ICS/OT Cybersecurity Implementation
Our Implementation service turns assessment findings and architecture designs into operational security controls. We deploy, configure, and validate every component on-site, working within maintenance windows and operational constraints to deliver hardened infrastructure with zero production impact.
Turning Findings into Operational Controls
An assessment report with 40 findings and no execution plan ends up in a drawer. We have seen it happen. Our implementation service takes those findings and architecture designs and deploys real, validated security controls on your production floor, using your existing infrastructure wherever possible.
Every change is planned within your maintenance windows, coordinated through your change management process, and executed with a tested rollback procedure ready before the first configuration is modified. We baseline traffic before enforcement, validate every rule after deployment, and hand over documented configurations that your team can maintain.
What We Deploy
- IDS and IPS with protocol-aware detection
- Industrial firewall configuration and allow-list rule design
- Network segmentation and zone enforcement
- Managed switch and device hardening
- Secure Remote Access (SRA) platform deployment
- Patch and firmware update implementation
- System-level hardening and validation
Execution Focused
Deploying security controls that work within operational constraints
Engagement Methodology
Each phase is designed to deliver measurable progress while respecting the operational constraints of live industrial environments.
Scope and Readiness Assessment
Review the current network architecture, existing equipment, and implementation plan. Identify dependencies, define maintenance windows, prepare rollback procedures, and establish success criteria for each implementation phase.
IDS and IPS Deployment
Deploy intrusion detection and prevention systems at strategic network points. Configure protocol-aware detection for industrial protocols (Modbus, OPC-UA, EtherNet/IP, DNP3). Tune detection rules against baseline traffic to minimize false positives while maintaining threat visibility.
Firewall Configuration and Rule Design
Configure industrial firewalls with explicit allow-list rule sets based on validated traffic flows. Replace default permit-all policies with documented, justified rules. Implement protocol-level deep packet inspection for OT protocols at zone boundaries.
Network Segmentation Enforcement
Implement zone and conduit architecture across the OT network. Configure VLANs, ACLs, and firewall rules to enforce segmentation between security zones. Validate all legitimate communication flows after enforcement with a structured observation period.
Switch and Device Hardening
Harden managed switches and network devices: disable unused ports, enable port security with MAC limiting, replace default credentials, disable insecure protocols (Telnet, SNMPv1/v2), enable logging and syslog forwarding, and apply configuration baselines.
Secure Remote Access Deployment
Deploy and configure a centralized secure remote access (SRA) platform. Implement MFA, individual credentials, session recording, scheduled access windows, and role-based access controls. Eliminate direct VPN or RDP connections to production systems.
Patch Management and System Hardening
Implement a structured patch management process with risk-based evaluation, vendor coordination, and maintenance window scheduling. Apply OS and application hardening baselines to workstations, servers, and HMIs. Validate all changes against operational requirements before and after deployment.
Frequently Asked Questions
We deploy a full range of OT security controls: industrial firewalls and network segmentation, intrusion detection and prevention systems, secure remote access solutions, endpoint hardening for HMIs and engineering workstations, OT-specific patch management programs, and centralized log collection for monitoring. We work with platforms from Fortinet, Palo Alto, Cisco, TXOne Networks, Nozomi Networks, Claroty, and Dragos depending on what fits your environment and existing infrastructure.
