Unknown connected assets
Establish practical visibility into controllers, workstations, gateways, vendor connections, firmware, and the operational dependencies behind them.

Protect operational continuity
Secure the connected building systems that keep facilities safe, productive, and online.
Request an InspectionThe RJY approach
Operational technology requires a practical security approach that respects uptime, safety, legacy equipment, vendor access, and the realities of facility operations.
Problems we solve
Technical problems rarely stay isolated. RJY Group connects symptoms, equipment condition, controls, operating practices, records, and system dependencies so the response addresses what is actually driving risk.

Establish practical visibility into controllers, workstations, gateways, vendor connections, firmware, and the operational dependencies behind them.
Strengthen how vendors and staff reach critical systems through defined authorization, secure access paths, monitoring, and accountable ownership.
Develop segmentation priorities that reduce unnecessary pathways while respecting uptime, safety, legacy protocols, and essential facility workflows.
Translate technical findings into a risk-based sequence aligned with NIST guidance, operational consequence, maintenance windows, and available resources.
Core capabilities
Establish a practical view of connected controllers, workstations, interfaces, and dependencies.
Prioritize exposure and safeguards according to operational consequence and site conditions.
Improve remote support and vendor access practices without obstructing essential work.
How we work
Understand assets, connections, users, and operational constraints.
Translate observations into a risk-based improvement sequence.
Coordinate safeguards with facility teams and technology stakeholders.
Scope priorities
Facility outcomes
Start with the operating need
Tell RJY Group what is happening at your facility, what has already been tried, and what a successful next step should accomplish. We will use those details to shape a focused cyber security for ot and ics conversation.
For an immediate life-safety or facility emergency, use your established emergency procedure. Website enquiries are for assessment, service, and project planning.
Technical questions
Use these answers to prepare an internal discussion, records review, or first conversation with RJY Group.
Involve RJY Group when conditions, recurring faults, planned upgrades, audit findings, staffing constraints, or operational risk require a structured technical review. Early coordination helps clarify dependencies, available records, work windows, responsible stakeholders, and the safest practical next step.
Share the facility location, affected assets, operating symptoms, known history, current maintenance records, urgency, access constraints, and desired outcome. Photographs, trend data, alarm history, drawings, test reports, and stakeholder contacts can help make the first review more productive.
Yes. Planning can account for occupied spaces, critical schedules, restricted access, safety controls, infection-control requirements, academic calendars, production windows, and approved outages. The exact approach depends on site conditions, system redundancy, and the consequence of interruption.
Priorities are developed by considering observed condition, operational consequence, safety, compliance needs, redundancy, service history, maintainability, access, available resources, and timing. This creates a practical sequence instead of treating every finding as equally urgent or equally valuable.
The appropriate records depend on the agreed scope, but work can include condition notes, completed-service documentation, test results, photographs, open issues, corrective recommendations, and next-step priorities. Deliverables should be confirmed before field work begins so expectations remain clear.
Yes. RJY Group can connect building automation, HVAC, standby power, water treatment, technical staffing, and operational technology security where systems interact. Coordinated planning helps teams see dependencies, avoid conflicting changes, and organize work around the facility mission.
Use the enquiry form with the facility, system, concern, timing, and preferred contact, or call the Houston office. An initial conversation can determine whether the next step should be records review, site inspection, technical assessment, service visit, or proposal development.
