeatable foundation for NIS2 risk management and reporting, suitable for industrial sites, regulated facilities, and other on-premise environments.
