Cyber-Physical Security Advisory

The door and the network are the same perimeter.

Cyber, physical, and operational systems now share identity, infrastructure, vendors, and failure paths.

SGS helps leadership understand those dependencies, close cross-domain attack paths, and protect the operations the business cannot afford to lose.

Security domains have converged. Most operating models have not.

Identity platforms control access to cloud systems, facilities, vendors, and critical operations. Building systems and industrial environments now depend on enterprise networks. A compromised account can create physical access. A facility intrusion can expose digital systems.

Defending these domains separately leaves the seams unowned. SGS brings them into one risk, architecture, and decision model.

See How We Work
Cutaway of a corporate facility at night: an amber path runs from a phished laptop up to the cloud platform, down through the server room and building systems, and ends at a door standing open with its badge reader glowing green
One path of many: a phished vendor credential reaches the cloud identity provider, pivots into the building-management network, and releases a door.

Technical depth for complex systems. Decision clarity for leadership.

SGS connects the technical control environment to the decisions executives and boards must make.

Cyber and Identity

Secure the control planes governing people, machines, cloud resources, privileged access, vendors, and enterprise systems.

  • Identity-driven attack paths mapped end to end
  • Privileged, machine, and third-party access under one review
  • Zero-trust operating models grounded in how work actually happens

Cyber-Physical and OT

Secure the connections among enterprise IT, operational technology, facilities, access control, video, building systems, and mission-critical infrastructure.

  • IT/OT segmentation designed around operations, not against them
  • Badge, video, and building systems treated as tier-one infrastructure
  • Vendor remote-maintenance paths brought under one review

Crisis, Resilience, and Incident Command

Build the decision rights, escalation paths, communications, and recovery priorities required when technical disruption becomes an enterprise crisis.

  • Decision rights settled before the incident, not during it
  • Exercises built around credible combined cyber-physical scenarios
  • Recovery priorities anchored to the systems the business cannot lose

Executive Security Governance

Translate technical exposure into accountable ownership, defensible priorities, board decisions, and security investment.

  • Fractional security leadership at board altitude
  • Security spend ranked by measurable risk reduction
  • AI adoption governed before it becomes exposure

Security shaped around how your organization actually operates.

Different environments create different dependencies, attack paths, and consequences. SGS begins with the systems the organization relies on, not a generic control checklist.

Perspectives on the systems, threats, and decisions reshaping enterprise security.

Identity is becoming the control plane for both the digital and physical enterprise

Access to cloud platforms, networks, facilities, building systems, vendors, and critical operations increasingly depends on shared identity infrastructure. Most security models still assess those dependencies separately.
