OT / SCADA Hardening

Comprehensive protection for your operational technology environment, network hardening, protocol-aware access controls, anomaly detection, and continuous monitoring of SCADA masters, RTUs, and HMIs. We understand the protocols, the operational constraints, and the real-world risks of protecting systems that can never go down.

Our Process

How we protect your OT environment

OT security demands a different approach than IT. Every action is coordinated with your operations team, every change is tested before production, and every control is designed to protect without interfering with real-time operations.

01

OT Asset Discovery

We build a complete inventory of your OT environment, SCADA masters, RTUs, PLCs, HMIs, historians, and every network device in between. You can't protect what you can't see, and most organizations have assets they've forgotten about.

02

Risk Assessment

Every asset is evaluated for exposure, unpatched firmware, default credentials, unnecessary services, insecure protocols, and network accessibility. We map attack paths from the corporate network to critical OT systems.

03

Protection Design

We design a layered protection strategy tailored to your operational constraints, access controls, network segmentation, protocol-aware firewall rules, and monitoring coverage that doesn't interfere with real-time operations.

04

Implementation

Our engineers deploy every control hands-on, configuring firewalls, standing up jump hosts, hardening access paths, and deploying monitoring sensors. Every change is coordinated with operations and tested before going live.

05

Monitoring Integration

OT network traffic is integrated into TITAN's OT monitoring module for real-time protocol analysis, anomaly detection, and automated alerting on unauthorized commands, configuration changes, and network deviations.

06

Ongoing Management

We provide ongoing management of your OT security controls, rule updates, access reviews, vulnerability tracking, and incident response support. Your OT environment stays protected as it evolves.

Capabilities

What we deliver

SCADA Network Hardening

Systematic hardening of SCADA network infrastructure, disabling unnecessary services, securing management interfaces, and eliminating default credentials across all OT devices.

Access Control Implementation

Role-based access controls for OT systems with individual accountability, session logging, and separation of duties between operators, engineers, and administrators.

Protocol-Aware Firewall Rules

Firewall policies that understand Modbus, DNP3, and IEC 61850 at the application layer, allowing legitimate SCADA commands while blocking unauthorized function codes and write operations.

Jump Host / Bastion Deployment

Hardened jump hosts for all OT network access, eliminating direct connections from IT to OT and providing a single, auditable, and controllable access point for all OT administration.

Remote Access Security

Secure remote access for field personnel and vendors with MFA, session recording, time-limited access windows, and approval workflows, because third-party access is one of the biggest OT risks.

OT Network Monitoring

Deployment of passive network monitoring sensors that analyze OT traffic in real time, detecting anomalous communications, unauthorized devices, and changes to control system configurations.

TITAN OT Module Integration

Full integration with TITAN's purpose-built OT monitoring module for protocol-aware alerting, asset tracking, vulnerability correlation, and unified IT/OT security visibility.

NERC CIP Compliance Alignment

Every control we deploy maps to applicable NERC CIP requirements, electronic security perimeters, system security management, access management, and monitoring controls.

Why SkyHelm

The right team for your OT security

Our Engineers Understand OT

We don't send IT security consultants to protect your OT environment. Our OT engineers understand Modbus function codes, DNP3 data objects, and why you can't just reboot a PLC. We speak your operations team's language.

Zero Operational Disruption

Every implementation is planned around your operational schedule, tested in controlled conditions, and deployed with rollback procedures. We've never caused an operational disruption, and we never will.

We Don't Leave Until It's Working

OT protection isn't a report you file, it's infrastructure you operate. We stay until every control is deployed, every sensor is reporting, every access path is locked down, and your team is trained to maintain it.

Continuous Protection Through TITAN

Every OT protection engagement integrates with TITAN for 24/7 monitoring, alerting, and incident response. You don't just get point-in-time security, you get persistent, ongoing protection for your most critical systems.
