Cyber-Physical Security Advisory
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.
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
SGS connects the technical control environment to the decisions executives and boards must make.
Secure the control planes governing people, machines, cloud resources, privileged access, vendors, and enterprise systems.
Secure the connections among enterprise IT, operational technology, facilities, access control, video, building systems, and mission-critical infrastructure.
Build the decision rights, escalation paths, communications, and recovery priorities required when technical disruption becomes an enterprise crisis.
Translate technical exposure into accountable ownership, defensible priorities, board decisions, and security investment.
Different environments create different dependencies, attack paths, and consequences. SGS begins with the systems the organization relies on, not a generic control checklist.
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.
Read the PerspectiveSGS combines decades of security leadership with hands-on understanding of cyber, physical, operational, investigative, and crisis environments. Every engagement is principal-led, vendor-neutral, and designed to produce durable capability rather than dependence.
Senior judgment without layers of junior delivery.
