What Trout Access Gate Does (High Level)
On-Premise Appliance That Protects Without Disrupting
Trout Access Gate is an on-premise, plug-and-play appliance that brings CMMC-required controls to your factory, without disrupting production or rebuilding your network.
Localized Enclaves
Create secure micro-zones around legacy machines, file servers, and operator workstations.
Enforces segmentation (AC, SC controls)
Access via M365 + MFA
Use your existing Microsoft 365 login for controlled, time-bound access — no new accounts to manage.
Meets identity & access (IA, AC controls)
Integrated Logging & Monitoring
Capture all user sessions and traffic locally; forward logs to your SIEM.
Audit & incident response (AU, IR controls)
Encrypted Traffic & DNS Protection
TLS proxy encrypts every connection; DNS firewall blocks malicious exfiltration paths.
Secures communications (SC controls)
Fast & No Disruption
Plug it in — no readdressing, no VLAN changes, no downtime during install.
How It Works
How Trout Protects On-Premise Assets with Enclaves
From day one, your legacy systems are isolated, secured, and auditable — while operations continue uninterrupted:
Connect to OT network: connect Trout Access Gate with existing Router
Define enclave boundaries: choose which devices, servers, or zones to protect
Policy & access integration: map roles via Azure AD/M365, set time windows, MFA
Monitoring & enforcement: traffic, logs, DNS, alerting, automated documentation
Audit → compliance evidence: built-in reports, logs, and access trails
Who Gains Most from CMMC Enclaves?
Legacy-heavy manufacturers — those with decades-old PLCs, HMIs, CNCs, or SCADA systems
Contractors in DoD chains — small/mid-tier firms facing CMMC Level 2 audits
OT/IT hybrid shops — needing to span IT and OT safely
Firms avoiding costly network overhauls — want compliance without re-cabling

In Summary - CMMC Solution for Legacy Systems
Most factories preparing for CMMC compliance still rely on legacy industrial equipment — machines that run reliably but can’t be patched, encrypted, or managed by modern security tools. From older PLCs and CNCs to legacy HMIs, these systems fall under CMMC’s category of “specialized assets.” They can’t support agents or updates, yet they handle critical production data and Controlled Unclassified Information (CUI).
Traditional, agent-based security solutions often fail in these environments. Installing software on controllers or redesigning VLANs risks halting production and invalidating warranties. That’s why more manufacturers are turning to on-premise CUI enclaves — purpose-built hardware that creates a secure overlay around unpatchable devices instead of changing them.
The Trout Access Gate is a plug-and-play OT security appliance that brings your legacy systems into CMMC scope without downtime. Installed on-premise, it automatically builds encrypted micro-zones around industrial assets, controls access through Microsoft 365 and MFA, and continuously logs events for audits. In hours, your shop floor gains segmentation, encryption, and monitoring — all the CMMC control families (AC, IA, SC, AU, IR, CM) — without touching your existing network.
This CMMC enclave for OT keeps production live while satisfying audit requirements. It eliminates tool sprawl, VLAN redesigns, and cloud dependence — everything operates locally, under your control. Factories across the U.S. have already used Trout’s enclave to achieve CMMC readiness for factories and DFARS / NIST 800-171 compliance with no disruption to their operations.
