Engagement Scope

Key components of our Secure Remote Access

A structured, defined delivery model ensuring you receive actionable outputs and tangible improvements to your operational security posture. Built specifically for industrial automation and critical infrastructure without risking production uptime.

Zero-Trust Network Access (ZTNA)

Zero-Trust Network Access (ZTNA)

Replace legacy always-on VPNs with identity-aware, least-privilege remote access tailored for plant floors.

Time-Bound Just-In-Time Access

Time-Bound Just-In-Time Access

Grant vendor and maintenance engineers access only during authorized maintenance windows.

Multi-Factor Authentication (MFA)

Multi-Factor Authentication (MFA)

Enforce robust MFA at the DMZ gateway before any external connection is permitted into plant subnets.

Full Session Recording & Auditing

Full Session Recording & Auditing

Record video and keystroke logs for every remote engineering session for audit compliance and incident investigation.

Granular Asset-Level Restrictions

Granular Asset-Level Restrictions

Restrict remote users to specific controllers and ports, preventing unrestricted lateral access across the facility.

Secure Remote Access Operational Challenge
The Operational Challenge

Protect your infrastructure from evolving threats.

Zero-trust architecture for vendor and remote engineering access.

OT SECURITY METHODOLOGY

Proven 4-Stage Methodology for Secure Remote Access

Our structured engineering methodology is designed specifically for operational technology and industrial control environments. Every phase is executed passively with strict change governance, ensuring zero disruption to live manufacturing and continuous compliance with IEC 62443.

Zero operational disruption to live plant controls
Aligned with IEC 62443 & Purdue architecture
