The Dragos OT Cybersecurity Assessment gave us exactly what we needed - a clear picture of our security gaps and a prioritized roadmap to address them. The crown jewel analysis alone transformed how we allocate our security resources. We now focus on protecting what truly matters to our operations rather than trying to secure everything equally.

Starting with the Architecture Review helped us establish a security baseline without overwhelming our team. Dragos experts understood our operational constraints and provided recommendations we could actually implement. The topology review revealed network segmentation issues we didn’t know existed, potentially saving us from a major incident.
OT Security Manager, Water Treatment Facility -
The comprehensive OTCA assessment was a game-changer for our mature security program. The threat discovery and IOC sweep components found suspicious activities our existing tools missed. Having all ten assessment modules gave our board complete confidence in our security investments and helped justify additional resources for critical improvements.

Our assessments combine deep industrial expertise with flexible delivery options and platform-enhanced visibility to provide actionable guidance tailored to your OT environment.
Your choice depends on your current OT security maturity. Organizations just starting should begin with Compromise Assessment (CA) or Architecture Review (AR). Those with established programs can choose Cybersecurity Architecture Design Review (CADR). Mature organizations benefit most from the comprehensive OT Cybersecurity Assessment (OTCA) with all ten modules. We help you determine the best fit during initial consultations.
Crown jewel analysis identifies and prioritizes your most critical assets— systems whose compromise would cause severe operational impact. We analyze dependencies, vulnerabilities, and current protections around these assets. This helps you focus limited resources on protecting what matters most rather than trying to secure everything equally. The analysis includes asset mapping, impact assessment, and specific protection recommendations.
Assessment duration varies by option selected. Basic Architecture Reviews typically take 1-2 weeks including interviews and analysis. The comprehensive OTCA assessment requires 3-4 weeks for data collection, interviews, technical analysis, and reporting. We work with your schedule to minimize operational disruption, conducting interviews and reviews at your convenience while automated tools collect network data in the background.
Yes, several assessment modules specifically look for threats. The Indicators of Compromise (IOC) Sweep searches for known attack patterns, while Threat Discovery uses proactive analysis to find hidden threats that bypass existing defenses. If we discover active threats or compromises, we immediately notify you and can provide incident response support. These threat hunting components are included in all assessment options except the basic Architecture Review.
The Dragos Platform automates network traffic capture and analysis, enabling weeks of continuous data collection for more complete asset discovery and vulnerability identification. It provides risk-prioritized vulnerabilities with “now, next, never” guidance and delivers high-fidelity evaluation of any existing compromises. While not required for all assessments, the platform significantly enhances visibility and accuracy of findings.
We recommend annual assessments to track maturity progress and address evolving threats. Organizations should also conduct assessments after significant changes like network modifications, new system deployments, or security incidents. Start with a foundational assessment to establish baseline, then use periodic assessments to measure improvement and identify new risks. Many clients progress through our assessment options as their security programs mature.
