OT Red Teaming & Pen Testing

Simulating Real-World Threat Scenarios to Expose Vulnerabilities Across Your Industrial Control Environment

The Challenge

Operational Technology (OT) environments present unique challenges when it comes to penetration testing and red teaming. These systems are often fragile, built on legacy infrastructure, and designed for uptime—not security. Many are not easily segmented from IT networks, creating high-stakes risk if compromised.

      • Inability to safely test live production systems without risking operational disruption

      • Limited or no detection capabilities in legacy ICS/SCADA systems

      • Lack of documentation or visibility into OT assets and configurations

      • Fragmented or outdated access control mechanisms

      • Concerns over compliance with safety regulations and industry standards

Traditional pen testing methods aren’t always suitable for OT systems, which demand deep knowledge of protocols, vendor-specific nuances, and physical process interdependencies.

The Solution

Defy Security delivers safe, controlled, and highly specialized red teaming and penetration testing services tailored for OT. Our team works closely with plant engineers, OT personnel, and security teams to ensure zero disruption while uncovering real vulnerabilities. Services include:

      • OT-aware red team simulations that mimic real-world threat actor behavior

      • Passive and active testing techniques designed to safely evaluate system weaknesses

      • Testing of ICS/SCADA communications, PLC firmware, HMI interfaces, and perimeter defenses

      • Validation of physical and remote access controls

      • Collaboration with engineering staff to ensure findings are both technically accurate and operationally relevant

These engagements help organizations understand how an attacker could gain access, move laterally, and impact production—without putting operations at risk during the assessment.

You can’t protect what you haven’t tested. OT red teaming reveals the cracks in your defenses—before a real adversary does.
