OT CYBERSECURITY - INDUSTRIAL CONTROL SYSTEM
Your IT team can't
protect your plant floor.
OT networks — PLCs, SCADA systems, HMIs, and industrial devices — have fundamentally different security requirements than IT infrastructure. LCS brings deep OT expertise and a Fortinet partnership to protect the systems that keep your plant running.
Request a Free AssessmentCritical Flat IT/OT network — no segmentation
A breach on the business network reaches your PLCs and SCADA directly. One infected laptop = potential plant shutdown.
Critical Remote access without industrial-grade security
VPN access to OT systems without MFA, session logging, or access controls is one of the most common attack vectors in manufacturing.
High Unpatched legacy devices with no visibility
Older PLCs, HMIs, and network switches running outdated firmware with no monitoring — you won't know there's a problem until production stops.
LCS addresses all of these.
Network segmentation, secure remote access, OT-aware monitoring, and Fortinet industrial firewalls — deployed by engineers who understand your process.

We'll identify what should be monitored and how - at no cost.
Confidential. We take your security as seriously as you do.
WHAT WE DO
OT security built by people who
understand your process.
Generic IT security firms don't understand PLCs, SCADA protocols, or why you can't just patch an HMI mid-shift. We do. Every security recommendation we make accounts for operational reality - because we're automation engineers first.
OT Security Assessment
A thorough audit of your OT network — device inventory, vulnerability identification, network topology review, and a prioritized remediation roadmap.
Network Segmentation
Proper IT/OT network separation using industrial firewalls and DMZ architecture — so a breach on the business side can't reach your plant floor.
Secure Remote Access
Replace risky VPN setups with OT-appropriate remote access — multi-factor authentication, session recording, and role-based access to specific devices and systems.
OT Network Monitoring
Continuous visibility into OT network traffic — anomaly detection, unauthorized device alerts, and protocol-aware monitoring that understands Modbus, EtherNet/IP, and Profinet.
Compliance Support
NERC CIP, NIST CSF, ISA/IEC 62443 alignment — we help you document controls, close gaps, and prepare for audits without disrupting operations.
Incident Response Planning
OT-specific incident response playbooks, backup and recovery procedures for control systems, and staff training — so your team knows exactly what to do if an attack occurs.
FORTINET AUTHORIZED PARTNER - OT SECURITY
Industrial-grade security hardware from the OT security leader
Fortinet's OT security portfolio is purpose-built for industrial environments — ruggedized hardware, industrial protocol support, and centralized management that works in your plant, not just your data center. As an authorized Fortinet partner, LCS designs, supplies, and deploys these solutions with deep OT context.
FortiGate Industrial Firewalls
Ruggedized next-gen firewalls for OT environments with industrial protocol deep inspection
FortiSwitch OT Series
Industrial-grade managed switches built for plant floor conditions and OT network segmentation
FortiNAC

FortiSIEM / FortiSOC
OT-aware SIEM and security operations — detect threats across IT and OT in a single pane
OT CYBERSECURITY - FOOD PROCESSING CLIENT
Segmented a flat IT/OT network across two facilities. ISNetworld compliant in 90 days.
A regional food processor had their PLC network on the same flat network as corporate IT - a single misconfigured workstation away from a full plant shutdown. LCS designed and implemented a segmented OT architecture using Fortinet industrial firewalls, established secure remote access with MFA, and completed documentation for ISNetworld compliance in 90 days.

HOW IT WORKS
From assessment toprotected plant
Security without operational disruption. Every step is planned around your production schedule.
STEP 01
Free OT Assessment
We review your current network topology, device inventory, and remote access setup. You get a prioritized risk report — no cost, no obligation.
STEP 02
Architecture Design
Network segmentation plan, firewall placement, secure access architecture, and monitoring strategy — designed around your process requirements.
STEP 03
Implementation
Hardware deployment, firewall configuration, and network changes scheduled around your production — minimizing exposure during the transition.
STEP 04
Monitoring & Support
Ongoing OT network monitoring, alert management, and periodic security reviews — so your protection evolves as threats evolve.
WHY LOGIC CONTROL SYSTEMS
OT security from people who
speak your language.
We understand OT — not just IT
We're automation engineers who added cybersecurity expertise — not IT consultants who added an OT practice. We know why you can't patch a PLC mid-production and design accordingly.
Authorized Fortinet OT partner
We supply, configure, and support Fortinet industrial security hardware — purpose-built for plant floor environments, not adapted from data center products.
Security without stopping production
Every change is planned around your schedule. We've never caused unplanned downtime implementing security — because we know what's at stake if we do.
ISNetworld & compliance experience
We help manufacturers meet ISNetworld, NERC CIP, and customer-specific OT security requirements — with documentation your procurement and safety teams can actually use.
Single partner for OT security + automation
Your PLC programmer and your OT security engineer at the same company. Changes to control systems are automatically evaluated for security impact — no coordination gap.
Ongoing monitoring — not a one-time audit
A one-time assessment tells you where you are today. Ongoing OT monitoring tells you what's changing — new devices, unusual traffic, emerging threats — before they become incidents.
Don't wait for an incident to find your gaps.
A free OT security assessment gives you a clear picture of your risk - and a prioritized plan to close it.
No cost. No obligation.
