Digitally Fortified Industrial Networking
At Gridlink IT, we understand that the integrity of your energy infrastructure depends not only on physical deployment, but also on how securely it’s designed, configured, and maintained. Our Digitally Fortified Industrial Networking service is focused on building secure-by-design technology environments for SCADA systems, RTACs, substations, control houses, and field-deployed energy assets. We ensure every system is hardened, monitored, and deployed using proven standards from day one—reducing exposure and preventing operational disruptions.
Digitally Fortified Industrial Networking
Securing Critical Infrastructure from Day One
As cyber threats increasingly target energy and industrial control systems (ICS), our approach combines utility-specific cybersecurity frameworks with practical field experience. We align with NERC CIP, NIST 800-82, IEC 62443, and internal utility guidelines to ensure your deployment is not only functional—but also resilient and compliant.
OUR BENEFITS
Why Clients Choose GridLink IT
Pre-Deployment Cyber Risk Assessments
We conduct detailed risk assessments of your network topology, connected devices, and access points before deployment. This includes identifying vulnerabilities, legacy risks, and insecure communication channels. The result is a tailored cybersecurity plan aligned with your SCADA, RTU, and control system architecture.
Secure Configuration & Hardening of Network Devices
Gridlink IT configures routers, firewalls, switches, and RTACs using vendor-recommended security settings. We disable unused ports and protocols, enforce password policies, segment traffic, and enable logging and alerting. Our supported platforms include Fortinet, Palo Alto, Cisco, SEL, Cradlepoint, and others.
Firewall Policy Design & Access Control
We implement least-privilege firewall policies to control inter-zone traffic (e.g., corporate-to-SCADA). This includes access control lists (ACLs), VLAN segmentation, and secure remote access with IPsec VPNs and MFA. All policies are logged and auditable.
SCADA and RTAC Communication Security
We secure automation traffic by encrypting or isolating data between SCADA masters, RTUs, and IEDs. Our services include configuring serial-to-IP gateways, securing Modbus/DNP3 traffic, and enabling monitored VPN/MPLS links with automatic failover.
Deployment Best Practices for Critical Infrastructure
Gridlink IT follows structured deployment processes for secure installations. These include pre-staging, version-controlled configurations, proper documentation, environmental hardening, cable labeling, and commissioning support. All work is validated against project diagrams.
Post-Deployment Monitoring & Incident Readiness
After deployment, we enable remote logging and alerting across firewalls and gateways. We assist with incident response planning and support integration with centralized monitoring systems and SIEM tools.
