One model, many operational environments.

Across industries, the challenge is often the same: teams need to understand what is connected, what changed, what creates risk, and what action should come next.

Big4 Security brings together local decision support, device intelligence, operational visibility, and field-tested expertise to help teams move from uncertainty to action.

Industrial sites

Manufacturing, energy, transportation, utilities, and critical infrastructure environments where uptime and safety are part of every decision.

Sensitive environments

Defense, healthcare, smart facilities, and restricted sites where trust, privacy, and local control matter.

Strategic decisions

Investment, M&A, product validation, supplier trust, and technical due diligence where clarity supports long-term value.

Where Big4 Security creates clarity.

Each environment is different, but the work follows a consistent principle: collect the right evidence, understand the operational context, and help the organization make a better decision.

Automotive Manufacturing

Production continuity and plant visibility

Automotive Manufacturing

Operational challenge. Automotive plants depend on connected production lines, robotic cells, PLCs, MES platforms, vendor access, engineering stations, and just-in-time operations. Even small disruptions can affect production, delivery schedules, and supplier commitments.

Big4 Security approach. Big4 Security applies local evidence collection, OT asset mapping, Device Heritage context, and practical validation to help teams identify unmanaged assets, wireless exposure, supplier dependencies, and regulatory readiness gaps. Where relevant, SecBox supports local decision-making at the site level, while GridHound capabilities support visibility, validation, findings management, and remediation tracking.

Outcome

The organization receives better production-line visibility, a clearer view of change and exposure, stronger regulatory readiness, and a practical plan for reducing risk without disrupting operations.

Oil and Gas Operations

Remote-site resilience and industrial control visibility

Oil and Gas Operations

Operational challenge. Oil and gas environments often include remote sites, control rooms, SCADA, safety systems, field telemetry, vendor-managed equipment, and strict operational constraints. Security decisions must respect reliability, safety, and production requirements.

Big4 Security approach. Big4 Security combines site-level evidence collection, architecture review, RF awareness, Device Heritage context, and IEC 62443-aligned gap analysis with a practical understanding of reliability engineering. SecBox can support local evidence collection and decision support in restricted or connectivity-limited environments.

Outcome

The organization gains a clearer view of remote-site risk, safer segmentation decisions, stronger supplier and device context, and a practical roadmap for OT resilience.

Hospitality and Smart Facilities

Connected building systems without operational disruption

Hospitality and Smart Facilities

Operational challenge. Modern facilities rely on building management systems, guest-facing technology, fire and life safety systems, access control, kitchen automation, AV networks, IoT devices, and third-party service providers. These environments must remain available while risk is assessed and improved.

Big4 Security approach. Big4 Security maps connected systems, validates supplier and firmware exposure, supports segmentation decisions, and helps teams understand the relationship between building operations, tenant experience, safety systems, and technology risk. Device Heritage adds context about devices, firmware, suppliers, and operational trust.

Outcome

The organization receives better facility visibility, faster issue response, stronger supplier confidence, and clearer reporting for technical and operational stakeholders.

Critical Infrastructure and Energy

Trusted visibility for high-value infrastructure

Critical Infrastructure and Energy

Operational challenge. Energy and critical infrastructure environments often include substations, remote access paths, engineering workstations, legacy systems, field equipment, and vendor dependencies. The organization must maintain visibility and control without creating unnecessary operational risk.

Big4 Security approach. Big4 Security supports passive visibility, scenario-based validation, vendor-access governance, Device Heritage analysis, and executive reporting aligned with operational risk and resilience priorities. Where cloud connectivity is limited or restricted, SecBox supports local analysis and site-level decision support.

Outcome

The organization gains a clearer infrastructure risk posture, improved governance, stronger resilience planning, and more practical evidence for leadership and compliance needs.

Public Transportation

Service continuity across connected transportation systems

Public Transportation

Operational challenge. Transportation environments include signaling, depot systems, traction power, stations, connected infrastructure, maintenance systems, vendor access, and passenger-impacting services. Security decisions must preserve availability and support regulatory expectations.

Big4 Security approach. Big4 Security combines local discovery, RF mapping, Device Heritage context, operational validation, and implementation planning aligned with transportation security and resilience requirements. SecBox can support site-level evidence collection and decision-making across complex transportation environments.

Outcome

The organization receives better asset visibility, stronger incident readiness, clearer device and supplier context, and improved reporting for operational, executive, and regulatory stakeholders.

Investment and M&A

Technical clarity before strategic decisions

Investment and M&A

Operational challenge. Investors, strategic buyers, and leadership teams need to understand whether a product, architecture, team, roadmap, and market story can support the investment thesis. Cyber and technical risk can affect valuation, integration, execution, and long-term value.

Big4 Security approach. Big4 Security reviews architecture, security posture, product maturity, IP exposure, technical roadmap, ecosystem position, cyber resilience, and key engineering capability. The work combines technical depth with executive-ready reporting that supports investment, acquisition, partnership, or board-level decisions.

Outcome

The organization receives a risk-adjusted technical view that helps leadership make more confident investment, acquisition, or partnership decisions.

Healthcare Crisis Management

Coordinated response for sensitive healthcare operations

Healthcare Crisis Management

Operational challenge. Healthcare organizations must protect clinical continuity, patient-facing services, back-office operations, leadership decision-making, regulatory expectations, and public trust during technical disruption or suspected security activity.

Big4 Security approach. Big4 Security supports a structured response process across technical assessment, containment, executive coordination, communications, recovery planning, insurance support, and governance documentation. The approach is designed to help leadership make clear decisions while technical teams work to stabilize the environment.

Outcome

The organization receives safer operational recovery, clearer leadership coordination, stronger evidence for governance and compliance needs, and a practical path back to normal operations.

Common outcomes across engagements.

Different environments require different methods. But the outcomes that matter are often shared: better visibility, stronger trust, clearer decisions, and less operational uncertainty.

Better operational visibility

Understand assets, connections, dependencies, changes, and technical evidence across industrial and sensitive environments.

Clearer device trust

Use Device Heritage to better understand device origin, supplier context, firmware exposure, lifecycle status, and operational risk.

Reduced downtime risk

Support security decisions that respect uptime, safety, maintenance windows, and production requirements.

Stronger compliance evidence

Create clearer evidence for regulatory, customer, insurance, governance, and internal security requirements.

Practical decision support

Help local and executive teams understand what happened, what changed, what matters, and what action should come next.

Executive-ready reporting

Translate technical findings into clear, practical reporting for leadership, board, investor, operational, and compliance stakeholders.
