Solutions built for industrial decisions.
Big4 Security combines local decision-support technology, device intelligence, and expert services to help industrial teams understand what is running, what changed, what creates risk, and what should be done next.
Built for environments where uptime, safety, and trust matter every day.
A clear model for complex industrial environments.
Industrial environments are not static. Devices change, vendors connect, maintenance teams adjust configurations, and operational priorities move quickly. Big4 Security brings these signals together into a practical model that helps people on the ground move from uncertainty to action.

SecBox
Local decision support for industrial environments.
SecBox is designed for facilities that need practical OT security, operational visibility, and decision support without depending on cloud connectivity.
It collects evidence locally, maps the environment, tracks changes, correlates risk, and helps teams understand what happened, what changed, and what should be done next.
SecBox is not another dashboard. It is a practical tool for people responsible for keeping industrial environments running.
Local by design
SecBox is built for sensitive, restricted, and industrial environments where cloud connectivity may not be allowed or available.
Focused on decisions
SecBox helps reduce noise by connecting technical evidence to practical questions that local teams need to answer.
Built for site teams
SecBox supports OT, IT, engineering, maintenance, security, and operations teams with context they can use.
Designed for continuity
SecBox helps organizations understand risk while respecting uptime, safety, maintenance windows, and production reality.

From local evidence to clear action.
Industrial teams do not need more disconnected data. They need a clear way to understand what is happening, what matters, and what action should come next.
Collect evidence locally
Gather relevant signals from the facility environment, including assets, connections, changes, logs, configuration data, and available technical evidence.
Map the environment
Create a practical view of devices, relationships, dependencies, communication paths, and operational context across the site.
Correlate risk and context
Connect technical findings with known vulnerabilities, supplier context, device intelligence, compliance needs, and operational impact.
Guide the next decision
Provide clear recommendations that help teams prioritize action, communicate risk, and support operational continuity.

Guide the next decision
Provide clear recommendations that help teams prioritize action, communicate risk, and support operational continuity.
The goal is not to create more alerts. The goal is to help teams make better decisions with the evidence they already have.
Device Heritage
Know what your devices are made of - before they become your risk.
Modern industrial environments rely on hardware, firmware, embedded components, third-party modules, and supplier ecosystems that are often difficult to validate.
Big4 Security Device Heritage helps organizations understand the origin, integrity, ownership, and risk profile of the devices and components used in their environment.
Device Heritage gives SecBox and Big4 Security services deeper context about supplier risk, firmware exposure, component origin, lifecycle status, and operational trust.
Device origin
Understand where devices, components, and embedded modules come from.
Supplier confidence
Support procurement, compliance, and operational decisions with better supplier and component context.
Firmware and component context
Connect firmware, embedded modules, hardware information, and available documentation into a clearer device-risk picture.
Counterfeit and integrity risk
Identify signs of suspicious, unsupported, unknown, or high-risk components before they create operational exposure.
Operational trust
Help teams decide which devices can be trusted, monitored, isolated, replaced, or investigated further.
GridHound
Operational visibility and validation for OT environments.
GridHound supports the operational visibility and validation layer of the Big4 Security solution.
It helps organizations manage OT security workflows with better asset visibility, internal validation, findings management, remediation tracking, and practical security operations.
GridHound is not positioned as a competing product to SecBox. It supports the broader solution model by helping teams manage what they see, validate what changed, and track what needs to be improved.
Asset visibility
Support a clearer view of industrial assets, systems, and relationships across the environment.
Validation workflows
Help teams validate findings, technical assumptions, segmentation, exposure, and configuration-related risks.
Remediation tracking
Track open issues, ownership, progress, and practical steps needed to reduce operational risk.
OT security operations
Support ongoing security workflows in a way that respects industrial constraints and operational priorities.
Expert services for real industrial environments.
Technology is strongest when it is supported by people who understand the environment.
Big4 Security services help organizations assess, validate, respond, and improve across OT, ICS, connected devices, product security, and industrial operations.
OT and ICS Security Assessment
Evaluate industrial networks, assets, architecture, exposure, segmentation, and operational risk.
Architecture and Design Review
Assess whether the environment is designed to support security, resilience, safe operations, and future growth.
Device and Facility Security Assessment
Analyze devices, systems, facilities, and technical evidence to identify weaknesses and hidden dependencies.
Product Security and Embedded Review
Review connected products, firmware, embedded systems, communication paths, and device-level security risks.
Emergency Cyber Services
Support organizations during incidents, disruptions, suspicious activity, or urgent security concerns.
Cyber Financial Services
Provide technical due diligence, cyber risk analysis, and resilience insight for investors, M&A, and strategic decisions.
Built for operational reality.
A facility environment with zero tolerance for disruption.
In one building management environment, the challenge was not only to identify cyber risk. The challenge was to do it without disrupting tenants, systems, building operations, or critical services.
Big4 Security supported the environment with a non-disruptive approach focused on visibility, segmentation, validation, and practical reporting.
Passive discovery
Mapped connected systems and operational dependencies without interrupting the environment.
Tenant-aware segmentation
Supported a clearer separation of systems, zones, access paths, and operational responsibilities.
Non-disruptive validation
Validated risk and exposure while respecting production, building activity, and operational limitations.
Practical reporting
Delivered clear findings and recommendations that could be understood by technical, operational, and management stakeholders.
The result was a stronger monitoring and resilience posture - without a single interruption to daily operations.
This example reflects the kind of operational environment Big4 Security is built to support: complex, connected, sensitive, and always running.
Operators first. Technology second.
We built Big4 Security around a simple belief: security must work in the real world.
Industrial environments are not clean lab conditions. They include legacy systems, production constraints, supplier dependencies, safety requirements, and people who need clear answers under pressure.
Our team brings hands-on experience across OT, cybersecurity, product security, incident response, critical infrastructure, and connected systems. We focus on practical outcomes, not theoretical reports.
Operational mindset
We understand that security decisions must respect uptime, safety, maintenance windows, and production realities.
Field-ready approach
Our work is designed for environments where internet access may be limited, visibility may be incomplete, and decisions still need to be made.
Clear outcomes
We help teams move from uncertainty to action with evidence, context, and practical recommendations.
Bring local clarity to your industrial environment.
Whether you are preparing for an assessment, validating device trust, investigating risk, or planning a SecBox deployment, Big4 Security can help you take the next step with confidence.
