Cyber Operations and Resilience Services

Fortify Industrial Infrastructure with Operational-Grade Cyber Resilience

Our services combine cutting-edge threat intelligence, operational discipline, and proven frameworks like the CASTLE Method™ and the SANS ICS 5 Critical Controls. We ensure your industrial control systems are not just secure—but resilient and safe.

CASTLE Methodology Integration

Our services are built on the CASTLE Method™ — a comprehensive OT security framework that encompasses:

• Controls: Safeguard ICS protocols (e.g., BACnet, Modbus) and ensure control systems are resilient

• Applications: Secure ICS/OT applications, agents, APIs, and HMIs with WAF and hardened OS baselines

• Systems: Protect all powered devices—PLCs, RTUs, SCADA servers, switches, IoT/IIoT—from threats and misconfigurations

• Threats: Mitigate both insider and outsider threats using ASA (Attack Surface Analysis) and CTL (Cyber Threat Landscape) mapping

• Law: Align with legal and regulatory obligations (FTC, GLBA, NIST, IEC 62443, CISA, Tennessee & Florida state laws)

• Employees: Minimize human error and insider threats through awareness, training, and access control

Core Services

1. OT-Specific Incident Response

2. ICS Network Visibility & Threat Monitoring

• Passive and active collection using the Dragos Platform and Agent

• Monitoring of Layer 1–4 traffic with protocol awareness

• Detection of Living-off-the-Land (LOTL) and ransomware behaviors

3. Secure Remote Access

• On-demand vendor access with MFA and monitoring

• Secure jump-host architecture

• Enforced chokepoints and logging per NIST SP 800-82

4. Risk-Based Vulnerability Management

• Vulnerability triage using CASTLE threat priorities and Dragos Now/Next/Never

• Accurate asset inventories and firmware validation

• Integrated with CMMS, EAM, and OT patch governance

5. Defensible Architecture

• Implementation of segmentation per Purdue Model + crown jewel defense

• Firewalls, DMZs, and microsegmentation design
