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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
