Getting Started

Access Gate is an integrated security and compliance platform for industrial & critical sites. It's a integrated solution combining visibility, access control, segmentation, encryption, and monitoring in a plug-and-play appliance.

Designed specifically for environments where traditional security approaches fail: manufacturing floors, process control systems, building automation, and critical infrastructure with older equipment that cannot be upgraded or replaced.

What is Access Gate?

Access Gate solves the fundamental challenge facing IT teams in industrial environments: how do you achieve modern security and compliance without disrupting operations or replacing legacy systems?

Traditional approaches require:

  • Ripping out and replacing equipment that still works
  • Extensive network redesign with VLAN restructuring
  • Installing agents on systems that don't support them
  • Stitching together 5-7 different security tools
  • Weeks or months of downtime for implementation
  • Large capital expenditures with uncertain ROI

Access Gate takes a different approach. It uses modern techniques—software-defined networking, encrypted proxying, and NetFlow ingestion—to deliver network visibility, asset inventory, granular access control, encryption and audit-ready compliance evidence in a single, integrated system.

The Problem: Compliance Tool Sprawl

Most organizations attempting CMMC, NIS2, or IEC 62443 compliance end up deploying:

  • Asset discovery scanner
  • Network access control system
  • SIEM or log aggregator
  • VPN connection & bastion
  • Firewall or micro-segmentation tool
  • Identity and access management platform
  • Network monitoring system

Each tool requires integration, management, and creates gaps between systems. You're left connecting data sources, correlating events manually, and hoping you haven't missed anything during an audit.

Access Gate consolidates these capabilities into one appliance that ticks multiple compliance boxes from day one. One installation. One management interface. One audit trail.

Core Capabilities: One Appliance, Unified Protection

Universal Visibility (IT/OT/IoT)

Automatically discover and profile device on your network from a single console:

  • IT assets
  • OT equipment
  • IoT devices

No agents required. No manual device registration. Plug in Access Gate and see what's happening in your entire environment within minutes.

Identity-Based Access Control

Tie access to who requests it, not where they're connecting from:

  • Grant access to specific users and groups
  • Integrate with external authentication services (Microsoft 365)
  • Multi-factor authentication support
  • Deploy access screen in front of sensitive assets
  • Temporary access for contractors and vendors
  • Session time limits and automatic termination
Network Segmentation Without Redesign

Create protected enclaves around sensitive systems using overlay networking:

  • Zero downtime deployment: no VLAN changes or IP reassignments
  • Micro-segmentation without physical network modifications
  • Uses 100.64.0.0/16 CGNAT address space for virtual network layer
  • East-west traffic control between zones
  • Contain lateral movement and isolate compromised systems
Secure Gateway with Proxy Architecture

All access flows through Access Gate's on-premise proxy:

  • Users never connect directly to protected assets
  • Full protocol inspection (including industrial protocols like Modbus, OPC-UA)
  • TLS encryption for all connections
  • Traffic normalization and validation
  • Works with legacy systems that don't support modern encryption
Real-Time Monitoring & Threat Detection

Continuous visibility into network activity:

  • Live traffic dashboards showing who's accessing what
  • Behavioral anomaly detection
  • Policy violation alerts
  • Connection attempt logging (successful and failed)
  • Protocol-level inspection and reporting
Centralized Audit Logging

Compliance-ready evidence collection from day one:

  • Unified audit trail across all sites
  • Detailed session logs with user, device, timestamp, and action
  • Immutable log storage for forensic analysis
  • Export capabilities for SIEM integration
  • Pre-built compliance reports for CMMC, NIS2, IEC 62443

How Access Gate Works

Access Gate connects to your existing router (or firewall - which often act as router - or switches) or at a key logical point in your network. From there the Access Gate builds visibility and allows you to direct connections to assets, all traffic flows through Access Gate's intelligent proxy.
